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!

Less code. More control. You don’t need a blockchain team to build stablecoin infrastructure. Fystack handles the custody layer, so your team can focus on building your product, not the infrastructure underneath it. Build faster. Stay in control.

At $100M in monthly stablecoin volume, a 1.5% processing fee costs $1.5M a month. What if you owned the infrastructure instead of renting it? Our latest blog breaks down the cost crossover point, the trade-offs, and when payment processors should run their own stablecoin rails. The goal isn't to build everything yourself. It's knowing what to own, and when. Read the full breakdown below. fystack.io/blog/how-payment-…

Deposits land in different wallets. Your treasury shouldn't have to chase them. Fystack Auto Sweeping consolidates funds into a central vault when balances meet your configured rules. Set the rules once. Sweeps are policy-checked and MPC-signed, with no need to move funds manually every time. One less operational task to manage as your payment volume grows. See how it works. 👇

Stellar was built with a clear focus: making money move. That narrow focus now shows up in who is using it. MoneyGram launched its own stablecoin, #MGUSD, on Stellar in June. DTCC selected Stellar for tokenized securities. Look closer and every use case falls into three jobs: → Issue: stablecoins, tokenized funds, securities → Move: payments, cash-in and cash-out, remittances → Hold: lending pools, corporate treasury Before you build, understand the trade-offs. We break down 8 Stellar use cases, the controls behind them, and what builders should consider: fystack.io/blog/stellar-use-…

Your system shouldn’t have to keep asking what happened. A withdrawal was created. It was approved. It was executed. Your backend needs to know when each event happens. That’s what webhooks are for. Fystack sends event data directly to your endpoint as events happen, so your system can update records, trigger workflows, or notify your team without constantly polling the API. One event. One delivery. Your system takes it from there.

𝐖𝐚𝐥𝐥𝐞𝐭𝐬 𝐦𝐨𝐯𝐞 𝐚𝐥𝐥 𝐝𝐚𝐲. 𝐘𝐨𝐮 𝐬𝐡𝐨𝐮𝐥𝐝𝐧’𝐭 𝐡𝐚𝐯𝐞 𝐭𝐨 𝐰𝐚𝐭𝐜𝐡 𝐭𝐡𝐞𝐦. That’s why we built Alerts into Fystack. You can set an alert for things like a deposit, a withdrawal request, an approval, or an execution. You can also set a simple trigger, like when a wallet balance falls below a certain threshold. When it happens, 𝐅𝐲𝐬𝐭𝐚𝐜𝐤 𝐀𝐥𝐞𝐫𝐭𝐁𝐨𝐭 sends it straight to your Telegram group or channel. No need to keep checking the dashboard just to see if something happened. 𝐒𝐞𝐭 𝐢𝐭 𝐨𝐧𝐜𝐞. 𝐆𝐞𝐭 𝐧𝐨𝐭𝐢𝐟𝐢𝐞𝐝 𝐰𝐡𝐞𝐧 𝐢𝐭 𝐦𝐚𝐭𝐭𝐞𝐫𝐬.

Fystack v0.3 is live. We just shipped new tools for wallet operations, security, transaction management, and compliance. What this unlocks: → Manage addresses across multiple chains from one address book → Monitor sweep activity, catch repeated failures, and reset stuck tasks → See active devices, locations, and IPs, and revoke unrecognized sessions → Enforce MFA across your workspace → Track webhook requests and responses → Search transactions and export them as CSV → Screen incoming deposits for sanctioned addresses and AML risks with Webacy KYT One important change: Wallet-level auto-approval limits are now removed. Auto-approval is configured through policies, giving you more control over transaction approval rules. See the full changelog: fystack.io/changelog

Have you searched the EU crypto register for your on ramp provider and found no result? A missing entry can mean the authorisation is held by a separate legal entity registered under a different name.

For example, Ramp Network appears as Ramp Swaps (Ireland) Limited, while Banxa operates through EU Internet Ventures B.V. Identifying the legal entity helps establish which regulator granted the authorisation and which EU markets it covers.

You also need to think about: → Account reserves → Trustlines → Memos and deposit routing → Issuer controls → Transaction rules These details can affect how you build wallets, deposits, withdrawals and custody flows.

Getting a license is only one part of operating in the UAE/GCC. The harder part is staying compliant as your business, capital requirements, customers, and the rules change. Five things founders often overlook: • A free-zone license doesn’t automatically cover payment-token activity. • Minimum capital needs to be maintained continuously. • A license in one GCC market doesn’t automatically give you access to another. • AML screening may require more than checking OFAC. • Regulatory rulebooks can change, so compliance isn’t a one-time project. The goal isn’t to find the shortest path to a license. It’s to build a setup that still works after you get one.

Get a UAE crypto license” sounds simple. It isn’t. The UAE has multiple regulatory frameworks, and the one that applies to you depends on where your company is incorporated and what services you offer. • Dubai Mainland → Virtual Assets Regulatory Authority (VARA) • ADGM → Financial Services Regulatory Authority (FSRA) • DIFC → Dubai Financial Services Authority (DFSA) • Other UAE Mainland → Federal Securities and Commodities Authority (CMA) • AED / payment stablecoins → Central Bank of the UAE (CBUAE) And there’s one important catch: stablecoin businesses may need CBUAE approval in addition to their primary regulator. We put the basics into one map so you can quickly see where your business fits. Download the free ebook: link.fystack.io/compliance.m…
