How Synapse Bridge Works
Understanding the step-by-step lock-and-mint and burn-and-release cycle of Synapse Bridge.
1. Initiating the Lock State
To initiate a transfer, the user connects their Web3 wallet to the interface and approves the token deposit. The smart contracts lock the designated tokens securely inside the vault state on the source network, publishing a public transaction receipt verified on the mempool explorer.
2. Verification and Relaying
Decentralized validators or secure relay nodes monitor the source network block logs. Once the transaction achieves block finality (checked against public explorers), the signatures are compiled to approve smart contract execution on the target chain.
3. Minting on the Target Chain
The target contract receives the cryptographic proof of deposit and mints the equivalent amount of tokens directly to the user's destination address. This completes the transfer cycle using advanced distributed ledger technology.
4. Redeeming and Burning
To return to the native asset, the user performs a burn transaction on the target layer. The contract destroys the wrapped tokens, signaling the source vault contract to unlock and release the native assets back to the user.
