Hello! I’m 0xkato — a security engineer deeply embedded in the web3 space.

Since late 2022, I’ve worked closely with protocols across the stack, offering both internal and external security support. I focus on consensus protocols, node implementations, execution clients, and smart contracts — helping teams harden their systems before going to mainnet.

If you're working on something and want a second set of eyes — or just want to chat security — feel free to reach out.
