Rewards by threat level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from the consequence of exploitation to privilege required to the likelihood of a successful exploit.
Smart Contracts and Blockchain
Critical — USD 50 000
High — USD 20 000
Medium — USD 3 000
Low — USD 1 000
All Low, Medium, High and Critical Smart Contract bug reports require a PoC and a suggestion for a fix to be eligible for a reward.
Issues that were already found here https://www.certik.com/projects/lossless are not eligible for a reward.
Payouts are handled by the Lossless team directly and are denominated in USD. However, payouts are done in USDC or USDT, with the choice of the ratio at the discretion of the team.
