The iGaming payment problem

Traditional crypto gateways buckle under casino load.

Coinflux was engineered around the exact failures operators hit every day.

Deposits get stuck when players send the wrong amount.
Deterministic amounts

Coinflux classifies every inbound transfer as EXACT, UNDER, or OVER against what the player promised — and never blocks valid funds. Chain truth wins, so support tickets don’t pile up.

Network congestion delays deposits and frustrates players.
Real-time chain watching

A dedicated watcher tracks each deposit address from broadcast to confirmation, with a configurable confirmation threshold. The moment funds are final, the player is credited.

Platform bugs double-credit a single blockchain transaction.
Idempotent ledger

Every credit carries a unique idempotency key enforced at the database level, inside a transaction. Re-processing the same transfer is a no-op. Double-crediting is mathematically impossible.

Hot wallets get drained because private keys sit on web servers.
Non-custodial by design

You configure only an extended public key (xpub). Coinflux derives and watches receive addresses but can never move a cent. Your keys stay in cold storage — where they belong.

How it works

From player deposit to credited balance — in four steps.

01
Create a deposit
Your casino backend calls the Coinflux API with the player and amount. You get back a fresh USDT-TRC20 address.
02
Player sends USDT
The address is derived from your own xpub — funds land in wallets only you control.
03
Coinflux confirms
The watcher sees the confirmed transfer on-chain and writes an idempotent credit to the ledger.
04
Player gets credited
A signed webhook hits your backend so you top up the player instantly. Signed, verifiable, exactly once.
Built for operators

Everything you need to accept crypto — nothing you don’t.

Multi-tenant dashboard
Every operator gets a login, their own API key, and a live view of every deposit.
Per-tenant API keys
Machine-to-machine auth scoped to each operator. Rotate independently, isolate completely.
Signed webhooks
HMAC-SHA256 over every payload with your own secret. Verify authenticity before you credit.
Watch-only key model

FAQ

Questions operators ask.

What is Coinflux?

A non-custodial crypto payment subsystem for high-volume iGaming. It handles USDT-TRC20 deposits and withdrawals, watches the chain in real time, and credits players through a signed webhook — while operators keep their own keys.

Is Coinflux custodial?

No. You configure only an extended public key (xpub). Coinflux derives and watches receive addresses but can never move your funds. An optional managed-custody mode exists for operators who want it.

How does Coinflux prevent double-credits?

Every credit carries a unique idempotency key enforced at the database level inside a transaction, so re-processing the same blockchain transaction is a no-op. Double-crediting is mathematically impossible.

Which coins and networks are supported?

USDT-TRC20 with automatic on-chain crediting. A manual wallet mode supports any coin or network by uploading a pool of addresses players deposit to, with an approve/reject queue.

How fast is integration?

Create a tenant, paste an xpub, set a webhook, and take your first USDT deposit the same day. Deposits and withdrawals are simple authenticated REST calls with signed webhooks.

How much does Coinflux cost?

Flat monthly pricing: Starter $71/mo, Growth $242/mo, Enterprise custom. No percentage cut of your transactions — unlike processors that charge 0.4–1% per transaction. Every new operator gets a 14-day free trial.

How is Coinflux different from Alphapo or CoinsPaid?

Those are custodial and take a percentage of every transaction. Coinflux is non-custodial — you keep your own keys — and charges a flat monthly fee with a 0% transaction cut. Alphapo, a custodial processor, lost ~$60M to a hot-wallet hack in 2023; non-custodial removes that class of risk because we never hold your funds.

Is there a free trial?

Yes — every new operator starts on a 14-day free trial, no card required, then continues on a flat monthly plan.
