Crypto casino infrastructure, custody included
Native on-chain custody rather than a payment widget — HD deposit addresses, automatic sweeping, sponsored gas, HSM/KMS key management, and continuous solvency verification against player obligations.
Accepting crypto is easy. Holding it is the hard part.
Taking a stablecoin deposit is a solved problem — plenty of widgets will do it. What follows is the part that sinks crypto casinos: you are now holding bearer assets for thousands of people, across several chains, and every one of those balances is a liability you must be able to cover on demand.
That means key management that survives an employee leaving, sweeping that does not strand funds in dust, gas that does not become a per-transaction tax on your margin, and — critically — a way to demonstrate at any moment that on-chain holdings cover what players are owed.
Slotty Labs builds custody as first-class infrastructure rather than bolting a processor onto a fiat platform.
- HD deposit addresses derived per player, per chain.
- Automatic sweeping into managed storage with dust handling.
- Sponsored gas with per-tenant budgets and spend controls.
- HSM / KMS key management — keys are never handled as loose material.
- Cold-storage multisig for reserves.
- Continuous solvency verification — on-chain holdings checked against player obligations per currency and tenant.
A ledger that cannot drift
Crypto balances still have to reconcile to an internal book. The wallet is double-entry with a cryptographic hash chain over its history — tamper-evident by construction, and verifiable without trusting the operator.
Integer-only money math
All monetary computation is BigInt arithmetic in minor units. No floating point exists anywhere in the money path, so rounding drift cannot accumulate.
Negative balances are impossible
Pessimistic balance locking enforced at both application and database level, so a race condition cannot overdraw an account.
Idempotency on every money operation
Network retries can never double-charge or double-credit — the same operation key resolves to the same single posting.
Daily reconciliation
Automated checks of the ledger against cached balances and, for crypto, against on-chain reality — with exportable reports.
Real, bonus and locked balances separated
Wagering-requirement tracking is built in, and withdrawal requests ledger-lock the funds at the moment they are raised.
Hash-chained history
Every posting extends a cryptographic chain, so any retroactive edit to the books is detectable.
Chains and tokens
Withdrawals are fast and operator-controlled — approval workflow, pre-flight checks, broadcast monitoring and stuck-transaction handling included.

Crypto-native players, crypto-native games
Provably fair on every round
SHA-256 commit-reveal with a public verification page. The audience that asks for an on-chain casino is usually asking for exactly this — verifiable outcomes, not a smart contract for its own sake.
Instant-game formats that convert
A crash game, one-strike instant games, cash-out games where the player decides when to stop, a pick-and-cash-out party game, a multiplier ladder, a multiplier walk and a risk-tier launcher: the formats crypto lobbies actually run, all original and all first-party.
Zero aggregator revenue share
The sixteen titles are Slotty Labs originals, so rounds played on them do not carry a third-party aggregator's cut.
