Doug Colkitt

Doug Colkitt is an ex-high frequency trader, ex-MEV bot searcher, and founder of the decentralized exchange CrocSwap. In this episode, we talk about all three.  We begin with high frequency trading, where Doug walks us through the differences between maker and taker strategies, why queue position is so critical for makers, and why volatility is a high frequency trader’s best friend. We then discuss Ethereum-based MEV strategies.  Doug explains what MEV is, how the architecture of the Ethereum block chain allows it to exist, and a high level topology of the different types of MEV strategies that exist.  He also explains how the game theory behind MEV changed dramatically with the launch of Flashbots. Finally, we talk about his new decentralized exchange CrocSwap and its primary innovations, including dynamic fee levels, identification of toxic flow, and vaults that enable KYC. I hope you enjoy my conversation with Doug Colkitt.

The conversation covers market making, the mechanics of automated market makers, and risks involved in liquidity pools. Colkitt also discusses the importance of stable coins in DeFi and the integration of traditional financial assets on blockchain, envisioning a future where these technologies coexist harmoniously.

Eugene Chen, co-founder of Ellipsis Labs, and Doug Colkitt, co-founder of Crocodile Labs, discuss the evolving world of onchain trading and DEX designs, exploring factors like gas costs, latency, and modular "hooks". They debate the advantages of taking DEX components offchain and discuss the end game of DEX design.
