Overview

jscobosafe is a JavaScript SDK for sending transactions via Cobo Safe in the same way as ethers.js. Head to https://github.com/coboglobal/jscobosafe for the source code.

​
Installation

npm i git+https://github.com/coboglobal/jscobosafe

​
Usage

Your .env configuration 
PRIV = <Private key of the delegate>
COBOSAFE = <Address of CoboSafeAccount>
The code performs a transfer of WMATIC ERC20 token on Polygon network. 
const {CoboSafeAccount} = require("jscobosafe");
const {ethers} = require("ethers");
const ERC20_ABI = require("./ERC20.json");

require("dotenv").config();
const PRI_KEY = process.env.PRIV;
const COBO_SAFE_ADDRESS = process.env.COBOSAFE

const provider = new ethers.JsonRpcProvider("https://rpc.ankr.com/polygon")
const signer = new ethers.Wallet(PRI_KEY, provider);
const coboSafe = new CoboSafeAccount(COBO_SAFE_ADDRESS, signer)
const delegate = coboSafe.delegate;

const WMATIC_ADDRESS = "0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270";

async function main(){
    console.log("CoboSafe", coboSafe.address);
    console.log("Safe", await coboSafe.safe());
    console.log("Delegate", coboSafe.delegate);

    let tx;

    // Connect with the contract as other ethers.js signers do.
    const token = new ethers.Contract(WMATIC_ADDRESS, ERC20_ABI, coboSafe);

    console.log(await token.balanceOf(await coboSafe.safe()))
    tx = await token.transfer(delegate, 1);
    await tx.wait()
    console.log(await token.balanceOf(await coboSafe.safe()))
}

main().catch((error) => {
    console.error(error);
    process.exitCode = 1;
});
