Critical Reward Calculation

Mainnet assets:

Reward amount is 10% of the funds directly affected up to a maximum of:

$100,000

Minimum reward to discourage security researchers from withholding a bug report:

$20,000

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.

Audit Discoveries and Known Issues

Bug reports covering previously-discovered bugs are not eligible for any reward through the bug bounty program. If a bug report covers a known issue (e.g., the use of deprecated Chainlink API was reported in EXA-36), it may be rejected together with proof of the issue being known before escalation of the bug report via Immunefi.

Previous audits and known issues can be found at: https://docs.exact.ly/security/audits.

All 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.

KYC is required for this bug bounty program. Government identification, legal name, and country of residence will need to be supplied.

Payouts are handled by the Exactly team directly and are denominated in USD. However, payouts are done in USDC and DAI, with the choice of the ratio at the team's discretion.

KYC required

The submission of KYC information is a requirement for payout processing.

Proof of Concept

Proof of concept is always required for all severities.

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • Any testing with pricing oracles or third-party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
