Transfer Gateways and Ronin Bridge

Transfer Gateway

Transfer Gateway is the gate for token transfer onto the sidechain and the subsequent transfer back to Ethereum. At the moment we support our users depositing on ETH, ERC20, and ERC721.

Transfer Gateway contracts include:

  • MainchainGateway contract deployed on the Ethereum chain.
  • SidechainGateway contract deployed on the Ronin chain.

Whenever users deposit or withdraw their assets these contracts will emit corresponding events.

Ronin Bridge

Ronin Bridge is actually a service to track events from the MainchainGateway and SidechainGateway contracts. Each validator has to run the Bridge so that this service can be acknowledged for the validator.
