Lisk smart contracts

Verifiable, private, cross-chain payment infrastructure

A voting system implemented as a smart contract which allows users to propose options, vote on them within a specified time frame, and finalize results in a decentralized manner.

A simplified implementation of a smart contract proxy pattern in Solidity, based on EIP-1967. This project explores the concept of upgradable smart contracts using proxies, and includes a clear explanation, example code, and key considerations for implementing upgradeable logic safely.

A minimal Smart Wallet prototype in Solidity inspired by EIP-4337. Includes core features like owner management, secure execution, nonce handling, signature validation, and a Paymaster contract for gas sponsorship.Bonus features include ERC20 gas payments and batched transactions.

A lottery system where participants can enter the lottery by sending Ether and after a certain time period, a winner is randomly selected to receive the entire balance.

An NFT-gated Event Management System that allows users to create events and register for them, but only if they own a specific NFT.

A decentralized auction platform that allows users to create time-bound auctions, place bids, and automatically manages the auction lifecycle including bid placement, auction closing, and fund distribution.

A Solidity Smart Contract designed to manage student records on the Ethereum blockchain

Credible Crypto offers a groundbreaking solution for authentic and verifiable testimonials through blockchain technology. Winner of Lisk Onchain Spring Hackathon!

Multi-framework smart contract deployment using Hardhat and Foundry, showcasing cross-chain deployment of an Ownership contract on Lisk Sepolia (ETH gas) and Arc Testnet (USDC gas).
