⚡ Quick Start

npm install [email protected]

Basic Payment

import { StakefyX402Client } from 'x402-stakefy-sdk';

const client = new StakefyX402Client({
  apiUrl: 'https://stakefy-x402-production.up.railway.app',
  network: 'mainnet-beta'
});

const payment = await client.createPayment({
  amount: 0.1,
  merchantId: 'YOUR_WALLET',
  reference: 'order-123'
});

Social Payments

import { payToX } from 'x402-stakefy-sdk';

// Pay by username!
await payToX(client, '@creator', 0.25);

Budget Presets

import { oneShot, perMinute, perMonth } from 'x402-stakefy-sdk';

await oneShot(client, merchant, user, 100, 0.01);  // 100 payments
await perMinute(client, merchant, user, 0.1, 60);  // $0.10/min
await perMonth(client, merchant, user, 9.99);      // $9.99/month

🏢 NEW: Enterprise Features

import { createEnterpriseClient } from 'x402-stakefy-sdk';

const enterprise = createEnterpriseClient(API_URL);

// Organization badges
const badge = await enterprise.getOrgBadge('org-123');

// Usage quotas
const quota = await enterprise.getQuota('org-123', 'project');

// Analytics
const metrics = await enterprise.getMetrics('org-123', 'project', 'month');

// Invoices
const invoice = await enterprise.generateInvoice('org-123', '2024-10', receipts);

🔐 NEW: Receipt Verification

import { verifyReceipt, verifySession } from 'x402-stakefy-sdk';

// Cryptographic proof with SHA-256
const receipt = await verifyReceipt({
  signature: 'TX_SIG',
  expectedAmount: 0.1,
  expectedMerchant: 'WALLET'
}, connection);

console.log(receipt.proof);     // SHA-256 hash
console.log(receipt.verified);  // true

🚀 NEW: Solana Primitives

Fast Escrow

import { FastEscrow } from 'x402-stakefy-sdk';

const escrow = new FastEscrow(connection);
await escrow.create({ buyer, seller, amount: 10, timeout: 3600 });
await escrow.release(escrowId);

Partial Settlement

import { PartialSettler } from 'x402-stakefy-sdk';

const settler = new PartialSettler();
await settler.settle({ channelId, amount: 1.0, nonce: 1, merchant });

Drift Protocol

import { DriftX402 } from 'x402-stakefy-sdk';

const drift = new DriftX402('MERCHANT', 0.01);
const trade = await drift.trade({ market: 'SOL-PERP', side: 'long', size: 1, leverage: 10 });
