Final Commit: 5a23518e934cae186c3929f5e5bb736e7e11b574 | Smart Contract | Critical |
We are looking for evidence and reasons for incorrect behavior of the smart contract, which could cause unintended functionality:
Clear wording:
Allocated bounty reward will be split between all researchers who submitted the same issue (where uniq issues receive 1/3 of the pool and researchers will get 1/9 each of the initial reward pool).
Full Reward: If a critical vulnerability is found by only one participant, that reporter receives 100% of the bounty pool.
If multiple participants find the same vulnerability, the allocated bounty for that issue (bounty pool always equally split among all unique issues reported) is divided equally among all reporters. Example: If two researchers report the same vulnerability, each receives 50% of the allocated bounty. It can be 50% of the bounty pool if only one eligible issue was reported.
Split Based on Uniqueness of issues reported:
Each will receive 50% of the bounty pool.
