A new method for using Bitcoin as collateral in cross-chain agent transactions has been proposed, aiming to avoid the need for wrapping or bridging the cryptocurrency. This approach utilizes a hash time-locked contract on the Bitcoin blockchain, which requires a specific preimage to unlock the funds. This preimage is also used to settle a corresponding contract on another chain, such as Ethereum. The system includes a timelock for refunds if the obligation is not met, ensuring that the Bitcoin remains under the agent's control until settlement or refund. AI
