Web3 Casino Games

Built smart contracts and dapps for web3 casino games. Implemented casino logic(bets, payouts, jackpots) on-chain and ensuring fairness with provably fair algorithms. Handled deposits, withdrawals, and staking. Integrated NFTs for in-game assets, VIP access, or player rewards.

Provably Fair

Smart Contracts

Status: Active

Project Overview

A full Web3 casino game engine with on-chain logic for bets, payouts, and jackpots. Every outcome is verifiable: RNG is sourced from verifiable randomness so players can audit fairness without trusting the operator.

I built the smart contracts in Rust (Solana) and Solidity (EVM), covering deposits, withdrawals, staking, VIP-tier NFTs, and treasury / fee logic. The frontend is Next.js + TailwindCSS with a Prisma/PostgreSQL backend for user accounts and session history.

Technical Implementation

Architecture

A modular architecture cleanly separating on-chain programs, low-latency data ingestion, and the user-facing app. On-chain code is written in Rust or Solidity with strict test coverage; off-chain services run on Node.js / Rust backends with Redis and PostgreSQL for hot and durable state respectively, containerized for reproducible deploys.

Smart Contracts

Programs are implemented in Rust with the Anchor framework on Solana, or in Solidity on EVM chains, with strict access control, exhaustive error handling, and gas / compute-unit optimization. Every state transition is covered by unit and integration tests before mainnet deployment.

Performance & Reliability

Where the project is performance-sensitive, the hot path is optimized end-to-end: zero-copy parsing, connection pooling, Redis-backed caches, Jito / Nozomi inclusion for Solana, and careful batching for EVM. Monitoring and alerts cover latency, inclusion rate, and PnL so regressions surface immediately.
