| Reentrancy Attack | Malicious contract recursively calls withdrawal function, draining funds | Check-effects-interaction pattern, reentrancy locks |
| Integer Overflow/Underflow | Arithmetic operations exceed range, causing abnormal balances | SafeMath library, Solidity 0.8+ built-in checks |
| Permission Vulnerability | Unauthorized users execute admin operations | Fine-grained permission control, multi-signature mechanism |
| Flash Loan Attack | Use flash loans to manipulate price oracles | Time-weighted average price, multi-source oracles |
| Logic Errors | Business logic design flaws | Formal verification, multi-round business logic audit |
2. On-Chain Risk Control System Solutions
On-chain transactions have anonymous, fast, and irreversible characteristics; once malicious behavior occurs, it is often difficult to recover. Our on-chain risk control system provides real-time monitoring and automatic intervention capabilities, helping projects block risks before or early in their occurrence.
Product Capabilities:
- Abnormal transaction identification: Real-time analysis of transaction amounts, frequencies, and path patterns; flag behaviors such as large transfers, high-frequency interactions, abnormal recursive calls
- Address risk scoring: Integrate blacklist libraries from multiple security vendors; risk-rate accounts interacting with mixers, attack contracts, and money laundering addresses
- Real-time risk warning system: When high-risk transactions are detected, system automatically alerts administrators, with configurable automatic interception strategies
- Policy customization: Projects can flexibly configure risk control rules based on their business characteristics
Core Value Proposition: Real-time monitoring of on-chain behavior, automatic identification of potential attacks and abnormal fund flows, support policy customization, achieve "pre-warning, mid-interception"
Business Value: Early detection and prevention of attack behaviors, avoid systemic losses, protect platform user asset security
| Risk Scenario | Detection Method | Automatic Response Measures |
|---|---|---|
| An address interacts with known attack contract | Address blacklist matching | Real-time alert + automatic freeze of that address's transactions |
| Large amount of tokens transferred out in short time | High-frequency transaction detection | Trigger delayed withdrawal review (e.g., 24 hours) |
| Price oracle manipulation | Price deviation from multi-source data threshold | Pause related lending or trading pairs |
| A contract immediately transfers large amount after deployment | New contract behavior analysis | Temporarily restrict that contract's calls to core functions |
3. Wallet and Private Key Security Solutions
Wallets are the final storage location for user assets; private key leakage means complete loss of asset control. We provide multi-layered, multi-mode wallet security solutions balancing security and usability.
Product Capabilities:
- Private key encryption and sharding: Using Multi-Party Computation (MPC) technology to split private keys into multiple fragments stored in different locations; no single fragment can reconstruct the complete private key

III. Core Capabilities: Building "Active Defense + Real-Time Monitoring + Automatic Response" Security System
1. Full Lifecycle Security Management
Traditional security often ends with a single audit before launch, but blockchain projects are continuously evolving; new features and contracts are constantly deployed, and risks change accordingly. Our security solutions cover the complete lifecycle of three stages: pre-development, during development, and post-launch.
| Stage | Content |
|---|---|
| Pre-development (Security Design) | Introduce threat modeling at project architecture design stage, identify potential attack surfaces, establish secure coding standards |
| During Development (Code Audit) | Conduct incremental audits for each completed module to avoid issues accumulating until pre-launch |
| Post-launch (Continuous Monitoring) | Through on-chain monitoring, bug bounty programs, regular penetration testing, ensure continuous security |
Business Value: Security runs through the entire project lifecycle, not just a one-time check before launch; truly achieve "security shift left"
2. Multi-Layer Defense System (Defense-in-Depth)
Any single protection measure may be bypassed, so we have built multi-layered superimposed protection mechanisms from the underlying layer to the application layer.
| Layer | Protection Measures |
|---|---|
| Contract Layer | Security audit, formal verification, bug bounty |
| Application Layer | Account risk control, transaction monitoring, API security |
| Network Layer | DDoS protection, node isolation, encrypted communication |
| Data Layer | Encrypted storage, access control, backup and recovery |
Business Value: Even if one layer of protection fails, other layers can still function; the overall system remains secure
3. Automated Security Capabilities
Manual response speed is limited; automated capabilities can complete risk identification and handling at millisecond levels.
- Automatic vulnerability scanning (CI/CD pipeline integration)
- Automatic risk behavior identification (on-chain rules engine)
- Automatic defense triggering (such as freezing addresses, pausing transactions)
Business Value: Reduce manual operation costs, improve security response speed, reduce vulnerabilities caused by human negligence
4. Security Policy Configurability
Different projects have different security requirements at different development stages. Our solutions support flexible configuration to avoid one-size-fits-all approaches.
| Configuration Item | Description |
|---|---|
| Custom risk control rules | e.g., "Single address withdrawing more than 10 ETH within 24 hours requires secondary review" |
| Flexible security level adjustment | Testnet can reduce verification intensity, mainnet enables highest level |
| Support different business scenarios | DeFi, NFT, GameFi each have different focuses |
Business Value: Security and business flexibly matched; both ensure security and not compromise user experience
| Business Scenario | Recommended Security Level | Key Configuration Items |
|---|---|---|
| DeFi lending protocol | Extremely high | Contract multi-signature management, price oracle protection, emergency pause switch |
| NFT trading market | High | Anti-money laundering detection, abnormal bidding monitoring, copyright verification |
| GameFi games | Medium | Anti-script automation, item trading limits, anti-cheat mechanisms |
| Internal consortium chain | Medium-high | Node access control, data isolation, audit logs |
IV. Core Value Propositions: From "Security Protection" to "Trust Asset"
1. Security is Trust
In the Web3 world, security capability directly determines whether users dare to store assets on your platform. A single security incident may cause permanent user loss.
Result: Improved user retention rates, institutional capital more willing to enter
2. Security is Growth
Security is not a cost center but a growth engine. A proven secure platform more easily attracts capital accumulation, and users are more willing to make large transactions.
Result: Security becomes the fundamental condition for user growth, forming a positive cycle of "more secure → more users → more capital"
3. Security is Compliance
Global regulators have increasingly strict compliance requirements for Web3 platforms; KYC, AML, and data privacy protection have become basic thresholds.
Result: Support long-term legal project operation, avoid regulatory fines or shutdown risks
4. Security is Barrier
Building a high-level security system requires deep technical accumulation and continuous investment, which itself is a difficult-to-surpass competitive barrier.
Result: Build long-term competitive advantage, become industry security benchmark
5. Security is Cost Control
A severe hacker attack may cause losses of millions or even hundreds of millions of dollars, far exceeding security investments.
Result: Reduce uncontrollable losses, improve project profitability stability
| Project Scale | Annual Security Investment Estimate | Typical Attack Potential Loss | Security ROI |
|---|---|---|---|
| Small DeFi (TVL $1M) | $5,000 - $20,000 | $50,000 - $500,000 | 250% - 10000% |
| Medium exchange (daily trading volume $10M) | $50,000 - $200,000 | $500,000 - $5,000,000 | 150% - 10000% |
| Large public chain ecosystem | $200,000+ | $10,000,000+ | Far exceeds 5000% |
