yarn add @usekeyp/js-sdk

Usage 📖

Authenication using NextAuth.js

Configure using the Keyp NextAuth provider

// pages/api/auth/[...nextauth].js
import { KeypAuth } from "@usekeyp/js-sdk";
import NextAuth from "next-auth";

const NextAuthOptions = KeypAuth({
    clientId: process.env.KEYP_CLIENT_ID, // From dev portal
    secret: process.env.KEYP_COOKIE_SECRET, // Random string
    redirectUrl: "http://localhost:3000/api/auth/callback/keyp",
});

export default NextAuth(NextAuthOptions);

Trigger a login for a specific social provider using signInKeyp()

import { signInKeyp } from "@usekeyp/js-sdk"

export default function SignInPage() {
    return (
        <div>
        <button onClick={() => signInKeyp("GOOGLE")}>Sign in with Google</button>
        <button onClick={() => signInKeyp("DISCORD")}>Sign in with Discord</button>
        </div>
    )
}

ERC20 and ERC721 token transfers

import { tokenTransfer } from "@usekeyp/js-sdk";
import { useSession } from "next-auth/react";

const { data: session } = useSession();
const ACCESS_TOKEN = session.user.accessToken

const data = {
    accessToken: ACCESS_TOKEN,
    toUserUsername: "pi0neerpat#1337",
    toUserProviderType: "DISCORD",
    tokenAddress: '0x8f3Cf7ad23Cd3CaDbD9735AFf958023239c6A063',
    tokenType: 'ERC20',
    amount: '.01',
}

const result = await tokenTransfer(data)

Read and write smart contracts

import { readContract, writeContract } from "@usekeyp/js-sdk";
import { useSession } from "next-auth/react";

const { data: session } = useSession();
const ACCESS_TOKEN = session.user.accessToken

// Read from a smart contract
const resultWrite = await readContract(
    {
        accessToken: ACCESS_TOKEN,
        address: "0x2791bca1f2de4661ed88a30c99a7a9449aa84174",
        abi: "balanceOf(address) public view returns (uint256)",
        args: ['0x8f3Cf7ad23Cd3CaDbD9735AFf958023239c6A063'],
    });

// Write to a smart contract
const resultRead = await writeContract(
    {
        accessToken: ACCESS_TOKEN,
        address: "0x55d4dfb578daa4d60380995fff7a706471d7c719",
        abi: "pay(uint256,uint256,address) public returns (bool success)",
        args: ['1', '10000000', '0x9ca6a77c8b38159fd2da9bd25bc3e259c33f5e39'],
    });
