Mastercard expands nostro settlement to 9 blockchains — USDC USDG USDP RLUSD SoFiUSD now operational for intraday weekend and holiday settlement
Mastercard confirmed on June 3, 2026 the expansion of nostro settlement capabilities across 9 blockchain networks including Arbitrum, Base, Canton Network, Ethereum, Polygon, Solana, Tempo and XRPL — supporting five regulated stablecoins simultaneously. ARQ Finance, CBW Bank, Cross River Bank, Lead Bank and Nuvei are among the first to support the new nostro settlement infrastructure. The 24/7 intraday weekend and holiday settlement capability eliminates the traditional correspondent banking cut-off time constraint from nostro operations.

SWIFT advances blockchain ledger to MVP — 30 global banks enable real-time nostro settlement
SWIFT completed the design phase of its blockchain-based shared ledger with over 30 global banks including JPMorgan, HSBC, BNP Paribas, Deutsche Bank, and Bank of America — combining messaging and settlement into a single layer that gives banks real-time nostro settlement, better liquidity visibility, and drastically reduced reconciliation overhead 24/7.

Every bank that participates in cross-border payments maintains nostro accounts — foreign currency balances held at correspondent banks in dozens of countries simultaneously. These balances exist for one purpose: to fund international payments without waiting for interbank settlement to complete.
The cost is enormous. McKinsey estimates that banks collectively hold approximately $25 trillion in nostro account balances globally — capital that earns minimal returns while sitting idle, waiting for correspondent banking cycles to clear.
SWIFT’s blockchain ledger collapses the traditional cross-border payment process by combining messaging and settlement into a single layer — giving banks faster payment execution, better liquidity visibility, and drastically reduced reconciliation effort.
This is the structural transformation that nostrosettle.com/.eth addresses — the institutional namespace for the real-time nostro settlement infrastructure that SWIFT, JPMorgan, and 30 global banks are building simultaneously in 2026.
The Regulatory Foundation, The Nostro Settlement Architecture, and The Ecosystem
SWIFT advanced its blockchain ledger to Minimum Viable Product stage on March 30, 2026 — with the ledger recording, sequencing, and validating transactions between financial institutions using smart contracts, enabling tokenized deposits, regulated stablecoins, and central bank digital currencies to move across institutions in real time around the clock.
This is the most consequential infrastructure development for nostro settlement in decades — SWIFT is not building a parallel system but replacing the correspondent banking messaging layer with a blockchain settlement layer that eliminates nostro reconciliation overhead simultaneously.
Global cross-border payments are expected to exceed $320 trillion by 2032 — despite delays, high costs, and limited weekend availability that SWIFT’s new ledger directly addresses.
The Trump Executive Order of May 19, 2026 directed the Federal Reserve to evaluate direct payment access for crypto and fintech firms — creating a regulatory pathway for non-bank institutions to access Fed payment infrastructure directly, eliminating the correspondent banking intermediary that makes nostro accounts necessary for domestic USD settlement.
Payment systems and cross-border settlement platforms are increasingly experimenting with distributed ledger technology to achieve atomic settlement and continuous processing — reflecting a deliberate shift away from permissionless crypto networks toward permissioned, institutionally governed shared ledgers.
The GENIUS Act FDIC Proposed Rule of April 7, 2026 establishes stablecoin reserve requirements that directly govern the tokenized deposits and regulated stablecoins that flow through SWIFT’s new blockchain nostro settlement layer.
The Nostro Settlement Architecture
Traditional nostro settlement operates through a three-step process that creates the $25 trillion dead capital problem.
Pre-funding: banks must hold nostro balances in every currency corridor they operate in — anticipating payment volumes that may or may not materialize, creating systematic over-collateralization.
Reconciliation: every cross-border payment requires reconciliation between the sending bank’s records, the correspondent bank’s records, and SWIFT’s messaging records — a process that generates significant operational overhead and delay.
Settlement finality: traditional nostro settlement achieves finality only after correspondent banking cycles complete — typically T+1 or T+2, creating a window of counterparty exposure on every cross-border transaction.
SWIFT’s blockchain ledger enables 24/7 cross-border payments through tokenized commercial bank deposits — eliminating weekend delays. Banks can gain speed and visibility while maintaining complete control over keys, compliance, and settlement.
nostrosettle.com is the institutional portal for this transformation — the compliance identity, the nostro settlement brand, and the legal anchor for any bank building real-time nostro settlement infrastructure under the SWIFT blockchain framework and Trump Executive Order payment access guidelines.
nostrosettle.eth is the on-chain complement — an ENS-resolvable endpoint where nostro settlement attestations, reconciliation records, and cross-border payment documentation can be stored as immutable distributed ledger entries.
The Nostro Settlement Ecosystem
nostrosettle is the cross-border settlement core of the PillarsX settlement namespace. It connects directly to nostrosettlement.com/.eth — the legal documentation longform for nostro settlement regulatory filings — and to settlerails.com/.eth as the Fed-compatible settlement rails that domestic nostro operations connect to through the Trump Executive Order payment access framework.
Beyond the nostro cluster, nostrosettle integrates with instantdvp.com/.eth as the instant DVP finality standard that real-time nostro settlement requires, ppsigateway.com/.eth as the PPSI gateway that routes stablecoin-denominated nostro payments through the Federal Reserve payment system, and mcisettle.com/.eth as the BIS MCI-regulated settlement identity for the crypto intermediaries that participate in cross-border nostro settlement alongside traditional correspondent banks.
Global Settlement Network raised $11 million pre-seed at over $100 million valuation on May 6, 2026 — alongside $125 million in committed settlement liquidity — building infrastructure for regulated digital currency issuance, tokenized assets, and cross-border settlement without relying on fragmented settlement systems.
This $11 million raise at $100 million valuation for a cross-border nostro settlement infrastructure provider demonstrates the institutional capital flowing into this space — and validates nostrosettle as a Tier-1 namespace for the institutions building this infrastructure.
