Direct-to-Wallet Crypto Payment Gateway for Web Hosts & Businesses
Accept BNB, BTC, ETH, USDT, USDC, SOL, LTC, and DOGE with zero middleman custody. Payments go directly to the saved wallet and are credited only after destination, asset, amount, transaction success, and required confirmations are verified.
Keep 100% of your earnings with zero transaction cuts or fees.
Bitcoin, BSC, Ethereum, Solana, USDT, USDC, LTC, DOGE.
Instant broadcast detection in seconds with Server-Sent Events.
Deterministic BIP-84/44 xPub generation. Zero keys stored on server.
What We Are Offering
Engineered specifically for web hosting companies, SaaS providers, and high-volume online businesses demanding total financial autonomy and zero middleman interference.
Direct Cold Wallet Settlement
BIP-84 (Native SegWit Bech32) and BIP-44 xPub address derivation. Your private keys never touch the web server. Customer funds settle directly to your hardware Ledger, Trezor, or cold wallet.
Multi-Chain & Multi-Token
Support for BNB, Bitcoin, Ethereum, Solana, Litecoin, Dogecoin, plus USDT (BEP-20, ERC-20, SPL) and USDC. Offer ultra-low gas fee options like BSC USDT with ~$0.15 transfers.
Bulletproof 1-Domain Isolation
Strict 1:1 binding between merchant accounts and registered host domains. Dedicated merchant API keys, unique derivation paths, and an immutable invoice ledger tied to your domain.
Dynamic Network Gas Buffer
Adds a configurable per-network checkout buffer to reduce withdrawal-fee shortfalls. The sender still pays the actual miner or gas fee charged by their wallet or exchange.
Mempool Catching & SSE
The verifier polls active invoices every 12 seconds and streams checkout updates. An invoice completes only after the configured confirmation threshold.
WHMCS Module & PHP SDK
Turnkey WHMCS payment gateway module ready for upload into /modules/gateways/ plus a zero-dependency PHP client (CryptoGatewayClient.php).
Relational MySQL Ledger
Full relational ledger storing merchant accounts, address derivation indices, invoices, on-chain transaction hashes, exchange rates, and webhook delivery logs for audit readiness.
Enterprise Security & 2FA
TOTP two-factor authentication, PBKDF2 password hashing with salt, cryptographically secure HMAC-SHA256 webhook signatures, and sliding-window rate limiting on all public endpoints.
Interactive Live Checkout Preview
Test drive the client checkout widget below. Switch cryptocurrencies, examine dynamic network fee calculation, and simulate an instant mempool payment confirmation.
High-Performance NVMe VPS (1-Year)
Supported Assets & Networks
Supported routes use transaction-level chain verification. Bitcoin and EVM wallets may use public-key derivation; Solana, Litecoin, and Dogecoin use explicitly saved receiving addresses.
