- Google Cloud introduces a private Layer 1 called Universal Ledger for cross-border payments and asset settlement.
- CME Group pilots the system as Google positions GCUL against Ripple, Circle and Stripe offerings.
Google Cloud moved to challenge Ripple, Circle and Stripe by unveiling Google Cloud Universal Ledger, a private Layer 1 designed for cross-border payments and institutional settlement. The network is aimed at banks and payment service providers that require predictable fees, compliance controls and round-the-clock operations.
Google Cloud places GCUL in private testnet and advances pilot with CME Group
The platform is currently running in a private testnet as Google expands trials with partners. In March 2025, CME Group said it had completed the first phase of integration with GCUL and would test low-cost 24/7 settlement for collateral, margin and fee payments. That pilot frames the ledger’s immediate focus on wholesale money movements rather than retail transfers.
Google Cloud executives describe GCUL as a Layer 1 built for financial institutions, differentiating it from open public chains and from proprietary networks tied to individual payment companies.
The company’s materials emphasise programmability and integration with its cloud stack to facilitate tokenised assets and interbank settlement flows.
GCUL targets institutional settlement with Python-based contracts and neutral access
According to external briefings, GCUL supports Python-based smart contracts to reduce development friction for traditional engineering teams.
The network is positioned as permissioned and compliance-focused, with Google pitching “credibly neutral” access for competing institutions that may be reluctant to build on a rival’s proprietary chain.
The competitive backdrop is shifting as payment firms develop their own chains. Circle has announced Arc, an enterprise-oriented Layer 1 planned to support stablecoin payments, foreign exchange and capital market applications.
Stripe is working on Tempo, described as an Ethereum-compatible chain geared to high-throughput payment use cases. GCUL enters that landscape as an infrastructure layer rather than a vertically integrated network aligned to a single issuer or processor.
For banks and large PSPs, the immediate questions are throughput, interoperability and governance. Google’s documentation highlights atomic settlement for tokenised instruments and multi-currency support, which would be material for cross-border corridors where liquidity, finality and regulatory auditability must coexist.
The pilot with CME offers a path to production-grade testing across collateral and margin workflows that operate outside retail hours. Adoption will hinge on how participants evaluate operational controls, fee predictability and the ease of connecting existing treasury systems to Python-based contracts.
If those elements hold in broader trials, GCUL could sit alongside rather than replace existing rails by handling settlement and reconciliation while interfacing with card networks, real-time gross settlement systems and stablecoin issuers.
That approach mirrors market structure in which institutions select the ledger that best matches their counterparty set and compliance posture for each payment flow.
At the time of press, Bitcoin (BTC) is trading at $110,551.00, showing a gain of $465.00—equating to approximately a +0.422% increase from its previous close.
