# Security Audits

> Audit status and security assessment recommendations for NullGraph protocol

# Security Audits

<Warning>
  **NullGraph has NOT undergone formal security audits.** This is a hackathon/demo project built for educational and demonstration purposes.
</Warning>

## Audit Status

### Current State

As of March 2026, NullGraph has:

* ❌ **No formal security audits** conducted
* ❌ **No third-party security review** performed
* ❌ **No penetration testing** completed
* ❌ **No economic security analysis** done
* ❌ **No formal verification** of smart contract logic
* ❌ **No bug bounty program** established

### Project Context

NullGraph was developed as a **hackathon submission** to demonstrate:

* Solana program development with Anchor framework
* SPL Token Interface integration for BIO token operations
* PDA-based account architecture
* Bounty marketplace mechanics for scientific data
* React frontend with Solana Wallet Adapter

The codebase prioritizes **functionality and demonstration** over production-grade security hardening.

<Info>
  This project is suitable for learning, experimentation, and proof-of-concept purposes. It is **not ready for production deployment** without significant additional security work.
</Info>

## Security Risks

### Critical Risks

Deploying unaudited smart contracts to mainnet exposes users to:

1. **Loss of funds** - Bugs in token transfer logic could lock or drain escrowed BIO tokens
2. **Unauthorized access** - Flaws in authorization checks could allow malicious actors to approve/close bounties
3. **Arithmetic vulnerabilities** - Despite checked arithmetic, edge cases may exist in fee calculations
4. **State corruption** - Race conditions or unexpected state transitions could brick accounts
5. **Economic attacks** - MEV, front-running, and other DeFi attack vectors not analyzed

### Known Limitations

See [Security Model - Known Limitations](/security/model#known-limitations) for detailed list of unimplemented security features.

## Pre-Production Checklist

<Warning>
  Complete ALL items before considering production deployment:
</Warning>

### 1. Code Audit

**Scope:** Full security review of `programs/nullgraph/src/lib.rs` (\~593 lines)

**Focus areas:**

* [ ] Authority validation in all instructions
* [ ] PDA seed derivation correctness
* [ ] Token transfer logic and vault authority
* [ ] Arithmetic overflow/underflow scenarios
* [ ] State machine transition validation
* [ ] Reentrancy protection
* [ ] Account validation completeness
* [ ] CPI security (SPL Token Interface calls)

**Recommended auditors:**

* [Zellic](https://www.zellic.io/) - Specializes in Solana/Anchor audits
* [Neodyme](https://neodyme.io/) - Solana-focused security firm
* [OtterSec](https://osec.io/) - Audits major Solana protocols
* [Trail of Bits](https://www.trailofbits.com/) - General smart contract auditing
* [Halborn](https://halborn.com/) - Blockchain security specialists

**Timeline:** 2-4 weeks for thorough review

**Budget:** $15,000-$50,000 depending on firm and scope

### 2. Testing & Coverage

**Requirements:**

* [ ] Unit tests for all instructions
* [ ] Integration tests covering full workflows
* [ ] Edge case tests (overflow, underflow, zero amounts)
* [ ] Negative tests (unauthorized access, invalid states)
* [ ] Fuzz testing with random inputs
* [ ] Code coverage >90%

**Current state:** Basic integration tests in `tests/nullgraph.ts` cover happy paths only.

### 3. Economic Security Analysis

**Research questions:**

* [ ] Can MEV bots front-run bounty submissions?
* [ ] Are there sandwich attack vectors in token transfers?
* [ ] What is the economic impact of protocol fee manipulation?
* [ ] Can malicious actors grief researchers or bounty creators?
* [ ] Are there sybil attack vectors in NKA submission?
* [ ] What is the optimal fee structure to prevent spam?

**Recommended partners:**

* Blockchain Capital research team
* Gauntlet (DeFi economic modeling)
* Chaos Labs (risk simulation)

### 4. Formal Verification

**Optional but recommended:**

* [ ] Formal specification of protocol invariants
* [ ] Model checking of state transitions
* [ ] Mathematical proof of core properties
* [ ] Symbolic execution of critical paths

**Tools:**

* [Certora Prover](https://www.certora.com/) - Formal verification platform
* [Solidity SMTChecker](https://docs.soliditylang.org/en/latest/smtchecker.html) - Static analysis (adapt for Rust)
* Academic partnerships for formal methods

### 5. Operational Security

**Infrastructure:**

* [ ] Deploy to mainnet with upgrade authority held by multisig
* [ ] Implement timelock for protocol parameter changes
* [ ] Set up monitoring and alerting for suspicious activity
* [ ] Establish incident response procedures
* [ ] Create security disclosure policy
* [ ] Set up bug bounty program

**Key management:**

* [ ] Protocol authority in cold storage or multisig
* [ ] Treasury wallet in hardware wallet or multisig
* [ ] No single point of failure in key custody

### 6. Bug Bounty Program

**Structure:**

* Critical vulnerabilities: \$50,000+
* High severity: $10,000-$50,000
* Medium severity: $2,000-$10,000
* Low severity: $500-$2,000

**Platforms:**

* [Immunefi](https://immunefi.com/) - Largest web3 bug bounty platform
* [HackerOne](https://www.hackerone.com/) - General bug bounty
* [Code4rena](https://code4rena.com/) - Competitive audits

### 7. Testnet Deployment

**Timeline:** Minimum 3-6 months on devnet/testnet before mainnet

**Objectives:**

* [ ] Stress test with high transaction volume
* [ ] Public testnet with real users (fake tokens)
* [ ] Monitor for unexpected behavior or edge cases
* [ ] Iterate on fixes without mainnet risk

### 8. Documentation & Transparency

**Required materials:**

* [ ] Comprehensive security documentation (in progress)
* [ ] Architecture diagrams
* [ ] Threat model documentation

## Responsible Disclosure

### Reporting Vulnerabilities

If you discover a security vulnerability in NullGraph:

1. **Do NOT disclose publicly** until patched
2. Contact the development team through secure channels
3. Provide detailed reproduction steps
4. Allow reasonable time for remediation (90 days standard)

### Disclosure Timeline

**Standard process:**

* Day 0: Vulnerability reported to team
* Day 1-7: Team confirms and assesses severity
* Day 7-30: Fix developed and tested
* Day 30-60: Fix deployed to production
* Day 60-90: Public disclosure with credit to researcher

<Note>
  Critical vulnerabilities affecting funds may require expedited disclosure and emergency patches.
</Note>

## Security Best Practices for Users

### For Researchers

* ✅ Only connect trusted wallets (Phantom, Solflare)
* ✅ Verify transaction details before signing
* ✅ Keep seed phrases secure and offline
* ✅ Use hardware wallets for high-value accounts
* ❌ Never share private keys or seed phrases
* ❌ Don't approve suspicious transactions

### For BioDAOs and Bounty Creators

* ✅ Start with small bounty amounts to test
* ✅ Verify researcher credentials before approval
* ✅ Monitor vault balances regularly
* ✅ Use multisig wallets for treasury operations
* ❌ Don't create bounties with entire treasury balance
* ❌ Don't approve submissions without thorough review

### For Protocol Integrators

<Warning>
  **Do NOT integrate NullGraph into production applications** until formal security audits are completed and all pre-production checklist items are addressed.
</Warning>

If building on NullGraph for hackathons or demos:

* Use devnet/testnet only
* Clearly label as "experimental"
* Include security disclaimers
* Never handle real user funds
* Keep dependencies updated

## Conclusion

NullGraph demonstrates innovative mechanics for tokenizing scientific null results, but **requires significant security investment** before production deployment.

<Info>
  This documentation is intentionally transparent about security limitations. Honesty about audit status and risks is critical for user safety and project credibility.
</Info>

**Current recommendation:** Use for learning, demos, and hackathons on devnet/testnet only. Do not deploy to mainnet or handle real funds without completing the pre-production checklist.
