Write Functions

bridgeERC20(_localToken: address, _remoteToken: address, _amount: uint256, _minGasLimit: uint32, _extraData: bytes) nonpayable

Sends ERC20 tokens to the sender's address on the other chain. Note that if the ERC20 token on the other chain does not recognize the local token as the correct pair token, the ERC20 bridge will fail and the tokens will be returned to sender on this chain.

Parameters

Name Type Description
_localToken address Address of the ERC20 on this chain.
_remoteToken address Address of the corresponding token on the remote chain.
_amount uint256 Amount of local tokens to deposit.
_minGasLimit uint32 Minimum amount of gas that the bridge can be relayed with.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
bridgeERC20To(_localToken: address, _remoteToken: address, _to: address, _amount: uint256, _minGasLimit: uint32, _extraData: bytes) nonpayable

Sends ERC20 tokens to a receiver's address on the other chain. Note that if the ERC20 token on the other chain does not recognize the local token as the correct pair token, the ERC20 bridge will fail and the tokens will be returned to sender on this chain.

Parameters

Name Type Description
_localToken address Address of the ERC20 on this chain.
_remoteToken address Address of the corresponding token on the remote chain.
_to address Address of the receiver.
_amount uint256 Amount of local tokens to deposit.
_minGasLimit uint32 Minimum amount of gas that the bridge can be relayed with.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
bridgeETH(_minGasLimit: uint32, _extraData: bytes) payable

Sends ETH to the sender's address on the other chain.

Parameters

Name Type Description
_minGasLimit uint32 Minimum amount of gas that the bridge can be relayed with.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
bridgeETHTo(_to: address, _minGasLimit: uint32, _extraData: bytes) payable

Sends ETH to a receiver's address on the other chain. Note that if ETH is sent to a smart contract and the call fails, the ETH will be temporarily locked in the StandardBridge on the other chain until the call is replayed. If the call cannot be replayed with any amount of gas (call always reverts), then the ETH will be permanently locked in the StandardBridge on the other chain. ETH will also be locked if the receiver is the other bridge, because finalizeBridgeETH will revert in that case.

Parameters

Name Type Description
_to address Address of the receiver.
_minGasLimit uint32 Minimum amount of gas that the bridge can be relayed with.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
finalizeBridgeERC20(_localToken: address, _remoteToken: address, _from: address, _to: address, _amount: uint256, _extraData: bytes) nonpayable

Finalizes an ERC20 bridge on this chain. Can only be triggered by the other StandardBridge contract on the remote chain.

Parameters

Name Type Description
_localToken address Address of the ERC20 on this chain.
_remoteToken address Address of the corresponding token on the remote chain.
_from address Address of the sender.
_to address Address of the receiver.
_amount uint256 Amount of the ERC20 being bridged.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
finalizeBridgeETH(_from: address, _to: address, _amount: uint256, _extraData: bytes) payable

Finalizes an ETH bridge on this chain. Can only be triggered by the other StandardBridge contract on the remote chain.

Parameters

Name Type Description
_from address Address of the sender.
_to address Address of the receiver.
_amount uint256 Amount of ETH being bridged.
_extraData bytes Extra data to be sent with the transaction. Note that the recipient will not be triggered with this data, but it will be emitted and can be used to identify the transaction.
finalizeBridgeETHDirect(_from: address, _to: address, _amount: uint256, _extraData: bytes) payable

See { StandardBridge-finalizeBridgeETH }

Parameters

Name Type Description
_from address
_to address
_amount uint256
_extraData bytes
initialize() nonpayable
