Comprehensive Blockchain Security Coverage
From cryptographic primitives to DeFi protocols – we assist with every layer of blockchain security.
📜 Smart Contract Vulnerability Analysis
- Reentrancy Attacks – The DAO hack (2016), patterns for safe external calls (checks‑effects‑interactions).
- Integer Over/Underflow – SafeMath libraries, Solidity 0.8+ built‑in checks.
- Access Control Vulnerabilities – Missing `onlyOwner`, public initialization functions.
- Front‑running / Transaction Ordering Dependence – Commit‑reveal schemes, private mempool.
- Denial of Service (DoS) – Unbounded loops, assert failures.
- Audit Tools – Slither, Mythril, Echidna, Manticore; how to run and interpret output.
⛓ Consensus Mechanism Security
- Proof of Work (PoW) – 51% attack, selfish mining, block reorganisations.
- Proof of Stake (PoS) – Nothing‑at‑stake, long‑range attacks, slashing, validator collusion.
- Delegated PoS (DPoS) – Centralisation risks, vote buying.
- Practical Byzantine Fault Tolerance (PBFT) – 1/3 malicious nodes threshold, attack scenarios.
- Comparison Matrix – Throughput, finality time, energy consumption, security assumptions.
🔑 Wallet & Key Management Security
- Hot vs. Cold Wallets – Tradeoffs, air‑gapped signers, hardware wallets (Ledger, Trezor).
- HD Wallets (BIP32, BIP39, BIP44) – Mnemonic phrases, derivation paths, child key generation.
- Multi‑signature (Multi‑sig) – M‑of‑N, smart contract multi‑sig vs. native (BTC).
- Social Recovery Mechanisms – Shamir’s secret sharing, guardian wallets.
- Common Pitfalls – Seed phrase exposure, phishing, clipboard malware.
💰 DeFi & DApp Security
- Flash Loan Attacks – Uncollateralised borrowing, price manipulation (e.g., bZx, PancakeBunny).
- Oracle Manipulation – Using few or centralised price feeds, TWAP vs. spot price.
- Governance Attacks – Proposal flooding, token lending to pass votes.
- Yield Farming Risks – Impermanent loss, risky strategies, protocol composability.
- Risk Modelling – Value at Risk (VaR) for DeFi, risk rating frameworks.
🔗 Layer 1 & Layer 2 Security
- Ethereum – Client diversity, slashing, gas limit attacks.
- Bitcoin – UTXO model, fee replacement (RBF), dust attacks.
- Solana / Sui / Aptos – Parallel execution risks, validator requirements.
- Rollups (ZK & Optimistic) – Fraud proofs, validity proofs, bridge security, escape hatches.
- Sidechains & Bridges – Cross‑chain vulnerabilities (Ronin, Wormhole).
🧾 Regulatory & Privacy
- Privacy Coins – Monero (RingCT, stealth addresses), Zcash (zk‑SNARKs).
- Travel Rule & AML – FATF recommendations, tracking tools (Chainalysis).
- Self‑sovereign identity (SSI) – DIDs, verifiable credentials.
