How to use

install

yarn add @mclb/lending-api ethers @hovoh/ethcall

@hovoh/ethcall is a package for multicalls. If you're not using multicalls you don't need to install it.

Using the api

Initialise your ProvidersRegistry from EVMContractsRegistry and use the initMaiApi(providers: ProviderRegistry) to initialise the API.

import {providers} from "@hovoh/evmcontractsregistry";
import {initLendingClubApi, LendingClubApi} from "@mclb/lending-api";

const lcApi: LendingClubApi = initLendingClubApi(providers);

The LendingClubApi object has two NetworkContractsRegistry:

1. vaults has all the vaults
2. peripherals has all the other contracts. It also has the bindings to call arbitrary vaults.

Examples:

To query a vault (using multicalls):

        const [symbol, closingFee] = await vaults.forNetwork(Network.OPERA_MAINNET).multiCall((get) => [
            get("WFTMVault").symbol(),
            get("WFTMVault").closingFee()
        ])

To query vault available funds:

import {Network} from "@hovoh/evmcontractsregistry";
const wftmVault = lcApi.vaults.forNetwork(Network.OPERA_MAINNET)
    .getContractInstance("WFTMVault");
const maiBorrowAvailable = maiApi.peripherals.forNetwork(Network.OPERA_MAINNET).getContractInstance("mUSD").balanceOf(wftmVault.address)
