On chain gaming infrastructure.
Gatekick Labs builds the full stack for crypto gaming platforms. Provably fair game mechanics, crypto deposit and withdrawal flows, liquidity provider integration, stablecoin settlement, operator dashboards, and compliance tooling. Everything an operator needs to run a platform that players trust and regulators accept.
What we build.
Running a crypto gaming platform means solving problems across randomness, payments, wallets, compliance, and operations simultaneously. These are the systems we build most often, and the areas where our experience is deepest.
Provably Fair Game Contracts
We build game contracts where every outcome is cryptographically verifiable. Players can independently confirm that dice rolls, slot spins, roulette results, crash multipliers, and plinko paths were generated fairly. We integrate VRF for decentralized randomness and design commit reveal schemes where oracle costs need to stay low.
- Chainlink VRF integration for auditable on chain randomness
- Commit reveal schemes for cost sensitive high frequency games
- On chain outcome anchoring so every result is permanently verifiable
- Game specific logic for dice, slots, roulette, crash, and plinko
Crypto Payment Integration
We build the deposit and withdrawal infrastructure that connects players to your platform. USDC and EURC stablecoin rails for instant settlement, BTC and ETH support for players who prefer native assets, and multi chain architecture so deposits arrive on the cheapest and fastest network available.
- USDC and EURC deposit and withdrawal flows with instant finality
- BTC, ETH, and SOL acceptance with automatic conversion to stablecoins
- Multi chain support across Ethereum, Solana, Base, Arbitrum, and Polygon
- Fee optimization through batched withdrawals and gas sponsorship
Liquidity Provider Integration
We connect your platform to liquidity aggregators and OTC desks so players can move between crypto and fiat without friction. This means integrating with on ramp and off ramp providers, accessing deep order books for large conversions, and managing slippage so operators keep their margins predictable.
- Connections to aggregated liquidity for fiat to crypto conversion
- On ramp provider integration for card and bank deposits
- Off ramp rails for fiat withdrawals through licensed payment partners
- Slippage management and spread optimization for large volume flows
House Wallet and Treasury
We design the wallet architecture operators use to manage bankroll, absorb variance, distribute profits, and maintain solvency. Multisig controls protect reserves. Automated rebalancing keeps funds distributed correctly across hot and cold storage. Real time monitoring alerts operators before reserves hit dangerous thresholds.
- Operator controlled multisig wallets with role based access
- Automated profit distribution and reserve rebalancing
- Bankroll monitoring with configurable threshold alerts
- Proof of reserves mechanisms players can verify independently
Player Wallet Infrastructure
We build the wallet layer that sits between players and the blockchain. Custodial wallets for operators who want full control over the player experience. Non custodial options for platforms targeting crypto native users. Session wallets that let players approve a spending limit once and play without signing every transaction.
- Custodial wallet systems with internal ledger and instant settlement
- Non custodial wallet connections via WalletConnect and browser wallets
- Session wallets with pre approved spending limits for seamless gameplay
- Gasless transactions through relayer networks and account abstraction
Settlement and Reconciliation
We build the systems that keep game engine balances, blockchain state, and operator records perfectly aligned. Every game round settles to a verifiable on chain record. Deposits and withdrawals reconcile automatically. When transactions get stuck or chains congest, retry logic and fallback paths keep the platform running.
- Real time balance tracking across game engine and blockchain layers
- Automated reconciliation between internal ledger and on chain state
- Stuck transaction detection with automated retry and escalation
- Dispute resolution workflows with immutable audit trails
Compliance and KYC Integration
We integrate the compliance infrastructure that licensed operators need to serve regulated markets. Age verification, identity checks, jurisdiction blocking, transaction monitoring, and regulatory reporting. For operators adding crypto to an existing licensed platform, we build the compliance layer so crypto rails meet the same standards as fiat.
- KYC provider integration for identity and age verification
- Jurisdiction detection and geo blocking for restricted markets
- AML transaction monitoring with suspicious activity flagging
- Regulatory reporting exports for licensed gaming jurisdictions
Prediction Markets and Sports Betting
We build outcome markets for sports, esports, and real world events. Binary and multi outcome structures, odds engine integration, oracle based event resolution, and position management. The settlement logic handles edge cases that break simpler implementations, including cancelled events, disputed outcomes, and partial resolutions.
- Binary and multi outcome market contracts with flexible resolution
- Odds engine integration with real time line movement
- Oracle based event resolution with fallback and dispute mechanisms
- Position management with early cashout and partial settlement
The types of platforms we build.
These scenarios reflect the types of gaming engagements we take on. Each one requires solving problems across payments, fairness, operations, and compliance simultaneously.
Crypto casino with instant stablecoin payouts
An operator launching a new crypto casino needed provably fair games and instant withdrawals. This requires game contracts with VRF integration across multiple game types, a stablecoin settlement layer for USDC and EURC payouts, and a house wallet system the treasury team can manage without touching private keys directly. Players withdraw winnings in seconds. Every game outcome is anchored on chain and independently verifiable.
Sports betting platform with liquidity provider integration
A sports betting operator wanted to accept crypto deposits and offer fiat withdrawals through licensed payment partners. We integrated multiple liquidity providers for instant crypto to fiat conversion, built the settlement pipeline so winning bets paid out within minutes regardless of the player's preferred currency, and connected oracle feeds for automated event resolution across major sports leagues.
Play to earn gaming platform
A gaming studio building a play to earn ecosystem needed on chain game state, token rewards for player achievements, and NFT items that players could trade on secondary markets. This requires smart contracts for the reward distribution system, token economics designed to sustain long term engagement without hyperinflation, and marketplace contracts so in game items have real liquidity from day one.
Regulated iGaming operator adding crypto
An established iGaming operator with existing fiat payment rails and a gaming license wanted to add crypto deposits and withdrawals without jeopardizing their regulatory standing. This requires a compliance first integration that layers stablecoin rails alongside existing PSP connections, adds KYC verification for crypto wallets, implements AML transaction monitoring, and produces the reporting exports the regulator requires. Crypto becomes another payment method, not a separate system.
Prediction market for esports
A team building a prediction market focused on competitive gaming events needed binary outcome contracts, real time odds updates, and oracle based resolution tied to match results from official tournament APIs. This requires carefully designed market mechanics, settlement contracts with dispute resolution for contested outcomes, and stablecoin deposits so players can fund positions without holding volatile assets.
The payment layer that makes everything work.
A gaming platform lives or dies on how smoothly money moves in and out. Deposits need to be instant. Withdrawals need to be fast and cheap. Everything in between needs to reconcile perfectly. This is the infrastructure we build.
Deposit Flows
A player sends USDC, EURC, ETH, BTC, or SOL to a deposit address or connects their wallet directly. The system detects the incoming transaction, confirms it on chain, converts non stablecoin assets to the platform's base currency if needed, and credits the player's internal balance. For fiat deposits, we integrate on ramp providers so players can buy crypto with a card or bank transfer and have a playable balance within minutes.
We handle the edge cases that break simpler implementations. Deposits sent on the wrong chain. Partial confirmations during network congestion. Tokens sent to the wrong address type. Underpayments and overpayments. Each of these has a defined resolution path so the player is never left waiting without information.
Withdrawal Flows
When a player requests a withdrawal, the system validates the amount against their verified balance, applies any compliance checks, selects the optimal chain for cost and speed, and executes the on chain transfer. For USDC and EURC withdrawals, settlement is typically under a minute. For players who want fiat, we route through integrated off ramp providers that convert stablecoins to local currency and send to the player's bank account.
Withdrawal batching reduces costs for the operator. Instead of executing individual transactions, the system groups withdrawals within a short window and processes them together. This cuts gas costs significantly on high volume platforms without adding meaningful delay for players.
Liquidity Provider Architecture
We integrate with liquidity providers, on ramp services, and OTC desks to give operators access to deep liquidity for currency conversion. This means connecting to aggregated order books for competitive rates, routing through multiple providers to minimize slippage on large transactions, and maintaining fallback paths so a single provider outage never blocks player withdrawals.
For operators serving multiple regions, we build FX conversion pipelines that handle the path from a player's local currency to crypto and back. A player in Europe deposits EUR via bank transfer, plays in USDC, wins, and withdraws back to EUR. Each step in that flow needs a liquidity provider, a rate quote, and settlement confirmation. We build the orchestration layer that makes it seamless.
Multi Currency Support
We build platforms that handle BTC, ETH, SOL, USDC, EURC, and local fiat currencies simultaneously. Internally, the platform operates on a base stablecoin for consistency. All other currencies are converted at deposit and reconverted at withdrawal. This means the game engine only needs to track one balance per player while the payment layer handles the complexity of multi currency support.
Rate management is critical. We integrate real time price feeds, apply configurable spread markups for the operator, and lock rates at the moment of conversion so neither the player nor the operator is exposed to price movement during the transaction window.
Fee Optimization
Gas costs eat into margins on high volume platforms. We minimize this through chain selection, batching, gas sponsorship, and smart routing. Deposits and withdrawals are routed to the cheapest chain that meets the speed requirement. Withdrawal batching groups multiple payouts into single transactions. For platforms that want to absorb gas costs entirely, we build relayer infrastructure that sponsors transactions on behalf of players.
We also optimize the operator's treasury operations. Reserve movements between hot and cold wallets, profit distributions, and liquidity rebalancing are all scheduled during low congestion periods and batched where possible.
Reconciliation
Every on chain transaction must match an internal ledger entry. Every game round outcome must reconcile to a balance change. Every deposit and withdrawal must trace from the player's action through the blockchain to the operator's records. We build automated reconciliation that runs continuously, flags discrepancies immediately, and provides the audit trail operators need for financial reporting and regulatory compliance.
When things go wrong, and on blockchain systems they will, the reconciliation layer catches it. Stuck transactions trigger automated retries with escalating gas prices. Failed conversions route to fallback liquidity providers. Discrepancies between the game engine and blockchain state generate alerts with enough context for the operations team to resolve them quickly.
Randomness players can verify.
Provably fair gaming is the reason players choose on chain platforms over traditional casinos. If the randomness is not genuinely verifiable, you have lost the only advantage that matters. We build systems where fairness is a mathematical guarantee, not a marketing claim.
VRF Implementations
Verifiable Random Functions produce randomness that is provably unbiased and tamper proof. We integrate Chainlink VRF on EVM chains and equivalent oracle services on Solana to generate random values that neither the player nor the operator can predict or manipulate. Each random value comes with a cryptographic proof that anyone can verify on chain.
VRF is the gold standard for high stakes games where the cost of the oracle call is justified by the bet size. We design the callback architecture so game settlement happens atomically with the randomness delivery, eliminating any window where outcomes could be front run or manipulated.
Commit Reveal Schemes
For high frequency, low stakes games where VRF oracle costs would eat into margins, we design commit reveal schemes. The operator commits to a secret value before the player acts. The player makes their choice. The secret is revealed and combined with the player's input to produce the outcome. Both parties can verify that neither side cheated.
- Operator commits a hashed secret before each round
- Player action is recorded on chain before reveal
- Combined seed produces the game outcome deterministically
- Any deviation from the committed value is detectable and provable
On Chain Outcome Anchoring
Every game result is written to the blockchain as a permanent, immutable record. This means outcomes cannot be altered after the fact, players can look up any historical result, and third party auditors can verify the statistical distribution of outcomes over time. We design the data structures so anchoring is gas efficient while still containing enough information for full verification.
For platforms that run thousands of game rounds per hour, we use Merkle tree based batching to anchor large volumes of outcomes in a single transaction while maintaining individual verifiability for each round.
Player Verification and House Edge Transparency
We build the tools that let players verify fairness themselves. A verification page where any player can input a game round ID and see the seed, the randomness proof, and the mathematical derivation of the outcome. We also make the house edge transparent and on chain, so players can confirm that the probability distributions match what the platform claims.
- Player facing verification interface for any game round
- Published house edge parameters readable from the smart contract
- Statistical analysis tools showing actual outcome distributions
- Open source verification scripts players can run independently
Everything behind the scenes.
Provably fair games and smooth payments are what players see. Behind them is a layer of operator tooling that keeps the platform profitable, secure, and compliant. We build both sides.
Admin Dashboards and Monitoring
We build the dashboards operators use to run their platform daily. Real time views of active players, game volume, deposit and withdrawal queues, treasury balances, and system health. Alerts fire when withdrawal queues back up, when gas prices spike above thresholds, when player balances show unusual patterns, or when any blockchain RPC connection degrades.
Operators see everything that matters on a single screen. Game round outcomes, payment processing status, compliance flags, and system uptime. When something needs attention, the dashboard tells them what happened, when it happened, and what to do about it.
Risk Management and Fraud Detection
We build fraud detection systems that catch collusion, bonus abuse, multi accounting, and suspicious betting patterns before they damage the bankroll. Pattern recognition identifies coordinated play across linked accounts. Velocity checks flag rapid deposits followed by single large bets. Behavioral analysis detects when a player's pattern shifts in ways that suggest bot activity or account takeover.
Risk management also means managing the house's exposure. We build systems that track real time risk across all active games, calculate maximum possible payouts against current reserves, and automatically adjust bet limits when variance pushes the bankroll toward configured thresholds.
Player Analytics
We build the analytics layer that turns raw game data into operational intelligence. Player lifetime value, retention cohorts, game preferences, deposit patterns, and churn indicators. Operators use this to understand which games drive engagement, which acquisition channels produce valuable players, and where the platform loses people in the conversion funnel.
Regulatory Reporting
Licensed operators need structured data exports for their regulators. We build the reporting pipelines that produce the required formats. Player activity reports, financial summaries, responsible gaming metrics, suspicious transaction reports, and whatever else the licensing jurisdiction demands. Reports generate automatically on schedule and are available on demand for ad hoc regulatory inquiries.
Treasury Management and Bankroll Alerts
We build treasury management systems that give operators full visibility and control over their funds. Hot wallet balances, cold storage reserves, pending withdrawals, and projected cash flow. Automated rebalancing moves funds between hot and cold storage based on configurable rules. Bankroll alerts notify the treasury team when reserves approach minimum thresholds, when a single session produces outsized wins, or when withdrawal volume spikes unexpectedly.
Profit distribution happens automatically according to rules the operator defines. Revenue splits between stakeholders, reserve allocations, and reinvestment pools all execute on schedule without manual intervention.
