Binance QR Integration Architecture

Solves the #1 Exchange Checkout Bug: Withdrawal Fee Shortfalls

When a buyer withdraws $50.00 USDT from Binance on BSC or Arbitrum and Binance deducts a $0.15–$0.30 network fee, custodial gateways leave the order stuck as "Partially Paid". XPayr 1% (max $0.50) Underpayment Tolerance auto-clears the order and fires payment.underpaid_accepted!

100% Sin Custodia — Zero Custodial Binance Merchant Account Required

Unlike Binance Pay (which holds your funds in a custodial exchange sub-account and restricts jurisdictions/industries), XPayr settles directly on-chain into your own Ledger, Safe, or MetaMask/TronLink wallet.

6-Second Background Explorer Polling + Instant TxID Paste

As soon as Binance broadcasts the withdrawal hash on BSC, Solana, Base, Arbitrum, or TRON, XPayr verifica the exact transfer on-chain and completes fulfillment automatically.

Exchange Binance y QR de App Checkout — Preguntas frecuentes

Do I need a Binance Pay merchant account to accept Binance users on XPayr?

No! XPayr works via standard on-chain crypto withdrawals from any Binance user account (or Binance Web3 Wallet) directly to your non-custodial wallet — zero Binance Pay KYB required.

What happens if Binance deducts a $0.20 USDT withdrawal fee from a $40 order?

With XPayr 1% (máx. $0.50 USD) underpayment tolerance enabled, the $39.80 net receipt is within the $0.40 (1%) threshold, so XPayr marks the invoice completed automatically and sends a signed payment.underpaid_accepted webhook.

Which network is fastest and cheapest when withdrawing USDT/USDC from Binance?

Red BNB Smart Chain (BEP-20), Solana, Red Arbitrum One, Polygon, Base, and TON typically have $0–$0.20 Binance withdrawal fees and confirm in seconds.
