安全评审与修复评估
用我们的自研工具（必要时可定制）完成一次完整的安全评估。发现会同步给客户，随后就修复方案展开讨论。规模更大或更复杂的项目可能需要多轮评审，以确保所有问题都被修掉。
最终报告与可落地的建议
交付一份签署的报告，包含全部发现、风险评估与详细的修复建议，并为每个漏洞给出清晰的处置步骤。
我们把自研测试框架与对架构的深入理解结合起来，帮助强化你区块链生态的稳定性与安全性。
“We had a great experience working with BlockSec on the security testing of Mega-EVM, our stateless validator, and the SALT data structure. They're responsive, diligent, and easy to collaborate with, with a fast feedback loop throughout the audit. Their deep expertise across both smart contracts and node-level systems made them a strong partner for complex infrastructure work.”
“On the audit side, the BlockSec team has left a very positive impression on us. Their audits are never a mere formality; instead, they dive deep into contract implementation details and specific business logic, covering edge cases and extreme scenarios that are often overlooked. The entire process was smooth and highly efficient. Their bug localization and remediation advice were clear and actionable, helping us significantly reduce potential security risks before product launch.”
“BlockSec has built a strong reputation for conducting highly technical audits for blockchains and smart contracts. Supporting Solidity (EVM-compatible ecosystems), Rust (NEAR & Solana), and Go (Cosmos), the company primarily relies on thorough manual reviews, enhanced by automated differential fuzzing tools and static analyzers. This approach allows BlockSec to identify deep logic flaws in code and provide actionable recommendations to ensure project security before launch.”
“BlockSec's deep expertise in smart contract security has been invaluable to exSat. Their rigorous audits consistently uncover subtle yet critical vulnerabilities, delivering clear, practical remediations. With their meticulous, code-level scrutiny, we gain unparalleled confidence in our protocol's integrity—making BlockSec our trusted partner for secure, resilient smart contracts.”
