DigitalShield-Pay

DigitalShield-Pay is a non-custodial on-chain payment integration tool for merchants and developers. It creates payment orders, matches incoming USDT or USDC transactions to those orders, and synchronizes payment status through HTTP APIs and webhook notifications. The documented checkout flow sends customers to a hosted checkout, while funds move directly from the payer’s wallet to the merchant’s receiving address.

Practical overview

When it fits

Use it when a merchant system needs to connect order creation and payment confirmation to on-chain USDT or USDC checkout.

Who it is for

  • Merchants adding USDT or USDC checkout to an existing business system.
  • Developers implementing order creation, transaction matching and payment-status handling.

Documented uses

  • Create a server-side payment order and obtain a checkout URL.
  • Match an on-chain payment to a merchant order.
  • Receive payment-status notifications and confirm order state through a query endpoint.
  • Offer USDT and USDC payment options on documented blockchain networks.
Before you choose

Requirements & limits

  • The documented assets are USDT and USDC on Ethereum, BNB Chain, Polygon, Arbitrum, Base, Solana, Sui, TRON and Polkadot AssetHub.
  • The payment flow is described as non-custodial; the service does not take possession of funds or perform transfers or settlement.
  • The documented integration uses signed server-side order creation and recommends webhook verification or an order query; browser redirects are not proof of payment.
  • The repository is public, but its metadata does not specify a license.
  • The README says the service currently charges no platform transaction service fee, excluding blockchain network, wallet and third-party fees; it notes that fee policies may change.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a merchant checkout integration

Configure a receiving option and connect server-side order creation, customer checkout and payment confirmation.

Before you start

  • Merchant dashboard access via QR-code sign-in with WalletConnect.
  • A receiving address and a supported network/token choice.
  • A generated Payment Key; protect credentials and do not commit secrets to a public repository.
  • A merchant server able to make signed HTTP API requests; an optional callback URL for notifications.

Steps

  1. Configure the receiving address and select a supported network/token combination in the merchant dashboard.

  2. Generate a Payment Key and, if needed, configure a callback URL.

  3. Create the payment order server-side with a signed POST /dspay/public/order/create request and receive the order number and checkout URL.

  4. Send the customer to the checkout URL to select a network/token and confirm payment.

  5. Verify the webhook or query the order with POST /dspay/public/order/query; do not treat a browser redirect as payment proof.

Expected outcome

A merchant order is linked to the checkout and can be confirmed through a webhook or order query.

Guide limitations

  • A callback URL is optional; the order-query endpoint is documented as the authoritative fallback.
  • The listed networks and tokens are those named in the repository documentation; availability and transaction finality are not guaranteed.
  • Merchants are responsible for applicable legal and business requirements.
