From 15e0b236e7ff2cafcb439c891c790deea8ec16a7 Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Sun, 5 Jul 2026 20:39:02 -0700 Subject: Unilateral exit: put vtxos on-chain without the server The trustless backstop behind the Ark card's promise. The vtxo's genesis chain reconstructs to fully-signed txs (keyspend sigs for cosigned/arkoor transitions, preimage script-path for hark leaves); they are zero-fee v3 with P2A anchors, so each hop broadcasts as a [parent, CPFP child] package via esplora POST /txs/package, one confirmed hop at a time (TRUC allows a single unconfirmed parent). After the vtxo tx confirms and the CSV exit delta passes, the claim spends the delayed_sign leaf with only the user key into the wallet's own receive address. Settings gains 'Exit on-chain without the server' with live per-exit status lines; the claim tx is labeled 'Ark exit' in History. Probing uses /tx/:txid (definitive 404), never /tx/:txid/status, which answers confirmed:false for unknown txids. Also: a fresh visitor opening an ark gift link now adopts the gift's network automatically instead of being sent to Settings.
