When to use this in your project

Speeding up your workflow
Generate boilerplate you would normally write by hand in seconds, reducing time spent on repetitive configuration.

Learning by example
The output doubles as a reference for the format — study it to understand the underlying tool, protocol, or config schema.

Developer notes

!Never paste real private keys anywhere — this tool does not ask for them and nothing ever should.
!Ethereum addresses are case-insensitive but EIP-55 mixed-case checksum encoding encodes error detection.
!Always test on a testnet (Sepolia) before mainnet — blockchain transactions are irreversible.

Privacy & Security

All Dev-Belt tools run 100% in your browser using client-side JavaScript. Your input data is never sent to our servers, never logged, and never stored. This includes code snippets, credentials, tokens, API keys, and any other sensitive information you enter.
