A Bitcoin developer has unveiled a seamless bridge between Bitcoin and Cardano applications, allowing Bitcoin wallets to interact directly with Cardano's ecosystem. This breakthrough in blockchain interoperability was showcased through a smart contract on Plutus V3, enabling users to send ADA, manage tokens, and stake in Cardano pools without needing a new wallet. This innovation took Cardano founder Charles Hoskinson by surprise and has the potential to revolutionize cross-chain connectivity. The developer explained that this bridge was built using a combination of tools and protocols, including the Cardano smart contract language aiken and the address programmability enhancer CIP69. The announcement has generated interest among enthusiasts, who are eager to understand the mechanics and applications of this new bridge. The developer clarified that Bitcoin users can sign Cardano actions from their existing wallets, and these actions will be executed by Cardano nodes if the signature is verified. This bridge opens doors for onboarding users from outside the Cardano ecosystem and facilitates interactions like airdrops and liquid staking without requiring users to change wallets. The contract validates signatures to ensure secure cross-chain operations.
