Lesson 3 Decentralize Applications (DApps)

Using Web3

WARNING! Don't be a dummy like me and make sure you are using the correct version of web3. Check your package.json file and delete the caret "^" on web3 to prevent automatically updating to a newer version and breaking your DApp.

• Truffle can have its own web3 syntax. Use these docs. Upon Truffle version 5 release, it will use web3 1.0.0.
• For "web3": "0.2x.x" use these docs and assign variable directly
• For "web3": "1.0.0-beta.26" use these docs and use .then() callback promises

Diagnosing issues

• (coming soon) EthStats explorer

Security assessment

• Awesome list of security tools
• Decompiler and Security tool, Porosity

Wallet integration
