⛓️ DanielGeek's Blockchain Projects

Welcome to my personal collection of blockchain development projects, featuring real-world dApps, smart contracts, DeFi tools, NFT marketplaces, staking platforms, and experiments with multiple chains including Ethereum, Solana, Polygon, BNB Chain, and Tezos.

This repository is a showcase of hands-on experience using Solidity, Rust, Foundry, Hardhat, Anchor, and frontend frameworks such as React, Next.js, and SvelteKit.
