Bug Bounty Program of Hakka Finance

Help us find any bugs or vulnerabilities and improve our wonderful ecosystem


Welcome to Hakka Finance’s Bug Bounty Program. Every day, we develop new ways to ensure safety and security with the best product possible. We are calling on our community to help us find any bugs or vulnerabilities. This helps maintain and improve our wonderful ecosystem.

Submit a bug here and earn a reward of up to 16,000 USD worth of HAKKA. Please see our Bounty Table & Rules section for more details.

Bounty Table

Please use this structured bounty table for general guidance. All final decisions are at the discretion of the Core Hakka Team. There are three different phases of Hakka Finance’s smart contracts: Production Phase / Staging Phase / Draft Phase.

Production phase refers to the operating smart contracts of Hakka Finance’s official products/platforms. Following table is the bug bounty of production phase:

Bounty of Production Phase Bugs

Staging phase refers to the alpha version or pre-launch stage’s smart contracts. There will be some deductions for the bounty of bugs discovered in the staging phase.

Bounty of Staging Phase Bugs

Draft phase refers to fresh smart contracts that are just developed and saying hello to the world. Bugs reported in the draft phase will be considered as development contributions. There will be no official bounty for the bugs reported in this phase, but there might be some rewards for those with extraordinary contributions.

As long as the bounty program is announced, the total token reward quota is capped at 6,000,000 HAKKA.
