Bridge Adapter

Bridge Adapter is a unified contract for interacting with bridges. It provides a single interface across routes and is used, for example, for crv emissions.

How to call

1. Call cost() to get the native gas fee to attach.
2. Call bridge(_token, _destination, _amount) as payable, passing the cost() result as msg.value.

Selectors: cost() -> 0x13faede6, bridge(address,address,uint256) -> 0x87121759
