* Remove the 'reusable address that can't be tracked' note from the SP receive ↵Adam Soltys2026-06-281-2/+1

* Consolidate coins: a Settings action + a gift-time recommendationAdam Soltys2026-06-281-11/+45
| | | | | | | | | | | | | | | | | - Settings gains a 'Consolidate coins' card (shown when you hold >1 spendable coin): wallet.consolidate() does a max self-send merging them into one, so future sends/gifts use a single input — cheaper and a smaller gift QR. - At gift creation, detect when the gift would bundle several coins (giftCoinSummary returns the input count) and trigger the split/consolidate offer when count ≥ 3 (not just when it frees change). The offer now explains it plainly ('would bundle N coins, costly to claim') and recommends splitting into one coin first, with 'Use N coins anyway' as the explicit opt-out. Verified on regtest: 6 small coins → a 1000-sat gift needs 3 inputs and triggers the offer; consolidate merges them to 1 coin, after which the same gift is a clean single input.

* Fix gift creation silently failing on large (many-input) gifts; one Back buttonAdam Soltys2026-06-281-3/+9
| | | | | | | | | | | - A many-input gift produces a URL too long for a QR, and qrSvg threw — uncaught, inside render() — so the click did nothing and showed no error. Wrap the gift QR in try/catch: render the QR when it fits, otherwise fall back to a 'too large for a QR — use the link' note. The link itself still works. - The split-offer card has its own Back; hide the gift sub-view's outer Back while the split offer is showing, so there aren't two stacked Back buttons.

* Locked gifts: let NIP-07 extension users decrypt in-place, skip the codeAdam Soltys2026-06-281-3/+23
| | | | | | | | | | | | | | The gift payload is now encrypted two ways in the link: under the one-time code (the DM / manual path) AND to the recipient's nostr pubkey via an ephemeral key. When a NIP-07 browser extension (window.nostr) is present, the claim view offers 'Claim with nostr extension' — it checks the extension's pubkey matches the gift, decrypts ctKey via window.nostr.nip44.decrypt, and claims into a fresh wallet with no code. The pasted-code path remains as the fallback for everyone else. Verified: both decrypt paths recover the payload from the blob; a different extension account is rejected.

* Lock a gift to a nostr key: public link, claim code DM'd to the recipientAdam Soltys2026-06-281-12/+132
| | | | | | | | | | | | | | | | | | | | | | | | A gift can now be locked to a recipient's nostr npub. The shareable link (/lg/<blob>) carries the amount + recipient in the clear (anyone can see what it is and who it's for), but the claim payload is encrypted under a one-time code. That code is delivered as an encrypted nostr DM (NIP-04) to the recipient — so only they can read it. They paste the code to decrypt, then claim into a fresh wallet exactly like a normal bearer gift. - nostr.js: parseNostrPubkey/npubOf, encryptWithCode/decryptWithCode (random 32-byte code), fetchNostrProfile, NostrSync.sendDM (broad relays). - wallet.js: lockGift → { blob, claimCode }, previewLockedGift, nostr identity + sendNostrDM. - app.js: gift form gains an optional 'Lock to npub' field that shows the recipient's avatar + name (nostr kind-0 profile); create encrypts + DMs the code (with sent/failed status + a copyable fallback); /lg/ links open a claim view showing the gift + recipient where you paste the code; account settings shows your own npub to share. Verified: code lock/unlock round-trip, a real nostr DM published and read back from relay.damus.io, and the UI loads + renders with no errors.

* Source lists: show only the URL, protocol strippedAdam Soltys2026-06-281-2/+2
| | | | | | | | Drop the human-readable name and the scheme prefix in the data-source and SP-indexer dropdowns, e.g. 'electrum.coinos.io', 'mempool.space/api', 'tweaks.coinos.io'. 'Custom' stays bare. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Show full URLs in the source lists; SP indexer → tweaks.coinos.ioAdam Soltys2026-06-281-2/+2
| | | | | | | | | | | | - Data-source and SP-indexer dropdowns now show the endpoint URL alongside the name (e.g. 'coinos — wss://electrum.coinos.io'), so it's clear where data comes from; 'Custom' stays bare. - The tweak indexer is now served at https://tweaks.coinos.io (was halwallet.app/ sp): a cloudflared route on the bitcoin tunnel → the indexer at :8888, with a DNS CNAME. Verified from a browser: /height, /mempool (1064 items), and /ws all work (the coinos.io Bot Fight Mode challenges non-browser clients only).

* Unify data sources into one list; coinos → electrum.coinos.ioAdam Soltys2026-06-281-50/+21
| | | | | | | | | | | | | | | | | | | - Combined the separate Electrum and Explorer settings into a single data-source list. Each preset knows its type (electrum vs esplora); a custom source's type is detected from its URL scheme (ws/wss → Electrum, http/https → Esplora). The settings UI is now one dropdown + a URL field for Custom, with a one-line note showing the detected/selected type. getBackend/electrumCandidates/resolveHosts derive from the selected source. Old split settings migrate automatically. - coinos now points at wss://electrum.coinos.io (was wss://halwallet.app/electrum). Set up as a cloudflared route on the bitcoin tunnel → the Fulcrum WS (:50003), with a DNS CNAME. Verified the endpoint serves Electrum from a browser (Fulcrum 2.1.1 replies; cloudflare Bot Fight Mode only challenges non-browser clients). Verified: combined list + auto-detection (unit + browser), old-settings migration, regtest data flow unchanged, and the app loads over electrum.coinos.io with no errors.

* Stop input/select fields losing focusAdam Soltys2026-06-281-0/+31
| | | | | | | | | | | | | | | | | Two causes, both fixed: - _scanSpMempool emitted on every WS push even when our pending set was unchanged. The mainnet mempool churns constantly, so this re-rendered the whole app every few seconds, stealing focus mid-type. Now it only emits when our pending SP set actually changes. - render() rebuilds the DOM (replaceChildren), which inherently drops focus. Added focus + caret preservation: capture the focused field's index-path and selection before the rebuild, restore them after. So any render source (poll, payment push, scan) is now invisible to someone typing. Verified via CDP: typing 'bc1q…' in the Send address, caret at 6, then forcing a re-render — focus, value, and caret all retained. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Scan silent payments from each wallet's birth, not the indexer's startAdam Soltys2026-06-281-6/+6
| | | | | | | | | | | | | A freshly-generated wallet can't have received SP before it existed, so set its scan watermark to the current tip on first connect (skipping the whole historical catch-up) instead of scanning from 0. Threaded a 'generated' flag through the create flow (openWallet → enterWallet → activateAccount → load spFresh); imported wallets still scan from the indexer start since they may have prior receipts. Verified on regtest: a fresh wallet skips the block-5780 receipt (watermark=tip, balance 0); the same seed imported finds it. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Wire in-app back buttons to pop browser historyAdam Soltys2026-06-271-6/+15
| | | | | | | | | | | | | | The screen-changing back buttons (tx detail, gift sub-view, all-gifts, bump, account settings, accounts) now call goBack(), which does history.back() when there's an entry to pop — so they no longer push a duplicate entry. Falls back to an explicit parent-screen navigation when there's no in-app history (e.g. reloaded straight into a sub-screen). Modal-dismiss buttons (revoke, rename, password, draft) are unchanged — they don't touch nav state. Verified via CDP: detail (i=2) → in-app back → i=1 (popped) → Forward restores the detail. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Browser history / back-button navigationAdam Soltys2026-06-271-0/+50
| | | | | | | | | | | | | | Mirror the app's screen position (screen, tab, txDetail, bump, giftsAll, giftMode, claimStep) into the browser history, so Back/Forward (and Android system back) move between screens actually viewed. render() snapshots just these nav fields and pushState()s on change — incidental re-renders (typing, polling) don't add entries. popstate restores the snapshot and re-renders. History-API calls are guarded so they can never break a render. Verified via CDP: tab nav and tx-detail push entries; Back/Forward (incl. A→B→A) restore the right screen and the DOM follows.

* Make silent-payment receives first-class in the UIAdam Soltys2026-06-271-51/+24
| | | | | | | | | | | | | | | - One Receive card with an Address ⇄ Silent payment toggle (no separate card, no BIP-352 badge, no scan-status line or Rescan button — discovery is automatic). - SP receipts appear in History like normal payments: wallet.history merges BIP84 txs with per-tx SP receive rows (spTxRows), newest first; the detail view and pagination use it. SP outputs carry a firstSeen timestamp. - Receive description simplified to 'A reusable address that can't be tracked.' - Removed the '· Silent payment' tag from the Send recipient line. Verified on regtest: a received SP shows in history and balance with no manual scan. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Auto-scan for silent payments + fold found value into balanceAdam Soltys2026-06-271-7/+11
| | | | | | | | | | | scanSilentPayments() now recomputes the balance so received SP value shows in the wallet total (not just the Receive card), and gains a silent mode. It's triggered automatically after each full scan and on the poll loop (incremental, cheap), so payments appear without tapping anything. The Receive card now shows a status line ('Watching for payments' / found amount) with a small manual Rescan instead of a primary Scan button. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Wire silent-payment receiving into the wallet (scan + balance + UI)Adam Soltys2026-06-271-5/+67
| | | | | | | | | | | | | | | | | | | wallet.js: scanSilentPayments() pulls the indexer's /scan range, matches outputs on-device, and verifies each is unspent via the chain backend; spUtxos + balance are tracked in their own bucket (one-time taproot keys), persisted in the cache. silentPaymentsAvailable()/spBalance() expose state. app.js: the Receive tab shows the reusable sp address (QR + copy), a 'Scan for silent payments' button, and the found amount; Settings gains a per-network SP indexer picker (under Data source) with custom/self-host support. sp-indexer.js: added /scan/{from} so a client fetches a whole range in one request instead of one fetch per block. Receiving verified end-to-end on regtest (scan finds the output, 49,999,800 sat confirmed). Spending SP outputs is the remaining piece.

* Don't flash 'Payment received' on import for a pre-existing depositAdam Soltys2026-06-271-1/+6
| | | | | | | | | | | On a fresh open, receiveSeenIndex was baselined to the pre-scan frontier (line 691), so the moment the socket's reconcile credited a deposit that predated the open, nextReceiveIndex advanced past it and the celebration flashed for ~2s until the post-scan baseline caught up. Leave receiveSeenIndex null until that final baseline for fresh opens (matching the documented intent); the != null guard then suppresses the flash. Same-session refreshes still use the persisted ack. Co-Authored-By: Claude Opus 4.8 <[email protected]>
* Payment details: say "Pending", not "Pending (in mempool)"Adam Soltys2026-06-271-1/+1
| | | | | | | The mempool parenthetical is jargon for non-technical users; the status line now reuses the plain `pending` string. Drop the now-unused pendingInMempool key. Co-Authored-By: Claude Opus 4.8 <[email protected]>
* Allow importing a seed from a watch-only wallet's settings pageAdam Soltys2026-06-271-4/+15
| | | | | | | | | | The recovery-phrase section of the per-wallet settings page now shows an Import seed action for watch-only wallets, with the load-seed card inline. The load-seed flow takes an account id (defaulting to the active wallet), so it can upgrade a specific watch-only wallet — validating the entered seed against that wallet's xpub before making it spendable.

* De-dup wallet settings; reorder per-wallet page; lowercase 'this'Adam Soltys2026-06-271-93/+21
| | | | | | | | | | The global Settings tab no longer shows the recovery phrase / public key — those live only on each wallet's settings page now (the watch-only 'load seed' upgrade stays in the global tab since it targets the active wallet). On the per-wallet page, recovery phrase moves to the top and auto-logout to the bottom. Removes the now-dead pubkeyCard/autoLockCard. Lowercases 'THIS' in the auto-logout copy. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Add a per-wallet settings page (cog from the accounts list)Adam Soltys2026-06-271-2/+86
| | | | | | | | | | The accounts list now shows a settings cog (instead of a rename pencil) that opens a per-wallet settings page: edit name, set auto-logout (moved here from the global settings tab), reveal the recovery phrase, and show the public key (zpub) — all read from the account itself, so it works for any wallet, not just the active one. Room for more per-wallet settings later. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Per-network data source; drop duplicate regtest fields; add mutinynetAdam Soltys2026-06-271-29/+8
| | | | | | | | | | | | | | The network card is now just the network picker. Each network's endpoints (Electrum server + block explorer) live solely in the Data source card, whose options change per network and are stored per network (so switching networks remembers each one's choice). Removes the duplicate regtest Esplora/WS fields. Adds mutinynet (signet — testnet address format, explorer at mutinynet.com). Per-network defaults: mainnet → coinos Electrum, testnet/mutinynet → explorer, regtest → local Fulcrum. Fixes tx-explorer links to use each network's web base (no double /testnet). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Make coinos the default Electrum server instead of a separate modeAdam Soltys2026-06-271-13/+5
| | | | | | | | | The data-source picker is now just Electrum vs Block explorer; coinos is the first/default entry in the Electrum server list (our own Fulcrum), with public servers as failover. Drops the standalone 'coinos' mode and the retired watcher shim. Old 'coinos' selections migrate to electrum. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Regtest realtime via a local Electrum-over-WebSocket bridgeAdam Soltys2026-06-271-10/+18
| | | | | | | | | | | | | On regtest there's no realtime push (coinos watcher is mainnet-only), so the UI only updated on the 5–10s poll — a funded tx took a while to appear and a just-mined block stayed "pending" until the next reconcile. electrs speaks the Electrum protocol the watcher already understands, but only over TCP; route it through a small WS<->TCP bridge (see coinos-server/electrum-ws) so the wallet subscribes scripthashes and reconciles instantly on each notification. Data still comes from esplora; this only adds the push channel. Configurable in Settings (default ws://localhost:50003); falls back to polling if unreachable. Co-Authored-By: Claude Opus 4.8 <[email protected]>
* Add regtest network supportAdam Soltys2026-06-271-5/+44
| | | | | | | | | | New `regtest` network (bech32 `bcrt`, testnet version bytes) selectable in Settings, pointed at a configurable local Esplora (default http://localhost:3000). Adds getNetwork/setNetwork + getRegtestEsplora persistence, a regtest branch in resolveHosts, mainnet-only gating for the realtime watcher + Electrum backend, and a Network selector card. Account loading reads the active network. Co-Authored-By: Claude Opus 4.8 <[email protected]>
* Update balance/history optimistically right after a sendAdam Soltys2026-06-261-2/+2
| | | | | | | | | | | | | On the Electrum backend the post-send rescan is many round-trips, so the balance lagged a few seconds. Now a successful broadcast immediately applies the tx locally (applySentTx): drop the spent coins, credit change as pending, add a pending history row, recompute the balance, and emit — so the UI reflects the send instantly. The realtime watcher / backstop poll reconciles and fills in the confirmation once the explorer has indexed it (no immediate rescan, so a not-yet-indexed tx can't briefly revert the optimistic state). Verified the balance/utxo/history math. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Fix broadcast hanging forever on a stalled responseAdam Soltys2026-06-261-1/+4
| | | | | | | | | | | | The Esplora broadcast cleared its abort timer right after fetch() resolved, so the subsequent res.text() body read had no timeout — a stalled response body hung the whole broadcast (and the send spinner) indefinitely, with the tx never reaching the network. Keep the abort timer active through the body read, and add a hard 30s outer timeout in the send handler so a wedged broadcast always surfaces as 'timed out — try again' instead of spinning forever. (The silent-payment tx itself is valid — verified structure + BIP143 signature over the real outputs.) Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Don't hold the send spinner up during the post-broadcast rescanAdam Soltys2026-06-261-1/+4
| | | | | | | | | | broadcast() set the success result but kept ui.busy=true and didn't render until after awaiting wallet.scan(), so the 'Sign & broadcast' button spun for the whole post-send rescan (slow under rate-limiting / on the Electrum backend) — looking stuck even though the tx had already broadcast. Now it shows the success screen the instant the broadcast resolves and refreshes balances in the background. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Confirm before removing a single wallet (like Clear all)Adam Soltys2026-06-261-1/+16
| | | | | | | | The ✕ on a wallet now opens a confirmation screen warning it's removed from this device (keep its recovery phrase; other wallets unaffected) instead of deleting immediately. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Logo returns to the wallet's Receive page; add paste-from-clipboard buttonsAdam Soltys2026-06-261-24/+47
| | | | | | | | | | | - goHome: when a wallet is open, the logo goes to its Receive page (its tabs) instead of the create/import screen — so it's always a way back to your wallet. Only with no wallet open does it show create/import. - Paste buttons: a clipboard 'Paste' icon on the send address field and the import (seed/key/xpub) and 'load seed to spend' fields, filling them from the clipboard. Hidden where the Clipboard read API isn't available. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Add 'Change password' for the saved-to-device vaultAdam Soltys2026-06-261-5/+26
| | | | | | | | | | | A vault exists → Accounts screen shows Change password: enter the current password, then a new one (with confirm; leave blank to remove it). It decrypts the actual vault and re-encrypts it with the new password, so wallets not loaded in the current session are never dropped. Keeps the in-memory password in sync when the vault is already unlocked. Verified the re-encrypt round-trip (old rejected, new works, blank works). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Make auto log-out per-wallet — only signs out the wallet it's set forAdam Soltys2026-06-261-55/+109
| | | | | | | | | | | | | | | | | | The logout timer is now an account setting (stored per account in the session and the durable directory), not a global one, and it removes only that wallet from the device — its session entry, directory entry, cached state (xpub + seed keys), and its vault entry — leaving other wallets untouched. - wipeAccount(id) surgically removes one wallet; the active one falls back to the next account (or the unlock screen). - Background-away timestamp drives per-account evaluation on resume/boot; an armed timer fires for the soonest-due wallet so a blurred-but-visible window still signs out on time. Overdue saved wallets are removed from the vault when it's unlocked (the only point we can re-encrypt it). - New cacheKeyFor() export lets app code target one wallet's cache keys exactly (verified against the wallet's seed/xpub/watch keys). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Auto log-out wipes the saved-to-device vault too (full device wipe)Adam Soltys2026-06-261-13/+6
| | | | | | | | With a logout timer set, signing out now removes everything from the device including the password-protected vault — nothing survives, so the recovery phrase is required to return. Updated the setting copy to say so. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Auto log-out also wipes a blank-password (unprotected) vaultAdam Soltys2026-06-261-0/+11
| | | | | | | | A vault saved with no password auto-unlocks on open, which would undo the sign-out. When a logout timer fires (or a boot is overdue), remove it too — only a password-protected vault survives. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Add auto log-out (background timer) + make vault passwords optionalAdam Soltys2026-06-261-8/+109
| | | | | | | | | | | | | | | | Auto log-out: a Settings option (Never default, 1m/5m/1h/1d) that, after the app has been backgrounded/unfocused that long, signs out completely — clears the session, the watch-only directory, and cached balance/history from the device (only password-saved vault wallets remain). The countdown only runs while the app is hidden/unfocused, never while it's open and focused; a background timestamp covers throttled/discarded-tab cases on resume/boot. Optional vault passwords: drop the 8-character minimum and allow a blank password. A blank-password vault auto-unlocks on open with no prompt (Save to device with no password = just persist). Verified blank round-trip + wrong- password rejection. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Persist wallets as watch-only across sessions; re-enter seed to spendAdam Soltys2026-06-261-24/+135
| | | | | | | | | | | | | | | | | | | | | | | Closing the browser without 'Save to device' used to wipe the wallet entirely. Now every wallet's account xpub is mirrored to a durable localStorage directory (never the seed), so it survives a session wipe as a watch-only entry — you keep seeing balance and history, and re-enter the seed to spend again. - Durable account directory: saveDirectory() mirrors {id,label,xpub} for every account; restore falls back to it as watch-only when there's no session/vault. - Instant view: a full wallet also caches under its xpub key, so the downgraded watch-only shows balance/history immediately (no rescan). Verified round-trip. - Re-enter seed to spend: the Send tab (now shown for watch-only) and Settings prompt for the recovery phrase / xprv; it must derive to this wallet's xpub (verified via accountXpubFor — wrong seed/passphrase rejected), with an option to Save to device at the same time. Upgrade is in place (id/label/cache kept). - Vault merge now dedupes by xpub so saved + non-saved wallets coexist without duplicates. Privacy note: the xpub now persists by default (someone with device access can see balance/history without the seed); 'Remove' clears it.

* Fold the coinos opt-out into a single Data source pickerAdam Soltys2026-06-261-35/+27
| | | | | | | | | | | | | | | | | | | Replace the Esplora|Electrum backend toggle plus the separate 'Instant notifications' on/off with one 'Data source' selector: • coinos (instant) — default; explorer data + coinos push • Block explorer — REST + polling, nothing sent to coinos (the opt-out) • Electrum server — one WS server for data + push (your node / public) Picking a non-coinos source IS the privacy opt-out, so the standalone toggle is gone. A single 'mode' setting drives getBackend()/getRealtimeEnabled(), so the wallet/wsUrl logic is unchanged; existing per-feature settings migrate in (realtime=off → explorer, backend=electrum → electrum). coinos⇄explorer just flips the watcher (no rescan); to/from electrum rebuilds the backend. Sets up cleanly for a future coinos Fulcrum: 'coinos' mode upgrades from REST+watcher to a full Electrum backend transparently. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Add Electrum-over-WebSocket as an alternative data backendAdam Soltys2026-06-261-36/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | Settings → Data source now offers 'Electrum' alongside the Esplora REST explorer. One Electrum WebSocket serves BOTH the wallet's data queries and scripthash push notifications, so pointing Hal at your own Fulcrum/electrs gives a fully self-hosted setup — no coinos, no public REST, nothing shared off your node. - src/electrum.js: ElectrumApi maps the Esplora shapes the wallet consumes onto Electrum methods (scripthash get_balance/listunspent/get_history, estimatefee, transaction.broadcast). electrs has no verbose tx lookup, so it parses raw txs and resolves input values from parent txs to compute fees (cached, in-flight deduped, bounded-parallel). Validated field-for-field against mempool.space: addressTxs (fee/vin/vout/status), getTx, outspend, balance, utxos. - wallet.js: the realtime socket already spoke Electrum's notify protocol; added request/response (_rpcCall) so the same connection answers data calls. Real Electrum notifications carry no tx data, so they reconcile via the backend. Replaced the fragile newline parser with a string-aware brace-depth scanner that handles every framing (newline, one-per-frame, concatenated, split) — fixes a buffer-poisoning hang under concurrent calls; also hardens the coinos watcher path. Esplora stays the default; nothing changes for existing users. Verified end-to-end against blockstream's electrs: concurrent transport, a full fresh-wallet scan (~2s), and the parser unit-tested on all framings.

* Add Silent Payments (BIP-352) sendingAdam Soltys2026-06-251-2/+10
| | | | | | | | | | | | | | | | | Pay sp1… addresses: the wallet derives the one-time taproot output from the recipient's address + the transaction's own input keys (ECDH), so payments are unlinkable on-chain with no interaction. New src/silentpay.js implements the sender derivation + bech32m address decode, validated against the official BIP-352 test vectors (all P2WPKH-input / single-recipient cases pass; the rest exercise input types Hal never spends). buildTx detects sp1… recipients, selects coins against a same-size placeholder taproot output, then swaps in the script derived from the final input set (updateOutput). Works for normal sends, multi-recipient, and send-max. The review screen shows the sp1… address with a 'Silent payment' label (the on-chain output is a derived one-time taproot address).

* Settings: let users opt out of coinos realtime notifications (privacy)Adam Soltys2026-06-251-2/+19
| | | | | | | | | | | The WS watcher is the one place the app shares addresses off-device (it subscribes your scripthashes to coinos to push instant payment updates). Add an 'Instant notifications' toggle in the explorer settings: off means the app never connects to coinos and polls your chosen explorer instead — a bit slower, more requests, but nothing is told to coinos. wsUrl returns null when disabled, so startRealtime cleanly skips the socket and relies on the polling fallback.

* Open block-explorer links via window.open (reliable in standalone PWA)Adam Soltys2026-06-251-3/+10
| | | | | | | | Reorder the already-claimed actions (Create a wallet anyway above the explorer link) and force explorer links to open in a new window/tab via window.open — inside an installed PWA, <a target=_blank> can navigate the app away instead.

* Make the gift-claim wallet provisional until committedAdam Soltys2026-06-251-2/+22
| | | | | | | | | | | Opening a gift link generates a wallet only to claim into. Mark it provisional so bailing from an already-claimed gift (Go to home / logo) discards it instead of leaving an empty account in the session list. It's committed — kept for good — the moment the user claims, chooses 'Create a wallet anyway', or otherwise enters the wallet (incl. a refresh). Critically, commit on claim *success* so the backup step can't discard a wallet that just received funds. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Already-claimed gift: offer 'Create a wallet anyway' or go homeAdam Soltys2026-06-251-4/+9
| | | | | | | | The claim flow already generated a fresh wallet, so the dead-end screen now lets the opener keep it (→ back up the recovery phrase → into the wallet) or head to the home screen. The backup step's copy adapts (Claimed! vs Your new wallet). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Persist the active tab + open tx across refreshAdam Soltys2026-06-251-1/+13
| | | | | | | | | Save the wallet-screen nav (tab and open tx detail) to sessionStorage on each render and restore it on load, so refreshing keeps your place instead of jumping back to Receive. A restored tx detail re-fetches its fee/details if missing. Gift links still open the claim screen. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
* Lazily fetch a receive's fee when opening its detailAdam Soltys2026-06-251-1/+25
| | | | | | | | | A watcher-credited receive arrives with no fee (the push can't compute it from the raw tx, and the reduced reconcile doesn't revisit the now-used address). On opening the tx detail, fetch the full tx from the explorer to fill in the fee (and confirmations) — works for pending mempool txs too.

* Celebrate a received payment once; don't re-show after refresh/reopenAdam Soltys2026-06-251-3/+7
| | | | | | | | Persist the receive-ack the moment the 'Payment received!' screen is shown (not only on tap), so refreshing or navigating away without tapping won't bring it back. It still stays visible in the current session until dismissed. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
