SWIFT and Major Banks Build Ethereum-Compatible Network

Global banking giants including J.P. Morgan and Citi collaborate with SWIFT on a blockchain-based settlement prototype for tokenized assets.

A conceptual prototype is currently under development by Consensys, suggesting an architecture compatible with Ethereum.

What is Being Built

The initiative does not replace existing SWIFT infrastructure but rather complements it. The shared ledger will serve specific categories of operations where blockchain settlement offers distinct advantages—24/7 payments between banks and the transfer of tokenized assets across different digital ecosystems.

Smart contracts will record, validate, and enforce regulatory requirements directly within the execution logic. This is a critical element: an instant settlement payment lacking sanctions control represents a greater risk than a slow but correctly processed payment. Integrated compliance makes the system viable within a strictly regulated banking environment.

Key Participants

Participating institutions include BNY Mellon, HSBC, J.P. Morgan, Citi, Deutsche Bank, Standard Chartered, and Bank of America. This group covers multiple currencies, jurisdictions, and central hubs of correspondent banking. Such a concentration of participants creates a network effect that smaller initiatives struggle to achieve.

BNY Mellon has identified the project as a strategic opportunity for 2026, highlighting the potential not only to accelerate payments but also to improve collateral management. The instantaneous movement of tokenized collateral between global custodial structures could significantly reduce operational costs.

Technological and Infrastructural Context

With Consensys developing the prototype, the project leans toward an ETH-compatible architecture and potential interoperability with existing enterprise solutions. Previous tests involved using Chainlink to connect public and private blockchains, reinforcing integration with the broader tokenization infrastructure.

The SWIFT initiative fits into a larger trend: central banks, regulators, and leading financial institutions are building compatible digital payment rails from various angles—ranging from central bank money settlement to trade finance and correspondent banking.

Implications for the Financial System

The significance of this project is not merely that blockchain settlement exists—it is already a reality on a limited scale. More importantly, the institutions that traditionally dominate international banking infrastructure are actively building its next version.

The transition from prototype to pilot and large-scale implementation will take years. However, when participants with the largest market shares and heaviest regulatory obligations join such an initiative, it signals that the transformation of financial infrastructure is entering a phase of institutional deployment rather than experimentation.
