  1. Core Concepts

Account Abstraction

Heima's account abstraction introduces a seamless identity layer centered on the omni-account, a unified user ID across all chains.

Instead of managing fragmented wallets and credentials, users interact with blockchain applications through a single, cross-chain identity.

Key features include:

  • Web2 + Web3 login support: Users can onboard via email, phone, passkeys, or social accounts, powered by partner authentication services.

  • Network-aware proxy mapping:

    • EVM chains: via EIP-7702 proxy contracts

    • Substrate chains: native proxy contracts

    • Non-native environments: TEE-backed secure proxy accounts

  • Delegated execution: Projected accounts can act on behalf of an omni-account with programmable, permissioned control.

  • Identity graph: Heima builds an internal graph to link user personas across apps and contexts, enabling personalization without exposing sensitive data.

This model reduces integration complexity for developers, eliminates key fragmentation, and enables secure, user-centric Web3 experiences built on a flexible identity framework.
