The Bitcoin ecosystem is experiencing notable advancements with various platforms and protocols enhancing Bitcoin-based decentralized finance (DeFi) and cross-chain interoperability. Braavos now allows users to move Bitcoin directly to its platform and earn native yield with a simple wallet integration. Babylon Genesis chain has integrated Bitcoin to support DeFi applications while maintaining Bitcoin's core principles of self-custody, trustlessness, and decentralization, with nearly 49,850 BTC valued at approximately $5.52 billion staked through Babylon Genesis. StakeCapital highlights that users can stake Bitcoin without wrapping or bridging it, preserving control while contributing to proof-of-stake network security. Chainlink has expanded its Cross-Chain Interoperability Protocol (CCIP) adoption to several platforms, including The Graph, Solv Protocol, and Mento Labs, enhancing the utility and accessibility of tokens like GRT across blockchains such as Arbitrum, Base, Solana, BNB Chain, and Ethereum. Solv Protocol also adopted Chainlink’s Cross-Chain Token standard for SolvBTC.Jup, supporting the scaling of Bitcoin finance (BTCFi). Chainlink further extended its services to opBNB, Rootstock, Solana, Bitlayer, TRON, and ZKsync, contributing to the growing infrastructure for seamless cross-chain DeFi. Additionally, BNB Chain promotes $BTCB, a bridged Bitcoin token combining Bitcoin’s security with BNB Smart Chain’s speed and flexibility, playing a crucial role in the BTCFi movement on its platform. Overall, these developments indicate increasing momentum toward making Bitcoin the foundational layer for trustless, interoperable finance across multiple blockchain ecosystems.
