Base's August core updates introduced native Account Abstraction (ERC-4337) at the protocol level. While mainstream media is fixated on retail UX improvements like gasless transactions, the actual macroeconomic value lies in corporate custody solutions.

Smart accounts allow funds to hardcode complex multi-signature logic, daily withdrawal limits, and role-based access controls directly into smart contracts. Hedge funds that previously shunned on-chain operations due to private key management risks can now natively integrate their internal compliance engines into L2 wallets.

This capability is projected to be the primary catalyst for migrating corporate fiat treasuries into stablecoins in Q4 2026.
