JP Morgan is adopting a 'both/and' strategy for digital assets, utilizing its internal blockchain for client trades while exploring public blockchains such as Ethereum. The bank aims to integrate with Coinbase by 2026, enabling direct bank-to-wallet crypto trading services. Additionally, JP Morgan is considering future custody services, although these are not expected in the near term. This move reflects CEO Jamie Dimon's evolving stance on blockchain and a strategic shift towards decentralized finance.
