Today’s guest is Richard Meissner, co founder & CTO at Safe. Richard is an expert on all things smart contract wallets, and we used this episode to go deep into account abstraction. In particular, we discussed the Safe contract architecture and how things like Safe modules & smart contract wallets work under the hood. The Safe team has rolled out a ton of new libraries & tech that make supporting smart contract wallets and AA a breeze, and we discussed them as well. 00:00 Intro 3:55 How Richard got into the industry 8:31 The Safe contract architecture 14:13 Safe modules 17:11 Misconceptions and account abstraction 20:45 ERC 4337 Infrastructure  23:11 How app developers can make proper use of smart contract wallets 25:45 What does the ecosystem need to do to enable better UX? 29:50 Solving the YOLO signing problem 36:37 The Safe Core Suite 42:30 Frictionless onboarding  50:08 How Richard & the Safe team approach smart contract security 56:00 Advice for early career devs 59:45 What does Richard hope our industry looks like in 10 years?
