Terms of use

The tools

CryptoAPIs provides free developer tools that run in your browser. They are provided as-is, without warranty. Results describe the data you supplied under the named profile and reference packs; they are not a statement about current network state.

No advice

Nothing on this site is financial, investment, legal or tax advice. A decoded function name, a valid checksum or a successful receipt status does not mean a contract, address or transaction is safe, legitimate or final.

No custody

The site has no wallet, signing, trading or broadcast features and never asks for private keys or seed phrases.

Your responsibility

Review generated snippets and redacted output before using or sharing them. Keep your own backups: browser storage can be cleared or evicted.
