The job

  • One actor farms a launch, a vote or a reward pool with hundreds of accounts.
  • The obvious fix is to collect ID from everyone, which makes you the breach.
  • Blocking by wallet age or gas history punishes real newcomers first.

How it works.

  1. 01

    Combine account signals

    Passport Stamps combine verifications into a score you can use in your application.

  2. 02

    Choose your threshold

    Balance the risk of duplicate participation with the effort you ask of legitimate users.

  3. 03

    Apply the result

    Read the score and credential status before granting access or allocating rewards.
