Security by design
Your wallet stays yours.
Dedyx is non-custodial payment infrastructure. We handle the checkout experience and payment signals. You keep control of your funds.
Non-custodial architecture
Funds go directly from the customer to the merchant’s TRON address. Dedyx does not hold cryptocurrency, receive private keys or perform withdrawals. Refunds remain the merchant’s responsibility.
Server-side API access
Merchant requests use an API key on the backend. Checkout links expose only the data needed to pay that order. Keys and rotation secrets should never appear in customer browser code.
Payment verification
Dedyx checks confirmed USDT TRC-20 transfers and a successful solidified TRON receipt. Recipient, exact amount and blockchain timestamp are checked against the order. Previously recorded transaction events cannot pay another order.
Signed webhook communication
Each merchant receives a separate signing key. Verify HMAC signatures over raw request bytes, reject stale requests and deduplicate event IDs before taking a business action. Read the webhook guide.
Focused interfaces
The public product is an API and hosted checkout, with no account dashboard. Merchant endpoints require authentication. Payment confirmations are processed separately from the public API; HTTPS webhook targets are checked before delivery.
Sequential reuse of an address matches orders by exact amount and time window. A repeated old payment sent during a new matching window cannot be distinguished by intent. Understand address reuse.
