Elastic Peripheral Base Contracts
Validate if the block timestamp has not reached the deadline yet, use for transactions with a deadline.
Reverts if the current block's timestamp is greater than the specified
deadline.Field | Type | Explanation |
|---|---|---|
deadline | uint256 | Timestamp to check against current block's timestamp |
Returns the current block timestamp. Used for overriding by mock contracts for tests.
Nonfungible tokens that support an approve via signature, i.e. permit for ERC721.
Immutable variables that are used by Periphery contracts.
Field | Type | Explanation |
|---|---|---|
factory | address | Factory contract address |
WETH | address | Canonical WETH address |
poolInitHash | bytes32 | keccak256 hash of the pool's creation code. Used to compute the pool address without reading storage from the Factory |
A helper contract to handle transfers, wrapping and unwrapping of tokens.
Unwraps the contract's entire WETH balance to ETH, then transfers them to the recipient.
Input Field | Type | Explanation |
|---|---|---|
minAmount | uint256 | Contract's WETH balance should not be lower than this amount |
recioient | address | Desired recipient of unwrapped ETH |
Transfers the contract's entire
token balance to the recipientInput Field | Type | Explanation |
|---|---|---|
token | address | Token to transfer |
minAmount | uint256 | Contract's token balance should not be lower than this amount |
recipient | address | Desired recipient of the token |
Transfers all ETH balance to the sender.
Internal function to help transfer tokens from the
sender to the recipient. If token is WETH and the contract has enough ETH balance, then wrap and transfer WETH, otherwise use RouterTokenHelper to handle transfers.Input Field | Type | Explanation |
|---|---|---|
token | address | Token to transfer |
sender | address | Address to pull token funds from |
recipient | address | Desired recipient of the token |
amount | uint256 | Amount to be transferred |
Unwraps the contract's entire WETH balance to ETH, then transfers them to the
recipient. Charges a fee which is transferred to feeRecipientInput Field | Type | Explanation |
|---|---|---|
minAmount | uint256 | Contract's WETH balance should not be lower than this amount |
recipient | address | Desired recipient of unwrapped ETH |
feeBps | uint256 | Fee to charge in basis points |
feeRecipient | address | Address to receive the fee charged |
Transfers the contract's entire
token balance to the recipient. Charges a fee which is transferred to feeRecipient.Input Field | Type | Explanation |
|---|---|---|
token | address | Token to transfer |
minAmount | uint256 | Contract's token balance should not be lower than this amount |
recipient | address | Desired recipient of the token |
feeBps | uint256 | Fee to charge in basis points |
feeRecipient | address | Address to receive the fee charged |
Enables calling multiple methods in a single call to the contract.
Uses
delegateCall to sequentially execute functions, then return the result of each execution.Field | Type | Explanation |
|---|---|---|
data | bytes[] | encoded function data for each of the calls to make to this contract |
Field | Type | Explanation |
|---|---|---|
results | bytes[] | results from each of the calls passed in |
A helper contract to handle liquidity related actions, including mint/add/remove liquidity.
Used when minting a new position or adding liquidity to an existing one.
Field | Type | Explanation |
|---|---|---|
token0 | address | first token of the pool |
token1 | address | second token of the pool |
fee | uint16 | the pool's swap fee |
tickLower | int24 | position's lower tick |
tickUpper | int24 | position's upper tick |
ticksPrevious | int24[2] | an array containing 2 values tickLowerPrevious and tickUpperPrevious which are expected to be the nearest initialized tick <= tickLower and tickUpper respectively |
amount0Desired | uint256 | token0 amount user wants to add |
amount1Desired | uint256 | token1 amount user wants to add |
amount0Min | uint256 | minimum token0 amount that should be used |
amount1Min | uint256 | minimum token1 amount that should be used |
Data for callback from Pool contract.
Field | Type | Explanation |
|---|---|---|
token0 | address | first token of the pool |
token1 | address | second token of the pool |
fee | uint16 | the pool's swap fee |
source | address | address to transfer token0/token1 from |
Mint callback function implementation called by a Pool.
Input Field | Type | Explanation |
|---|---|---|
deltaQty0 | uint256 | token0 amount requested by the pool |
deltaQty1 | uint256 | token1 amount requested by the pool |
data | bytes | Encoded CallbackData |
Add liquidity to a pool. token0 and token1 should be in the correct order, i.e token0 < token1.
Type | Explanation |
|---|---|
Parameters for addiing liquidity to a pool |
Field | Type | Explanation |
|---|---|---|
liquidity | uint128 | amount of liquidity added |
amount0 | uint256 | amount of token0 required |
amount1 | uint256 | amount of token1 required |
feeGrowthInsideLast | uint256 | latest feeGrowthInsideLast calculated by the pool |
pool | IProAMMPool | pool address |
Function to encode input parameters to CallbackData
Input Field | Type | Explanation |
|---|---|---|
token0 | address | first token of the pool |
token1 | address | second token of the pool |
fee | uint16 | the pool's swap fee |
Function for computing the pool address with the given input parameters.
Input Field | Type | Explanation |
|---|---|---|
token0 | address | first token of the pool |
