Factory

Events
PairCreated
event PairCreated(address indexed token0, address indexed token1, bool stable, address pair, uint);
Emitted each time a pair is created via createPair.
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 allPairs/getPair).
Read-Only Functions
getPair
function getPair(address tokenA, address tokenB, bool stable) external view returns (address pair);
Returns the address of the pair for tokenA and tokenB with the pool type if it has been created, else address(0) (0x0000000000000000000000000000000000000000).
tokenA and tokenB are interchangeable.
Pair addresses can also be calculated deterministically via the SDK.
allPairs
function allPairs(uint) external view returns (address pair);
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);
Returns the total number of pairs created through the factory so far.
State-Changing Functions
createPair
function createPair(address tokenA, address tokenB, bool stable) external returns (address pair);
Creates a pair of the specified type for tokenA and tokenB if one doesn't exist already.
tokenA and tokenB are interchangeable.
Emits PairCreated.
