open browser wallet update: import existing smart wallets!

this means you can use your coinbase smart wallet with a passkey on another domain (and via walletconnect!)

in this demo i walk through the entire process
- creating a new smart wallet account
- adding a recovery owner
- importing it into open browser wallet
- executing a swap on uniswap using walletconnect

this is still WIP, and currently only works on base. working on replaying add owner transactions on other chains (there's $0.01 for someone if they steal this demo seed phrase :p)

base-builds

this weekend i participated in the based africa hackathon and built a stablecoin wallet with a built-in store for purchasing goods where the orders are fulfilled offchain

this was built on my open browser wallet project by adding phone number onboarding and integrating a custom store

i also built the onchain merchant with offchain fulfillment api that the app integrates to offer airtime purchases

shoutout to @milosevicfritz for putting together all the non-technical docs!
