USDC checkoutfor any Shopify store.
Install the Mailgent Pay app from the Shopify App Store and the next checkout shows USDC alongside cards. Orders flow into the Shopify admin you already use. Refunds, customer records, fulfillment — all in the same place, nothing new to learn.
Most crypto payment apps for Shopify are bolt-ons: they ship a parallel admin, a parallel reporting surface, and a parallel ledger. Six months in, the merchant has two sources of truth and a reconciliation nightmare. Mailgent Pay is installed as a native Shopify payment method — every USDC order is a regular Shopify order, with the gateway tagged. Refunds happen in the admin you already use. Reporting flows through the same exports. Customers, products, inventory, and fulfillment behave exactly the way they always did.
How it works
Four steps. Most fire in under a second.
Install from the App Store
Search 'Mailgent Pay' in the Shopify App Store. Install. Authorize the standard Shopify scopes (read_orders, write_orders, read_inventory). The connection takes about 30 seconds.
Enable the payment method
In Shopify admin → Settings → Payments → Manual payment methods, enable Mailgent Pay. Optionally enable test mode to dry-run with simulated USDC before going live.
Customers check out
On the next checkout, customers see USDC as a payment method. They sign with their Mailgent wallet (or connect an external wallet). The order appears in admin as paid, gateway = Mailgent Pay.
Fulfill, refund, report — as usual
Fulfillment, refunds, and reporting all run through the standard Shopify admin. The Mailgent app surfaces extra detail (chain link, signed receipt) but does not replace the admin you already know.
What you get
Built for developers who already shipped.
App Store install
Find Mailgent Pay in the Shopify App Store, click install, complete a 60-second connection flow. The next checkout offers USDC as a payment method beside the merchant's existing gateways.
Native order sync
Every USDC order appears as a regular Shopify order with the Mailgent Pay gateway tagged. Fulfillment, inventory, customer history, and notifications all behave the way merchants expect.
Automated payouts
USDC accumulates in the project wallet. Schedule daily, weekly, or threshold-based payouts to a treasury address or off-ramp partner. No 1099-K surprises; the activity log shows every payout with a chain link.
Refunds in the admin
Issue a refund the standard Shopify way (full or partial). The Mailgent Pay gateway signs the reversal, sends USDC back to the buyer wallet, updates the order status, and fires the refund webhook.
On-chain audit trail
Every order links to a Base transaction. Auditors see a one-to-one mapping between Shopify order number, Mailgent signed receipt, and on-chain settlement. Reconciliation takes minutes, not days.
Hydrogen + Shop Pay aware
Works with custom storefronts (Hydrogen, Oxygen, headless) through Shopify Functions. Plays well with Shop Pay — Mailgent shows up as an additional method, not a replacement.
What people build
Real-world shopify flows shipping today.
Apparel + consumer goods
Add USDC to a DTC store that already takes Shop Pay and credit cards. The treasury picks up a low-friction crypto-native customer segment without disrupting the existing checkout.
Digital products + downloads
Sell PDFs, software licenses, video content. USDC is a perfect fit for cross-border digital sales — no FX, no card decline, no chargeback risk on intangible goods.
Wholesale + B2B orders
Large orders that exceed daily card limits or trigger fraud holds settle cleanly in USDC. No multi-day clearing, no manual treasury wire reconciliation.
Subscription boxes
Mailgent mandates power recurring USDC charges. Customers grant a monthly cap at signup; the Shopify subscription app charges on the cycle without re-prompting.
