Bridging Assets

The official LightLink bridge is now available at

When the user deposits ETH or other assets to the LightLink Bridge on Ethereum, Validator nodes confirm the deposit and notify the Keeper node. The Keeper node mints the same amount of ETH or other assets to the user’s address on LightLink.

To bridge assets from LightLink to Ethereum, the user first deposits them into the LightLink bridge on LightLink. Validator nodes confirm the deposit, and then the Keeper node burns or wraps those assets. Subsequently, the same amount of tokens is released from the bridge contract on Ethereum to the user’s address on Ethereum.

Please note that the bridging process from Ethereum to LightLink takes about 6 minutes for the transaction to finalize and become irreversible. This duration serves as a safety measure to prevent fraudulent activities on the bridge contract.

Please note that withdrawals from LightLink to Ethereum take two days due to security protocols.

This extended withdrawal timeframe is implemented to allow validators sufficient time to verify all transactions, ensuring they are valid and safe to proceed.
