Data handling

  • Since Engine is self-hosted, you (the developer) maintain control over the server, database, logging, and observability.
  • Engine handles configuration data encrypted in transit and at rest.
  • Backend wallet signers are reconstructed only in memory on your Engine instance, and this data is never sent to thirdweb or other external platforms.
  • thirdweb may collect the following information:
    • Metrics on which accounts are using Engine
    • Anonymized metrics on usage
    • Transactions history
    • (TBD future data to power advanced analytics)

Third-party security audit

As of Jan 2024, Engine has received a thorough security audit and internal bug bounty program from HackerOne. A Letter of Attestation may be provided upon request.
