According to online reports, the Society for Global Interbank Financial Telecommunications (SWIFT) previously disclosed that it is using the Ethereum L2 network Linea to test the on-chain messaging function. According to the latest news, BNP Paribas and Bank of New York Mellon (BNY) have begun to participate in the testing. The project currently involves "more than a dozen financial institutions." A source who declined to be named said that all testing work is expected to take several months to achieve, but it will bring important technological transformation to the international interbank payment industry.
