Utils

This guide covers commonly used read methods for integration.

Factory-Level Lookups

Get Coin Bonding Curve Contract

function tokenToBondingCurve(address token) external view returns (address);

Get Coin Collateral Token

function tokenToCollateralToken(address token) external view returns (address);

• address(0) means native collateral.

• Non-zero means ERC20 collateral.

Check Migration Readiness

function readyForMigration(address token) external view returns (bool);

For stage boundaries in indexers and backend systems, use V2Migrated as the authoritative migration event.

Bonding Curve Reads

Use the token's bonding curve contract for curve-state reads.

Estimate Output with Fixed Input

function getAmountOutAndFee(
    uint256 _amountIn,
    uint256 _reserveIn,
    uint256 _reserveOut,
    bool _paymentTokenIsIn
) external view returns (uint256 amountOut, uint256 fee);

Estimate Input with Fixed Output

function getAmountInAndFee(
    uint256 _amountOut,
    uint256 _reserveIn,
    uint256 _reserveOut,
    bool _paymentTokenIsOut
) external view returns (uint256 amountIn, uint256 fee);

Curve Progress

function getCurveProgressBps() external view returns (uint256);

Curve Market Cap

function getMarketCap() external view returns (uint256);
