# Cross-chain Bridge

## Cross-Chain Mechanics

SolvBTC’s cross-chain functionality is powered by **Chainlink’s Cross-Chain Interoperability Protocol (CCIP)** and **Free.tech**, enabling secure and efficient transactions between different blockchains. This ensures that users can move their SolvBTC tokens between chains seamlessly, without incurring high transaction costs or experiencing delays. The combination of these technologies allows Solv Protocol to provide a frictionless experience for users who want to maximize their Bitcoin’s liquidity across ecosystems.

Note: a $5 bridging fee will be charged for CCIP transactions.
