Learn how we work from first principles to viable products.
LLMs are wonderful at predicting the next character in a text. But they can also predict the next trace opcode of a blockchain transaction! Hence they can detect which next opcode is rather unlikely --- we use this insight to create an abnormality detection system.

Instead of joining the monkey game of find profitable opportunities, why not simply copy them? We investigate an advanced method to imitate blockchain transactions in real-time, allowing to generate hundreds of millions of USD. This work was published in Usenix Security.

Traders extract monetary value from the mesh of decentralized finance (DeFi) smart contracts through so-called blockchain/miner/maximal extractable value (BEV/MEV). We shed light into this dark forest with an IEEE Security & Privacy Paper.
