Casino API with Crypto Payments (2026)

Crypto casinos crossed $81B in GGR in 2025, growing 3x faster than fiat casinos. The tech stack matters: pick the wrong wallet architecture and you're stuck with 10-minute deposit delays and 3% chain fees.

Supported chains & tokens in 2026

• BTC — highest brand trust, slowest UX (10-30 min confirms).
• ETH — mid-speed, gas fees still $2-$8 per deposit.
• USDT TRC-20 — the winner. Sub-second confirms, ~$1 fees, stable value.
• USDT ERC-20 / BEP-20 — for players already in the Ethereum/BNB ecosystem.
• SOL, LTC, TON, XRP — nice-to-haves for regional demand.

On-chain vs custodial wallets

Custodial (we hold keys) = instant UX, KYC required. Non-custodial (player holds keys) = maximum privacy but harder to run bonuses and RTP audits. Most 2026 operators run hybrid: custodial hot wallet + cold storage for reserves.
