SWIFT Partners with Banks to Revolutionize Cross-Border Payments Using Blockchain and Ethereum's Layer 2
September 29, 2025
SWIFT, the global financial messaging network, is collaborating with over 30 major banks and Consensys to develop a blockchain-based shared digital ledger aimed at modernizing cross-border payments.
This new system will leverage Ethereum's Layer 2 solution Linea, utilizing zero-knowledge cryptography to enhance transaction speed and privacy, and will focus on recording, validating, and enforcing rules via smart contracts.
The initiative is designed to enable real-time, 24/7 cross-border transactions, making international payments faster, cheaper, and more transparent, with early pilots targeting specific corridors.
Industry experts see this move as a way to reduce costs and increase transparency by disintermediating traditional payment processes, although regulatory and integration challenges remain.
The project could influence future regulatory frameworks by emphasizing compliance, security, and interoperability, setting new standards for digital asset transfers in regulated environments.
Success depends on overcoming challenges like scalability, cybersecurity, and regulatory harmonization, with widespread industry adoption being crucial.
Traditional banks and legacy payment infrastructure providers may face operational and revenue challenges if they do not adopt distributed ledger technology solutions.
This blockchain initiative responds to the rapidly growing stablecoin market, which could reach $4 trillion in circulation by 2030, and the increasing exploration of digital currencies by central banks.
The rise of stablecoins, with estimates of up to $4 trillion in circulation by 2030 and $100 trillion in annual trade, underscores the need for more efficient cross-border payment infrastructure.
Approximately 90% of the world's central banks are exploring digital versions of fiat currencies to stay competitive in the evolving financial landscape.
The ultimate goal is for members to use the network for transactions involving digital assets like stablecoins, tokenized deposits, and other tokenized assets, facilitating seamless digital value transfer.
The system aims to support the transfer of regulated tokenized assets across digital ecosystems, ensuring interoperability with existing and emerging networks.
