Julien Niset - Argent and Account Abstraction

Devs Do Something

Today’s guest is Julien Niset, co-founder of Argent. Argent is a non custodial smart contract wallet that aims to improve UX across the entirety of web3. Julien has also become an expert & thought leader on account abstraction. In this episode, we deep dive account abstraction, how Argent works under the hood, and what app developers need to understand about all of this to build the next generation of web3 products.

Julien is also an ex-quantum physicist, so we got to ask him some fun cryptography questions as well (:

If you’re interested in improving UX for your users or just understanding the current state of account abstraction is at and what it’s all about, this episode is for you.
