AbstractPay

The chain-abstracted payment SDK for seamless stablecoin transactions across blockchains.

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.

Installation

Install AbstractPay using npm:

npm install abstractpay

Usage

Initialize the SDK

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>',
});

// Set the owner's wallet for signing transactions
sdk.setOwnerWallet({
  signMessage: async (hash: string) => {
    return wallet.signMessage(hash);
  },
  signTypedData: async (data: any) => {
    return wallet.signTypedData(data);
  },
});

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.
