Announcing Parfin

Brazil-based Parfin has selected Dfns to power the wallet infrastructure behind its institutional Digital Assets platform. The decision reinforces a position Parfin has held publicly for some time: for regulated financial institutions operating tokenization, stablecoin, and on-chain settlement workflows, wallet infrastructure is not a back-office detail. It is the financial control layer that determines what can actually be deployed in production. Custody, signing authority, transaction policy, and audit trails have to integrate cleanly with the risk, compliance, and treasury systems institutions already run. By choosing Dfns, Parfin is treating wallets the same way it treats every other piece of its stack: as critical financial infrastructure, built to institutional standards from day one.

Parfin, building the digital asset infrastructure for institutional finance

Founded in 2019 and headquartered between Rio de Janeiro, São Paulo, and London, Parfin is the leading digital asset infrastructure provider in Latin America. The company builds modular infrastructure that connects traditional finance with on-chain markets, covering custody, tokenization, trading, asset management, and settlement for banks, broker-dealers, exchanges, and financial market infrastructures.

The client base reflects the depth of that positioning. Parfin works with major Brazilian banks, the Brazilian stock exchange ecosystem, broker-dealers, and crypto-native companies operating under strict regulatory oversight. The company was a core participant in the Banco Central do Brasil's Drex pilot, the country's tokenized real project, and a finalist in the G20/BIS CBDC Techsprint with privacy infrastructure already in production at scale. Parfin has also collaborated with Santander on tokenized real estate and vehicle transactions under the Banco Central's Lift Challenge, and Rayls was selected by Kinexys by J.P. Morgan to participate in Project EPIC, exploring privacy and identity solutions for financial institutions.

At the centre of the stack is Rayls, an institutional EVM blockchain designed to combine privacy, scalability, regulatory alignment, and interoperability between permissioned financial networks and public DeFi. 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. Around Rayls, Parfin operates a unified platform for digital asset custody, tokenization, and management, already processing meaningful stablecoin volume for institutional clients and supporting tokenized financial assets in live environments.

Parfin's strategy is grounded in execution under regulation: building infrastructure that lets traditional financial institutions participate in on-chain markets without compromising on compliance, privacy, or operational controls. Wallet infrastructure is foundational to that thesis, and the choice of partner reflects the same standard.

How Dfns supports Parfin's institutional Digital Assets platform

Dfns provides an orchestration layer with a Wallets-as-a-Service platform built for institutional and enterprise use. It is designed to deliver clear control, operational visibility, and consistent security across the entire wallet lifecycle, which matters in environments where auditability, internal controls, and regulatory expectations are non-negotiable.

For Parfin, the practical implication is that wallets become governed financial objects, not opaque cryptographic endpoints. Access rights, signing authority, and operational roles are defined and enforced at the infrastructure level, allowing Parfin to align wallet operations with the approval flows, segregation-of-duties models, and policy frameworks already used by its institutional clients. Policy-based transaction execution applies familiar thresholds, limits, and approval workflows directly on live networks, without rebuilding controls at the application layer. The platform separates application logic from key management and signing, which reduces operational risk and simplifies the security reviews and compliance audits that banks, broker-dealers, and FMIs run on a recurring basis. And the infrastructure is designed to scale across chains, asset types, and transaction volumes without weakening control or audit guarantees.

By relying on Dfns for wallet infrastructure, Parfin avoids the cost and complexity of building and maintaining cryptographic systems internally. Engineering effort can stay focused on what differentiates Parfin's platform: Rayls, tokenization workflows, privacy primitives, and institutional integrations, on top of a proven infrastructure layer for key management, transaction execution, and resilience.

A practical foundation for LatAm digital asset finance

Latin America is one of the more interesting regions in institutional digital assets right now. Stablecoin volumes across the region continue to grow. Regulators are formalising frameworks for tokenized deposits, asset tokenization, and digital currencies in parallel. The institutions that succeed in this environment will be the ones with infrastructure that holds up under regulatory scrutiny and at production scale, not the ones that retrofitted controls after launch.

Together, Parfin and Dfns offer a credible path to deployment for that environment: focused on execution, governance, and long-term reliability rather than experimentation. As tokenization and stablecoin rails continue to scale across the region, the combination of Parfin's regulated infrastructure and Dfns' bank-grade wallet platform gives institutions a deployment-ready foundation.
