​
Summary

  • Introduce native account abstraction (EIP-8130): accounts configure authorized actors and signature validation onchain, so smart accounts send ordinary transactions
  • Apps get portable smart accounts, scoped session keys, atomic batching, and native gas sponsorship without bundler or relay infrastructure

​
Activation Timestamps

Cobalt has not been scheduled on mainnet or Sepolia. EIP-8130 is experimental and currently runs only on the vibenet devnet.

​
Required Software

Node software requirements will be published here once Cobalt is scheduled. To follow along today, connect to vibenet.

​
Native Account Abstraction (EIP-8130)

Cobalt brings account abstraction into the protocol. An account registers who can act for it, and how its signatures are checked, in an onchain system contract. The chain validates each transaction against that configuration, so smart accounts work without bundlers, relays, or a separate mempool.
