A few days ago, the DeFi protocol @ Brotocol-xyz of the BTC ecosystem was officially released. This name is a combination of the words Bitcoin and Protocol. One sentence to understand what Brotocol wants to do: buy everything with BTC. One important aspect of Brotocol's product values is to encourage users to manage BTC and stablecoins through a single Bitcoin wallet and participate in DeFi applications. This requires positioning BTC as a DeFi core asset and connecting global liquidity through native cross chain solutions, without relying on public chain architectures such as Ethereum/Solana. Specifically, Brotocol includes these three modules: 1/BroBridge (Cross Chain Bridge): Supports users to transfer stablecoins (such as USDC) on the chain, such as Arbitrum and Solana, across chains into the Bitcoin network, and can pledge assets through the Babylon protocol to maintain Bitcoin as the underlying financial account attribute. 2/BroSwap (full chain DEX open beta): Allow users to directly exchange tokens within Bitcoin wallets (such as the Xverse), supporting asset swaps between BTC and USDT, SOL, ETH, meme coins, etc., without the need to manage multi chain wallets. 3/BroPay (Payment): Non Bitcoin users can use ETH, SOL, or USDT to pay merchants, and the backend automatically converts to native BTC settlement to lower the threshold for using the Bitcoin ecosystem. ​ Brotocol plans to collaborate with multi chain projects to build a unified ecosystem. Currently, it has partnered with Joltz to integrate USDT and Taproot assets, connecting the Bitcoin Lightning Network, Liquid sidechains, and DeFi protocols. The USDT that Tether will issue on Taproot Assets in the future will also bring greater liquidity to Brother's product system. Brotocol's long-term goal is to provide a seamless Bitcoin financial infrastructure for developers, users, and merchants.
