Timba
On-chain gaming platform built from scratch with the founder.
Problem
The founder had the idea: a gaming platform where people play coinflip and giveaways with real money on Telegram. He knew the market, knew the players, but didn't know how to build it. He needed someone who could turn the idea into a product: games, wallets, deposits, the bot, the fairness system, the landing page.
Solution
I built it. Smart contracts on Solana for coinflip, giveaways, and a game type called snowball. A Telegram bot where you create games, join games, tip people, and withdraw, all without leaving the chat. A provably fair system so anyone can verify the result of any game on-chain. And a landing page with a game verifier where you paste a transaction and see exactly how the winner was decided.
How
Solana + Anchor (Rust) for contracts. TypeScript + Bun for the Telegram bot. Next.js on Cloudflare Workers for the web. The fairness system uses a commit-reveal scheme: the game creator commits a hash, the Solana slot number gets recorded, and the result is secret XOR slot. The oracle reveals the secret after a buffer so nobody can cheat.
Outcome
A real product running on Solana mainnet. People play, win, and can verify every result. The founder got from idea to launch.
