Account Abstraction: Making Accounts Smarter
summary
Account abstraction is implemented today as ERC-4337 using a separate user operation mempool and relay nodes called bundlers that validate, batch and post operations so contracts can be full wallets without protocol changes. Live experiments (hackathon wallets like Soul and Proton, a Gnosis Safe module) show paymasters that let dapps or tokens sponsor gas, session keys, social recovery, BLS signatures, atomic/batched ops, and same-address deployments across L2s; works on any EVM chain and already executes without needing a hard fork.
