Address

ReefswapV2Factory is deployed at 0x380a9033500154872813F6E1120a81ed6c0760a8 on the Reef mainnet, and at 0x9b9a32c56c8F5C131000Acb420734882Cc601d39 on the Reef testnet.

Events

PairCreated

event PairCreated(address indexed token0, address indexed token1, 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) external view returns (address pair);

Returns the address of the pair for tokenA and tokenB, 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.

feeTo

function feeTo() external view returns (address);

See Protocol Charge Calculation.

feeToSetter

function feeToSetter() external view returns (address);

The address allowed to change feeTo.

State-Changing Functions

createPair

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

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

• tokenA and tokenB are interchangeable.

• Emits PairCreated.
