Smart Contract & Blockchain Security Audits

SlowMist provides comprehensive white-box and gray-box security audits across the entire Web3 stack including smart contracts, exchanges, wallets, and blockchain infrastructure. The team has audited over 1,500 well-known smart contracts and discovered hundreds of high-risk and medium-risk vulnerabilities.

Smart Contract Audit Coverage

Professional security audits for smart contract source code across multiple blockchain platforms including Ethereum, EVM-compatible chains, EOS, Fabric, Solana, Klaytn, Aptos, Sui, Move-based blockchains, and other major networks. Audits cover Token Security and DeFi Security with extensive vulnerability detection including overflow audits, reentrancy attacks, race conditions, permission vulnerabilities, security design flaws, denial of service, gas optimization, design logic, flashloan attacks, replay attacks, and arithmetic accuracy deviations.

Platform-Specific Expertise

Solidity Audits: Comprehensive coverage for EVM-compatible contracts detecting 14+ vulnerability categories including overflow, race conditions, permission vulnerabilities, security design flaws, DoS, gas optimization, false top-up vulnerabilities, malicious event logs, replay attacks, uninitialized storage pointers, and arithmetic accuracy deviation.

Move Audits: Security assessments for Move-based blockchains (Aptos, Sui) covering overflow, replay attacks, flashloan attacks, race conditions, permission vulnerabilities, safety design, DoS, gas optimization, design logic, arithmetic accuracy, capability safe use, and resource security.

Solana Audits: Deep security analysis covering reentrancy, replay, reordering, DoS, race conditions, authority control, integer overflow/underflow, arithmetic accuracy, unsafe external calls, design logic, scoping/declarations, and forged account attacks.

EOS Audits: Full audit coverage including overflow, authority control, security design, DoS, performance optimization, design logic, false notice, counterfeit token, random number security, and rollback/replay attacks.

Exchange & Infrastructure Security Audits

Comprehensive gray-box security audits designed for cryptocurrency exchanges and blockchain infrastructure that go beyond traditional network attack and defense assessments. Audits evaluate exchange infrastructure including wallet integration, deposit/withdrawal mechanisms, trading engine security, API security, hot wallet management, cold storage solutions, user authentication systems, private key architecture security, and business logic security.

Wallet Security Assessments

Specialized security audits for all types of cryptocurrency wallets including hot wallets, cold wallets, hardware wallets, and mobile/web wallet applications. Assessments cover key generation and storage mechanisms, transaction signing processes, seed phrase management, backup and recovery procedures, multi-signature implementations, blockchain network integration, cryptographic implementation validation, secure enclave utilization, protection against malware and phishing, secure communication protocols, and proper implementation of BIP standards (BIP32, BIP39, BIP44).

Blockchain Protocol Security

Comprehensive security audits for blockchain infrastructure covering node configuration, node communication protocols, consensus algorithms, contract virtual machines, and other critical blockchain modules. Audits evaluate blockchain node implementations for configuration vulnerabilities, network communication security, consensus mechanism integrity, virtual machine execution safety, P2P networking security, block propagation mechanisms, state management, transaction pool security, and cryptographic primitive implementation.

Consortium Blockchain Solutions

Full-cycle security construction solutions for consortium (permissioned) blockchains designed to improve enterprise security and controllability. The comprehensive security framework addresses unique consortium blockchain challenges including permissioned access control, privacy requirements, regulatory compliance, and integration with existing enterprise systems. Coverage includes architecture design security, smart contract security, node security, network security, operational security, governance frameworks, security policies, monitoring systems, and incident response procedures.

Industry Recognition

SlowMist is the first Chinese company to enter the Etherscan smart contract security audit recommendation list. The audit report service has received the Best Security Audit Partner award from OKX.

Audit Process

Audits follow a structured workflow: Business Communication → Project Evaluation → Payment → Security Audit → Issue Report. Detailed audit reports document discovered vulnerabilities, risk assessments, and remediation recommendations prioritized by severity and impact. Audit reports are queryable through the SlowMist platform using token name, contract address, or audit number.
