Solidity Learning Repository

A collection of Solidity examples and Ethereum smart contracts for learning and experimentation.

Cleanup applied

This repository was reorganized to make the examples easier to navigate and maintain:

• Added a contracts/ directory with topic-based subfolders.
• Renamed files to use descriptive names and .sol extensions.
• Kept source content intact so examples can still be reviewed as originally written.

Repository layout

  auctions/
    SealedBidAuctionFinal.sol
    SealedBidAuctionUpdated.sol
    SimpleAuctionAdvanced.sol
    SimpleAuctionBase.sol
  examples/
    HelloWorld.sol
  tokens/
    ERC721.sol
    SimpleToken.sol

Suggested next cleanup steps

1. Fix Solidity syntax errors and typos in the auction/token examples.
2. Add a Solidity toolchain (foundry or hardhat) and CI checks.
3. Add one README per folder documenting learning goals and known limitations.
