# Differences with other rollups

### Kinto is an Optimistic Rollup

Kinto is an L2 built on the Arbitrum Nitro Stack. Its virtual machine is built by design to be identical to Ethereum EVM. However, there are a few unique differences you need to be aware of.

More details about these differences can be found in[ <mark style="color:purple;">the Arbitrum docs</mark>](https://docs.arbitrum.io/for-devs/concepts/differences-between-arbitrum-ethereum/overview)<mark style="color:purple;">.</mark>

### KYC and Kinto ID

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 soulbound NFT called 'Kinto ID.'

### Kinto and Account Abstraction

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.

You can read more about account abstraction [<mark style="color:purple;">here</mark>](/kinto-the-modular-exchange/building-on-kinto/rollup-features/kinto-account-abstraction.md).
