设置

从 npm 安装 :

npm install @curvefi/llamalend-api

输入

import llamalend from "@curvefi/llamalend-api";

(async () => {
    // 1. Dev
    await llamalend.init('JsonRpc', {url: 'http://localhost:8545/', privateKey: ''}, { gasPrice: 0, maxFeePerGas: 0, maxPriorityFeePerGas: 0, chainId: 1 });
    // OR
    await llamalend.init('JsonRpc', {}, {}); // In this case JsonRpc url, privateKey, fee data and chainId will be specified automatically

    // 2. Infura
    llamalend.init("Infura", { network: "homestead", apiKey: <INFURA_KEY> }, { chainId: 1 });
    
    // 3. Web3 provider
    llamalend.init('Web3', { externalProvider: <WEB3_PROVIDER> }, { chainId: 1 });
})()

说明1. chainId 参数是可选的,但在本地主机网络上使用Metamask时必须指定,因为Metamask有此功能 错误

说明2. Web3 init需要地址. 因此,只有在收到地址后才能初始化.

强制更新出借的用户状态

执行某些交易后,建议强制更新缓存中的用户状态,以确保数据一致性:

// Methods after which you should call forceUpdateUserState:
// - createLoan()
// - leverage.createLoan()
// - borrowMore()
// - partialSelfLiquidate()
// - repay()

// Basic usage (after successful transaction):
const txHash = await lendMarket.createLoan(0.5, 1000, 5);
// Wait for transaction to be mined and confirmed
await lendMarket.forceUpdateUserState(txHash);

// With specific user address:
await lendMarket.forceUpdateUserState(txHash, "0x123...");

// The method sends a request with new_tx parameter and clears the cache
// to get fresh user state data
// Important: Only call after successful transaction confirmation

为什么使用强制 Update UserState?

• 确保成功交易后的数据一致性
• 清除缓存的用户状态数据
• 将新 API 请求与交易散列
• 防止陈旧的数据问题
• 重要: 仅在交易成功被布雷和确认后才呼叫

何时使用 :

• 之后 createLoan() - 创建新贷款时
• 之后 leverage.createLoan() - 在创建杠杆位置时
• 之后 borrowMore() - 增加贷款额时
• 之后 partialSelfLiquidate() - 部分清理位置时
• 之后 repay() - 偿还贷款时

借出( 创建 Loan, 借出 More, 偿还) 借出 Market 杠杆 ZapV2

LendMarket杠杆操作支持不同的路由器,并需要外部路由服务提供的引用信息.

中断更改

1. 新的衡量标准方法 -- -- 将所有衡量标准纳入一个呼叫中

• 改为 createLoanBands, (中文(简体) ), createLoanPrices, (中文(简体) ), createLoanHealth, (中文(简体) ), createLoanPriceImpact数字 : createLoanExpectedMetrics() - 价格、波段、价格、健康
• 改为 borrowMoreBands, (中文(简体) ), borrowMorePrices, (中文(简体) ), borrowMoreHealth, (中文(简体) ), borrowMorePriceImpact数字 : borrowMoreExpectedMetrics() - 回报价格影响、波段、价格、健康
• 改为 repayBands, (中文(简体) ), repayPrices, (中文(简体) ), repayHealth, (中文(简体) ), repayPriceImpact数字 : repayExpectedMetrics() - 回报价格影响、波段、价格、健康

Iverage 度量衡 - 用新方法返回的计量对象:

interface ILeverageMetrics {
    priceImpact: number;
    bands: [number, number];
    prices: string[];
    health: string;
}

2. 最后方法现在需要 router, (中文(简体) ), calldata 财务报告和审定财务报表 minRecv 参数

• 在此之前数字 : createLoan(userCollateral, userBorrowed, debt, range)
• 现在数字 : createLoan(userCollateral, userBorrowed, debt, range, minRecv, router, calldata)
• 在此之前数字 : borrowMore(userCollateral, userBorrowed, debt, slippage)
• 现在数字 : borrowMore(userCollateral, userBorrowed, debt, minRecv, router, calldata)
• 在此之前数字 : repay(stateCollateral, userCollateral, userBorrowed, slippage)
• 现在数字 : repay(stateCollateral, userCollateral, userBorrowed, minRecv, router, calldata)

地点 router - 路由器地址, calldata - 调用数据字节代码, minRecv - 最低接收额(见 安全改进(中文(简体) )

理解召回函数和引用

获取预期Fn - 从路由器取出引号的调用函数(例如Odos, Curve):

type GetExpectedFn = (
    fromToken: string,      // Address of token to swap from
    toToken: string,        // Address of token to swap to
    amountIn: bigint,       // Amount of tokens to swap (in wei)
    blacklist: string | string[], // Contract/pool addresses to exclude
) => Promise<IQuote | null>; // null when no route is found

引用 - 有互换信息的引用对象:

interface IQuote {
    outAmount: string;      // Amount of tokens to receive
    priceImpact: number;    // Price impac
}

不同操作需要引用哪些词

为创建Loan和借更多:

• 换取引用 (debt + userBorrowed) 借入的代币 − 抵押代币
• 示例:债务=2000,用户Borrowed=1000, 借出3000个借入的令牌换作抵押

快点! 注意:这里的债务是指操作期间所增加的债务金额,而不是用户在操作后将拥有的新的债务总额.

偿还:

• 换取引用 (stateCollateral + userCollateral) 有价证券 = 借出证券
• 示例: 对于 State Corlateral = 2 和 user Corlateral = 1 , 以 3 个抵押符交换出所借符

安全改进

执行方法(createLoan, (中文(简体) ), borrowMore, (中文(简体) ), repay接受一个 minRecv 参数保证了交换后收到的最低信使数量。 这可以保护用户避免滑行和前跑.

使用 calcMinRecv(expected, slippage) 计算最低可接受数量:

公式 : minRecv = expected * (100 - slippage) / 100

• expected ——从互换中预期的代币金额
• slippage ——允许下降百分比(如:. 0.5 (0.5%)

// quote.outAmount — the expected amount from your router (computed on your side)
const minRecv = lendMarket.leverageZapV2.calcMinRecv(quote.outAmount, 0.5); // 0.5% slippage
await lendMarket.leverageZapV2.createLoan({ userCollateral, debt, range, minRecv, router, calldata });
