6.6. 5% Bug Bounty (Immunefi)

The 5% Bug Bounty allocation formalizes the protocol’s commitment to proactive, community-driven security. Receiving 5% of the net fee distribution (equivalent to 0.015% of the winning bid), this fund is exclusively dedicated to rewarding ethical hackers and security researchers who responsibly disclose critical, high, or medium-severity vulnerabilities before they can be exploited maliciously.

Hosted on the Immunefi platform, the program operates as a continuous vulnerability disclosure program (VDP) that complements external audits, automated monitoring, and the Insurance Fund. By aligning financial incentives with proactive threat discovery, the protocol ensures that its cryptographic, economic, and infrastructure layers remain hardened against emerging attack vectors.

Core Allocation Mechanics

Economic Flow Example

For an auction with a winning bid of 100 ETH:

1. Success Fee (0.5%): 0.5 ETH collected.
2. Keeper Bounty (0.2%): 0.2 ETH paid to the executor.
3. Net Fee: 0.3 ETH remains for distribution.
4. Bug Bounty (5% of Net): Receives 0.015 ETH. (The remaining 0.285 ETH is split among Treasury, Insurance, and Developer Grants).

️ Technical Implementation & Payout Workflow

1. Deterministic Routing (BugBountyVault.sol)

The allocation is mathematically enforced at the contract level, ensuring continuous vault accumulation without discretionary overrides.

// Conceptual Bug Bounty Routing Logic
function _allocateNetFees(uint256 netFeeAmount) internal {
 require(netFeeAmount > 0, "No fees to allocate");
 
 // Bug Bounty receives 5%
 // Calculation: (netFee * 5) / 100
 uint256 bountyShare = (netFeeAmount * 5) / 100;
 
 // Route to dedicated Bug Bounty Vault (Multisig/Immunefi Controlled)
 bugBountyVault.deposit(bountyShare);
 
 emit BugBountyAllocation(bountyShare, block.timestamp);
}

2. Immunefi VDP Integration

Payout execution follows a secure, multi-step verification process managed through Immunefi’s infrastructure:

1. Discovery & Submission: Researcher submits report via Immunefi platform with reproducible Proof-of-Concept (PoC).
2. Triage & Validation: Immunefi security engineers verify impact, scope, and reproducibility.
3. Severity Assessment: Classified as Critical, High, or Medium per CVSS/Immunefi Impact Matrix.
4. Payout Execution: Approved amount is disbursed from the BugBountyVault via governance multisig or Immunefi’s treasury bridge to the researcher’s verified wallet.
5. Post-Resolution: Vulnerability is patched, audit matrix is updated, and optional responsible disclosure is published.

Severity Tiers & Scope Alignment

Security Note: The Bug Bounty program explicitly excludes “Funds Over Privacy” emergency triggers from bounty eligibility, as EmergencyHalt is a designed safety mechanism, not a vulnerability.

️ Security & Economic Guarantees

1. Pre-Exploit Incentivization: By offering competitive payouts, the protocol ensures that white-hat researchers report vulnerabilities before malicious actors can discover and exploit them, reducing systemic risk.
2. Scope-Driven Validation: Only in-scope, reproducible vulnerabilities are eligible. Theoretical, non-actionable, or out-of-scope findings are explicitly excluded to prevent bounty farming.
3. Governance-Gated Disbursement: All payouts require verification by Immunefi triage + protocol multisig approval, preventing fraudulent claims or automated vault drainage.
4. Continuous Hardening Loop: Every validated bug triggers an update to the Audit Readiness Matrix, Slither/Mythril rules, and CI/CD linters, ensuring the same vulnerability class cannot be repeated.
5. Transparency & Trust: While researcher identities may remain pseudonymous, Immunefi’s public leaderboard and payout history provide verifiable proof of the protocol’s commitment to security accountability.

Audit Gate Compliance (P1 - Pre-Mainnet)

Progression to Mainnet deployment requires the Bug Bounty module to pass the following verification gates:

• [] Deterministic Math Verification: Unit tests confirm (netFee * 5) / 100 is precise and handles dust correctly.
• [] Vault Ownership & Access: owner() of the Bug Bounty Vault points to the Governance/Multisig address, not an EOA.
• [] Immunefi Program Live: Official program page published with clear scope, severity tiers, and payout ranges.
• [] Event Transparency: BugBountyAllocation event is emitted and indexed for every settlement.
• [] Responsible Disclosure Policy: Published SECURITY.md and Immunefi VDP guidelines explicitly outline submission, triage, and patch timelines.
• [] Zero Discretionary Overrides: No single address can sweep the Bug Bounty vault without multisig approval + timelock.

Unresolved Points & Explicit Gaps

Fact vs. Analysis Distinction: The 5% allocation rate, Immunefi platform integration, severity-driven payout structure, and governance-gated disbursement are verified facts from the official Whitepaper and Technical Specification. The exact payout caps, automation architecture, and infrastructure scope extensions are unresolved operational gaps requiring explicit definition before Mainnet launch.
