echelon-sdk

Quick Start

Install

Install from npmjs:

npm install @preceptlabs/echelon-sdk

And make sure you also install the @aptos-labs/ts-sdk.

Get all markets

import { EchelonClient } from "@preceptlabs/echelon-sdk";
import { Account, Aptos, AptosConfig } from "@aptos-labs/ts-sdk";

// create the aptos instance
const aptos = new Aptos(
  new AptosConfig({
    network: Network.MAINNET,
    fullnode: "your rpc endpoint",
  })
);

const client = new EchelonClient(aptos, "0xc6bc659f1649553c1a3fa05d9727433dc03843baac29473c817d06d39e7621ba");

// get all markets
const markets = await client.getAllMarkets();

Each market has a corresponding coin, to get the coin address:

const market = markets[0]; // use the first market as an example
const coin = await client.getMarketCoin(market);

Borrow/Supply/Replay/Withdraw

Borrow, supply, replay, and withdraw are similar. Let's use Borrow as an example.

First, you need to get the amount of coins the user can borrow:

const borrowable = await client.getAccountBorrowable(account, market);

The user can borrow an amount of coins less than the maximum borrowable. To send the transaction, you can use "@thalalabs/surf" or Aptos wallet adapter. Here is an example using Surf:

import { useSubmitTransaction } from '@thalalabs/surf/hooks';

const payload = client.createBorrowPayload(
  "0x1::aptos_coin::AptosCoin",
  // the market address of APT
  "0x761a97787fa8b3ae0cef91ebc2d96e56cc539df5bc88dadabee98ae00363a831",
  "100000000"
);

// in react:
const {submitTransaction} = useSubmitTransaction()

<button onClick={() => submitTransaction(payload)} />
