Curve JS

Setup

Install from npm:

npm install @curvefi/api

Init

import curve from "@curvefi/api";

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

    // 2. Infura
    await curve.init("Infura", { network: "homestead", apiKey: <INFURA_KEY> }, { chainId: 1 });
    
    // 3. Web3 provider
    await curve.init('Web3', { externalProvider: <WEB3_PROVIDER> }, { chainId: 1 });
    
    // Fetch factory pools
    await curve.factory.fetchPools();
    await curve.crvUSDFactory.fetchPools();
    await curve.EYWAFactory.fetchPools();
    await curve.cryptoFactory.fetchPools();
    await curve.twocryptoFactory.fetchPools();
    await curve.tricryptoFactory.fetchPools();
    await curve.stableNgFactory.fetchPools(); 
})()

Note 1. chainId parameter is optional, but you must specify it in the case you use Metamask on localhost network, because Metamask has that bug

Note 2. Web3 init requires the address. Therefore, it can be initialized only after receiving the address.

Wrong ❌️

Notes

  • 1 Amounts can be passed in args either as numbers or strings.
  • 2 depositOrWithdrawBonus and swapPriceImpact methods return %, e. g. 0 < bonus/priceImpact <= 100
  • 3 Slippage arg should be passed as %, e. g. 0 < slippage <= 100

Gas estimation

Every non-constant method has corresponding gas estimation method. Rule: obj.method -> obj.estimateGas.method

Examples

import curve from "@curvefi/api";

(async () => {
    await curve.init('JsonRpc', {}, { gasPrice: 0, maxFeePerGas: 0, maxPriorityFeePerGas: 0 });
    
    const spender = "0xbEbc44782C7dB0a1A60Cb6fe97d0b483032FF1C7" // 3pool swap address
    await curve.estimateGas.ensureAllowance(["DAI", "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"], [1000, 1000], spender);
    // 94523
    
    const pool = curve.getPool('usdn');
    await pool.estimateGas.depositApprove(["1000", "1000", "1000", "1000"]);
    // 186042
    await pool.estimateGas.deposit(["1000", "1000", "1000", "1000"]);
    // 679238
    
    await curve.router.estimateGas.swap('DAI', "WBTC", "1000");
    // 476904
    await curve.boosting.estimateGas.createLock('1000', 365);
    // 324953
})()

Gas estimation L2

Only for OPTIMISM and BASE!

Arbitrium is also L2 network, but for estimateGas should use default method estimateGas, which return Number.

For L2 networks estimateGas return array [L2GasUsed, L1GasUsed], where L2GasUsed - gas estimate for execution transaction in current L2 network, and L1GasUsed - gas estimate for data storage in parent L1 network.

Gas Price in L1 is required to calculate the fee. You can use getGasPriceFromL1 for get Gas Price in L1.

 const L1GasPrice = await curve.getGasPriceFromL1()
 // 23348207475

Calculate fee fee = L2GasUsed*L2GasPrice + L1GasUsed*L1GasPrice

For OP and Base networks you can get L2GasPrice from curve.getGasPriceFromL2

 const L2GasPrice = await curve.getGasPriceFromL2()
 // 13161051
