SWIFT launches blockchain ledger with 17-bank pilot

SWIFT Launches Blockchain-Based Shared Ledger – 17 Banks Begin Tokenized Deposit Pilots While Traditional Rails Remain for Settlement

Key Takeaways

• SWIFT has moved its blockchain-based shared ledger from testing into live deployment.
• Seventeen major banks across six continents are preparing to process pilot transactions using tokenized deposits.
• The system operates as an orchestration layer, while final settlement still occurs through SWIFT’s traditional correspondent banking network.
• The ledger is built on Linea, an Ethereum layer-2 network developed by ConsenSys, and remains fully permissioned.
• SWIFT connects more than 11,500 institutions, but the current pilot includes only 17 banks.

SWIFT Moves Blockchain Ledger Into Live Environment

SWIFT has transitioned its blockchain-based shared ledger from a testing phase to live deployment. The system is designed to support tokenized deposits issued by participating banks. According to SWIFT, 17 major banks are preparing to conduct pilot transfers using the new setup.

The participating institutions include Citi, HSBC, UBS, ANZ, BNP Paribas, BNY, DBS, First Abu Dhabi Bank, FirstRand Bank, Itaú Unibanco, Lloyds Bank, Mashreq, MUFG Bank, OCBC, Standard Bank, Standard Chartered, and UOB. These banks represent six continents and form the initial group testing real transactions on the ledger.

The ledger does not replace SWIFT’s existing infrastructure. Instead, it functions as an orchestration layer that coordinates tokenized deposit transfers between banks. The underlying funds only reach final settlement once they pass through SWIFT’s established correspondent banking and messaging network.

For users and institutions monitoring payment infrastructure developments, this distinction is central. While tokenized deposits can move around the clock, including overnight and on weekends, the legal and financial finality of each transfer still depends on the traditional rails.

Tokenized Deposits Aim to Improve Liquidity Visibility

Under the pilot model, banks issue tokenized deposits on their own systems. These digital representations of bank deposits are then transferred via the shared ledger. The design enables continuous movement of liquidity, but reconciliation and final settlement remain tied to SWIFT’s existing processes.

HSBC and Standard Chartered identified faster liquidity visibility and fewer reconciliation delays as key benefits for corporate clients participating in the pilot. The system was implemented in nine months and launched on a global scale from the start.

The timing reflects broader payment trends. According to J.P. Morgan estimates cited in the source material, cross-border payment volumes could increase from 194.6 trillion US dollars in 2024 to 320 trillion US dollars by 2032. This projected growth underscores why large financial institutions are exploring more efficient transaction models while maintaining established settlement frameworks.

For market participants evaluating infrastructure risk, the hybrid approach shows that SWIFT is testing blockchain-based coordination without removing its core settlement mechanisms.

Permissioned Architecture Built on Linea and Hyperledger Besu

SWIFT built the shared ledger on Linea, an Ethereum layer-2 network developed by ConsenSys. The system uses an EVM-compatible model based on Hyperledger Besu. Despite being connected to Ethereum-related technology, access to the ledger is fully permissioned.

Only members of the participating bank consortium can transact on the network. Governance and validator control remain within this closed group. This structure differs from public blockchain networks that rely on distributed and independent validators.

The permissioned design has drawn scrutiny because SWIFT executives have previously questioned the validator trust models of public networks such as the XRP Ledger. By keeping governance within a consortium, SWIFT avoids relying on open validator sets and instead retains centralized oversight among participating institutions.

More than 30 banks, including JPMorgan and Deutsche Bank, contributed to the design phase. The group was later narrowed to the 17 institutions now preparing to conduct pilot transactions.

Scale Remains Limited Compared to Public Stablecoin Rails

SWIFT’s global network connects more than 11,500 financial institutions. The current pilot, however, involves only 17 banks. This represents a small portion of SWIFT’s overall reach.

At the same time, public stablecoin rails are already facilitating round-the-clock transfers without requiring a bank consortium to build shared infrastructure. Coinbase has expanded its stablecoin payment reach through Nium, while MoneyGram has rolled out a dollar stablecoin on Stellar. Both operate as active payment rails.

In addition, a dirham-backed stablecoin in the United Arab Emirates reached exchanges this month. Institutions are also increasingly treating tokenized bonds and equities as potential product lines.

These parallel developments highlight that tokenized financial instruments and blockchain-based transfers are advancing across multiple models, including public networks and private consortia.

For users of crypto payment systems, including those assessing platforms that rely on stablecoins for deposits and withdrawals, the distinction between permissioned bank-led networks and public blockchain rails remains relevant. Public stablecoin transactions can move independently of correspondent banking systems, while SWIFT’s ledger still depends on its traditional infrastructure for settlement.

Our Assessment

SWIFT has formally moved its blockchain-based shared ledger into live deployment and begun pilot preparations with 17 major banks. The system enables tokenized deposit transfers on a permissioned network built on Linea and Hyperledger Besu, while final settlement continues through SWIFT’s existing correspondent banking framework. Although SWIFT’s overall network includes more than 11,500 institutions, the current implementation remains limited to a small consortium. At the same time, public stablecoin and tokenization initiatives continue to operate independently on open networks, creating parallel models for cross-border value transfer.
