Security practices, audit reports, and vulnerability disclosure for DeLong Protocol.

Audit Status

Status: Pending

Planned Auditors: TBD

Audit Scope:

• Factory.sol
• IDO.sol
• DatasetToken.sol
• Governance.sol
• RentalPool.sol
• VirtualAMM.sol (library)

Audit Reports: Available after completion

Security Features

No Admin Keys

Zero privileged roles or admin functions across all contracts. No emergency withdrawals, no pause mechanisms, no upgrade paths after initialization.

Immutable Deployment

EIP-1167 minimal proxies with one-time initialization. No upgradeable proxy patterns or delegatecall vulnerabilities.

Snapshot Voting

ERC20Votes checkpoints prevent flash loan attacks and double voting via historical balance queries at block.number - 1.

Reentrancy Protection

ReentrancyGuard applied to all state-changing functions in IDO, Governance, and RentalPool contracts.

Slippage Protection

User-specified limits on all swap functions:

• maxUSDCIn / minTokensOut for buying
• maxTokensIn / minUSDCOut for selling

Decimal Safety

Explicit decimal handling with comments throughout codebase:

• USDC: 6 decimals
• Dataset tokens: 18 decimals
• Dividend precision: 1e18 scaling

Initialization Guards

_initialized flags prevent re-initialization attacks on cloned minimal proxies.

Known Limitations

No Governance Upgrades Post-Launch

Governance strategy can only be changed via GovernanceUpgrade proposals (requires 50% quorum). Initial strategy is immutable simple majority.

No Emergency LP Unlock

LP tokens locked permanently except via democratic delisting. No circuit breakers or emergency unlocks exist.

Rounding Dust

Small rounding errors possible in dividend distribution due to fixed-point arithmetic. Dust amounts (<0.000001 USDC) may accumulate in RentalPool.

Bug Bounty

Status: TBD

Scope: All core protocol contracts

Rewards: TBD

Exclusions:

• Frontend/UI bugs
• Gas optimizations
• Known limitations listed above

Disclosure: security@delong.xyz (email TBD)

Responsible Disclosure

If you discover a security vulnerability:

1. Do not publicly disclose the issue
2. Email details to security@delong.xyz
3. Include steps to reproduce, impact assessment, and suggested fix
4. Allow 90 days for patch development and deployment
5. Coordinated disclosure after fix deployment

Security Best Practices

For Users

Verify Contracts - Always check contract addresses on deployed-contracts.md before interacting.

Approve Carefully - Only approve exact amounts needed for transactions, not unlimited approvals.

Check Slippage - Use appropriate slippage limits during volatile market conditions.

Verify Proposals - Review proposal details and discussion before voting, especially for large treasury withdrawals.

For Developers

No Private Keys in Code - Never commit private keys, mnemonics, or API keys.

Test Thoroughly - Run full test suite before deploying integrations.

Monitor Events - Listen to contract events for unexpected state changes.

Handle Reverts - Implement proper error handling for all contract calls.
