Swift's blockchain-based ledger, capable of settling cross-border tokenized-deposit transfers in minutes, will not be plug-and-play for the 17 banks now preparing live transactions on it. Each institution must first deploy a permissioned ledger, a digital-asset wallet, and tokenization and smart-contract capabilities to connect, according to Lamine Brahimi, co-founder and managing partner of custody and tokenization firm Taurus.

"If you want to connect today to the Swift ledger, you need three things," Brahimi said in an interview with CoinDesk. "You need your own permissioned ledger that interacts with that of Swift, you need wallet capabilities, and you also need tokenization and smart-contract capabilities to be able to integrate the Swift smart contracts."

What is Swift's ledger actually doing?

Swift has positioned its blockchain-based network as an orchestration layer, not a substitute for banks' internal systems or existing settlement arrangements. Final settlement continues through established infrastructure; Swift's network coordinates tokenized-deposit transfers across institutions and time zones. Deposits stay on bank balance sheets, distinguishing the model from stablecoins issued outside the banking system.

The messaging cooperative, which has dominated bank communication flows since the 1970s and presently moves up to $1.5 quadrillion annually, confirmed in July that 17 banks were preparing live tokenized-deposit transactions.

Who has gone live?

• HSBC and Standard Chartered completed the first live interbank transaction using Swift's ledger in August.
• DBS and Citi later executed a weekend cross-border dollar payment that settled in minutes rather than up to two business days.
• All four institutions demonstrated round-the-clock settlement, a structural shift from traditional correspondent banking schedules.

Is the infrastructure gap a weakness?

Brahimi, whose firm Taurus announced its Swift integration in August, said the three-layer requirement should not be read as a design flaw. He framed it as a structural reality of tokenized settlement rather than a barrier to adoption.

"I think it's a good move," Brahimi said. "That provides the choice."

The requirement does mean tokenized deposits remain a predominantly institutional product. Moving tokenized value between banks requires compatible standards and supporting systems on both sides, a coordination cost that has historically limited participation to the largest global institutions.

"Tokenized deposits until Swift's announcement were barely used," Brahimi said. "They were mostly used by huge banks like JPMorgan, because they had such a big global scale."

What does Taurus sell?

Taurus packages the three required components into a single platform: a permissioned ledger, wallet-management software, and tokenization and smart-contract tooling. Brahimi said competitors may require banks to stitch together multiple vendors to obtain the same functions.

The orchestration model preserves Swift's role as the coordinating messaging layer while pushing execution and custody responsibilities back to banks, a design that mirrors the cooperative's traditional position in correspondent banking.

What changes next?

The infrastructure burden raises a near-term question about how quickly mid-tier banks, lacking in-house tokenization stacks, will onboard compared with institutions such as HSBC and Citi, which already operate mature digital-asset divisions. Swift has not disclosed a deadline for broader bank participation beyond the 17 institutions currently in the preparation phase. Brahimi's comments suggest that adoption timelines will track each bank's existing digital-asset footprint rather than the readiness of Swift's network itself.
