PayChains

What it does

Unlike Coinbase Commerce or BitPay, PayChains is fully non-custodial — payments go directly to your wallet. No KYB, no withdrawal delays, no transaction fees. Paste your EVM address, add 3 lines of code, and accept USDC, USDT, ETH across 5 chains (Ethereum, Polygon, BSC, Arbitrum, Base). Includes hosted checkout, recurring subscriptions, webhooks, TypeScript & Python SDKs, and a developer dashboard. Free to start, pure SaaS pricing.

  How to Verify USDC Payments on Base Without a Payment ProcessorFeb 2026 · paywatcher.dev · ▲7

  The Problem Nobody Talks About You want to accept a $10,000 USDC payment. You have two options: Option A: Integrate a payment processor like Coinbase Commerce. Set up an account, embed their checkout widget, handle their SDK. Pay $100 in fees (1%). Option B: Build your own blockchain listener. Learn ethers.js, subscribe to USDC transfer events, handle reorgs, confirmations, edge cases. Two weeks of work, minimum. There's no middle ground. No service that just tells you: "Yes, this specific payment arrived." Until now. https://paywatcher.dev?utm_source=hackernews
