Lotshot introduces the world’s first fully transparent and instant NFT lottery, where every ticket is an NFT and fairness is guaranteed by blockchain technology. Using Polygon and TON smart contracts, the entire process — ticket minting, randomization, and prize payouts — becomes fully automated and protected from manipulation.

Case Story

Vlad M

CMO at Lotshot

The product must be a fully on-chain NFT-based lottery platform built on the TON blockchain, enabling users to connect their TON wallets, purchase NFT tickets for lottery rounds, and participate in provably fair draws executed entirely through smart contracts, with automated winner selection and instant payout distribution; the solution should include secure and modular smart contract architecture for round management, NFT minting logic, verifiable randomness generation, treasury and fee allocation mechanisms, and a user-friendly Web3 frontend optimized for seamless wallet interaction and compatibility with the Telegram ecosystem.

Yurii Bulakh

CTO at Tetracode

Tetracode has the technical expertise to design and deliver a fully on-chain NFT-based lottery platform on TON, including smart contract architecture for round management, NFT ticket minting, provably fair randomness logic, automated winner selection and payouts, treasury mechanics, and seamless TON wallet integration; we would implement a modular, audit-ready contract structure optimized for scalability and security, accompanied by a clean Web3 frontend (with potential Telegram Mini App expansion).

Our Solution - transparent Web3 lottery powered by instant blockchain mechanics

Smart Contract Architecture

Tetracode designed a modular smart contract architecture on TON with isolated management of each lottery round, implemented full on-chain NFT ticket minting, developed a provably fair randomness algorithm based on blockchain entropy, and deployed fully automated winner selection and payout distribution without any manual intervention.

Security, Transparency & Treasury Model

We implemented a secure contract state transition model minimizing manipulation vectors, automated fee distribution and treasury management, ensured full on-chain transparency with verifiable draw results, and structured the contracts to be audit-ready and scalable for future expansion.

Web3 Interface, TMA, TON Ecosystem Integration

We developed a fully functional Telegram Mini App (TMA) with seamless TON wallet integration, enabling users to participate directly within Telegram, view NFT tickets, track live round statuses and results in real time, and interact with a Web3 frontend fully compatible with the TON ecosystem.
