deBridge

This contract is the main point of cross-chain interactions coming from users and protocols. It enables sending and execution of cross-chain messages

DeBridgeGate

This contract is the main point of cross-chain interactions coming from users and protocols. Its "send" method enables sending arbitrary messages and assets cross-chain in one transaction

DeBridgeToken

ERC20 token that is used as a wrapped asset (deAsset). Protocol guarantees that all deAssets are 1:1 backed by the collateral locked in DeBridgeGate smart contract on the source chain

DeBridgeTokenDeployer

DeBridgeTokenDeployer is a deAsset deployment factory

SignatureVerifier

This smart contract verifies the validity of all validators' signatures to execute the sent transaction on the destination chain in case at least 2/3 of the signatures are valid.

CallProxy

CallProxy smart contract to execute the external call with a transferred message to the receiving smart contract.

WethGate

Upgradable contracts cannot receive ETH via transfer because of increased SLOAD gas cost. This non-upgradeable smart contract is used as the proxy-recipient to immediately transfer funds to the upgradable contract to bypass the "out of gas" problem.
