Whether you run Express, Fastify, or NestJS, My Crypto Server drops into a Node.js backend cleanly. Create charges with the TypeScript SDK or REST API, verify signed webhooks, and settle every payment straight to a wallet you own.
TypeScript SDK / REST API from Node + a signed webhook handler.
Integration
Push the app to Vercel, attach any Postgres database, add your Alchemy key, and point it at your wallet. You're live in about an hour.
Use the SDK or REST API to create a charge for the order total. Add a webhook route that verifies the HMAC-SHA256 signature before marking the order paid.
On a confirmed payment, the server sends a signed webhook to your endpoint. Verify the signature, then mark the order paid and fulfil, idempotently.
Test with the live demo flow, then flip it on. Card options can stay exactly where they are; crypto simply runs alongside them at 0% fees.
Create charges and read payment state from a TypeScript SDK or the REST API. The same primitives power the dashboard, so anything the UI does, your code can too.
Every confirmed payment fires an HMAC-SHA256 signed webhook with replay protection, so your app marks orders paid idempotently and never trusts an unverified event.
Payments derive from your own wallet and settle straight to you. There's no processor balance, payout schedule, or account anyone can freeze.
No 2.9% + 30¢ per order. Crypto settles for the cost of gas, paid by the customer, so your integration keeps the full sale price.
Any of them. The SDK and REST API are framework-agnostic, so Express, Fastify, NestJS, or a plain HTTP server all work.
Verify the signature and timestamp on the raw body before acting, and make the handler idempotent so a retried delivery can't double-fulfil an order.
Yes. Addresses derive from your own wallet, so payments land with you, non-custodially.
