The Society for Worldwide Interbank Financial Telecommunication (SWIFT) previously disclosed that it is using Ethereum's Layer 2 network, Linea, to test on-chain messaging capabilities. According to the latest news, BNP Paribas and Bank of New York Mellon (BNY) have begun participating in the test, and the project currently involves "more than a dozen financial institutions." An unnamed source said that the full testing is expected to take several months to complete, but it will bring a significant technological transformation to the international interbank payment industry.
