About the Axiom Keystore

The Axiom Keystore is a special-purpose ZK rollup which manages signing data for smart accounts across all other rollups. This gives users a single place to manage their keys and enables operations like key recovery and rotation to be done once and automatically applied for a user's smart accounts across all rollups. The design features:

  • Censorship resistance via L1 force inclusion

  • Fast finality via ZK verification

  • Ability to build key rotation policies in Rust

  • ERC-6900/7579 compatible modules for keystore-enabled smart accounts on OP Stack and Arbitrum Orbit

Our Private Devnet release consists of a keystore rollup settling to Sepolia and features:

  • Centralized node and sequencer with JSON-RPC API support for the keystore.

  • Keystore-compatible smart account validation module for OP Stack L2s.

  • Minimal SDK to enable integration into wallet frontends to transact on OP Stack L2s and on the keystore.

Axiom is working with a small group of smart account teams including Rhinestone to build keystore-enabled smart accounts. With Rhinestone, we are looking to help existing wallet providers transition to EIP-7702 smart accounts with built-in cross-chain account recovery.
