Bounty Eligibility

Lambda encourages the community to disclose wallet security vulnerabilities, and to play a role in building Lambda ecosystem, thereby receiving USDT bounties as reward. However, final rewards are determined at the sole discretion of the Lambda Technical Committee.

Let’s learn more about the bounty now!

According to the severity calculated by OWASP Risk Rating Method based on Impact and Likelihood.


  • High: Bugs affecting asset security.
  • Medium: Bugs affecting system stability.
  • Low: Other bugs that do not affect asset security and do not affect system stability.


  • High: The bug can be discovered by anyone who performs an operation, regardless of whether or not the bug has been found.
  • Medium: Only certain people can discover it (such as a bug that only developers encounter, ordinary users are not affected.)
  • Low: Covers less than 1% specific population, such as certain rare Android models; or any other exceptional cases.

The Amount of Rewards

To ensure the bug reporter obtains a stable expected reward, USDT will be the main crypto as rewards.

The reward amount is divided into 5 categories:

  • Critical: 1,000 + USDT (No upper limit)
  • High: 500 + USDT
  • Medium: 200 + USDT
  • Low: 50 + USDT
  • Note: 30 + USDT

If reporters provide the solution of security vulnerabilities, the reward will be more than doubled.

Bounty Judges

Judges are from Lambda Technical Committee.

Report A Bug

Please send bug report via the google form here.


1. Please ensure the accuracy and clarity of the content, because the reward evaluation will be based on the content submitted in this form.

2. If many people discover the same bug, then their report submissions in chronological order will determine their reward. Community users are welcome to discuss the issues of bugs, but the discussion itself is not considered a report, therefore a report form must still be submitted.

The Final reward list announcement

After the bounty program, the final reward list and the reward amount will be announced on Twitter and Weibo channel, and rewards will be issued within 15 working days.
