Question: Is there a tool that helps me understand and analyze smart contract code with syntax highlighting?

If you want a tool to read and debug smart contract code with syntax highlighting, ContractReader is a great option. It supports multiple networks, has syntax highlighting, testnet support, live on-chain values, in-browser code comparison, and GPT-4 security reviews. The tool is geared for developers and companies that manage smart contracts, letting them easily review and manage code.

Another option is Metabob, an AI-powered coding assistant that uses graph-attention networks and generative AI to help with code review, refactoring and debugging. Although it's geared more toward software security and quality improvements, its AI abilities can also be used to analyze and understand complex smart contract code problems. It offers AI code review, software security scanning and debug and refactor services, making it a good option for maintaining and verifying smart contract code.

For a no-code approach, Toolblox offers a visual interface for defining the lifecycle of assets and services, a Contract Maker for building smart contracts, and a DApp Maker for building decentralized applications. The platform lets founders, agencies and businesses rapidly create MVPs and prototypes, visualize smart contracts and bring liquidity to business ideas. It can be used for supply chain management and real estate tokenization, among other use cases.
