Our security experts have discovered vulnerabilities in many important blockchain protocols, including Aptos, Sui,Stacks,  Ethereum, L2 protocol,etc., we have accumulated a lot of security technology. Whether it is L1 or L2 protocol, we can provide professional security services.

We offer comprehensive security audits for blockchain protocols. Our audits cover various aspects, including:

• Coding security: We analyze the codebase for vulnerabilities and weaknesses.
• Consensus protocol security: We assess the security of the mechanism used by the protocol to reach agreement on the state of the blockchain.
• Security risks across different layers: We identify and evaluate potential security risks at various levels, including consensus, RPC interaction, cryptography, smart contract virtual machine, data security, and economic model.

In addition to audits, we also provide the following security services:

• Technical guidance during the security development lifecycle: We can assist you in incorporating security best practices throughout the development process.
• Security consulting: We offer expert advice on securing your blockchain project.
• Security architecture design: We can help you design a secure architecture for your blockchain protocol.
