Anatomy of an Ark Wallet
summary
A Rust SDK called Bark implements the Ark protocol and ships a REST daemon, a web wallet prototype, and Rust SDK with six bindings so teams can embed Ark payments, BIP321 URIs, and built‑in BDK on‑chain wallets. It uses virtual UTXOs (VTXOs) with a 30‑day VTXO expiry and a default 24‑hour refresh threshold; refreshes are automatic or delegated to cosigners. Emergency exits are implemented but slow and require on‑chain fees (emergency exit via on‑chain unwind). Backups are SQLite now; BIP39 recovery is planned.
