Rayls Sovereign · Available 25 August 2026

The onchain gateway for institutions

Rayls Sovereign is a private, institutional-grade blockchain that gives each financial institution its own sovereign ledger, integrated with existing banking and treasury systems and connected to external public and private blockchain networks.

Core banking on one side.
Onchain markets on the other.

Core banking

Traditional rails

  • Core banking
  • Treasury
  • Digital banking

Run in-house

Public chains

Onchain markets

  • Stablecoins
  • Vaults and yield
  • Global counterparties

Reached on the institution’s own terms

Between them an operational gap: manual workflows, trapped liquidity, no asset composability.

Two worlds, now connected

Rayls Sovereign installs on-prem alongside your institution's core banking, digital banking and treasury systems, and securely connects them with private and public blockchain networks.

Private

The institution

  • Mint and issue
  • Settle atomically
  • Govern and audit
Your instance

Rayls Sovereign

  • Sovereign ledger
  • API and CLI layer
  • Private bridge
Public

Onchain networks

  • Stablecoin settlement
  • Yield-bearing assets
  • Global liquidity

1

A sovereign ledger

Issue and settle tokenised assets on a private blockchain inside your own perimeter, with your data, your keys and your governance.

2

Connected both ways

Compliant bridges reach Rayls Private Networks and the Rayls Public Chain, when you choose and only then.

3

EVM-native end to end

One workflow from internal issuance to public distribution, running your existing Solidity contracts unchanged.

What institutions run on it

Tokenised deposits and stablecoins

Mint, transfer and collateralise deposit tokens on a blockchain the bank owns, and settle against external stablecoins with deterministic, sub-second finality.

Yield-bearing asset vaults

Tokenise privately at scale, then distribute compliantly into public-chain vaults with attestation-based access controls.

In production and building
with major institutions

Brazil's largest payment financial market infrastructure, in production on Rayls since June 2024, tokenising around 40,000 corporate receivables monthly.
Selected Rayls for the Drex CBDC pilot, in which 16 of Brazil's largest banks settled tokenised commercial bank deposits against central bank reserves, across six use cases explored on Rayls infrastructure.
Rayls was tested in Project EPIC as a privacy and identity layer for institutional tokenisation.
Selected Rayls for the Drex CBDC pilot, in which 16 of Brazil's largest banks settled tokenised commercial bank deposits against central bank reserves, across six use cases explored on Rayls infrastructure.
Caixa Económica Federal, Brazil's largest publicly owned bank, is moving into production on Rayls to tokenise real estate credit and its repayment cashflows, targeting Q3 2026.
One of Brazil's largest investment platforms, with around $400 billion in client assets, issues the USDXP stablecoin on Rayls.
Brazil's largest tokenised private credit issuer, committed to issuing $1 billion in real-world assets on Rayls by July 2027.

Customer testimonials

"USDXP proved that institutional-grade digital assets can run in production without compromising control or compliance. Rayls Sovereign extends that same principle further, giving highly regulated institutions like ours a dedicated environment to continue building."
Marcos Horie
Head of products, XP
"As Nimofast Global scales the tokenization of real-world energy and logistics assets, Rayls Sovereign gives us a dedicated environment where we set the rules — compliance, privacy, and governance on our terms — without disconnecting from institutional liquidity. This partnership is already moving real assets onchain."
Ramon Reis
President & CEO, Nimofast Global

Built for institutions

Performance

15,000+ TPS with sub-second finality, and horizontal scaling by adding internal nodes.

Integration

A complete API layer and CLI abstract the blockchain, so existing systems integrate without a Solidity team.

Security and custody

Halborn-audited consensus, and your own custody stack through the Cryptographic Trust Suite, including bring your own key.

Control

Protocol-level governance, role-based access control and single sign-on against your identity provider, and an immutable audit trail.

Operations

PostgreSQL data layer, Grafana monitoring, reversible upgrades, and an enterprise high-availability and disaster-recovery tier.

An open source EVM financial system, with premium modules

The open stack

Rayls is fully operational under Apache 2.0. Run it in production at no cost, inspect every line of source, install with one command, and prove it in your own environment before any commercial conversation.

The two premium modules

Axyl, a high-performance consensus, and Enygma, an EVM transaction privacy framework, are source-visible under the Business Source License 1.1. They are free to test, licensed in production, and convert automatically to Apache 2.0 four years after each release, so there is no lock-in to price in.

Questions institutions ask

Where does our data live, and what leaves the instance?

Rayls Sovereign is deployed inside the institution's own perimeter, on-premise or in a private cloud, behind its own firewall. Private data never leaves that instance, only the minimal payload required to complete a transaction is ever sent to an external network, and selective disclosure gives authorised parties access without exposing data to other participants.

Do we need blockchain engineers to run this?

No. A comprehensive API orchestration layer and standard CLI commands abstract the blockchain, so a standard implementation integrates with existing systems without a team of blockchain engineers or Solidity developers, while custom contracts and protocols remain fully available to institutions that want to build them.

How does the commercial model work?

Rayls is fully operational under Apache 2.0 and free to run in production. Axyl and Enygma are source-visible under the Business Source License 1.1, free to test and licensed in production, and each version converts automatically to Apache 2.0 four years after release. Licence and support are invoiced in the institution's local currency, and no cryptocurrency is needed to operate or to pay.

What performance and finality can we expect?

The Reth execution client with the Rayls Axyl consensus delivers 15,000+ transactions per second with sub-second deterministic finality, proven in testing, and additional internal nodes can be added for load balancing, high availability and operational resilience. Transactions on the sovereign ledger are gasless.

Which programmes and institutions has this been through?

Núclea has run corporate receivables on Rayls in production since June 2024, Banco Central do Brasil selected Rayls for the Drex CBDC pilot in which 16 of Brazil's largest banks settled tokenised commercial bank deposits against central bank reserves across six use cases, XP issues the USDXP stablecoin on Rayls, and Rayls was tested in Project EPIC by Kinexys by J.P. Morgan as a privacy and identity layer.

Can our security team inspect the code before we sign anything?

Yes. The open stack is Apache 2.0 and the premium modules are source-visible, so the code can be read in full. The Axyl consensus is audited by Halborn, key management is decoupled through the Cryptographic Trust Suite so an existing HSM, cloud KMS or bring-your-own-key stack plugs in, and the whole system can be installed and run in your own environment before any commercial conversation.
