SÃO PAULO, Brazil, August 26, 2026 (EZ Newswire) -- According to research from McKinsey, global financial markets hold more than $400 trillion in assets, yet only a fraction of traditional financial activity has moved on-chain. The barrier is less about whether blockchain technology works and more about whether institutions can adopt it without giving up the privacy, control and compliance frameworks that they already rely on.
That trade-off has proven difficult to solve. Shared ledger consortium models provide one option, but they struggle to scale. Banks hesitate to share private data, transaction operations, or trading strategies on a common ledger. As a result, many institutions use traditional systems alongside smaller blockchain efforts, leading to manual and disconnected workflows.
Rayls Sovereign, launched by Rayls on August 25, 2026, closes the gap between control and connectivity by giving each financial institution its own private blockchain environment that integrates with its core internal systems, while maintaining connectivity to other institutional networks and public blockchains.
The open-source, EVM-compatible system operates within an institution’s existing technology environment, keeping data, keys, security and governance internal and under the organization’s control. The infrastructure brings financial activity on-chain without exposing sensitive information or requiring institutions to rebuild existing systems.
Private infrastructure, not an isolated network
The key distinction behind Rayls Sovereign is that privacy and sovereignty do not have to mean isolation.
Institutions use Sovereign to create and manage tokenized deposits, stablecoins, and digital assets in their private environment. Sensitive client information, balances and trading activity remain within the institution’s system, while only the minimal data or cryptographic proofs required to compliantly transact with their counterparties are shared externally.
This setup lets institutions transact with approved counterparties or link assets to public blockchain networks without exposing confidential information. The model maintains governance and privacy at the institutional level while allowing assets access to broader on-chain infrastructure when needed.
Built for existing financial infrastructure
Rayls Sovereign sits within the technology environment financial institutions already operate rather than requiring an entirely separate blockchain stack. The system connects with existing banking, treasury, custody and data management systems, while APIs and developer tools allow internal teams to integrate blockchain functionality into existing workflows without Web3 engineering expertise.
Rayls Sovereign is built for high institutional activity. It handles over 15,000 transactions per second with hard settlement finality in under one second, powered by Rayls Axyl, the platform's permissioned consensus layer. This supports high-volume payments, atomic delivery-versus-payment exchanges, and post-trade activities.
The platform is fully EVM-compatible. Developers can use familiar Ethereum and Solidity tools instead of learning a new system. This lowers the technical barrier for financial institutions to bring their products and workflows on-chain.
Production infrastructure behind Sovereign
While Rayls Sovereign is a new architecture, the technology behind it is already operating inside financial institutions.
The platform is an evolution of the Rayls Privacy Node, which has been used in production by major financial institutions for more than two years. Sovereign re-architects that infrastructure with higher transaction capacity, customizable governance, greater scalability, simpler deployment and deeper integration with existing financial systems.
Around 30 financial institutions have installed Rayls infrastructure, with Núclea and XP among those already operating in production.
Núclea, Brazil's largest payments financial market infrastructure, processes approximately $3.5 trillion in payments annually and has been a live client on Rayls since June 2024, using it for corporate receivables tokenization. XP also uses Rayls infrastructure for USDXP, its fully US dollar-backed stablecoin launched in March 2026.
Those deployments provide evidence that Rayls’ infrastructure can operate in production within major financial institutions, creating a foundation for broader adoption across additional institutions, asset classes and markets. Beyond its existing deployments in Brazil, Rayls was selected by Kinexys by J.P. Morgan for Project EPIC and has also worked with Mastercard on cross-border payments through its Start Path and Crypto Partner program.
The core Rayls Sovereign platform is open source, allowing banks and financial institutions to inspect, test, and deploy the infrastructure without being tied exclusively to proprietary software.
This is important in an institutional environment where technology often undergoes extensive internal security, compliance, and operational reviews before it reaches production. Institutions can access Rayls Sovereign through a public GitHub repository and a Rayls-managed sandbox, alongside technical documentation, demos and institutional case studies.
Additional performance and privacy capabilities, including Rayls Axyl and Enygma, are available as premium modules. These can be accessed and used for free during pre-production development, before institutions move into commercial production. This structure gives institutions a way to start testing the core infrastructure independently. They can add additional capabilities as deployments progress toward production.
From private systems to connected on-chain finance
Rayls Sovereign gives financial institutions the infrastructure needed to bring significant assets and transaction volumes on-chain while maintaining the governance, privacy and policy controls required within their existing businesses.
The technology behind the platform already has live institutional activity to build on. Núclea provides a production example for tokenized receivables, XP uses Rayls infrastructure for USDXP, and about 30 financial institutions have already installed the underlying platform.
Rayls Sovereign takes that infrastructure and gives each institution its own environment to operate within. For banks and financial market infrastructures that have faced a choice between closed private networks and more open public blockchains, this model offers another option: institution-controlled infrastructure for data, governance, and financial activity, with connectivity to broader on-chain markets when needed.
With production deployments already underway, Rayls Sovereign’s next phase will focus on broader adoption across financial institutions, asset classes and markets. The significance of the launch is that infrastructure already proven in institutional production is now being opened up for broader use.
From August 25, 2026, Rayls Sovereign will be publicly available for institutions to evaluate and deploy it seamlessly. Financial institutions can access the open-source platform, Rayls-managed sandbox, technical documentation and institutional case studies at rayls.com.
