This is a public profile of my adventure as an independent blockchain and smart contract security researcher.
Currently, I'm a lead security auditor at Oak Security (and Solidified), senior auditor at trust-security.xyz, security researcher at Spearbit, top warden & judge at Code4rena, and a (prev. senior) watson at Sherlock.

I'm available for web3 security consulting and private security reviews. Please reach out to me on Twitter (@berndartmueller) or Telegram (bernd_42) if you're interested.
