The section on regulatory challenges was eye-opening.

Which part in the architecture supports multisig wallets and private key replacements?

What if the chain that we have is an L1-EVM, but is gasless already? Would our wallet still work?

I understand nothing, i speak French...small English, it's possible, but technically 🤷... but i follow you 👍practice makes perfect 🥰

Nice explanation, finally AA is fitting in my brain. I was looking to implement a spend limiter using ERC 4337 on any EVM chain (Polygon for example). Could you point me to wards any resources which I should refer to, or in general help out in what needs to be done to implement a feature like that?.

Thank You

Do stackup use Layer 2 chains ??? like zk synk or rollups? Because using ethereum L1 chain may increase the gas fee, if opted for L2 we may avoid useroperation mempool, Bundler, Handleops

Can you explain how private keys tie into 4337 wallets? Is the idea that someone / some company has private keys and these alone are used to create the smart contract wallets for all users?

Curious about Account Abstraction? Portkey's AA wallet simplifies your Web3 journey. It allows you to sign up with your Web2 details, granting access to decentralized identities and assets. It's all about making Web3 more accessible and user-friendly.
