SynLev Bug Bounty

Earn up to $3,000 (60,000 SYN) for finding bugs in the latest SynLev contracts. If you are not yet familiar with SynLev project check out our intro article, litepaper, and dApp beta walkthrough. We have been hard at work testing and developing the core SynLev contracts and dApp. We are happy to report that our Kovan testnet contracts have been published and running for the past week without any major issues. And we are now ready to open public bug bounties.

Bug Definition

Bugs are defined as any exploit on the SynLev core contracts that result in unexpected errors/behavior, illegitimate withdraw of funds, draining of contract funds, manipulation of price data, etc… Gas savings may also be considered as a low level bug for the purposes of this bounty.

Scope of Bugs

Any of the core SynLev core contracts and their corresponding Kovan addresses listed at testnetaddress.json. Be sure to check our github while working as contracts will be continuously updated. Bugs related to javascript or the SynLev beta dApp are not in the scope of this bug bounty and will not be accepted.

Reward Tiers

Discovered bugs will be rewarded based on their severity and determined by the following criteria:

  • Effects of the exploit (e.g. ranging from failed transactions to illegitimately withdrawing funds from the contract)
  • Repeatability of the exploit
  • Complexity of exploit
Bug bounty reward tiers

In addition bonuses may also be awarded based on factors such as the number of instances the bug exists in the code, submitted documentation, amount of research done by submitter, and if a solution or code fixing the bug is submitted.
