Smart Contract Audits
Smart Contract Audits
Security in Detask is not an afterthought—it’s a foundational design principle. The smart contracts that govern Detask’s workflow, from task creation to payout, are subjected to rigorous audit processes and formal verification to ensure resilience against exploits, vulnerabilities, and failures.
🔐 Why Auditing is Essential
Smart contracts are immutable once deployed, meaning any vulnerability can lead to irrecoverable loss of funds or reputational damage. In Detask:
Funds are locked in PDAs, representing high-value escrow pools.
Deliverables are validated via cryptographic proofs, which must be securely enforced on-chain.
On-chain reputation mechanisms depend on data integrity and constraint validation.
Thus, ensuring code correctness is vital.
🏗️ Audit Process Workflow
1️⃣ Internal Code Review
The Detask development team conducts multiple rounds of peer review on the Anchor-based smart contracts.
Focus areas include:
Correct serialization/deserialization of task metadata.
Access control enforcement via Anchor’s constraints.
Integrity of proof submission linkage and payout logic.
Prevention of common vulnerabilities (e.g., reentrancy, integer overflows).
2️⃣ Static Analysis Tools
Tools like Solana Auditor, Soteria, and Anchor Linter are used to detect:
Unsafe deserialization patterns.
Constraint bypasses or permission leaks.
Gas consumption spikes that could block execution.
3️⃣ Formal Verification (Future Integration)
Formal methods (e.g., Coq, Move Prover) will mathematically model Detask’s critical smart contract properties:
Escrow funds are only released when proofs meet preconditions.
Funds cannot be transferred to unauthorized addresses.
Task states transition atomically without race conditions.
Model-checking ensures contracts behave as intended under all valid inputs.
4️⃣ Third-Party Audits
Independent auditors (e.g., Halborn, CertiK, Neodyme) will review the smart contracts, focusing on:
Vulnerability discovery and remediation recommendations.
Gas optimization for scalability.
Documentation and test coverage validation.
Simulation of complex attack vectors (e.g., Sybil attacks on reputation systems, proof forgery).
⚙️ Key Audit Focus Areas
🧩 1. Task Creation and Escrow Logic
Validation of task metadata (description, budget, deadlines).
Secure fund locking in PDAs without external interference.
Prevention of duplicate task records or unauthorized overwrites.
🧩 2. Proof Submission Verification
Integrity checks on cryptographic hashes and off-chain URIs.
Ensuring that only authorized freelancers can submit proof for a task.
Mitigating risks of duplicate submissions or front-running attacks.
🧩 3. Payout Execution
Atomic release of funds upon valid proof approval.
Rejection of payouts to wallets not matching task records.
Event emission for off-chain monitoring and auditability.
🧩 4. Access Control and State Transitions
Enforcing state constraints (e.g., task must be “open” for proof submission).
Preventing unauthorized state changes or cancellations.
Secure role assignments (task creator vs. freelancer vs. validators).
🔍 Continuous Monitoring & Upgrades
Event Logs: All critical contract interactions (task creation, submission, approval, payout) generate logs for off-chain analysis.
Upgradable Architecture: Future iterations may use Solana’s program upgrade authority for critical patches, gated by multi-signature governance.
Bug Bounty Programs: Planned incentive schemes to reward white-hat researchers for discovering vulnerabilities preemptively.
🌐 Security Beyond Code
Key Management: Emphasizing the use of hardware wallets or multi-sig setups for high-value task creation.
User Education: Providing clear guidelines for secure wallet usage and signature verification.
Rate Limiting & Anti-Spam: Preventing DoS attacks by implementing task creation rate limits and submission quotas.
💡 Summary
Smart contract audits are essential to ensuring Detask’s credibility and resilience. By combining internal reviews, static analysis, formal verification, and independent audits, Detask establishes a robust security posture that protects funds, data, and reputation.
This is the first line of defense for a decentralized work protocol that aims to operate trustlessly at scale.
