Turn manual USDT transfers into checkout.

The gap

USDT is easy to send. Matching it to an order is not.

Capabilities

What the managed installation includes

Implementation

Why managed integration

This is a managed installation into one existing website or backend — not a self-service plugin and not a multi-asset payment gateway. We review the checkout you already use, install the branded payment interface, and enable live wallets only after the payment states are tested.

1. 1Review the current checkout, order records, and backend
2. 2Connect sandbox and confirm payment-session creation
3. 3Install the branded payment interface (QR, amount, network, expiry)
4. 4Configure signed webhooks to the merchant endpoint
5. 5Test all nine payment states: created, pending, confirming, confirmed, underpaid, overpaid, expired, failed, and manual-review
6. 6Enable live wallets only after sandbox testing and security validation
7. 7Monitor the first live transactions with the merchant

Conditions

Commercial & operational conditions

These conditions describe how the service operates. They are not legal advice.

• The merchant controls the public receiving wallet and the private keys. MakeMeACoin does not request or store seed phrases or private keys.
• Customer payments go to the merchant’s verified receiving wallet. MakeMeACoin does not deduct its platform fee from that on-chain transfer and does not hold the principal.
• The platform fee is a commercial charge on confirmed payment volume recorded by the system in a calendar month, billed monthly.
• Confirmed volume means payment sessions that reach the confirmed status in the system. Other statuses are not included in the fee calculation.
• Refunds are sent by the merchant from the merchant’s own wallet. MakeMeACoin cannot sign withdrawals on your behalf.
• Legal, tax, AML, sanctions, and customer-compliance responsibilities depend on the merchant’s jurisdiction and business.
• Blockchain network fees, and any fees charged by the merchant’s wallet or RPC providers, may apply separately.
• The standard managed integration covers one existing website or backend, TRON and BNB Chain, sandbox, payment UI, signed webhooks, nine-state testing, live validation, first-transaction monitoring, and 30 days of implementation support. Work outside that scope is quoted separately.
• Dedicated managed support or custom development after the 30-day implementation window is quoted separately.
• Scope and timeline are confirmed after the integration review. Implementation time depends on the existing checkout and backend.
• Live wallets are enabled only after sandbox testing and security validation.
• A transfer sent on a different network than the one selected at checkout is not matched to that session. Recovery is not always possible.
