👁️ Watch any wallet address on @dfnsHQ. In the dashboard, you can now register any onchain address, even one you don't control, and DFNS indexes it like your own wallets. Our CPO Chris Sutton shows how in about a minute: ✔️ The new "Watchlist" tab inside the "Wallet" page ✔️ Add a watch, pick a network, name an address, and sign with a passkey ✔️ Send funds to the address and the transaction appears as if it was your wallet Finance is about reacting to accounts you don't own. Until now, watching wallet addresses meant running your own indexing engine. With watchlists, you only need to create a registration and leave the rest to us. That's what onchain core banking is for. 🔘 Watch the demo: 📖 Read it: ⌨️ Start building today:

Idle stablecoins in a wallet earn nothing. Our CPO Chris Sutton puts it to work in about a minute. Allocations on @dfnsHQ now includes six new vaults powered by @yield_xyz, across Ethereum and Base. In the demo, Chris: 1️⃣ Opens Allocations and hits Create position 2️⃣ Selects a protocol (@gauntlet_xyz's USDC Prime vault, yielding ~4% a year) 3️⃣ Picks a wallet holding 10 USDC, deposits 5, signs with a passkey 4️⃣ Position created. The USDC starts earning immediately What makes this flow institutional-grade is what you don't see: ✔️ Every deposit and withdrawal passes the Policy Engine before final signing ✔️ Every payload is validated against the "Shield" library before execution ✔️ The position lives in your custody and audit log as every other movement Treasury teams have always had a choice between yield and control. DFNS' Allocations removes the choice. That's what onchain core banking is for. 🔘 Watch the demo: 📖 Read it: ⌨️ Start building today:

DFNS is part of @WalletConnect's new certified cohort. Session handling, blockchain support, metadata accuracy, error handling, all tested by @reown_ From now on, when a @dfnsHQ wallet connects to any app on WalletConnect, the request will carry a certified check mark ☑️ That’s over now. We’re adding: ✔️ WalletConnect Pay: one-click payments through a certified connector ✔️ Wallet Analytics: connections, active users, USD volume, top countries and peer benchmarking ✔️ Clear Signing: human-readable transactions we validate before signing.

Your SOC should have detection rules for every system that can move money. Starting today, @dfnsHQ can export its audit trail to your SIEM, starting with @datadoghq Cloud SIEM 🐕 Privileged action signed on DFNS, like moving funds, exporting a key, changing a user, a policy, or an access control, arrives in your security operations as a structured log the moment it resolves. It will show you: 𝗮𝗹𝗹𝗼𝘄𝗲𝗱, 𝗱𝗲𝗻𝗶𝗲𝗱, or 𝗳𝗮𝗶𝗹𝗲𝗱. This includes the attempts, such as a transfer signed and denied by policy. The type of signal that reveals stolen credentials or insider testing limits... What your SOC can now do with it: ⚠️ Alert on any key export, anywhere, instantly ⚠️ Flag policy changes outside the change window ⚠️ Catch a spike in denied actions from one user ⚠️ Surface a transfer at 3am from someone who's never operated at night ⚠️ Correlate a DFNS action with the same user's suspicious IdP login 20 minutes earlier 🛡️ We built SIEM Export like a security control. It never blocks the action it observes, but instead runs on an isolated channel so a SIEM outage can't touch your webhooks. Your API key is encrypted and never logged. When your analysts see something, DFNS can: → suspend an Org → revoke a User → tighten a Policy → deny a Wallet Your SIEM also holds an independent copy of the record, in your domain. Even if DFNS itself were ever compromised, your SOC keeps the history. That's what onchain core banking is for. 📖 Read the announcement: ⌨️ Start building today:

🔐 He introduced phishing-resistant hardware MFA at Consensys in 2015. That was years before it was standard. And that's who runs corporate security now at @dfnsHQ. Welcome Eric Amlie, our new Tech Ops Manager on the security team. A decade of building identity and access infrastructure at fast-growing companies: → First IT hire at Paper, scaled the function from scratch to five engineers → Migrated 160 users and 50 apps to Okta Identity Engine in one week and zero downtime → Ran IAM for global teams at ConsenSys during Ethereum's formative years → Four SOC 2 drives at four companies We tell our clients that access is not permission and that offboarding should be one action, immediately complete.

🔒 10 USDC in a vault. Lock 5. The total balance still reads 10, but only 5 can move. That's the new Lock feature within Vaults, and our CPO Chris Sutton demos it in 90 seconds. Vaults give you a balance sheet while Locks make reservations real. In this demo: 1️⃣ Chris opens a vault holding 10 USDC on Ethereum 2️⃣ He picks the asset, locks 5 USDC, reviews and signs with a passkey 3️⃣ The vault now shows 5 available and 5 locked. Nothing moved onchain. 4️⃣ He tries to think about transferring the locked 5 but DFNS won't allow it. 5️⃣ Unlocking requires a click and a passkey signature from the right user. Three reasons you'd want this: → Escrow where funds must be proven present before delivery. → Settlement where a venue needs certainty you can settle without pre-funding. → Or holding a portion of a balance for additional review before it goes anywhere. The funds never move. Custody never changes hands. What changes is what the balance can do. That's what onchain core banking is for. 🔘 Watch the demo: 📖 Read it: ⌨️ Start building today:

Proving a commitment in digital assets has always meant handing them over 😨 Capital would usually leave your control to prove a point and it would sit under someone else's risk until the point no longer needs proving. Today, we're releasing 𝗟𝗼𝗰𝗸𝘀 so you can commit funds to a counterparty 𝘸𝘪𝘵𝘩𝘰𝘶𝘵 𝘮𝘰𝘷𝘪𝘯𝘨 𝘵𝘩𝘦𝘮. A lock is a reservation inside your vault. Nothing moves onchain. Your counterparty gets an enforceable guarantee, you keep custody, and only the net result ever settles. We built the feature so neither side takes the other's word for anything: 🔒 Nothing locks without you. Every lock clears your approval quorum, enforced below the API. 🔓 Nothing unlocks without them. Only the lock owner can release, reduce, or settle against it. 🔙 Nothing unwinds it from the side. While a lock is active, the owning account can't be edited. Three use cases, one primitive: ✔️ Settlement: trade all day against 5 BTC locked at home. Sold 2? One transfer settles, 3 release back. ✔️ Collateral: the lender locks collateral in your vault. It can't be spent by you, can't be rehypothecated by them. A margin call is a lock increase, with your approval. Repayment is a release. ✔️ Escrow: funds locked until delivery. No third-party custody, no wire out and back. For a treasury, it's the difference between capital that works and capital that waits. That's what onchain core banking is for. 📖 Read it: ⌨️ Start building today:

🤝 @dfnsHQ and @OwneraIO have signed a strategic partnership. Together, we’re bringing tokenized collateral mobility and intraday financing to production. Ownera is behind FinP2P, an open protocol for connecting tokenized markets. Institutions connect once and can transact across EVMs, @CantonNetwork, @inside_r3, @hedera, @solana and legacy systems, atomically. → $5B in orchestrated volume per month → Backed by @jpmorgan and @usbank → Intraday repo already in prod validated with 70+ institutions Collateral is where tokenization gets real. Margin calls happen across time zones and outside settlement windows. Cash sits in one system, securities in another, and the systems managing margin often cannot talk to each other. Tokenization solves the timing. Interoperability solves the fragmentation. But institutions still need to control what can move, who can approve it, what it is locked against, and how every action is recorded. That’s where DFNS comes in: ✔️ Policies that control and approve every collateral movement ✔️ Vaults tied to the balance sheet and operation behind them ✔️ Locks that reserve collateral against an obligation ✔️ Full transaction lifecycle and audit trail Ownera and DFNS connect the network between institutions with the controls inside them. 📖 Read the announcement: ⌨️ Start building today:

Every fee on @arc is priced in dollars 💲 BlackRock, DTCC, Visa, and Mastercard run the validators. And it's on @dfnsHQ from day one. @circle's mainnet blockchain went live today, and DFNS supports it as a full Tier-1 network from launch. Arc is what a blockchain looks like when it's built for stablecoin finance instead of adapted to it: ✔️ USDC as native gas. Fees denominated in dollars, so treasury never holds a volatile gas token ✔️ Deterministic finality in under half a second, with no reorganization risk once a block is final ✔️ Full EVM compatibility, so existing contracts and tooling deploy unchanged ✔️ A founding validator set of @BlackRock @The_DTCC @galaxyhq @GlobalPayInc @ICE_Markets @Mastercard @MoneyGram @StanChart @Visa Sumitomo and SBI. For institutions on DFNS, this completes the Circle stack on one platform. 1️⃣ Mint USDC from a Circle treasury through Circle Mint. 2️⃣ Move it across chains through CCTP. 3️⃣ Settle payments and tokenized assets on Arc. Redeem to fiat. Every step through the same Policy Engine, in the same audit trail. Wallets, native and token transfers, smart contract execution with your own ABI, signing with no single point of failure, balances, webhooks. The full Tier-1 set, live today 🟢 That's what onchain core banking is for. 📖 Read it: ⌨️ Start building today:

We're bringing together the institutional leaders actually moving capital markets onchain, not just talking about it. See you at @Sibos Miami on September 30. @OpenZeppelin @dfnsHQ

🇦🇪 The Abu Dhabi Securities Exchange @ADX_AE has chosen @dfnsHQ. DFNS will deploy digital asset wallet and tokenization capability across its market infrastructure. ADX is the machinery of UAE’s capital markets: the exchange, AD Depository, and AD Clear. It’s the 2nd largest exchange in the Arab region by market cap, already listing digital bonds and tokenized stock. With this agreement, ADX becomes the first regional financial market infrastructure to embed wallet and tokenization capability into its core. ✔️ Issuance and servicing of tokenized instruments across their full lifecycle ✔️ Wallets for a market of issuers, members, custodians, and investors ✔️ Controls enforced before anything signs with an audit log regulators expect ✔️ Sovereignty over deployment with jurisdictional control over key material "𝘛𝘰𝘬𝘦𝘯𝘪𝘻𝘢𝘵𝘪𝘰𝘯 𝘪𝘴 𝘣𝘦𝘤𝘰𝘮𝘪𝘯𝘨 𝘢𝘯 𝘪𝘯𝘤𝘳𝘦𝘢𝘴𝘪𝘯𝘨𝘭𝘺 𝘴𝘪𝘨𝘯𝘪𝘧𝘪𝘤𝘢𝘯𝘵 𝘧𝘰𝘳𝘤𝘦 𝘪𝘯 𝘵𝘩𝘦 𝘦𝘷𝘰𝘭𝘶𝘵𝘪𝘰𝘯 𝘰𝘧 𝘨𝘭𝘰𝘣𝘢𝘭 𝘤𝘢𝘱𝘪𝘵𝘢𝘭 𝘮𝘢𝘳𝘬𝘦𝘵𝘴," said Abdulla Al Nuaimi, CEO of the ADX Group. The ambition is to position Abu Dhabi as a global hub for the next generation of capital markets. The first wave proved a bond could exist onchain. The next wave makes the whole market run there. That work has begun in Abu Dhabi. That's what onchain core banking is for. Welcome to DFNS, ADX. 🤝 📖 Read the announcement: ⌨️ Start building today:

Abu Dhabi Securities Exchange (ADX) Group and DFNS have entered into a strategic agreement to provide digital asset wallet and tokenization capabilities for on-chain assets.

📑 New series: One deep dive per cloud DFNS supports. First up: 𝗔𝗪𝗦. We are starting with Amazon Web Services (AWS) because that’s where we started. @dfnsHQ has been an @awscloud customer since day one, 6 years ago. The post covers everything we do with AWS. At its center, the question most vendors answer for you: 𝘸𝘩𝘦𝘳𝘦 𝘴𝘩𝘰𝘶𝘭𝘥 𝘵𝘩𝘦 𝘱𝘳𝘪𝘷𝘢𝘵𝘦 𝘬𝘦𝘺 𝘭𝘪𝘷𝘦? ✔️ TEE. Keys isolated inside AWS Nitro Enclaves, the model made famous by enclave-native platforms. ✔️ MPC. The default. Keys exist only as threshold shares, never assembled anywhere. ✔️ HSM. Keys in your own AWS CloudHSM cluster. FIPS 140-3 hardware, your account, your region, ✔️ Or use the hybrid: MPC shares sealed in Nitro Enclaves from your account. Nothing signs without you. And procure it all through AWS Marketplace, on the bill you already have. 500+ institutions. $200B+ secured. 99.997% uptime since 2022. Zero breaches since 2020.

📹 Watch 20 USDC land in a vault and get quarantined on arrival. Not flagged. Not reviewed. Held, by default, until someone with authority says otherwise ☑️ That's the point of Vaults, and our CPO Chris Sutton walks through the whole thing in under four minutes. Vaults sit alongside Wallets on @dfnsHQ. They are programmatic containers that give your wallets a balance sheet instead of a balance. In the demo, Chris: 1️⃣ Creates a vault with a name, an external reference, and tags, signed with a passkey 2️⃣ Adds networks, one address per network: Ethereum, Bitcoin, and Base, in seconds each 3️⃣ Sends USDC in from a faucet, and watches it arrive as a quarantined balance Every vault carries three balances: 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗹𝗲, 𝗾𝘂𝗮𝗿𝗮𝗻𝘁𝗶𝗻𝗲𝗱, and 𝗹𝗼𝗰𝗸𝗲𝗱. Incoming funds start in quarantine. The operator runs KYT and checks them against compliance rules before approving the release with a passkey. The funds then become spendable. Your existing wallet policies still apply. Dedicated vault policies let you automatically release funds when KYT passes. Hold first. Release when ready. That’s what a regulated business needs, not a raw wallet. That's what onchain core banking is for. 🔘 Watch the demo: 📖 Read the announcement: ⌨️ Start building today:

👁️ You can now watch any address on DFNS. Today, we released 𝗔𝗱𝗱𝗿𝗲𝘀𝘀 𝗪𝗮𝘁𝗰𝗵𝗲𝘀. Register any onchain address, DFNS treats it like your wallet. The industry usually calls this a “read-only wallet.” But those usually hide a key somewhere. Whereas an Address Watch on DFNS has none. No private key, no public key, no view key. Finance on shared ledgers means reacting to accounts you don't own. → A network operator's contract records a settlement. → A counterparty's address receives what you're owed. → A market infrastructure emits the event your back office is waiting for. So far that meant running your own indexing, polling nodes, and decoding logs for every network. Now it's one registration and the webhook you already use ✅ What you get: ✔️ Every value transfer touching the address from the moment the watch starts ✔️ Balances across the address's assets ✔️ Decoded smart contract events, event name plus fields, as structured data ✔️ Three additive webhooks with addressWatchId instead of walletId And the part your security team will like the most is that the transfer, signing, and export endpoints don't exist for Address Watches. Nothing on the platform can sign for an address it holds no key for. 🟢 Live on Ethereum, its testnets, and Besu-based private EVMs. 📖 Read it: ⌨️ Start building today:
