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!

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.

Really appreciate you digging past the headline, @shelleymaeph.
Your point about the gap between “a cool wallet” and infrastructure a regulated financial company can actually deploy really hit home for us at @fystack.
We’ve been on that journey ourselves, working with teams across fintech, crypto cards, payments, and digital assets. A hackathon demo is one thing. Turning it into infrastructure that a real business can rely on takes persistence, iteration, security, compliance, and a lot of learning from actual customers.
And we think that’s the part worth sharing more openly.
So beyond product updates, we’ll be sharing more about how we actually build and deploy custody infrastructure, including the technical decisions and lessons along the way.
Follow @fystack if you want to follow the journey. Would love to hear your thoughts as we share more.

MoonPay, Ramp, Transak and Onramper all call delivery time an estimate. None publishes an SLA.
NN/g found people shown a progress bar were willing to wait 3x longer.
Visibility does a lot of the work.

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

Stellar Vietnam builders shipping🇻🇳.
Fystack just hosted a live demo deploying a fully self-hosted, open-source MPC wallet on Stellar.
Congrats to @thicody and the Fystack team on the launch.
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!

Scaling a ramp means scaling every transaction underneath it.
So the question isn't only: How do we get more volume?
It's also: Which costs scale with volume, and which ones can we redesign?
We broke down the wallet, sweeping, and TRON economics here: dub.sh/crypto-on-ramp-fees
