Getting Started

stbl-sdk is a JavaScript SDK or a API wrapper for the vault contract using usdc.

stbl-sdk simplify the process of minting and withdrawing the cash from the vault.

It is a simple, easy to use, and powerful API for interacting with Stbl Protocol.

You can use Stbl-sdk on node server, browser, or mobile.

You can install stbl-sdk either using NPM .

Inside your project directory, run the following command:

npm install stbl-sdk@0.4.4

Usage

Using stbl-sdk is way easier, you can import the library in your project and use it.

import { stblsdk } from "stbl-sdk";

API Operation

Here is an example of how to mint the $CASH:

const { createAlchemyWeb3 } = require("@alch/alchemy-web3");
const web3 = createAlchemyWeb3(alchemyKey);

1) Check allowance of $USDC on the vault address using

let allowance = await stblsdk.allowanceCheck(web3,walletAddress)

2) If allowance is not sufficient call approve function using

const tx = Promise.resolve(
      await stblsdk.ApproveVault(web3,amount,walletAddress)
    );
    tx.then((res) => {
      console.log(res);
    });

3) Mint $CASH using $USDC

const tx = Promise.resolve(
      await stblsdk.Mint(web3, amount, walletAddress)
    );
    tx.then((res) => {
      console.log(res);
    });

// amount = the amount of $USDC you want to exchange for $CASH
// walletAddress = account which will be doing the transaction
// web3 is an instance of web3 show be polygon mainnet rpc in alchemy key

Here is an example of how to withdraw the $CASH:

````js
const { createAlchemyWeb3 } = require("@alch/alchemy-web3");
const web3 = createAlchemyWeb3(alchemyKey);

1) Check the balance if its sufficient or not using

let balanceOf = await stblsdk.balanceOf(web3,walletAddress)

2) Withdraw Transaction

const tx = Promise.resolve(
      await stblsdk.Withdraw(web3, amount, walletAddress)
    );
    tx.then((res) => {
      console.log(res);
    });

// amount = the amount of $CASH you want to exchange for $USDC
// walletAddress = account which will be doing the transaction
// web3 is an instance of web3 show be polygon mainnet rpc in alchemy key
