Crypto casinos

Full-stack crypto casino platforms

We engineer the full vertical: node-indexed deposits, treasury policy, provably fair game math, provider rails, and the player UI that has to feel instant under load. If it touches custody, odds, or settlement, we have shipped it at production scale.

What we deliver

Multi-Chain Wallet Architecture

Hot and cold wallet separation with policy-driven sweep rules, custodial and non-custodial onboarding paths, and chain-specific confirmation depth tables for BTC, ETH, LTC, USDT (TRC20/ERC20), USDC, SOL, and TRX. Ledger logic covers pending holds, partial confirmations, reconciliation against node and indexer truth, and batch settlement with idempotent payout jobs.

Provably Fair Engine

HMAC-SHA256 commit–reveal–verify: hashed server seed published before play, client seed and nonce per round, deterministic byte stream exposed for third-party audit. Game-specific mapping includes dice (52-bit slice → 0–99.999), crash (inverse-CDF sampling from a geometric / exponential parameterization you publish), and keno (weighted draws with rejection sampling so selections stay unique without bias).

Game Aggregation Layer

Middleware that normalizes provider callbacks (SOAP/JSON-RPC/WebSocket) into one internal event schema: authenticate, launch, debit, credit, rollback, and round close. Adapter pattern so a new studio ships as config + signing keys + mapping tables, not a greenfield integration. Idempotency keys on every provider call to survive retries.

KYC/AML Compliance

Document and liveness vendors wired into stateful workflows, transaction monitoring with rule packs and typologies, FATF Travel Rule messaging where VASPs are involved, geo-IP plus device signals for fencing, self-exclusion and cool-off timers, and immutable audit trails for regulators and acquirers.

Bonus & Promotion Engine

Deposit match with clawback on early withdrawal, cashback and rakeback accrual from settled handle, free-spin bundles with per-game caps, VIP ladders with rolling windows, wagering math that respects game weightings, scheduled tournaments with Redis-backed leaderboards, and segmentation fed by ClickHouse or warehouse syncs.

Admin Dashboard

Player 360 with notes and limits, real-time GGR and cohort views, automated risk scores and manual review queues, withdrawal approval tiers, RBAC with field-level policies, month-close exports, and live toggles for RTP bands and feature flags per jurisdiction.

How it works

01 — Ingest

Wallet & ledger first

Chain listeners write to an append-only ledger with double-entry semantics. Every credit has a matching liability row; sweeps and gas refills are modeled as internal transfers with approval workflows. We never mutate balances in place without an auditable journal entry.

02 — Play

Authoritative game server

Bets are reserved in the ledger, outcomes computed on the server from the committed PRNG stream, then settled atomically with provider debits/credits where applicable. Client prediction is cosmetic only; reconciliation jobs heal any drift from network partitions.

03 — Observe

Compliance & analytics

Every state change emits a typed event to Kafka. AML rules consume velocity and structuring patterns; BI pipelines land in columnar storage for cohort and LTV modeling. Withdrawals enqueue into risk tiers with SLA timers your ops team can see in the admin surface.

Technical depth

  • Game state sync under 150ms round-trip (edge-aligned WebSocket + authoritative server ticks).
  • Redis-backed session storage and leaderboard sorted sets (ZADD/ZRANGE) with TTL and shard-by-player for hot paths.
  • PostgreSQL with pgBouncer in transaction mode, partitioned ledger tables, and async logical replication to read replicas for reporting.
  • Kafka (or Redpanda) event bus ingesting 10,000+ events per second: bets, settlements, wallet movements, and compliance signals with exactly-once semantics at the consumer.
  • WebSocket clusters for multiplayer tables and crash multiplier streams, with sticky sessions and backpressure-aware fan-out.
