In the rapidly evolving world of Web3, security remains a paramount concern for users engaging in cryptocurrency transactions. KEKKAI, a Japanese Web3 security startup, has recently completed a Pre-Seed funding round to advance its mission of making digital asset interactions safer and more transparent.
Understanding the Need for Advanced Web3 Security
As cryptocurrency adoption grows, so do the sophistication and frequency of security threats. Many users rely on digital wallets for transactions, yet these interfaces often present "unreadable" signature requests that obscure potential risks. This lack of clarity can lead to unintended asset loss or exposure to fraudulent schemes.
KEKKAI addresses this critical gap by providing real-time risk assessment during transactions. By analyzing and simulating transaction data, the platform offers users clear, actionable insights into potential threats before they finalize any operation.
How KEKKAI's Security Solution Works
KEKKAI’s approach centers on a two-step process: transaction data analysis combined with simulation, followed by comprehensive risk evaluation.
Step 1: Transaction Data Analysis and Simulation
When a transaction is initiated, KEKKAI interacts with Ethereum Virtual Machine (EVM) nodes to execute and analyze transaction data. The system interprets smart contract-related opcodes to predict the transaction’s outcome. This allows users to preview potential results—such as losing a specific amount of Ethereum, purchasing an NFT, or transferring assets—before committing.
Step 2: Risk Assessment and Alerting
Based on the simulation, KEKKAI evaluates multiple security parameters. For example, when assessing NFT transactions, it verifies whether the NFT has OpenSea’s blue checkmark authentication, checks the legitimacy of the contract, and monitors price fluctuations. If anomalies or known fraud patterns are detected, KEKKAI immediately displays a warning, such as "Warning," to alert the user.
Combating Common Web3 Fraud Types
KEKKAI has identified and built protections against several prevalent cryptocurrency fraud schemes, including:
- eth_sign (Blind Signing): Prevents unauthorized or unclear signature requests.
- Gasless Transaction (Zero-Cost Scams): Flags transactions that may exploit gas-free mechanisms maliciously.
- Set Approval for All: Alerts users to token authorization risks.
- Fake NFT and Token Fraud: Detects counterfeit assets and unverified contracts.
- Rug Pulls and Honeypots: Identifies liquidity scams and fake investment traps.
The team continuously updates its database with new threat patterns to stay ahead of emerging risks.
Current Product Offerings and Future Roadmap
KEKKAI is currently available as a browser extension, ensuring seamless integration with major Web3 platforms and wallets. The company is also developing PC and mobile applications to expand accessibility. With support for approximately 70 EVM-compatible chains, KEKKAI offers broad coverage across the decentralized ecosystem.
Looking ahead, KEKKAI aims to partner with wallet providers and other Web3 service operators, positioning itself as a B2B security solutions provider in addition to serving end-users.
