The following is the public profile of my career as a blockchain Security Researcher and Smart Contract Auditor.
I'm Alin Mihai Barbatei, also know as ABA. I'm an independent security researcher with a strong focus on blockchain security. My career started in traditional software security, which has given me a solid foundation for uncovering complex vulnerabilities. Over the years, I've gained significant experience securing both EVM (Ethereum Virtual Machine) compatible blockchain projects and Bitcoin L2, particularly Stacks, projects.
I've conducted a number of solo and collaborative smart contract security reviews. I take pride in delivering thorough and comprehensive smart contract audits that stand out for their quality.
If you’re interested in learning more about what I do, you can check out my blog at abarbatei.xyz. You can also take a look at my audit portfolio there. For audit bookings or if you have any security review inquiries, feel free to reach out to me on Telegram, Twitter (X), or WarpCast:
