Can an AI agent post Bitcoin as collateral without giving up the keys?

Short summary

Bitcoin's inability to run contracts creates a collateral dilemma for AI agents in cross-chain settlement: wrapping BTC for usability introduces custodial risk, while native collateral vaults lock BTC on-chain via hash-time-lock contracts, moving only a hash between chains to eliminate intermediaries. The vault approach trades continuous margin calls for discrete obligations and coarser timeout windows, but keeps collateral truly trustless. A new MCP server exposes this as tool calls for agent-side collateral logic.

• •Wrapped Bitcoin solves usability but reintroduces custodial risk; vaults eliminate intermediaries but sacrifice continuous margin calls
• •Native collateral stays on Bitcoin via hash-time-lock contracts; settlement information (not the asset) crosses chains
• •MCP server enables agents to reason about collateral as tool calls rather than low-level script mechanics
