Currently, several international banks, including Deutsche Bank, UBS, and BBVA, are actively testing or applying blockchain, Rollup, asset tokenization, and Layer 2 scaling technologies, and are using these technologies as key tools to enhance efficiency, transparency, and compliance capabilities.

• Ethereum L2 and Rollup as mainstream solutions

Ethereum's Layer 2 (such as Rollup) and restaking technologies, due to their ability to balance speed, efficiency, and compliance, are particularly favored by institutional users. These technologies are regarded as the core of future financial infrastructure such as Web3, asset tokenization, and cross-border payments.

• Regulatory environment gradually clarifying

Emerging regulatory frameworks like the EU MiCA provide a legal basis for banks to adopt these blockchain technologies, reducing compliance risks and accelerating the practical deployment of financial institutions.
