multicall(data: bytes[]) payable

Call multiple functions in the current contract and return the data from all of them if they all succeed

开发者： The `msg.value` should not be trusted for any method callable from multicall.

参数

名称 类型 描述
data bytes[] The encoded function data for each of the calls to make to this contract

返回值

名称 类型 描述
results bytes[] results The results from each of the calls passed in via data
refundETH() payable

Refunds any ETH balance held by this contract to the `msg.sender`

开发者： Useful for bundling with mint or increase liquidity that uses ether, or exact output swaps that use ether for the input amount
selfPermit(token: address, value: uint256, deadline: uint256, v: uint8, r: bytes32, s: bytes32) payable

Permits this contract to spend a given token from `msg.sender`

开发者： The `owner` is always msg.sender and the `spender` is always address(this).

参数

名称 类型 描述
token address The address of the token spent
value uint256 The amount that can be spent of token
deadline uint256 A timestamp, the current blocktime must be less than or equal to this timestamp
v uint8 Must produce valid secp256k1 signature from the holder along with `r` and `s`
r bytes32 Must produce valid secp256k1 signature from the holder along with `v` and `s`
s bytes32 Must produce valid secp256k1 signature from the holder along with `r` and `v`
selfPermitAllowed(token: address, nonce: uint256, expiry: uint256, v: uint8, r: bytes32, s: bytes32) payable

Permits this contract to spend the sender's tokens for permit signatures that have the `allowed` parameter

开发者： The `owner` is always msg.sender and the `spender` is always address(this)

参数

名称 类型 描述
token address The address of the token spent
nonce uint256 The current nonce of the owner
expiry uint256 The timestamp at which the permit is no longer valid
v uint8 Must produce valid secp256k1 signature from the holder along with `r` and `s`
r bytes32 Must produce valid secp256k1 signature from the holder along with `v` and `s`
s bytes32 Must produce valid secp256k1 signature from the holder along with `r` and `v`
selfPermitAllowedIfNecessary(token: address, nonce: uint256, expiry: uint256, v: uint8, r: bytes32, s: bytes32) payable

Permits this contract to spend the sender's tokens for permit signatures that have the `allowed` parameter

开发者： The `owner` is always msg.sender and the `spender` is always address(this) Can be used instead of #selfPermitAllowed to prevent calls from failing due to a frontrun of a call to #selfPermitAllowed.

参数

名称 类型 描述
token address The address of the token spent
nonce uint256 The current nonce of the owner
expiry uint256 The timestamp at which the permit is no longer valid
v uint8 Must produce valid secp256k1 signature from the holder along with `r` and `s`
r bytes32 Must produce valid secp256k1 signature from the holder along with `v` and `s`
s bytes32 Must produce valid secp256k1 signature from the holder along with `r` and `v`
selfPermitIfNecessary(token: address, value: uint256, deadline: uint256, v: uint8, r: bytes32, s: bytes32) payable

Permits this contract to spend a given token from `msg.sender`

开发者： The `owner` is always msg.sender and the `spender` is always address(this). Can be used instead of #selfPermit to prevent calls from failing due to a frontrun of a call to #selfPermit

参数

名称 类型 描述

recipient address The destination address of the token
sweepTokenWithFee(token: address, amountMinimum: uint256, recipient: address, feeBips: uint256, feeRecipient: address) payable

uniswapV3SwapCallback(amount0Delta: int256, amount1Delta: int256, _data: bytes) nonpayable

Called to `msg.sender` after executing a swap via IUniswapV3Pool#swap.

开发者： In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a UniswapV3Pool deployed by the canonical UniswapV3Factory. amount0Delta and amount1Delta can both be 0 if no tokens were swapped.

参数

名称 类型 描述
amount0Delta int256 The amount of token0 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token0 to the pool.
amount1Delta int256 The amount of token1 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token1 to the pool.
_data bytes
unwrapWETH9(amountMinimum: uint256, recipient: address) payable

Unwraps the contract's WETH9 balance and sends it to recipient as ETH.
