FeeAmount.LOW: 0.15% = LP fee 0.05% + protocol fee 0.05%

FeeAmount.MEDIUM: 0.35% = LP fee 0.3% + protocol fee 0.05%

FeeAmount.HIGH: 1.05% = LP fee 1% + protocol fee 0.05%

Sample pool setup

const reactorPoolContractId = '0xa5843e9c21e5039d527b25b45c8f3c28ca33258ae52e6350764024ef24831966'
const usdcAssetId = '0x0e992cf93b0608b91810c8019b1efec87581e27c26f85a356ffe7b307c5a8611'
const btcAssetId = '0x410722449f15d387bbce10a0989bf349aee17090e97785d23da524997c0bc6c0'
const fee = FeeAmount.MEDIUM

Quote exact in

Returns "amountOut" for specified "amountIn"

let amountOut = await quoteExactIn(
    reactorPoolContractId,
    wallet,
    [usdcAssetId, // pool's token0 asset id
        btcAssetId, // pool's token1 asset id
        fee // pool's fee tier
    ],
    btcAssetId, // input token
    usdcAssetId, // output token
    '100000', // input amount
);

Swap exact in

let txResult = await swapExactIn(
    reactorPoolContractId,
    wallet,
    [usdcAssetId, // pool's token0 asset id
        btcAssetId, // pool's token1 asset id
        fee // pool's fee tier
    ],
    btcAssetId, // input token
    usdcAssetId, // output token
    '100000', // input amount
);

Quote exact out

Returns "amountIn" for specified "amountOut"

let amountIn = quoteExactOut(
    reactorPoolContractId,
    wallet,
    [usdcAssetId, // pool's token0 asset id
        btcAssetId, // pool's token1 asset id
        fee // pool's fee tier
    ],
    btcAssetId, // input token
    usdcAssetId, // output token
    '100000', // output amount
)

Swap exact out

let txResult = await swapExactOut(
    reactorPoolContractId,
    wallet,
    [usdcAssetId, // pool's token0 asset id
        btcAssetId, // pool's token1 asset id
        fee // pool's fee tier
    ],
    btcAssetId, // input token
    usdcAssetId, // output token
    '100000', // output amount
)
