BuildsWithKing

One Smart Contract Every Day – From Zero to Smart Contract Hero. This repository contains my daily smart contract builds as part of my 30-Day Solidity Challenge. Each folder represents a new day, a new project, and a step forward in mastering Solidity.

A decentralized, provably fair lottery system built with Solidity and Foundry, leveraging Chainlink VRF for verifiable randomness and Chainlink Automation for automated winner selection.

A soulbound NFT launch system that gates access based on onchain reputation scores from Ethos Network. Users with verified reputation can mint non-transferable NFTs and claim tiered token rewards - creating fair, bot-resistant launches for Web3 communities.

This repository contains the advanced phase of my 30-day Solidity mastery challenge — Days 21–30. Focus: Refactor previous projects, write Foundry tests, deploy smart contracts to Sepolia Testnet, and verify functionality.

A modern, responsive web application for interacting with the KingYieldAggregator smart contract system - an automated yield aggregator that maximizes returns by dynamically allocating funds across multiple DeFi strategies.

This repository contains my beginner-to-intermediate Solidity smart contract projects built using Foundry. Each project is designed to reinforce core Solidity concepts like mappings, structs, custom errors, events, receive/fallback functions, and ETH transactions.
