Universal Login

Create an account in seconds

Create an account in seconds. No need for a deep understanding of crypto. No need to install any dedicated software. Just like you always wanted.

Best fiat on-ramp

An account is only useful if it contains funds. Top-up your account instantly with a card or a bank account. No context switching. No exchanges. It just works.

Secured by design

What if your device is lost or stolen? No problem. Access your account from other devices and block the malicious device from accessing your funds.

Simpler transaction fees

Pay transactions fees with your favorite token. We make the user experience so good, users don't need to know they're using a blockchain.

Getting started

With Universal Login you can start creating applications in JavaScript in a few minutes.

									
	$ npm install @universal-login/sdk

1. Initialize the SDK:

									
const UniversalLoginSDK = require('@universal-login/sdk').default;

const sdk = new UniversalLoginSDK(
	'https://relayer-rinkeby.herokuapp.com',
	"https://rinkeby.infura.io/v3/access-token"
);

await sdk.start();

2. Deploy your wallet contract:

									
const GAS_PRICE = '11000000000';
const GAS_TOKEN = '0x0000000000000000000000000000000000000000';

const {
  waitForBalance,
  deploy,
  privateKey,
  contractAddress
} = await sdk.createFutureWallet();
await waitForBalance(); // it waits for you to send ether to 'contractAddress'

let {waitToBeSuccess} = await deploy(
  'yourname.poppularapp.test',
  GAS_PRICE,
  GAS_TOKEN
);
const wallet = await waitToBeSuccess();

3. Send your message:

									
const message = {
  from: contractAddress,
  to: '0xf4C1A210B6436eEe17fDEe880206E9d3Ab178c18',
  data: '0x',
  value: '1',
  gasToken: '0x0000000000000000000000000000000000000000',
  gasPrice: '11000000000',
  gasLimit: '500000'
};
({waitToBeSuccess} = await sdk.execute(message, privateKey));
await waitToBeSuccess();
