Includes support for:

• ERC-721 (NFTs)
• DAOs
• Staking contracts
• ERC-20 tokens
• Vault contracts

---

Features

• Modular design: each contract type is a separate module
• Uses ethers-rs for provider, signer, and contract bindings
• Works with any Ethereum-compatible chain (Mainnet, Goerli, Polygon, etc.)
• Includes usage examples and .env configuration
