The Chainlink Standard Is Now Live on Bitlayer As Its Canonical Cross-Chain Infrastructure

We’re excited to announce that the Chainlink standard is now live on Bitlayer. Chainlink Cross-Chain Interoperability Protocol (CCIP)serves as Bitlayer’s canonical cross-chain infrastructure, enabling Bitlayer developers to build secure cross-chain applications that drive BTCFi adoption.

“It’s great to see that the Chainlink standard is now live on Bitlayer, whose efforts to ensure Bitcoin-equivalent security and next-level scalability act as a positive force for the greater BTCFi ecosystem. Using Chainlink CCIP, developers in the Bitlayer ecosystem can now build secure, novel cross-chain applications that support the growth of BTCFi.”—Johann Eid, Chief Business Officer at Chainlink Labs.

We selected CCIP as our canonical interoperability solution due to Chainlink’s proven track record of maintaining phenomenal standards of security and reliability in the blockchain industryCCIP remains the only interoperability solution achieving level-5 cross-chain security. Thanks to its principle-driven approach, Chainlink has built one of the largest ecosystems in the blockchain industry and is the blockchain connectivity standard within capital markets.

With the rapidly increasing awareness and adoption of DeFi on Bitcoin (BTCFi), Bitlayer is positioned to help unlock new use cases and scale Bitcoin to hundreds of millions of users.

Chainlink CCIP provides a multitude of important benefits and features, such as:

• Battle Tested security—CCIP’s consensus layer is powered by Chainlink Decentralized Oracle Networks (DONs), infrastructure that has secured over $75 billion in DeFi TVL at its peak and enabled over $18 trillion in onchain transaction value since the start of 2022.

• Secure Token Transfers—Cross-Chain Tokens (CCTs) are token logic agnostic, meaning token developers can deploy pre-audited token pool contracts to turn any ERC20-compatible token into a CCT or deploy their own custom token pool contracts for bespoke token use cases. CCTs do not require token developers to inherit any CCIP-specific code within their token’s smart contract. CCTs also benefit from additional security functions in their CCIP token pools, such as configurable rate limits and reliability features such as Smart Execution, which helps ensure reliable transaction execution on the destination chain regardless of blockchain network congestion.

• Arbitrary Messaging—CCIP empowers developers to create cross-chain native applications through the transfer of arbitrary data, encoded as bytes, between smart contracts on different blockchains. Cross-chain messaging enables numerous use cases from cross-chain NFT transfers to cross-chain lending.

• Programmable Token Transfers—CCIP enables the transfer of value (via CCTs) cross-chain along with data instructions informing the receiving smart contract on what to do with those tokens once they arrive on the destination chain. Through Programmable Token Transfers, CCIP can condense a complex set of actions involving multiple users, blockchains, and assets down to a single atomic cross-chain instruction.

• Extendable and future-proof—CCIP is built to be future-proof for developers, where future improvements can continue to be made, including the integration of new blockchain networks, the permissionless onboarding of additional tokens by developers while retaining full ownership of their token contracts, and the incorporation of new battle tested approaches to security.

“We’re thrilled that the Chainlink standard is live on Bitlayer, our key cross-chain infrastructure. Chainlink CCIP enables Bitlayer developers to build secure, feature-rich cross-chain applications that expand the BTCFi economy.” — Charlie Hu, co-founder at Bitlayer.
