Write Functions

bridgeERC721(_localToken: address, _remoteToken: address, _tokenId: uint256, _minGasLimit: uint32, _extraData: bytes) nonpayable

Initiates a bridge of an NFT to the caller's account on the other chain. Note that this function can only be called by EOAs. Smart contract wallets should use the `bridgeERC721To` function after ensuring that the recipient address on the remote chain exists. Also note that the current owner of the token on this chain must approve this contract to operate the NFT before it can be bridged. *WARNING**: Do not bridge an ERC721 that was originally deployed on Optimism. This bridge only supports ERC721s originally deployed on Ethereum. Users will need to wait for the one-week challenge period to elapse before their Optimism-native NFT can be refunded on L2.

Parameters

Name Type Description
_localToken address Address of the ERC721 on this domain.
_remoteToken address Address of the ERC721 on the remote domain.
_tokenId uint256 Token ID to bridge.
_minGasLimit uint32 Minimum gas limit for the bridge message on the other domain.
_extraData bytes Optional data to forward to the other chain. Data supplied here will not be used to execute any code on the other chain and is only emitted as extra data for the convenience of off-chain tooling.
bridgeERC721To(_localToken: address, _remoteToken: address, _to: address, _tokenId: uint256, _minGasLimit: uint32, _extraData: bytes) nonpayable

Initiates a bridge of an NFT to some recipient's account on the other chain. Note that the current owner of the token on this chain must approve this contract to operate the NFT before it can be bridged. *WARNING**: Do not bridge an ERC721 that was originally deployed on Optimism. This bridge only supports ERC721s originally deployed on Ethereum. Users will need to wait for the one-week challenge period to elapse before their Optimism-native NFT can be refunded on L2.

Parameters

Name Type Description
_localToken address Address of the ERC721 on this domain.
_remoteToken address Address of the ERC721 on the remote domain.
_to address Address to receive the token on the other domain.
_tokenId uint256 Token ID to bridge.
_minGasLimit uint32 Minimum gas limit for the bridge message on the other domain.
_extraData bytes Optional data to forward to the other chain. Data supplied here will not be used to execute any code on the other chain and is only emitted as extra data for the convenience of off-chain tooling.
finalizeBridgeERC721(_localToken: address, _remoteToken: address, _from: address, _to: address, _tokenId: uint256, _extraData: bytes) nonpayable

Completes an ERC721 bridge from the other domain and sends the ERC721 token to the recipient on this domain.

Parameters

Name Type Description
_localToken address Address of the ERC721 token on this domain.
_remoteToken address Address of the ERC721 token on the other domain.
_from address Address that triggered the bridge on the other domain.
_to address Address to receive the token on this domain.
_tokenId uint256 ID of the token being deposited.
_extraData bytes Optional data to forward to L1. Data supplied here will not be used to execute any code on L1 and is only emitted as extra data for the convenience of off-chain tooling.
initialize() nonpayable

Initializes the contract.
