Some of the Features to implement with Account abstraction:

Batch ERC20 transactions in one so no longer need approve , ideally in one click and no need to re-approve on metamask

Intent to Diminue the need for Conections - Signings - approvals at max (frictionless) since its still a bit annoying and takes too much steps/clicks

Ability to use our erc20 as "Gas Fees" example (1 erc20 for each transaction ) and we pay on behalf the gas fees in Matic.
