Contribution checklist

  • Public HTTPS endpoint (no API key)
  • Returns the correct chain ID
  • One chain per file

Never submit secrets. API keys, tokens, private endpoints, seed phrases, and wallet credentials do not belong in a public registry.

Example

Keep records minimal

Only include data that can be verified by anyone.
