These are testnet learning examples. The single most important rule:

Never use a real seed phrase, private key, or mainnet address with this code.

Every key in this repo is a disposable testnet key. Testnet coins have no value, so there is nothing to steal, and that is the point. If a recipe ever seems to ask you for a real key, stop: something is wrong.

If you find a security issue in a recipe, for example something that could leak a key or nudge someone toward using a real one, please report it privately:

• Use GitHub's "Report a vulnerability" under the repository's Security tab, or
• Email hello@tech1k.com

Please do not open a public issue for a security report.
