Composable Native Account Abstraction

pedrouid · August 27, 2026, 1:16pm

This thread covers three composable Core EIPs:

EIP-8398: Portable Account Keystore defining actors, authenticators, account configuration, creation, and portability.
EIP-8399: Basic native AA transaction using the EIP-8398 authority model, with batching, sponsorship, and keyed sequential nonces.
EIP-8400: Optional advanced controls adding policies, account locking, and nonce-free transactions using the same transaction envelope.

The separation keeps account authority independent from transaction transport while allowing chains to progressively support native and advanced functionality. EIP-8130 remains unchanged.

All feedback is welcome and please feel free to comment directly on the PR below

As its a contract, would the Portable Account Keystore be keylessly deployed?
