Usage
👷🏽♀️ Building the SDK
import { buildSdk } from "@balmy/sdk";
const sdk = buildSdk(config);
⚖️ Getting balance for multiple tokens on several chains
const accountBalances = await sdk.balanceService.getBalancesForTokens({
account: "0x000000000000000000000000000000000000dead",
tokens: {
// [chainId]: [0xTokenAddress]
[Chains.ETHEREUM.chainId]: [
// Ethereum
"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", // USDC
"0x6b175474e89094c44da98b954eedeac495271d0f", // DAI
],
[Chains.OPTIMISM.chainId]: [
// Optimism
"0x7f5c764cbc14f9669b88837ca1490cca17c31607", // USDC
"0xda10009cbd5d07dd0cecc66161fc93d7c9000da1", // DAI
],
},
// Optional config
config: {
timeout: "30s",
},
});
const usdcBalanceOnEthereum =
accountBalances[Chains.ETHEREUM.chainId][
"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"
];
💸 Getting allowances of multiple spenders for a token
const accountAllowances = await sdk.allowanceService.getAllowances({
chainId: Chains.ETHEREUM.chainId,
token: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", // USDC
owner: "0x000000000000000000000000000000000000dead",
spenders: ["0x6666666600000000000000000000000000009999"],
});
const amountThatDevilCanSpend =
accountAllowances["0x6666666600000000000000000000000000009999"];
🔄 Quoting all dex aggregators for a trade
const allQuotes = await sdk.quoteService.getAllQuotesWithTxs({
request: {
chainId: Chains.ETHEREUM.chainId, // Ethereum
sellToken: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
buyToken: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",
order: {
type: "sell",
sellAmount: utils.parseUnits("1000", 6), // 1000 USDC
},
slippagePercentage: 1, // 1%
takerAddress: signer.address,
// Optional gas speed
gasSpeed: {
speed: "instant",
},
},
// Optional config
config: {
sort: {
by: "most-swapped-accounting-for-gas",
},
},
});
const bestTradeBySort = allQuotes[0];
await signer.sendTransaction(bestTradeBySort.tx);
