This npm package exports the class: MarketDataReaderFactory, the class: MarketTransManagerFactory, and the object: CHAINS that are essential for interacting with the smart contracts for a given hodler market.
//In Node.js
import {
MarketDataReaderFactory,
MarketTransManagerFactory,
CHAINS,
} from "definer-hodler.js";
(async function task() {
//Reader
const bnbMainnet = "https://bsc-dataseed.binance.org";
const web3Obj = new Web3(new Web3.providers.HttpProvider(bnbMainnet));
const readerObj = await MarketDataReaderFactory.getNewInstance(
CHAINS.BNB,
2,
web3Obj
);
const stakingAPR = readerObj.getMarketBaseTokenStakingAPR();
const depositMiningAPR = readerObj.getMarketBaseTokenDepositMiningAPR();
const totalDeposit = readerObj.getMarketBaseTokenTotalDeposit();
//TransManager
const account_pkey = "ACCOUNT_KEY";
const account = web3Obj.eth.accounts.privateKeyToAccount(account_pkey);
web3Obj.eth.accounts.wallet.add(account);
const transManagerObj = await MarketTransManagerFactory.getNewInstance(
CHAINS.BNB,
2,
web3Obj
);
const result = await transManagerObj.deposit(

</html>CHAINS has all the chains supported on the Definer platform.
Note: For better performance the HODLer market data is fetched only once from the smart contract and stored in the object created. If the hodler market data needs to be refetched from the smart contract a new object would need to be created.
