From e09b76ea0ed13840426a56f031769f8d4154f34b Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Sat, 1 Aug 2026 09:25:23 -0700 Subject: Add Nostr Wallet Connect (NIP-47) — hal as a wallet service MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Other apps can connect over nostr and pay from this wallet without touching its keys, within a per-payment and daily budget the user sets, revocable at any time. hal holds no native Lightning balance, so every operation runs over Ark: pay_invoice takes the swap bridge when configured and falls back to the ASP's lightning-send, make_invoice mints on the ASP. NWC availability therefore tracks Ark availability. - kinds 13194/23194/23195, nip44_v2 and nip04, replying in whichever scheme the request used; every request gets a reply so clients never hang - each connection gets its own service keypair, so revoking one can't affect the others and none is tied to the user's nostr identity - budgets are checked BEFORE spending, not reconciled after - requests are ignored unless signed by that connection's client key, and replayed/stale events (>120s) can't re-trigger a payment - Settings card to create, show (URI + QR) and revoke connections, and it says plainly that this only works while a tab is open tools/nwc-test.js drives it as a real client: both encryption schemes, budget refusal with a genuine over-limit invoice, unsupported-method errors, and a request from an unauthorized key being ignored.
