HIFI and Dfns are partnering to make money movement programmable, secure, and production-ready at scale.
The infrastructure that moves money is becoming as important as the money itself. For companies operating at the intersection of stablecoins, bank rails, and programmable finance, the wallet layer is a strategic decision that shapes how reliably, securely, and at what scale value can move.
Today, we are proud to announce that HIFI has chosen Dfns as its wallet infrastructure provider. This partnership puts one of the most ambitious stablecoin infrastructure platforms in the market on top of one of the most battle-tested wallet platforms in the industry and marks an important step in how programmable finance gets built at scale.
HIFI provides payments infrastructure for the internet economy
HIFI is not a payments company in the traditional sense. It is a composable API platform for teams that move money at scale, from two-person startups to Fortune 100 companies, built around the premise that money should behave like code.
At its core, HIFI is stablecoin infrastructure for developers. Its platform allows companies to move, convert, route, and compile value across stablecoins and bank rails through a single unified interface, removing the complexity that has historically made building programmable financial products prohibitively difficult.
The platform is organized around five capabilities that together form a complete financial stack:
- Inflows allow companies to accept deposits from banks, cards, and wallets, normalized into one model, with fees and settlement configured at entry.
- Outflows route payments to any destination through one interface, whether that is a bank account, a card, a wallet, or a stablecoin address across any supported network.
- Controls define what capital can do once it enters the system, approvals, limits, and custody restrictions built in by design.
- Workflows enable complex transaction logic: conditional transfers, escrow flows, multi-party routing, and multi-chain settlement across wallets and bank accounts.
- And Private Transactions give institutions the ability to settle between trusted partners with the discretion that regulated environments require.
The result is a platform that powers treasury automation, global payouts, marketplace settlement, liquidity routing, and instant conversion, programmatically. Companies rely on HIFI to move billions, orchestrate complex value flows, and scale financial operations into new markets and business models.
What makes HIFI particularly significant is the breadth of its reach and the seriousness of its compliance posture. With access to more than 130 countries and connectivity to over 10 billion endpoints on Visa’s network, HIFI operates at a scale that demands infrastructure partners who can match it. KYC, KYB, sanctions screening, and ongoing monitoring run natively inside the platform.
As a registered MSB with principal-agent bank partnerships, HIFI handles settlement and custody inside a regulated environment. Its partnership with Visa Direct, enabling stablecoins to move across Visa's global payments network, signals the direction HIFI is heading: deeply integrated into the institutional payment architecture of the world, not sitting alongside it.
Dfns is the wallet infrastructure layer for onchain finance
Dfns is the institutional wallet infrastructure platform that powers digital asset operations for fintechs and financial institutions all over the world. Since 2020, Dfns has helped companies manage digital asset operations and build applications onchain, offering a programmable wallet platform that brings together transaction lifecycle management, internal workflow orchestration, policy and governance controls, key management, and third-party service integration into one secure control plane. Today, Dfns is trusted by over 400 companies including Standard Chartered Bank, First Abu Dhabi Bank, IBM, Broadridge, Apex Group, Stripe, Kraken, Circle, Susquehanna, and many more.
The platform is built around four core products:
- Wallets-as-a-Service (WaaS) enables programmable wallet creation and management across 60+ blockchain networks, purpose-built for institutional-scale digital asset operations.
- Transaction Lifecycle Management (TLM) orchestrates the full transaction lifecycle across all supported networks, with deterministic nonce management, compliance integration, and end-to-end visibility.
- Wallet Entitlement Management (WEM) enforces who and what can access, approve, and control actions, wallets and transactions with granular governance, secure WebAuthn/FIDO2 authentication, multi-approval workflows, and programmable policies.
- Key Orchestration Service (KOS) delivers MPC- or HSM-based key generation, distribution, and signing, with native key import and export APIs that ensure institutions retain full ownership and portability of their signing material.
One of Dfns' most distinctive strengths is the breadth and depth of its chain coverage. For companies like HIFI that need to move value across the full landscape of relevant networks, this is foundational. Dfns supports all major chains where stablecoin and payment activity is concentrated: Ethereum, Solana, Bitcoin, Base, Polygon, BNB Chain, Stellar, Tron, and Hedera. But it also covers the institutional and permissioned networks that are becoming critical for regulated finance: Canton, Flow, Concordium, Tempo, and more, with new chains continuously added as the market evolves.
This depth of coverage is matched by a security posture that is among the most rigorous in the industry. Dfns holds SOC 2 Type II, ISO 27001, ISO 27017, ISO 27018, ISO 22301 as well as CCSS Level 3 certifications, and has been pentested and audited by Quarkslab, IBM, KPMG, Halborn, and Kudelski Security. It has maintained zero security breaches since inception, with 99.95% uptime.
For a platform like HIFI, which moves billions across stablecoins and bank rails and promises bank-grade security to its customers, choosing the right wallet infrastructure was not a checkbox. It was a critical architectural decision. Dfns' combination of programmability, chain coverage, security certifications, and institutional pedigree made it the right foundation to build on.
Next: HIFI inside Dfns Payouts and Payins APIs
This partnership does not stop at wallet infrastructure. The next step in the collaboration is the integration of HIFI directly inside Dfns' Payouts and Payins APIs, bringing HIFI's stablecoin and bank rail connectivity natively into the Dfns platform.
For Dfns clients, this means the ability to initiate and receive payments through HIFI's network, across stablecoins, bank accounts, cards, and wallets, directly from within the Dfns control plane, without having to build or maintain separate integrations. For HIFI customers, it means wallet-level security and governance controls wrapping every flow they move through the platform.
Together, the two platforms form something the market has been building toward: a complete, secure, and programmable layer for the internet economy, where money moves like code, keys are governed like infrastructure, and compliance is built in from the start, not bolted on at the end.
