Client snapshot

A crypto-native operator launching a new casino brand targeting the global crypto-gambling audience, with an explicit commitment to provably fair gameplay and multi-chain support from launch. Founders came from a DeFi background rather than a traditional iGaming one. Brand name anonymized.

The challenge

The founders wanted three things that are individually hard and collectively hard to combine. They wanted on-chain provably fair verification that a technical player could actually run themselves, not a marketing label on a regular RNG. They wanted wallet UX that worked for both crypto-native players who would connect a self-custody wallet and casual depositors who wanted a custodial balance with no gas exposure. And they wanted the platform structured so that, when their licensing process completed, full KYC, source-of-funds checks and jurisdictional segmentation could be turned on without a rewrite.

They also wanted a meaningful library of licensed casino content alongside their own provably fair originals, which meant integrating a traditional aggregator into a crypto-first platform.

The approach

We built the platform in two layers. The on-chain layer handled provably fair verification: a commit-reveal scheme for in-house games, with seeds and outcomes anchored on chain and a verifier tool players could run from the public site. The off-chain layer handled licensed aggregator content, which by its nature is not on-chain provably fair but is RNG-certified by accredited labs.

The wallet was built dual-mode from the start. Casual players got a custodial balance with instant deposits and withdrawals. Crypto-native players got an optional self-custody mode where bets settled against an on-chain balance without the platform ever holding funds. Switching between modes was a single explicit player action with full disclosure on both sides.

The compliance scaffolding was in place from launch even though the operator's licence was still in process. KYC tier logic was implemented and dormant. Jurisdictional segmentation was implemented and configured permissively. When the licence came through, switching the posture was a configuration change rather than a build.

Tech stack

Front-end on a React stack with web3 wallet connectors for the major chains. Custodial wallet service in Go with hot/cold separation and multi-signature authorisation on the cold tier. On-chain integrations across Bitcoin, Ethereum and EVM L2s, Solana and Tron. Provably fair commit-reveal implemented in-house with public verifier code published alongside launch. Aggregator integration through a standard layer. KYC integration with a major identity vendor, dormant until activation.

Outcomes

The platform shipped on time. The provably fair verifier was published publicly and reproduced match outcomes deterministically against the public ledger. The multi-chain wallet handled deposits and withdrawals across all supported chains through launch. The platform scaled through its first major promotional weekend without wallet or settlement incidents. When the operator's licence finalised, KYC and jurisdictional posture activation went live on schedule.

Services used

Casino app development for the front-end and player experience, slot game development for the in-house provably fair originals, casino game aggregator API for the licensed third-party content, licensing and compliance for the dormant KYC scaffolding, and security audit and penetration testing on the wallet and on-chain integrations before launch.

If you are building or running a crypto casino and the gap between your provably fair marketing and your provably fair engineering is wider than you would like, this is the build to talk to Sudonex about.
