Reducing custom contract logic for standard features.
Building contracts that auditors and protocol teams already recognize.
Generating templates with Contracts Wizard before customization.

Best fit:

teams building DeFi protocols, token systems, DAO tooling, NFT projects, and internal smart contract infrastructure.
