Accounts & Identities
An "account" is a fundamental concept in the IoTeX blockchain, represented by a pair of cryptographic keys: a private key and a public key, utilized to sign and verify blockchain actions.
IoTeX accounts could represent individual users, machines, or entities, facilitating interactions with the blockchain and dApps. Like Ethereum, IoTeX's architecture includes two types of accounts:
Externally Owned Accounts (EOAs): Controlled by private keys, these accounts represent individual users or entities.
Contract Accounts: These are associated with smart contracts deployed on the blockchain and operate based on their programmed logic. Each contract account maintains a balance, nonce, and storage, contributing to IoTeX's global state.

Account Abstraction
IoTeX supports Account Abstraction as defined by ERC-4337 v0.6.0.
"Account Abstraction (AA) allows users to use smart contract wallets containing arbitrary verification logic instead of EOAs as their primary account."
By enabling people to use Smart Contracts as their primary accounts, ERC-4337 introduces many user experience benefits.
ERC-4337 runs on top of the blockchain and does not require any changes to the blockchain itself. Currently, the IoTeX Account Abstraction code is based on ERC-4337 0.6.0 release version.
ioID Identities
The blockchain also supports ioID identities, providing a secure and verified identity system that integrates seamlessly with various DePIN projects and applications.
