寫入函式

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.

參數

名稱 類型 描述
_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.

參數

名稱 類型 描述
_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.

參數

名稱 類型 描述
_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.

參數

名稱 類型 描述
_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.

參數

名稱 類型 描述
_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.

參數

名稱 類型 描述
_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.
finalizeDeposit(_l1Token: address, _l2Token: address, _from: address, _to: address, _amount: uint256, _extraData: bytes) payable

Finalizes a deposit from L1 to L2. To finalize a deposit of ether, use address(0) and the l1Token and the Legacy ERC20 ether predeploy address as the l2Token.

參數

名稱 類型 描述
_l1Token address Address of the L1 token to deposit.
_l2Token address Address of the corresponding L2 token.
_from address Address of the depositor.
_to address Address of the recipient.
_amount uint256 Amount of the tokens being deposited.
_extraData bytes Extra data attached to the deposit.
initialize() nonpayable

Initializer

withdraw(_l2Token: address, _amount: uint256, _minGasLimit: uint32, _extraData: bytes) payable

Initiates a withdrawal from L2 to L1. This function only works with OptimismMintableERC20 tokens or ether. Use the `bridgeERC20` function to bridge native L2 tokens to L1.

參數

名稱 類型 描述
_l2Token address Address of the L2 token to withdraw.
_amount uint256 Amount of the L2 token to withdraw.
_minGasLimit uint32 Minimum gas limit to use for the transaction.
_extraData bytes Extra data attached to the withdrawal.
withdrawTo(_l2Token: address, _to: address, _amount: uint256, _minGasLimit: uint32, _extraData: bytes) payable

Initiates a withdrawal from L2 to L1 to a target account on L1. Note that if ETH is sent to a contract on L1 and the call fails, then that ETH will be locked in the L1StandardBridge. ETH may be recoverable if the call can be successfully replayed by increasing the amount of gas supplied to the call. If the call will fail for any amount of gas, then the ETH will be locked permanently. This function only works with OptimismMintableERC20 tokens or ether. Use the `bridgeERC20To` function to bridge native L2 tokens to L1.

參數

名稱 類型 描述
_l2Token address Address of the L2 token to withdraw.
_to address Recipient account on L1.
_amount uint256 Amount of the L2 token to withdraw.
_minGasLimit uint32 Minimum gas limit to use for the transaction.
_extraData bytes Extra data attached to the withdrawal.
