SWIFT Explores Blockchain Future with Consensys and Major Banks for Real-Time Payments

Sep 30, 2025

2 min read

Global financial messaging giant SWIFT is embarking on a significant technological exploration, partnering with Ethereum software company Consensys and 30 major financial institutions. The collaboration aims to develop a blockchain-based prototype for real-time, 24/7 cross-border payments, potentially revolutionizing international transactions.

Key Takeaways

  • SWIFT is collaborating with Consensys and 30 financial institutions on a blockchain prototype.

  • The prototype focuses on enabling real-time, 24/7 cross-border payments.

  • It will utilize a secure ledger with smart contracts to record and validate transactions.

  • The specific Ethereum network (mainnet or Layer-2 Linea) for the prototype remains undisclosed.

A New Era for Cross-Border Payments

The SWIFT network, a critical infrastructure connecting over 11,500 financial institutions worldwide, is venturing into blockchain technology. This initiative, revealed at its Sibos conference, aims to extend SWIFT's role beyond its traditional messaging system to facilitate the direct movement of value across digital ecosystems. The prototype envisions a secure, real-time ledger that will record, sequence, and validate transactions between financial institutions, enforced by smart contracts.

Collaboration with Industry Leaders

Consensys, a prominent Ethereum software developer, is serving as the technology partner for this conceptual prototype. The project also boasts the involvement of 30 major financial players, including household names like Bank of America, Citi, Deutsche Bank, JP Morgan Chase, and Wells Fargo. This broad participation underscores the industry's interest in exploring decentralized solutions for traditional financial challenges.

Potential Impact on Transaction Volume

The implications of this partnership could be substantial. SWIFT currently processes approximately 53 million financial messages daily, representing a significant portion of global financial communication. If even a fraction of this volume were to be processed on-chain, it could dramatically increase the transaction throughput of blockchain networks. For instance, processing just 6% of SWIFT's volume on the Ethereum mainnet could double its current transaction capacity. The impact would be even more pronounced on Layer-2 solutions like Consensys's Linea, where a smaller percentage of SWIFT's volume could significantly boost its throughput.

Convergence of Traditional and Decentralized Finance

Consensys has highlighted this development as a pivotal moment, suggesting a convergence rather than a clash between traditional finance and decentralized finance. The prototype's exploration of a secure ledger with smart contracts indicates a move towards more efficient, transparent, and potentially faster cross-border settlements, leveraging the strengths of blockchain technology within established financial infrastructure.
