Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. 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.
Critical smart contract vulnerabilities are capped at 10% of economic damage or maximum bounty, 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 15 000.
On the Vesting contract a critical or high bug has to affect vested funds.
All Medium, High and Critical Smart Contract bug reports require a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.
All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. All 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.
The following vulnerabilities are not eligible for a reward:
- All vulnerabilities found in Certik security review 1
- All vulnerabilities found in Certik security review 2
- All vulnerabilities found in Red4sec security review
Payouts are handled by the GhostMarket team directly and are denominated in USD. However, payouts are done in GM.

All smart contracts of GhostMarket can be found at https://github.com/OnBlockIO. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.
Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.
If an impact can be caused to any other asset managed by GhostMarket that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. This only applies to Critical and High impacts.
