This is an example of using 'smart accounts' -- smart contracts owned by an end-user wallet letting the user perform multiple actions to different contracts in a single transaction.
The end-user owned smart contract is src/SmartAccount.sol. This contract is a modified version of prb-proxy. (See changelog in the contract file).
The example flow can be found in src/test/SmartAccount.t.sol. The tests enact the following high level flow: the end user mints
some ERC20 and ERC721 tokens (two actions on two different smart contracts) within a single transaction. The application developer or
end user can choose whether the assets remain in the end-user owned/controlled smart contract wallet, or in the end-user's owned wallet.
The tests are written using the foundry/forge testing framework. All setup information for foundry/forge can be found here.
To run tests:
forge build
then:
forge test --match-contract SmartAccount
