CapswapV2Factory.sol

Address

CapswapV2Factory is deployed at 0x33CB4150f3ADFCD92fbFA3309823A2a242bF280f on the Cube mainnet.

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);

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.

Events

Mint

event Mint(address indexed sender, uint amount0, uint amount1);

Emitted each time liquidity tokens are created via mint.

Burn

event Burn(address indexed sender, uint amount0, uint amount1, address indexed to);

Emitted each time liquidity tokens are destroyed via burn.

Swap

event Swap(
  address indexed sender,
  uint amount0In,
  uint amount1In,
  uint amount0Out,
  uint amount1Out,
  address indexed to
);

Emitted each time a swap occurs via swap.

Sync

event Sync(uint112 reserve0, uint112 reserve1);

Emitted each time reserves are updated via mint, burn, swap, or sync.

State-Changing Functions

mint

function mint(address to) external returns (uint liquidity);

Creates pool tokens.

  • Emits Mint, Sync, Transfer.

burn

function burn(address to) external returns (uint amount0, uint amount1);

Destroys pool tokens.

  • Emits Burn, Sync, Transfer.

swap

function swap(uint amount0Out, uint amount1Out, address to, bytes calldata data) external;

Swaps tokens. For regular swaps, data.length must be 0. Also see Flash Swaps.

  • Emits Swap, Sync.

skim

function skim(address to) external;

sync

function sync() external;
