ChainThink News, July 20: According to a post on X platform by Base, Base will launch Native Account Abstraction (EIP-8130) as part of its Cobalt upgrade in September this year, and will advance the standard’s adoption across all EVM chains in collaboration with Optimism, Coinbase, and WalletConnect.

OP Stack chains are expected to follow later this year.

Base states that compared to existing smart account solutions such as ERC-4337, EIP-8130 can reduce gas consumption for USDC transfers by 63.2%, dropping from 125,000 to 46,000, and decrease transaction byte size by 83.4%.

To facilitate early developer testing, Base has launched a temporary testnet called Base Vibenet.

The core features of the Cobalt upgrade include transaction fee sponsorship, batch calls, and session keys, corresponding respectively to app-sponsored gas, merged multi-transaction execution, and application-level signing authorization within defined scopes.

Additionally, EIP-8130 supports cross-chain account portability, quantum-resistant key rotation, parallel nonces, and sub-account functionality.
