The hidden cost of launching a crypto ramp in a new market? Liquidity. Every new market can add another local payment rail, another licensing setup, and another pool of fiat capital that needs to be funded before volume arrives.

New ebook: Virtual Asset Licensing Across the Middle East. VARA, ADGM, DIFC, Federal CMA, and CBUAE each have their own licensing process. They also have different capital requirements and timelines. If you're building custody, exchange, or stablecoin infrastructure in this region, you need to understand these requirements. The guide breaks down all five frameworks, plus Bahrain's CBB as an alternative entry point. It also covers five compliance risks that can catch even well-funded teams off guard.

Going on-chain changes what “card security” means. Your card program may already have authorization, processing, and settlement figured out. But once on-chain liquidity enters the stack, there’s a new question: Who can move the money? A settlement wallet has to stay online, move funds frequently, and connect to multiple systems. So securing it isn’t just about protecting the private key. It’s also about: → Who can initiate a transaction? → How much can they move? → What happens when an authorized system is compromised? We looked at real incidents across crypto payment infrastructure, from Alphapo and CoinsPaid to Multichain and 3Commas, and broke down the security lessons for teams running on-chain card programs.

How can OTC desks increase settlement capacity without increasing operational risk at the same rate? That becomes harder as trade volumes grow. More trades mean more approvals, more wallet operations, more settlement instructions, and more room for operational gaps between trade confirmation and final settlement. We put together a breakdown of the crypto OTC settlement process, looking at how institutional desks can manage this gap through pre-funding, controlled settlement, quorum approval, policy enforcement, and secure custody infrastructure.

Building digital asset custody infrastructure in-house can mean months of engineering, ongoing maintenance, and security work. Fystack provides compliance-ready custody infrastructure for financial companies building stablecoin and digital asset products. Teams can run Fystack on their own cloud or on-prem, keeping control of their keys, data, and compliance while managing wallets, stablecoin payments, treasury, and transaction policies through one API fystack.io/

MPC custody, built for @StellarOrg We just deployed a fully self-hosted, open-source MPC wallet on Stellar, built on Mpcium, our open-source MPC engine. Keys are split across independent nodes and never exist in one place. A transaction only goes through when enough nodes agree, using threshold signing to remove the single point of failure. In this demo, we spin up the MPC nodes with Docker, generate a Stellar keypair, and walk through deposit, withdrawal, signing, and swap. Built for fintechs, exchanges, and developers who want full control over their keys and infrastructure. Thanks to @VN_Stellar team for the support!

TRON adds another lever. For USDT flows, operators can burn TRX for Energy or rent it instead. Same transaction, very different economics.

More volume doesn't automatically mean better ramp margins. In the standard deposit address model, every new customer can mean two on-chain transactions before funds reach treasury. At 50 deposits/day, that's roughly 270M gas/month. And that's just one cost line.

Your users want to top up with USDT on TRON. But your card stack only supports Ethereum. So what happens when you add TRON? It’s not just another integration. Your backend now needs to handle a different transaction model, fee system, signing method, blockchain connectivity, and reconciliation flow. Then the same problem comes back when you add Solana. This is where multi-chain crypto card infrastructure gets complicated, and where the architecture you choose starts to matter. In our latest article, we break down how card providers can add new blockchain rails without rebuilding the card stack every time. Read the full article: fystack.io/blog/how-to-add-s….

What actually determines whether a crypto card program is profitable? Not interchange alone. Revenue has to survive processing, BIN sponsorship, FX, fraud, chargebacks, wallet infrastructure, node costs, and more. The metric that matters: Contribution margin per active card. If it's negative, more users just scale the loss. Our latest deep dive breaks down crypto card unit economics, break-even TPV, and when BaaS, hybrid, or in-house infrastructure makes economic sense.

Different rails. Same missing layer. JPMorgan chose Base. Citi runs its own ledger. 21 banks just agreed on a shared stablecoin. But settlement is only one layer. The real challenge is the infrastructure underneath: custody, policy enforcement, approvals, and operational control. Settlement tells money where to go. Infrastructure decides if it can move. We break down why this layer matters in our latest blog. 👇 fystack.io/blog/tokenized-ba…

JPMorgan, HSBC, Citi. Same word in every headline: "on-chain." Look closer and no two of these seven banks are building the same thing. 𝗙𝗼𝘂𝗿 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗯𝗲𝘁𝘀 ↳ Deposit tokens on a public blockchain. JPMorgan's JPMD has been live for institutional clients on Coinbase's Base since November 2025, and is now expanding to the Canton Network. ↳ A licensed, regulated stablecoin. HSBC and Standard Chartered hold two of Hong Kong's only stablecoin licenses. Standard Chartered's HKDAP just opened a limited institutional beta. HSBC's own HKD stablecoin is still coming later this year. Societe Generale has run this playbook the longest, its EUR and USD CoinVertible tokens have been live since 2023 and 2025. ↳ Tokenized deposits for corporate treasury. HSBC's Tokenised Deposit Service now runs across six markets. Citi Token Services runs across five. ↳ A shared network instead of a solo product. Bank of America is putting its weight behind The Clearing House's joint Tokenized Deposit Network, targeting first half of 2027, while its CEO keeps warning that trillions in deposits are at risk from stablecoins. Which model do you think will win at scale: deposit tokens, regulated stablecoins, tokenized deposits, or shared networks?

A look back at Hack Seasons Conference Ho Chi Minh City. The digital asset space is expanding beyond the blockchain-native world. It’s no longer just blockchain-native builders - teams from fintech, financial services, and infrastructure are joining in, each with a different view of where the market is heading. We saw this firsthand at the @fystack x @securosys booth, with conversations ranging from teams exploring digital assets for the first time to businesses already looking at how to integrate them into their existing operations. Thank you @thesensedotsol team for the amazing video!

Last week, @fystack joined Hack Seasons Conference Ho Chi Minh City as a sponsor, alongside @securosys, @Ledger, @SonicLabs, @birdeye_so , @Mercuryo_io and others. What stood out throughout the day was how naturally conversations moved between traditional finance and digital assets. We had the chance to speak with banks, payment companies and exchanges about where the industry is heading, from stablecoins and institutional adoption to custody, compliance and security. One thing was clear: the conversation is becoming much more practical. It's no longer just about whether institutions are interested in digital assets, but how they can actually operate them securely and compliantly. Thanks to @mpost_io team for the support throughout the event!

How can banks move digital money across multiple settlement rails without multiplying operational complexity? Project Agorá, Partior, mBridge, Ensemble and Project Guardian are approaching the problem from different angles. But for banks, the next challenge goes beyond settlement. They need to securely custody, approve, route and monitor digital assets across networks, while keeping treasury and policy controls intact. In our latest article, we break down the emerging settlement landscape and what it means for the infrastructure banks need to operate digital money at scale.

Fystack has partnered with @securosys to bring HSM-backed deployments to our custody platform for banks and institutional clients. While MPC remains our default architecture, institutions can now choose between MPC and HSM based on their security, compliance, and operational requirements - all through the same orchestration layer for wallet management, policy controls, approvals, and audit trails. Together, we're delivering more flexible, institutional-grade digital asset custody. #DigitalAssetCustody #MPC #HSM

Unlike the US or Europe, Singapore doesn't need crypto cards to replace banks. Its payment infrastructure already works. So why are crypto cards still growing? Because in Singapore, they're becoming an income and treasury tool, not just a payment tool. In our latest research, we compared the leading crypto cards available in Singapore by: • FX fees • Cashback (advertised vs. realized) • MAS licensing • Custody model • Tax treatment • Best card for different user profiles One takeaway stood out: For many Singapore users, FX fees matter more than cashback. Frequent travel across Southeast Asia can easily save more than chasing reward rates tied to volatile tokens.

Will your competitive advantage still exist in five years? Launching a stablecoin is getting easier. Building merchant distribution, payment orchestration, network effects, and switching costs isn't. That's why Stripe's reported bid for PayPal isn't just another M&A story. It's a reminder that the next phase of competition won't be about who issues another stablecoin. It'll be about who owns the layers between the infrastructure and the customer. In this article, we break down the four layers of the modern stablecoin payment stack and explain why they matter for banks, fintechs, payment providers, and infrastructure teams planning their long-term strategy.

A blockchain outage doesn't always mean lost funds. But it can still become an operational nightmare. For exchanges handling USDC on Base, there are two risks to prepare for: - A sequencer halt stops transactions for everyone, while funds stay safe. - A USDC freeze locks one specific address, while the chain keeps running. Neither MPC nor self-hosted custody removes these risks. The real question is different for each one. A sequencer halt hits every user at the same time, regardless of architecture. A freeze does not have to. ↳ With a shared hot wallet, one frozen address can lock funds for thousands of users. ↳ With dedicated, isolated addresses, a freeze stays contained to one customer relationship. Custody is not only about protecting keys. It's about designing infrastructure that limits how far one failure spreads, where that's actually possible.

Many fintechs see compliance as something to add later. That decision becomes more expensive as the business grows. Every new regulation can mean another integration, another vendor, and another layer of operational complexity. The teams that scale successfully don't treat compliance as an add-on. They build it into their infrastructure from day one. As APAC regulations continue to evolve, that approach is becoming less of a competitive advantage and more of a business requirement.

Most crypto firms entering SEA spend months studying regulations. The bigger risk is choosing the wrong custody infrastructure. A market that looks "easier" on paper can be harder to launch in practice. Indonesia's custodian bottleneck, Vietnam's data residency requirements, and the Philippines' closed licensing environment are all infrastructure problems before they're compliance problems. In SEA, your custody architecture may determine market access long before your legal team files paperwork.

Your treasury balance may be accurate. But it may never have existed at any single point in time. As stablecoin operations expand across TRON, Ethereum, and Solana, treasury teams often aggregate balances with different timestamps, confirmation models, and settlement assumptions into a single number.
