Events

PairCreated

event PairCreated(address indexed token0, address indexed token1, address pair, uint);Copy

Emitted each time a pair is created via .

token0 is guaranteed to be strictly less than token1 by sort order.
The final uint log value will be 1 for the first pair created, 2 for the second, etc. (see /).

Read-Only Functions

getPair

function getPair(address tokenA, address tokenB) external view returns (address pair);Copy

Returns the address of the pair for tokenA and tokenB, if it has been created, else address(0) (0x0000000000000000000000000000000000000000).

tokenA and tokenB are interchangeable.

allPairs

function allPairs(uint) external view returns (address pair);Copy

Returns the address of the nth pair (0-indexed) created through the factory, or address(0) (0x0000000000000000000000000000000000000000) if not enough pairs have been created yet.

Pass 0 for the address of the first pair created, 1 for the second, etc.

allPairsLength

function allPairsLength() external view returns (uint);Copy

Returns the total number of pairs created through the factory so far.

feeTo

function feeTo() external view returns (address);Copy

See Protocol Charge Calculation.

feeToSetter

function feeToSetter() external view returns (address);Copy

State-Changing Functions

createPair

function createPair(address tokenA, address tokenB) external returns (address pair);Copy

Creates a pair for tokenA and tokenB if one doesn’t exist already.

tokenA and tokenB are interchangeable.
