Wu said that Trac Systems' Tap Protocol has launched what is said to be the first Bitcoin native smart contract and DeFi tool that runs directly on the Bitcoin Layer 1 mainnet, relying on the Ordinals meta-protocol. The team said that this breakthrough allows smart contracts, exchanges, and liquidity pools to be independent of Layer 2 solutions. At the same time, Tap integrates with systems such as ICP to achieve decentralized operations and enhance the practicality and security of Bitcoin for DeFi activities directly on the mainnet.
