The main difference between Kinto and any other optimistic rollup is the existence of KYC requirements at the chain level. To send any transaction on Kinto, you must have gone through the KYC process through one of the approved providers and received the soulbond NFT called 'Kinto ID.'
Kinto implements the EIP-4337 for Account Abstraction. Kinto goes one step further and disables all Externally Owned Accounts. Users must create a non-custodial smart contract wallet to send transactions in the Kinto network.
