Notes

Socket is a bridge aggregator — routes through underlying bridges (Across, Stargate, Hop, cBridge, Connext, etc.)
Two-step process: (1) call Socket API to get a route + encoded bridgeData, (2) execute on-chain via executeRoute()
There is no separate bridge() entry point: executeRoute() handles bridge, swap, and combined routes
Same Gateway address (0x3a23F9...) deployed across all supported chains
routeId identifies the specific bridge integration (each bridge has its own route handler contract)
The bridgeData is opaque — generated by the Socket API based on token, amount, source/destination chains
Requires ERC-20 approval to the Socket Gateway address
Finality depends on the underlying bridge selected

On Ethereum, Socket is a namespace: its contracts need no import.

function main() {
  // Ethereum's socketGateway, `0x3a23F943181408EAC424116Af7b7790c94Cb97a5`.
  require(Socket.SocketGateway != 0);
}
