Which banks are currently using AI technology in their services?

This question relates to traditional banking, not cryptocurrency. However, many banks are exploring blockchain and crypto technology. Some major institutions like JPMorgan Chase have developed blockchain networks for payments, while others offer cryptocurrency services to clients. In the crypto space, decentralized finance (DeFi) platforms use AI for risk assessment and trading. Traditional banks are still in early stages of AI integration for crypto services, primarily focusing on custody solutions and trading platforms. For crypto-specific information, you'd want to research exchanges and DeFi protocols rather than traditional banks.
