Externally Owned Account

An Externally Owned Account or EOA is what an Ethereum account that is controlled by anyone that has the private keys is called.

Broadly speaking, other blockchains will have the same concept, but may have differences on what is possible depending on the implementation.

This is in contrast to a smart contract.

Account Abstraction #account-abstraction is the label for moving away from “just” EOAs to more flexible smart contract wallets.
