Get FewToken Address via FewFactory

Ring Swap uses wrapped tokens (FewTokens) in pools and swap paths.

When you quote prices or build routes, use FewToken addresses instead of original ERC20 token addresses.

FewFactory Interface

interface IFewFactory {
    function getWrappedToken(address originalToken) external view returns (address wrappedToken);
}

Example Helper Contract

pragma solidity ^0.8.26;

interface IFewFactory {
    function getWrappedToken(address originalToken) external view returns (address);
}

contract FewTokenHelper {
    address public fewFactory;

    constructor(address _fewFactory) {
        fewFactory = _fewFactory;
    }

    function getFewTokenAddress(address originalToken) external view returns (address wrappedToken) {
        return IFewFactory(fewFactory).getWrappedToken(originalToken);
    }
}

Building a Swap Path

For a logical route:

tokenA -> USDC -> tokenB

Resolve wrapped tokens first:

fwTokenA = FewFactory.getWrappedToken(tokenA)
fwUSDC = FewFactory.getWrappedToken(USDC)
fwTokenB = FewFactory.getWrappedToken(tokenB)

Then pass:

path = [fwTokenA, fwUSDC, fwTokenB]
