6. Infrastructure tooling

Composability is one of the key design principles of DeFi protocols, which means that different components of a system can readily connect and communicate with one another. Here, many people compare DeFi development to building with legos, earning the moniker "money legos" in the process.

Also, Ethereum developers and product teams can now build and launch DeFi protocols with the full-stack tooling and security integrations they require, thanks to Truffle's smart contract libraries, Infura's API suite, and Diligence's security tools.
