Base to introduce native account abstraction (EIP-8130) in the Cobalt upgrade this September

Foresight News reported that Base tweeted it will launch native account abstraction (EIP-8130) in the upcoming Cobalt upgrade this September. Base is collaborating with Optimism, a certain exchange, and WalletConnect to jointly promote the implementation of this standard across all EVM chains, and the OP Stack chains will follow later this year. Compared to existing smart account solutions (ERC-4337), EIP-8130 reduces USDC transfer gas consumption by 63.2% (from 125,000 down to 46,000), and transaction byte size by 83.4%. To facilitate early testing by developers, Base has introduced a temporary development network, Base Vibenet.

The core features of the Cobalt upgrade include three items: transaction fee sponsorship (allowing applications to pay gas fees on behalf of users), batch calls (merging multiple transactions into one), and session keys (authorizing applications to sign within a specific scope to reduce repeated confirmations). Additionally, EIP-8130 supports cross-chain account portability, anti-quantum authentication key rotation, parallel nonce, and sub-accounts.
