summary
A trustless Bitcoin vault uses programmable Bitcoin UTXO and Taproot script to lock BTC on-chain while an Ethereum BTC vault manager contract tracks vault metadata; off‑chain actors (vault providers, challengers, liquidators) coordinate deposits, redemptions and disputes. Proof‑of‑concept runs on Bitcoin and Ethereum mainnets lock 9,000 satoshi (~$8) and mint 1 USDC on Morpho, with a 2–3 day challenge period, one‑vault‑one‑app atomicity, no ERC20 wrapper by default, and the protocol currently in audit.
