Crypto Payment Gateway for Casino Operators — 50+ Coins, On-Chain
Accept deposits and process payouts in BTC, ETH, USDT, TON, TRX and 50+ tokens. Direct on-chain settlement, sub-minute confirmations, automated hot wallet balancing, full ledger reconciliation for iGaming operators.
Supported Assets
50+ Coins Across 8 Blockchains
Every major cryptocurrency your players hold — integrated natively into your casino cashier with live exchange rates and per-coin deposit addresses.
How It Works
Blockchain Transaction Flow
Each deposit passes through five stages with automated confirmation monitoring and instant balance crediting. Average end-to-end latency under 60 seconds on TRON and TON.
Payouts
Instant Crypto Payouts at Scale
Process thousands of withdrawals per hour with automated batch signing, whitelisted destination wallets, and gas optimization that cuts network costs by up to 60%.
Batch Payout Engine
Queue thousands of withdrawal requests and settle in a single on-chain transaction batch. Reduces gas costs and processing overhead by consolidating outputs across players.
Whitelisted Wallets
Operators define approved destination wallets. Any payout to a non-whitelisted address triggers a mandatory manual review and four-eyes approval before broadcast.
Gas Optimization
Dynamic fee estimation selects optimal gas settings per network condition. Scheduled payouts route to off-peak windows for ETH, reducing miner fees without impacting player experience.
Infrastructure
Hot / Cold Wallet Architecture
Institutional-grade custody separates operational liquidity from cold storage reserves. MPC signing and multi-sig cold storage protect operator funds at every layer.
Hot Wallet Layer
- MPC (multi-party computation) key signing — no single key ever exists
- Automated replenishment from cold storage when balance falls below threshold
- Per-coin balance monitoring with real-time alerts
- IP-whitelist and 2FA on all hot wallet API access
- Sub-second signing for outbound payouts
Cold Storage Layer
- HSM-backed multi-sig — requires M-of-N approvals for withdrawals
- Geographically distributed key shards across independent facilities
- Air-gapped signing for large-value transfers
- Quarterly proof-of-reserve attestation available on request
- Non-custodial option: operator controls signing keys end-to-end

Compliance
AML Screening on Every Transaction
Integrated Chainalysis KYT and Elliptic risk intelligence screen every deposit wallet before funds are credited. Sanctioned addresses are blocked in real time.
Chainalysis KYT
Real-time transaction monitoring via Chainalysis Know Your Transaction. Risk scores calculated per address cluster with automated hold triggers on medium and high-risk deposits.
Elliptic Integration
Optional Elliptic risk intelligence as a secondary screening layer. Operators select their preferred provider or run both in parallel for maximum coverage.
Sanctions Blocking
OFAC, EU, UN sanctions lists updated in real time. Blacklisted wallet addresses refused at deposit and withdrawal stages with full audit log and SAR export capability.
Player Experience
Frictionless Mobile Deposit Flow
Players see a familiar, fast cashier experience — select coin, scan QR, wait for confirmation. No clipboard errors, no failed transactions, no support tickets.
Unique Deposit Address
Every player receives a unique on-chain address per coin, eliminating mix-up risks. Addresses rotate after each transaction for enhanced privacy and traceability.
QR Code Scanning
Auto-generated QR codes encode amount and address. Players scan directly from their mobile wallet app — compatible with Trust Wallet, MetaMask, Tonkeeper, and 20+ wallets.
Live Confirmation Status
Real-time confirmation counter displayed in the cashier. Player balance updates the moment the threshold confirmations are reached — no page refresh, no waiting for support.

2FA Enforcement
All operator dashboard actions require TOTP or hardware key second factor. No exceptions for withdrawal approvals.
IP Whitelist
API and dashboard access restricted to operator-specified IP ranges. All access attempts logged with geo-tagging.
Immutable Audit Logs

SOC 2 Type II
Infrastructure audited under SOC 2 Type II framework. Reports available to enterprise operators under NDA on request.
Social Proof
Trusted by iGaming Operators Worldwide
“The crypto payment gateway cut our deposit failure rate to near zero on TRON and TON. Players stopped contacting support about missing deposits within the first week.”
“On-chain settlement at 0.5% with no monthly minimum was the reason we switched. Our previous processor charged 2.5% and had a $2,000 monthly fee regardless of volume.”
“Chainalysis KYT integration was a compliance requirement for our license. CastillioGaming had it built in — saved us three months of custom integration work.”
