Registry Smart Contract Code and ABI

Registry

Verified

Verified, Router
Router

The following smart contract is a Registry contract that manages routes for cross-chain transfers. It allows adding, disabling, and executing routes for middleware and bridge contracts. It also includes a function for rescuing funds and uses OpenZeppelin libraries for access control and ERC20 token handling.
