Fystack

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!

We’re proud to share that Fystack is now ISO/IEC 27001:2022 certified, the international standard for information security management. An independent auditor reviewed how we protect our systems and our customers’ data. Security is built into every layer: - Applications: secure development practices, code review and continuous testing. - Dependencies: we monitor third-party libraries and patch known vulnerabilities quickly. - Cloud and containers: hardened infrastructure, least-privilege access, and isolated workloads. - Internal access: our team works on a zero-trust network and signs in with hardware security keys. Private keys are never held in one place, thanks to our MPC wallet design. Our MPC engine is open source: github.com/fystack/mpcium Security isn’t a one-time milestone. It’s a commitment we renew every day. See all our security controls on our Trust Center: trust.fystack.io Thank you to our team and partners for helping us get here!

Most crypto losses at companies don’t need a hacker. They need one person with too much access. Fystack fixes that with workspaces: - each team gets its own wallets and API keys, - each person gets a role, - and withdrawals need 2 of 3 signers before they go out. Under it is the signing engine we open-sourced. Keys are split across nodes, so the full private key is never in one place. Read the code: github.com/fystack/mpcium

A secure wallet is not enough to protect customer funds. Crypto exchanges and OTC desks need to secure every step, from deposit detection and transaction signing to approvals, treasury operations, and reconciliation. But each has different operational risks. Explore the 6 layers of digital asset infrastructure and the controls that matter for each. Read the full guide: fystack.io/blog/digital-asse…

Fystack now runs on @Helius, with sponsored credits from @SuperteamVN. Faster Solana underneath. Same self-hosted control on top. Huge thanks @superteam, @SuperteamVN and @Helius.

Most stablecoin treasury platforms are built for US and European markets. But APAC has different needs. From local regulations to deployment requirements, fintechs need to evaluate more than just features. We compared 10 stablecoin treasury platforms for APAC fintechs and payment providers, including their strengths, limitations, and pricing. Read the full comparison: fystack.io/blog/best-stablec…

You don't need to rebuild your payment stack to settle in stablecoins. You need to know which parts to keep, which layers to add, and which operations to automate. Your processor and authorization engine can stay. The new work sits underneath them: wallet infrastructure, signing policies, blockchain connectivity, reconciliation, and treasury automation. The goal is simple: move settlement on-chain without disrupting the payment experience. Here's how to approach the architecture. Read the guide: fystack.io/blog/from-card-pa…

Proud to be one of 16 teams from Vietnam featured in this month’s Stellar Instawards 🇻🇳 Thanks @StellarVN! Every team building on Stellar needs to protect its private keys. But not every team should have to build the security infrastructure from scratch. That’s why we’re building an open-source MPC wallet for Stellar, allowing teams to manage key shares across multiple nodes without exposing the full private key in one place. Curious? Explore the code 👇 Demo: stellar-wallet.fystack.io/ GitHub: github.com/fystack/stellar-w…

Paying too much to send USDT on TRON? 👀 Fystack Gas Station integrates with TronZap to rent Energy when needed, helping eligible transactions cut network costs by up to 60%. Less TRX burned on fees. More efficient operations. docs.fystack.io/product/gas-…

Some good news from Fystack! We’ve received our 2nd Instaward from @StellarOrg. Building a fintech product on Stellar? Fystack lets you run MPC wallets on your own infrastructure, set approval policies, and give users an easier way to sign in with social accounts or passkeys. With MPC, the private key is split into shares across separate servers, so the full key never exists in one place. - Try the demo: stellar-wallet.fystack.io/ - Open source: github.com/fystack/stellar-w… Big thanks to @VN_Stellar and @riseinweb3 for the support!

One stolen credential shouldn’t be enough to access your account. Fystack supports 2FA and passkeys to help protect against unauthorized access and make phishing harder. An extra layer of security, without making everyday access more complicated. Secure your treasury with Fystack: fystack.io/

Every transfer needs gas. Managing it shouldn’t be a full-time job. Fystack Gas Tank lets you fund gas across multiple chains from one place. Track balances, automate refills, and keep transactions moving without manually topping up every wallet. One Gas Tank. Multiple chains. Less operational overhead. Gas, handled.
