Add a 0%-fee crypto option to your Shopify store.
Shopify takes a cut on every card sale, and its native crypto options route through third-party custodians. My Crypto Server lets you add a self-hosted crypto checkout to Shopify that settles straight to your own wallet, using the REST API and signed webhooks to mark orders paid.
Connect via the REST API + signed webhooks (draft orders / checkout link).
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.
Offer crypto as an option, create a charge via the API for the cart total, and send the customer to the hosted checkout. Use the Admin API to mark the order paid when the webhook confirms.
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.
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.
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.
The customer picks their chain and coin at checkout; your code just creates a charge in USD. Native coins plus USDC, USDT, and DAI are all handled server-side.
No. It's your own self-hosted gateway that you connect to Shopify through the REST API and webhooks, so there's no third-party app taking a cut or holding your funds.
Yes. Keep cards on Shopify Payments and add crypto as an extra option. Crypto orders settle to your wallet at 0% platform fees.
No. Payment addresses derive from your own wallet, so crypto lands directly with you. The server only detects and confirms payments.
