Arunabha Dhal

Blockchain Developer & Junior Security Researcher

About Me

I'm a final year undergraduate student at IIT Indore, specializing in blockchain development, smart contract security, DevOps, and backend engineering. I'm an aspiring security researcher focused on EVM chains and the Bitcoin network.

Currently, I'm diving deep into DeFi mechanics, low-level Solidity, and formal verification to enhance my expertise in blockchain security and development.
