SuperPaymaster

Name: superpaymaster
Author: AAStarCommunity

Decentralized gas payment infrastructure for Web3 agents and dApps. Provides gas sponsorship via community tokens (xPNTs), x402 payment facilitation, and streaming micropayment channels.

Quick Start

pnpm add @superpaymaster/sdk

import { createSuperPaymasterClient } from "@superpaymaster/sdk";

const client = createSuperPaymasterClient({
  network: "base-sepolia",
  operatorUrl: "https://your-operator.example.com",
});

Capabilities

1. Gas Sponsorship (ERC-4337)

Sponsor gas fees for users via community tokens instead of ETH.

// Check if a user is eligible for gas sponsorship
const eligible = await client.isEligibleForSponsorship(userAddress);

// Get paymaster data for a UserOperation
const paymasterData = await client.getPaymasterData(userOp, {
  community: "your-community",
});

2. x402 Payment Settlement

HTTP 402-based payments for API access and agent services.

// Settle a USDC payment via EIP-3009
const result = await client.settleX402Payment({
  from: payerAddress,
  to: payeeAddress,
  asset: "USDC",
  amount: "1000000", // 1 USDC
  signature: payerSignature,
});

3. Micropayment Channels

Streaming payments with off-chain vouchers and on-chain settlement.

// Open a payment channel
const channel = await client.openChannel({
  recipient: serviceAddress,
  token: "USDC",
  totalDeposit: "10000000", // 10 USDC
  duration: 3600, // 1 hour
});

// Sign a micropayment voucher (off-chain, instant)
const voucher = await client.signVoucher(channel.id, "100000"); // 0.1 USDC

4. Agent Identity (ERC-8004)

Register and verify agent identity for reputation-based sponsorship.

// Check agent registration
const isAgent = await client.isRegisteredAgent(agentAddress);

// Get sponsorship rate for an agent
const rate = await client.getAgentSponsorshipRate(agentAddress, operatorAddress);
