DFNS now supports Rayls with full Tier-1 integration. This brings Rayls into the DFNS platform as a fully operational environment for banks, asset managers, and payment providers building tokenized deposits, real-world asset tokenization, and cross-border payment workflows, with the privacy and compliance institutions require and access to public chain liquidity, alongside the other public and private networks DFNS supports.
What is Rayls?
Rayls is an EVM-compatible Layer 1 blockchain designed for financial institutions, built to connect banks to blockchain liquidity with privacy and compliance built into the protocol. Where most public chains expose every transaction to the world, and most private chains cut institutions off from public liquidity, Rayls is built to do both: keep sensitive activity private and compliant while giving institutions a path to the liquidity of public networks. Its public chain mainnet launched on April 30, 2026.
Rayls originated from Parfin, the institutional digital asset infrastructure provider, and has been validated in some of the most demanding environments in the industry, including Banco Central do Brasil’s Drex program. The design goal is consistent: give regulated institutions an environment where tokenized deposits, tokenized assets, and payments can operate to the standards their boards, auditors, and regulators expect.
Key characteristics include:
- EVM Layer 1 built for institutions: full EVM compatibility, so developers build on Rayls with familiar Ethereum tooling such as Solidity rather than learning a new environment.
- Built-in privacy through Enygma: Rayls’ Enygma privacy layer combines zero-knowledge proofs and homomorphic encryption to enable shielded transactions across standard Ethereum token formats, without the need for a dedicated privacy chain.
- Sovereign Privacy Nodes: institutions operate within their own permissioned environments, where they can mint, transfer, and extend fiat deposits as EVM-standard tokens while preserving the bank’s balance sheet and control.
- A bridge to public liquidity: Rayls connects permissioned financial networks to public chain liquidity, so institutions are not cut off from public markets, supported by a LayerZero integration for cross-chain bridging.
- A three-layer architecture: tokenized deposits as the programmable foundation, yield-bearing asset vaults for the distribution of institutional assets, and cross-border payments and FX with private settlement in seconds rather than days.
- Compliance by design: built from the ground up for regulated institutions rather than retrofitted, with privacy and compliance treated as protocol-level properties.
- Institutional backing and ecosystem: backed by investors including Framework Ventures, ParaFi Capital, Valor Capital, and Tether, with an ecosystem spanning Banco Central do Brasil, the BIS, Accenture, Mastercard, Tether, and a growing set of institutional applications and validators.
Why DFNS and Rayls are a strong match for banks going onchain
An institutional network answers one question for a bank: where can my transactions settle, privately and compliantly, with a path to liquidity? It does not, on its own, answer the harder one: how do I actually operate financial products on that network with the controls my board, auditors, and regulators expect? That is the gap DFNS fills, and it is why this is more than a wallet integration.
DFNS is a core banking platform for digital assets, the control plane between a bank’s business logic and the networks it runs on. On top of any network it supports, including Rayls, DFNS provides:
- Wallet-as-a-Service as the account layer for custody, payments, treasury, and tokenization
- Transaction Management covering construction, simulation, broadcast, rebroadcast, and lifecycle tracking, not just signing
- Workflows that import a bank’s existing approval chains, triggers, and fallback paths
- Treasury and Tokenization modules for managing balances and servicing tokenized assets across their full lifecycle
- Policy Engine enforcing limits, allowlists, quorums, roles, and ABI-aware approvals before any signature
- Governance and compliance sitting directly in the execution path, with audit evidence regulators will accept
And critically, DFNS’ key management service works across MPC, HSMs including IBM, Thales, and Securosys, TEEs, and offline signers. It can be deployed as SaaS, hybrid, or fully on-premise, allowing each bank to align its signing and custody model with its own risk appetite, operating model, and regulatory requirements instead of being forced into a single fixed architecture.
Put together, the combination is clean: Rayls provides the institutional EVM network a bank settles on, with privacy and a path to public liquidity, and DFNS provides the core banking system that runs accounts, controls, approvals, and asset servicing on top of it. Because Rayls is EVM-compatible, institutions get the full depth of DFNS’ EVM support, from token standards and smart contract interactions to account abstraction and gas sponsorship, under one set of controls that extends across Rayls and every other network they operate. Two systems built to institutional standards, meeting where regulated finance is actually heading.
Full tier-1 support on DFNS
DFNS provides full tier-1 support for Rayls, giving institutions access to a complete, programmable infrastructure layer:
- Wallet creation: instant provisioning via API or dashboard
- Native transfers: send and receive native assets on the network
- Token transfers: support for tokens on Rayls, including tokenized deposits, stablecoins, and tokenized assets
- Smart contract execution: interact with onchain applications and financial workflows, including any contract via Bring Your Own ABI
- Transaction broadcast: submit transactions to the network
- Secure signing: operations run through DFNS’ key management with no single point of failure
- Balance retrieval: query balances across wallets

Use Cases
Rayls’ combination of EVM compatibility, built-in privacy, compliance, and a bridge to public liquidity makes it a strong environment for regulated financial workflows. Examples include:
- Tokenized deposits: mint, transfer, and service fiat deposits as EVM-standard tokens within a bank’s own privacy environment, governed end to end through DFNS
- Real-world asset tokenization: issue and service tokenized financial instruments with compliant wallet infrastructure, granular approval workflows, and privacy preserved
- Cross-border payments and FX: settle private cross-border transactions in seconds rather than days, with policy enforcement and audit trails built in
- Access to regulated liquidity: connect permissioned institutional activity to public chain liquidity without exposing sensitive positions
- Yield-bearing asset distribution: manage and distribute institutional assets to suitable investors under governed, auditable controls
For institutions that need privacy and compliance today and a path to public liquidity tomorrow, Rayls on DFNS gives one unified core banking layer across both.
Rayls joins 60+ blockchain networks supported on DFNS, powering digital asset operations for 400+ institutional clients worldwide.
