How it works

From invoice to on-chain settlement in three steps.

1

Create a store

Set up your storefront in under two minutes. Configure supported chains, set your processing fees, and generate API keys — no blockchain expertise required.

2

Generate a payment request

Create a USD-denominated invoice via our REST API or dashboard. Share the payment link with your customer — they pick their preferred cryptocurrency at checkout.

3

Get paid

Your customer sends crypto to a unique address. We detect the transaction on-chain and confirm it instantly via webhooks. Funds settle directly to your wallet — no middlemen.

Features

Everything you need to accept crypto. Nothing you don't.

[*] Multi-chain support

BTC, ETH, LTC, BCH, BSC, Polygon, TRON — with more chains added continuously from the admin panel. Each chain is independently configurable.

[*] Self-hosted, self-sovereign

Deploy on your own infrastructure. You control the master seed, the keys, and the funds. No third party can freeze, censor, or touch your payments.

[*] Dead-simple REST API

One endpoint to create a payment request. Clean JSON, API key auth, comprehensive error handling. Integrate in minutes — SDKs coming soon.

[*] Real-time exchange rates

USD-denominated invoices with live crypto conversion at payment time. Rates locked for the duration of the payment window via CoinGecko.

[*] Automatic payment detection

Dual-path confirmation: tatum webhooks for instant notification plus on-chain polling as a fallback. Payments are never missed.

[*] No platform fees

You pay only blockchain network fees. You can set your own processing fee per chain — a flat USD amount added to each invoice. We take zero commission.

[*] HD wallet architecture

BIP44-compliant hierarchical deterministic wallets. A new address is derived for every payment — no address reuse, better privacy for your customers.

[*] Built for developers

Webhook callbacks, detailed transaction logs, access audit trails, and a clean admin panel. Built by developers who actually use crypto.

For developers

One endpoint.
Infinite possibilities.

Creating a crypto payment takes a single API call. Pass the amount in USD, identify your customer by email, and we handle the rest — chain selection, address derivation, exchange rate locking, and payment confirmation.

  • RESTful. JSON in, JSON out.
  • Authenticated via API keys with SHA-256 hashing.
  • Webhook callbacks for payment status changes.

Why self-hosted

You wouldn't hand your private keys to a stranger. Don't hand over your revenue.

Every hosted payment processor is a middleman that can freeze your funds, raise fees, or shut down your account without warning. Bixmerchant runs on your server — you control the full stack, from the master seed to the payment confirmation logic.

No freezes

No payment processor can block your funds, freeze your account, or impose reserve requirements. The money moves directly to your wallet.

No surprises

No sudden fee hikes, no terms-of-service changes that kill your business model. The code is yours, the pricing is yours.

No lock-in

Your keys, your HD wallet, your addresses. If you ever decide to leave, take your wallet with you. BIP44 standard means portability.
