AbstractPay is a powerful, Convenient, and secure SDK designed to make cross-chain payments simple and fast. With AbstractPay, developers can enable users to spend and accept fragmented stablecoins from any chain to any chain in seconds.

Features

• Fast: Payments complete in seconds.
• Convenient: Let your users pay with any stablecoin, from any chain.
• Simple: Pay in a single step.
• Secure: No extra counterparties—AbstractPay never holds user funds.

Use Cases

1. For Developers:
   Onboard users from any chain and allow them to always pay using fragmented stablecoins.
2. For DApps:
   Accept payments from any chain and provide users with the simplicity of always paying in stablecoins.

Usage

For API key access, reach out to us directly via direct message or email.

import { AbstractPay } from 'abstractpay';

const sdk = new AbstractPay({
  apiKey: '<your-api-key>',
  baseUrl: '<api-base-url>',
  testnet: boolean // optional, default: false
});

// Set the owner's wallet for signing transactions
sdk.setOwnerWallet(wallet);

One click payment

const paymentParams = {
  receiverAddress: '<recipient-address>',
  amount: '2.2', // amount in dollars
  destinationChain: 421614, // Arbitrum sepolia
  destinationToken: '0x75faf114eafb1BDbe2F0316DF893fd58CE46AA4d', // USDC
  orderType: 'p2p',
  senderAddress: '<sender-address>',
};

const order = await sdk.pay(paymentParams);
console.log('Order Created:', order);

Other Example Workflow

1. User Initiates Payment: The DApp calls initialisePayment to create a payment order.
2. User Signs the Order: The SDK handles signing of the order hash.
3. Payment Submission: The signed payment is submitted to AbstractPay's backend for processing.
