🚨 Breaking News 🚨

@IBM launches a new blockchain wallet offering, and it’s powered by @dfnsHQ.

After years of building behind the scenes, we’re thrilled to announce that enterprise tech giant IBM has chosen to whitelabel Dfns for their new digital asset platform offering.

🏛️ IBM is one of the greatest institutions of the modern world.

Roughly 70% of the world’s transactions go through IBM mainframes 🤯

For over a century, they’ve shaped how the world computes, transacts, and secures its data.

So when IBM decides to make blockchain a strategic priority for their core infrastructure, LinuxOne and IBM Z, they’re not following the trend. They’re setting it.

And that changes everything.

“With IBM Digital Asset Haven, our clients have the opportunity to enter and expand into the digital asset space backed by IBM’s level of security and reliability. This new, unified platform delivers the resilience and data governance they have been asking for, empowering governments and enterprises to build the next generation of financial services.” — Tom McPherson, General Manager of IBM Z and LinuxONE.

Over the past year, Dfns and IBM worked side by side to merge cryptography, engineering, security, compliance, and infrastructure into one coherent stack, a platform we now call IBM Digital Asset Haven.

At its core lies Dfns:

✅ Wallets-as-a-Service (WaaS) unifies wallet operations across all chains, assets, users, and orgs through one secure interface.
✅ Transaction Management Service (TMS) automates routing, signing, monitoring, and settlement across 50+ public and private networks.
✅ Wallet Entitlement Management (WEM) centralizes access control, compliance checks, policy enforcement, and approvals with configurable multi-party workflows.
✅ Third-Party Integrations enables faster deployments and efficient operations with pre-integrated apps for exchanges, treasury, payments, compliance, and market data.
✅ Key Deployment Service (KDS) enable key orchestration from one interface using either Dfns’ MPC and/or IBM’s HSM, with secure enclaves for regulated offline storage and quantum-safe support.

📅 IBM Digital Assets Haven is expected to be available as SaaS and Hybrid SaaS in Q4 2025 and is planned for on-premises in Q2 2026.

For Dfns, this milestone is one of the biggest accomplishments in our history. For the industry, today’s announcement is concrete evidence that blockchain has now joined the core stack of finance.

And it’s just the beginning. Thank you to everyone who has contributed to making this happen 🙏

🟢 @dfnsHQ now supports staking on the @XDCNetwork.

Institutions holding XDC can now put it to work, earn rewards, and keep full custody and control.

XDC is an EVM-compatible Layer 1 built for enterprise use, with a focus on trade finance and real-world asset tokenization.

With staking support on DFNS, institutions can now stake and unstake XDC through the same transaction lifecycle they already use for every other operation.

That means:
✔️ The Policy Engine applies before anything is signed
✔️ Approval quorums, roles, and limits are enforced by default
✔️ Staking and unstaking become controlled, auditable decisions
✔️ Teams get visibility into balances, rewards, and activity

No separate staking infrastructure. No exposed private keys. No unmanaged actions outside the institution’s control framework.

Staking becomes one more operation inside DFNS, alongside holding, moving, and servicing assets across XDC and every other network you run.

That is what a core banking platform for digital assets is for.

🚨 What happens to your assets if your infra gets breached?

For most vendors, that's a very uncomfortable question. Not for @dfnsHQ.

Today, we’re introducing 𝗩𝗮𝗹𝗶𝗱𝗮𝘁𝗶𝗼𝗻 𝗚𝗮𝘁𝗲 ✨

It’s a final checkpoint for every action that runs inside your infrastructure (not ours).

DFNS already enforces policies before anything is signed: approval quorums, limits, allowlists, screening. For most institutions, that's exactly the control they need.

But those checks run inside DFNS infrastructure. So the most security-minded institutions ask:
𝘸𝘩𝘢𝘵 𝘪𝘧 𝘋𝘍𝘕𝘚 𝘪𝘵𝘴𝘦𝘭𝘧 𝘪𝘴 𝘤𝘰𝘮𝘱𝘳𝘰𝘮𝘪𝘴𝘦𝘥?

Validation Gate closes that gap.

It gives you a last check, performed on your own infrastructure, right before a signature is produced. Even if an attacker reached the signing layer directly, you can detect the request and stop the signature.

Because the check runs inside your own environment, it doesn't depend on DFNS being intact.

It doesn't replace our Policy Engine. It complements it.

Rich, business-level policies can live inside DFNS, while a final, sovereign checkpoint at the moment of signing runs inside your infrastructure that we cannot touch.

For an institution whose mandate is to trust no single party with its assets, that's the difference between a strong control model and a complete one.

🟢 Available now for both MPC and HSM-based deployments, on-premise or hybrid.

🆕 DFNS now supports @movement_xyz

$685 billion moves across borders every year. Most of it still takes 3–5 days to settle.

Stablecoins have now reached $265 billion in circulation. The asset layer is here. The next requirement is a settlement layer fast enough to move digital dollars at institutional scale.

Movement is built for that purpose: fast, low-cost settlement with finality. But for institutions, settlement speed is only one part of the equation.

Production requires accounts, controls, workflows, audit logs, secure signing, and policy enforcement across the full transaction lifecycle.

That is where @dfnsHQ comes in ✨

On top of Movement, and across every network we support, DFNS provides the operating layer institutions need to run financial products in production:

✔️ Transaction management from intent to finality
✔️ Treasury and tokenization to manage balances and service assets

A freelancer in Manila earns $5,000 from a US client 🇺🇲→ 🇵🇭

Her local bank takes up to 8% to receive it…

@SmashPayX fixes that. And they're building it on @dfnsHQ.

SmashPay is a USD account for the people the traditional system serves the worst: freelancers, remote workers, and distributed teams who earn in dollars but live outside the US.

Stablecoins are the rail underneath, the way ACH sits under a payments app.

That's where DFNS comes in ✨

For a product like this, the layer that holds balances, moves money across rails, and enforces the controls a regulated business needs isn't a back-office detail.

DFNS gives SmashPay that layer as one system:

✔️ A wallet for every user, provisioned invisibly to smooth the experience.
✔️ The transaction processing behind multi-rail sends and batch payouts.
✔️ Treasury tooling to manage USD balances.
✔️ Policy and governance that screen and approve before anything moves.

This is what onchain core banking platform is for.

Welcome to DFNS, SmashPay. 🤝

🟢 @dfnsHQ now supports @circle's CCTP.

USDC is issued on many chains. But sometimes you need to move a dollar between chains.

Today, moving USDC across chains usually means leaving your platform…

Bridging through a third-party UI, holding native gas on the destination to claim it, accepting a wrapped version instead of real USDC, waiting on unpredictable finality, and so forth.

For an institution, that's custody exposure to a bridge and a workflow you can't govern or automate.

We removed all of it ✨

With one API call from a source wallet, USDC now moves natively across chains and lands in a destination wallet on DFNS.

Across EVM to EVM, EVM to Solana, and Solana to EVM.

𝘞𝘰𝘳𝘵𝘩 𝘯𝘰𝘵𝘪𝘯𝘨: cross-chain moves follow the same DFNS transaction lifecycle. Approvals, limits, allowlists, and screening happen before signing, so USDC movements across chains remain controlled, auditable, and inside your policy framework.

⏭️ Next: deeper Circle support, with USDC minting into DFNS wallets.

[Finternet @Finternetasia]

Why does Asia prioritize API-first?

Felix Eigelshoven, Head of APAC & Global Partnership Strategy lead at @dfnsHQ explains 👇

[DFNS @dfnsHQ]

Payments company @stables_money has chosen @dfnsHQ 🖊️ ☑️

Stables is building something hard: one API to collect, convert, and move money across Asia and MENA.

What used to take five banking vendors stitched together, collection, conversion, settlement, compliance, Stables delivers in a single integration a developer can ship in an afternoon.

The scale is already real:
→ $2B+ in annual USDt volume
→ 160+ markets
→ Under 1h to settle on average
→ 99.99% uptime, SOC 2, FATF travel rule, PCI-DSS

Stables moved from Fireblocks to DFNS for reasons that map directly to running payments at scale:

✔️ 𝗔𝗻 𝗔𝗣𝗜, 𝗻𝗼𝘁 𝗮 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱 𝘄𝗶𝘁𝗵 𝗮𝗻 𝗔𝗣𝗜 𝗮𝘁𝘁𝗮𝗰𝗵𝗲𝗱. Every capability is programmable. Integrate once, access everything, automate your flows, add corridors by configuration.

✔️ 𝗥𝗲𝗹𝗶𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗮𝘁 𝗽𝗮𝘆𝗺𝗲𝗻𝘁𝘀 𝘀𝗰𝗮𝗹𝗲. A failed payment isn't a retry, it's a lost client. DFNS runs its node infra companies like Stripe rely on for thousands of daily transactions at near-zero failure rates.

✔️ 𝗣𝗿𝗶𝗰𝗶𝗻𝗴 𝘁𝗵𝗮𝘁 𝘀𝗰𝗮𝗹𝗲𝘀 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀. No fees on assets under custody, no cut of transaction volume. We're a technology provider, not a financial institution.

DFNS, as their new core wallet layer, enables Stables to focus on what makes them uniquely valuable: virtual accounts, quote-first transfers, embedded compliance, and AI-operated payments.

Proud to power you, Stables. 🤝

⟠ @ethereum

The second post in our network series.

If Bitcoin proved value could move without an intermediary, Ethereum proved the rules around value could be written in software.

It's the network most onchain finance actually runs on. Stablecoin settlement, tokenized funds and treasuries, onchain credit, exchange operations, and most of DeFi. And it just crossed a threshold Bitcoin structurally can't.

Spot Ether ETFs drew roughly $9.6B in net inflows in 2025. Then the category did something a Bitcoin ETF cannot: it started paying a yield. After the SEC, joined by the CFTC, ruled in March 2026 that staking is not a securities transaction, @BlackRock launched a staked-ETH ETF. The underlying asset is productive.

So for an institution, the question is no longer whether to engage with Ethereum. It's how to operate on it.

Holding ETH is custody of an asset. Issuing a stablecoin, servicing a tokenized fund, running an exchange's deposit and withdrawal flows, managing collateral, that is running financial products. It takes accounts, approvals, treasury controls, compliance screening, and an audit trail a regulator will accept.

That’s where DFNS comes in.
Our core banking platform helps you operate on Ethereum.

We sit between your business logic and Ethereum itself. Accounts, transactions, treasury, issuance, policy, governance, keys, and nodes, through one interface, across Ethereum and all EVMs.

So we wrote the institutional guide to Ethereum to help you take the first step. How it works, the EVM capabilities we support, the cryptography behind every transaction, the use cases, and where the network is going next.

🆕 DFNS now accepts inbound assets through one operation.

On many chains, a wallet can't just receive an asset. It has to opt in before it can hold it.

Send USDC to a wallet that hasn't opted in, and the payment simply fails ⛔

Every chain does this differently:
@CantonNetwork → 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗽𝗿𝗲𝗮𝗽𝗽𝗿𝗼𝘃𝗮𝗹
@StellarOrg → 𝗖𝗵𝗮𝗻𝗴𝗲𝗧𝗿𝘂𝘀𝘁 (𝗮 𝘁𝗿𝘂𝘀𝘁𝗹𝗶𝗻𝗲)
@XRPLF → 𝗧𝗿𝘂𝘀𝘁𝗦𝗲𝘁 (𝗮 𝘁𝗿𝘂𝘀𝘁𝗹𝗶𝗻𝗲)
@Algorand → 𝗮𝘀𝘀𝗲𝘁 𝗼𝗽𝘁-𝗶𝗻
@hedera → 𝗧𝗼𝗸𝗲𝗻𝗔𝘀𝘀𝗼𝗰𝗶𝗮𝘁𝗲

That's five different mechanisms to implement and maintain, just to let wallets hold assets.
We unified them into one.

With a single operation, 𝘈𝘤𝘤𝘦𝘱𝘵𝘐𝘯𝘣𝘰𝘶𝘯𝘥𝘈𝘴𝘴𝘦𝘵, @dfnsHQ constructs the right transaction for each chain, signs it, and broadcasts it. You provide the asset, we handle the per-chain mechanics.

For institutions, it's the prerequisite that makes inbound token transfers and distribution actually land. And it's controlled like any other transactions, so which wallets can hold which assets stays auditable.

🟢 @dfnsHQ now supports HashSphere.

HashSphere is @hashgraph's private, permissioned network built with @hedera technology.

It’s designed for institutions that need both the control of a private ledger and Hedera-grade performance.

✔️ Permissioned by design, limited to verified institutions
✔️ Data residency, privacy, and internal governance
✔️ EVM compatibility and core Hedera services
✔️ Public interoperability with Hedera mainnet

But a permissioned ledger only answers one question for a bank:
𝘸𝘩𝘦𝘳𝘦 𝘥𝘰 𝘮𝘺 𝘵𝘳𝘢𝘯𝘴𝘢𝘤𝘵𝘪𝘰𝘯𝘴 𝘴𝘦𝘵𝘵𝘭𝘦, 𝘱𝘳𝘪𝘷𝘢𝘵𝘦𝘭𝘺 𝘢𝘯𝘥 𝘤𝘰𝘮𝘱𝘭𝘪𝘢𝘯𝘵𝘭𝘺?

It doesn't answer the other half of it:
𝘩𝘰𝘸 𝘥𝘰 𝘐 𝘳��𝘯 𝘧𝘪𝘯𝘢𝘯𝘤𝘪𝘢𝘭 𝘱𝘳𝘰𝘥𝘶𝘤𝘵𝘴 𝘰𝘯 𝘪𝘵, 𝘸𝘪𝘵𝘩 𝘵𝘩𝘦 𝘤𝘰𝘯𝘵𝘳𝘰𝘭𝘴 𝘮𝘺 𝘣𝘰𝘢𝘳𝘥, 𝘢𝘶𝘥𝘪𝘵𝘰𝘳𝘴, 𝘢𝘯𝘥 𝘳𝘦𝘨𝘶𝘭𝘢𝘵𝘰𝘳𝘴 𝘦𝘹𝘱𝘦𝘤𝘵?

That's the gap DFNS fills.

HashSphere is the network a bank settles on. DFNS is the core system that runs on top. Two systems built to institutional standards, meeting where regulated finance is heading.

HashSphere joins 60+ networks on DFNS, powering 400+ fintech and institutional clients globally.

⏱️ @solana transactions expire after ~90 seconds.

For retail, that's fine. For institutions, it can break everything.

Airgapped signing takes longer. Multi-party approvals take longer.
Even a retry queue can blow past the window.

The result: institutions couldn't operate Solana the way they operate every other chain.

But as of today, they can ✅

@dfnsHQ now supports 𝗗𝘂𝗿𝗮𝗯𝗹𝗲 𝗡𝗼𝗻𝗰𝗲𝘀 on Solana.

One single flag at construct time and the transaction never expires. DFNS provisions, pools, reserves, and advances nonce accounts behind the scenes.

What this unlocks:
✔️ Offline and airgapped signing through DFNS Offline Signer or IBM OSO
✔️ Approval flows that take minutes, hours, or days
✔️ Resilient retries, no more blockhash aging out mid-process
✔️ Scheduled transactions you can submit at the right moment

🔵 DFNS now supports @arc on testnet

Arc is @circle's enterprise-grade public Layer 1, purpose-built for financial markets and payments.

What makes Arc different:
✔️ USDC as native gas, predictable, dollar-denominated fees
✔️ Full EVM compatibility with familiar tooling
✔️ Sub-second finality
✔️ StableFX, a built-in FX engine for real-time stablecoin conversion
✔️ Opt-in privacy with auditability preserved
✔️ Native Circle integration: USDC, EURC, USYC, CCTP, Gateway, and CPN

But settling on the right chain is only half the equation.

Running financial products on it, with the controls a board, auditor, and regulator expect, is the other half.

That's @dfnsHQ.

On Arc, institutions get the full DFNS platform
→ Wallet-as-a-Service, Transaction Management, Treasury Management, a Tokenization Engine, a Policy Engine enforcing quorums and approvals before every signature, a Governance Engine for verifiable zero-trust control, node connectivity, Node Management across 60+ blockchains, and Key Management across MPC, HSM, and Offline Signers.

All under DFNS' zero trust architecture, SOC 2 Type II and ISO 27001, trusted by 400+ clients globally.

Build, test, and validate your integration now, with a clear path to production when Arc goes live.

Introducing the 𝗚𝗼𝘃𝗲𝗿𝗻𝗮𝗻𝗰𝗲 𝗘𝗻𝗴𝗶𝗻𝗲 👁️

In blockchain infrastructure, every vendor asks you to trust them somewhere.

Even with MPC, HSMs, TEEs, SOC 2, and the rest of the modern security stack, there is often one hidden root of trust left inside the provider’s environment: 𝘨𝘰𝘷𝘦𝘳𝘯𝘢𝘯𝘤𝘦.

The system that decides who can sign, which policy applies, which approvals are required, and which wallet is in scope still lives in the vendor’s infrastructure.

A malicious insider, compromised admin, or supply-chain attack can tamper with that state. And once the state is corrupted, the cryptography downstream will do exactly what it was designed to do and execute the instruction. Even if you never authorized it.

That's the gap. And today, we closed it.

With the Governance Engine, @dfnsHQ becomes the first vendor to deliver a zero trust architecture end to end for institutions managing digital assets. Deployable on-premises, sovereign, and compliant by design.

The customer no longer needs to trust the operator of the platform. Not even DFNS itself.

What makes it different:
✔️ Environment-agnostic. It works whether or not you run enclaves.
✔️ Deployable on-prem or in a sovereign cloud, in the jurisdiction you choose.
✔️ It doesn't just prove what happened after the fact. It guarantees control before anything is signed.

If anything fails to verify, no signature is produced. The customer holds the veto. Absolute, deterministic, cryptographically enforced.

No one else offers that in the market today 🌐

It answers the question your CISO, your auditor, and your regulator are all about to ask in parallel:
𝘸𝘩𝘰 𝘥𝘰 𝘸𝘦 𝘩𝘢𝘷𝘦 𝘵𝘰 𝘵𝘳𝘶𝘴𝘵, 𝘢𝘯𝘥 𝘸𝘩𝘢𝘵 𝘩𝘢𝘱𝘱𝘦𝘯𝘴 𝘪𝘧 𝘵𝘩𝘦𝘺'𝘳𝘦 𝘸𝘳𝘰𝘯𝘨?

With the Governance Engine in your perimeter, the answer is: 𝗻𝗼 𝗼𝗻𝗲, 𝗮𝗻𝗱 𝗻𝗼𝘁𝗵𝗶𝗻𝗴 𝗯𝗿𝗲𝗮𝗸𝘀.
