Trust is the moat in crypto gaming. Players can't see your RNG — but they can verify it. Provably-fair systems turn transparency into a product advantage.

The provably-fair primitive

Server seed hash published before the round. Client seed contributed by the player. Final result derived deterministically. Publish the server seed after the round closes — anyone can verify.

• HMAC-SHA256 seeded combined server + client randomness
• Seed rotation logs published on-chain for auditability
• Open-source verifier players can run themselves
• Round-level receipts signed by the house wallet

Wallets that feel like banking

Non-custodial is purity. Custodial is practical. Most winning platforms run hybrid: a hot wallet for gameplay, cold storage for reserves, and one-click withdrawals players can trust.

Compliance still applies

Crypto doesn't exempt you from KYC, AML, or geographic rules. Build compliance in from line one — not as a retrofit after your first regulator letter.
