Swift is collaborating with major global banks, including BNP Paribas and BNY Mellon, to test the migration of its payment messaging system to blockchain technology. The selected network for this initiative is Linea, an Ethereum Layer 2 project developed by Consensys. Currently in the development phase, the project involves over ten financial institutions. According to sources, the project is expected to take several months to implement, aiming to transform the technology behind international interbank payment systems.
