In the multi-chain era, cross-chain bridges have long become a core component of blockchain infrastructure. However, most existing cross-chain solutions still rely on multi-signature or centralized custody mechanisms, posing potential trust risks and security vulnerabilities. Bitlayer's BitVM Bridge brings revolutionary breakthroughs to this field—being one of the earliest BitVM technology deployment projects on the mainnet, Bitlayer realizes truly trustless cross-chain through a Challenge-based Verification mechanism.

Industry-leading BitVM Bridge

The biggest highlight of the BitVM Bridge is that it uses Bitcoin as the final arbitration layer (Final Settlement Layer). All state transitions will ultimately be validated and confirmed on the Bitcoin network, providing 'Hard Finality.' This means that cross-chain assets no longer rely on third-party signers or custodial platforms, but are directly backed by the security of Bitcoin, truly achieving a 'Trust-Minimized' cross-chain design.

This structural innovation makes Bitlayer one of the few projects that can achieve a balance between cross-chain security and decentralization, and is thus regarded as an important pioneer and benchmark in the BitVM ecosystem.

Diverse Bridging Ecosystem: From PoS to Bitcoin Finality

Bitlayer's cross-chain design is not a single route, but rather a gradual progression:

  • Mainnet V1 (PoS): Collaborating with multiple MPC custodial platforms such as Coinbase and Sinohope to ensure asset security.

  • Mainnet V2 & V3 (Bitcoin Finality): Gradually introducing BitVM technology to provide truly trustless bridging, further enhancing security and transparency.

At the same time, Bitlayer is collaborating with Chainlink CCIP to build a trustless bridge between EVM chains, allowing users to instantly monitor cross-chain channel status through the CCIP Explorer.

Comprehensive Expansion: EVM, Public Chains, and CEX Interoperability

In addition to the Bitcoin mainchain and EVM ecosystem, Bitlayer is actively connecting more application scenarios:

  • Official Bridging: Supporting interoperability between Bitcoin and multiple public chains.

  • Third-party Bridging: Introducing more market-matured cross-chain solutions to expand liquidity.

  • CEX Bridging: Allowing users to directly withdraw from centralized exchanges to Bitlayer EVM wallet addresses, seamlessly entering the Layer 2 application environment.

This comprehensive bridging strategy positions Bitlayer as a 'core hub' in the multi-chain ecosystem, balancing user experience with a commitment to trustless technology.


Against the backdrop where many cross-chain solutions are still constrained by centralization risks, Bitlayer's BitVM Bridge, with its industry-leading technical route, has opened a new era of Bitcoin cross-chain. Its gradually evolving mainnet strategy, collaborations with top infrastructure providers, and comprehensive support for multi-chain and exchanges make Bitlayer not only the first BitVM mainnet implementer but also a potential bridge standard for the Bitcoin ecosystem and multi-chain world.
