Swift’s blockchain is using an EVM compatible architecture based on Hyperledger Besu

The ledger MVP is being built on open-source foundations, using an Ethereum Virtual Machine (EVM)-compatible architecture based on Hyperledger Besu. It is designed to integrate with the broader digital asset ecosystem, forming a new layer within Swift’s infrastructure stack that combines the capabilities of distributed ledger technology with Swift’s global reach, security and standards. It lays the foundation for interoperability and scalability as the digital money landscape evolves.

Swift will operate the ledger, providing orchestration of transaction workflows, validation of funding commitments and coordination of interbank processes. Banks will operate their own environments and retain full authority over keys, assets, funding and settlement through RTGS systems, correspondent banking relationships or other agreed mechanisms between participants.
