Biography

TLDR: I hack everything but enjoy Rust the most 🦀

I learned about Bitcoin in 2017, and the idea of decentralization and free money got me hooked instantly to the world of crypto. The DeFi summer of 2020 made me learn Solidity, explore various DeFi protocols, and become a web3 developer. Somehow, I found myself working on an ink! smart contract library (smart contracts for substrate's pallet-contracts) in late 2021. A new path appeared in 2023, however, and seemed very interesting to me - uncovering bugs in unfamiliar codebases while gobbling up more and more knowledge to protect web3. I also have a BSc in informatics.

🛠️ Previous work:

• Sol2Ink Solidity to ink! transpiler in Rust, based on Solang

fun fact, I used this on Uniswap V2 and compared to another AMM to identify this high severity issue in an audit competition

• OpenBrush ink! smart contract library
