Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.1. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
All Medium, High and Critical Smart Contract bug reports require a PoC to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.
Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 20 000.
All vulnerabilities marked in the Quantstamp security review are not eligible for a reward.
Payouts are handled by the Gelt team directly and are denominated in USD. However, payouts are done in USDC and DAI, with the choice of the ratio at the discretion of the team.
- Up to USD $100,000
- USD $10,000
- USD $1,000
