Solidly Bug Bounty on Immunefi

Smart contract fails to deliver promised returns, but doesn’t lose value.

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 consequence of exploitation to privilege required to likelihood of a successful exploit.

All Critical/High smart contract bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. All Critical/High smart contract bug reports must also come with a suggestion for a fix in order to be considered for a reward.

Rewards for critical smart contract vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum reward of $50 000 for Critical bug reports.

The following known issues are considered to be out-of-scope of this bug bounty program:
