交换（Exchange）

这是一个扩展Jetton的智能合约，它是用每个流动性对创建的。 路由器在请求创建新池时部署它。尽管路由器实际上存储了一对中的两个代币并通过它进行交换，但必须调用交换合约才能提供或获取流动性。

How to build transaction

• Add Liquidity

// 1. add liquidity tokenA
await sendInternalMessageWithWallet({
    walletContract,
    secretKey,
    to: userJettonAWalletAddress,
    value: toNano(0.7),
    body: beginCell()
        .storeUint(0xf8a7ea5, 32)
        .storeUint(query_id, 64)
        .storeCoins(jettonAAmount)
        .storeAddress(lpAddress)
        .storeAddress(responseAddress)
        .storeDict(beginCell().endCell())
        .storeCoins(toNano(0.5))
        .storeDict(beginCell()
            .storeCoins(minAmountForJettonA)
            .storeCoins(minAmountForJettonB)
        .endCell())
    .endCell()
});

// 2. add liquidity tokenB
await sendInternalMessageWithWallet({
    walletContract,
    secretKey,
    to: userJettonBWalletAddress,
    value: toNano(0.7),
    body: beginCell()
        .storeUint(0xf8a7ea5, 32)
        .storeUint(query_id, 64)
        .storeCoins(jettonBAmount)
        .storeAddress(lpAddress)
        .storeAddress(responseAddress)
        .storeDict(beginCell().endCell())
        .storeCoins(toNano(0.5))
        .storeDict(beginCell()
            .storeCoins(minAmountForJettonA)
            .storeCoins(minAmountForJettonB)
        .endCell())
    .endCell()
});

• Remove Liquidity

await sendInternalMessageWithWallet({
    walletContract,
    secretKey,
    to: lpAddress,
    value: toNano(0.35),
    body: beginCell()
        .storeUint(0x595f07bc, 32)
        .storeUint(query_id, 64)
        .storeCoins(lpAmount)
        .storeDict(beginCell()
            .storeCoins(minAmountForJettonA)
            .storeCoins(minAmountForJettonB)
        .endCell())
    .endCell()
});

• Claim

await sendInternalMessageWithWallet({
    walletContract,
    secretKey,
    to: lpAddress,
    value: toNano(0.15),
    body: beginCell()
        .storeUint(0x6b14cfe1, 32)
        .storeUint(query_id, 64)
    .endCell()
});
