NON-CUSTODIAL • 0% COMMISSION • NO KYC
Accept USDT & USDC directly without handing your checkout to third-party processors.
0xGate (CryptoGateway) is autonomous, non-custodial payment infrastructure you run on your own terms. Each checkout gets a dedicated blockchain address derived keylessly via your account-level XPUB. The real-time tracker daemon verifies on-chain deposits and notifies WooCommerce server-to-server—zero middlemen, zero account freezes, and 0% ongoing processing fees.
Keyless Server Security
Your server never stores private keys or seed phrases. Addresses are generated dynamically using BIP44 extended public key (XPUB) derivation. Funds stay locked under your master wallet until you sweep offline.
Zero-Rejection Engine
Built-in exchange withdrawal fee slippage tolerance (covers Binance/Bybit $0.80–$1.00 fees) and cross-chain mistake recovery (detects if a buyer accidentally sends Polygon USDT instead of BSC USDT).
Server-to-Server Verification
Eliminates fake webhook spoofing. WooCommerce verifies every payment directly against the gateway API before marking orders paid, preventing order reference collisions and duplicate invoice reuse.
HOW IT WORKS
From customer checkout to your cold storage.
- Unique Checkout Invoice: WooCommerce or your payment link generates a dedicated payment address, QR code, and 1-click Web3 wallet button (MetaMask, Phantom, Trust Wallet).
- Automated Blockchain Tracking: The tracker daemon scans TRON, BSC, Polygon, and Ethereum every 20 seconds. It handles exact payments, partial payments, and top-ups seamlessly.
- Cryptographic Webhook Dispatch: Once verified on-chain, 0xGate posts a secure event to your store and sends an instant email notification to your admin inbox.
- Offline Cold Consolidation: Sweeping is done locally on your machine via our offline derivation sweeper. Your spending keys never touch the internet-facing server.
CONTROL & MULTI-STORE TENANCY
Run multiple stores or accept payments for clients on one gateway.
Each store or brand gets isolated reference tracking (`idx_user_site_merchant_ref`), custom identifiers, and individual webhook destinations. Simultaneous customer checkouts across different stores never collide.
Choose a single master wallet for all incoming store revenue, or establish separated operational accounts and hardware cold-storage destinations for enterprise isolation.

FREQUENTLY ASKED QUESTIONS
Common questions from merchants and operators.
Are there any monthly subscription fees or transaction commissions?
No. The Sovereign Self-Hosted Edition has 0% transaction fees forever. You keep 100% of every payment minus standard public blockchain network gas fees.
Can customers pay using centralized exchanges like Binance or Bybit?
Yes. The gateway includes smart exchange withdrawal fee slippage tolerance, automatically approving orders even if the exchange deducts an unexpected $0.80–$1.00 fee from the customer’s transfer.
What happens if a customer sends a partial amount or the wrong token?
If a customer sends a partial deposit, the checkout screen updates in real time to show the exact remaining balance needed. If they send USDC instead of USDT, or deposit on Polygon instead of BSC, the gateway’s cross-chain recovery engine automatically identifies the deposit and credits the order.
Do I need to leave my local computer running?
No. The VPS handles checkout presentation, continuous blockchain transaction scanning, and WooCommerce order updates 24/7. You only use your local computer when you decide to run the offline sweep tool to transfer funds to cold storage.
