Account Abstraction
Quick Answer
Account abstraction is a blockchain upgrade that allows smart contracts to act as user accounts, enabling gasless transactions and simplified checkout without requiring customers to hold native gas tokens.
Full Definition
Account abstraction is a blockchain architecture upgrade that allows smart contracts to act as user accounts, removing the requirement for externally owned accounts (EOAs) to initiate transactions. It enables features like gasless transactions, session keys, social recovery, and batched operations. For crypto payments, account abstraction lets customers pay without holding native gas tokens — the merchant or payment provider sponsors the fee. This dramatically simplifies checkout. ERC-4337 is the leading account abstraction standard on Ethereum and EVM-compatible chains, and it is increasingly adopted by payment gateways to reduce friction at the point of sale.
