Lock and Mint Mechanism

The lock and mint mechanism is a fundamental method used by bridges to enable cross-chain asset transfers. In this process, a user sends assets to a smart contract on the source chain, where they are securely locked in a vault.

Once the contract confirms the lock, a corresponding amount of synthetic or wrapped tokens is minted on the destination chain. This ensures that the total supply of the bridged asset remains pegged to the collateral held on the source chain.

The process is reversed when a user wants to redeem their original assets, involving the burning of the synthetic tokens. This mechanism relies entirely on the smart contract's ability to maintain the lock and accurately trigger the minting process.

If the locked collateral is compromised, the synthetic assets on the destination chain lose their backing and value. It is a common design pattern for moving tokens like Bitcoin or Ethereum across different ecosystems.

Security depends on the robustness of the vault contract and the validator set managing the bridge.
