Kinto only allows transactions from account abstraction-powered wallets. Externally owned accounts (EOA) are disabled for greater security and to provide a uniform, delightful user experience.
To have a great user experience, Kinto has adopted the Account Abstraction standard with a few tweaks. As a result, users will receive the following benefits:
Have a non-custodial smart wallet that can be used like any web2 application
Don't have to worry about seed phrases or browser extensions
Don't have to pay for transaction fees and worry about gas settings
Safe and easy recovery procedures in case of loss
Kinto's account abstraction allows developers to focus on building their financial applications without worrying about the underlying infrastructure.
To facilitate the development process and increase the security of our implementation, we have made a few changes:
: Checks that the wallet belongs to a whitelisted wallet factory.
: In Kinto, end contracts must pay for user transactions and charge the users fees on deposit/withdraw/interest. We'll open a developer dashboard to help developers top up their contracts and ensure an interrupted service.
: Only users who have completed the KYC process can create valid AA wallets in Kinto.
: User Wallets have a minimum of one cloud non-custodial signer (Turnkey) and a maximum of three signers. Users can set up an authentication policy that fits their situation. In an emergency, a cloud recovery signer (Turnkey) can start an emergency process that needs to be ratified by the user.
: The factory to create and manage Kinto Wallets. It also facilitates contract deployments.
: The Kinto smart-contract wallet. The code contains the code that verifies the execution, recovery, and management of the wallet.
: Based on the EntryPoint of the original EIP-4337, the Kinto EntryPoint validates that a valid factory created the wallet.
: In Kinto, end contracts pay for the gas of its users. The sponsor paymaster handles the balance/funding of all contracts in the network.
