The house
always settles.
68 provably-fair titles over one wallet integration, delivered on REST + gRPC with a sub-3ms settle. Your platform holds every balance; we return the RNG, the payout and the audit trail.
Provably fair, publicly
Every outcome is HMAC-SHA256(server_seed, client_seed:nonce), committed before play, verifiable at a public endpoint — no account.
Sub-3ms atomic settle
A full round-trip — debit, play, settle — lands under 3ms including both wallet ops. Pure-Go engine.
Your wallet, zero custody
We never hold balances. GetTransaction reconciles; Atomic SettleBet debits + credits in one call.
Dynamic RTP, per launch
Set RTP 85–99% at game-init, snapshotted into every round, deterministic, never over 100%.
GGR analytics built in
Per-round GGR by game, currency, site & environment, round forensics and real-time network health.
