Self-hosted MPC gives you a native cryptographic intercept point. You can configure screening webhooks directly in your own pipeline, blocking high-risk transactions at the node level before they ever execute. Read the full guide: dub.sh/aml-monitoring…

Regulators under MiCA, MAS PSN01, and APAC VASP frameworks now expect prevention over detection. Flagged addresses must be rejected before a transaction hits the chain. Where this check intercepts your pipeline depends entirely on your custody architecture.

The Travel Rule is now live in 85 jurisdictions, and FATF’s March 2026 data shows stablecoins make up 84% of flagged volume. Having a KYT tool is no longer enough. Regulators now require that screening happens before a transaction is signed. 🧵

Most teams think TRON custody is about protecting private keys. In reality, the bigger challenges often come from operations: → Energy management → Address architecture → Blacklist monitoring → Fee optimization As TRON now processes most global USDT transfers, custody becomes more than a wallet security problem, it becomes an infrastructure problem. We broke down what that means for exchanges, fintechs, payment providers, and stablecoin operators. Read more: fystack.io/blog/tron-usdt… #TRON #USDT #Stablecoins #CryptoInfrastructure

The Ethereum debate gets a lot clearer when you realize: Most businesses don't use Ethereum the way people think. They don't process every transaction on Ethereum L1. Instead: → Layer 2 handles transactions → Ethereum handles settlement Users get speed. Businesses get security, liquidity, and interoperability. That's why Ethereum is increasingly becoming a settlement layer, not just a blockchain.

Ethereum vs. Solana isn't really a TPS debate anymore. For businesses, the decision often comes down to: • Liquidity • Stablecoin adoption • Infrastructure maturity • Tokenization opportunities • Regulatory readiness Solana is optimized for execution. Ethereum increasingly acts as a settlement and asset layer. Different strengths. Different tradeoffs. We break it down for stablecoin payments, tokenization, and enterprise adoption 👇 fystack.io/blog/ethereum-…

@bytesbybree @alxs0x @LiskSEA Thank you a lot for supporting us through the program @bytesbybree

We’ve just wrapped up our journey in the Empower Residency Program at @UnchainedSummit 2026. Over the past week, @fystack team has also been presenting and connecting with builders across Web3 Builder Summit and Davas 2026. It’s been an incredible opportunity to represent founders from emerging markets who are building innovative solutions for the next generation of onchain applications. A special thank you to @sqrDAO, @Lisk, Leo, @alxs0x, @Cris7ran, @bytesbybree, @0xDankiii, @harrybui31, @TheVinhNguyen4 and all the mentors, partners, and friends who supported us throughout this journey. We’ve met amazing people, forged valuable partnerships, and gained insights that will help shape our next chapter. Now it's time to take @fystack to the next level: building the custody layer that enables fintechs in emerging markets to launch secure onchain applications.

We believe self-hosted #MPC is an option worth exploring. It ensures your signing authority stays physically inside each jurisdiction, keeping you compliant without relying on an external vendor's geographic roadmap. Read the full architectural breakdown: dub.sh/DataResidency

To close this vendor coverage gap, our latest guide breaks down three essential architectural patterns: > Compliance Data Separation > Isolated #Payment Rails > Distributed #MPC Key Shares

Mind these 6 words from Hong Kong's banking regulator, as they will change how your #fintech approaches cross-border custody: "localisation expectations in relation to private keys."

Fystack is joining @UnchainedSummit as an Exhibitor on 28–29 May at Furama Resort Danang, Vietnam. We’re building the custody layer for stablecoin infrastructure - enabling enterprise custody, stablecoin payments, and treasury operations with full control over assets and workflows. With one stack for every stablecoin rail, businesses can integrate across multiple blockchains without needing a dedicated Web3 team. #EventbyAeternum #UnchainedSummit #Fystack #Stablecoin #Custody #Treasury #Web3 #VietnamWeb3

3 markets. 3 regulatory frameworks. 3 different banking realities. Most operators pick one and figure out the rest later. That's usually where things break. Here's what compliance actually looks like across Central Asia, and what most teams miss before they launch: ↳ Kyrgyzstan: fastest licensing, hardest banking ↳ Kazakhstan: strongest institutional credibility (AIFC-first) ↳ Uzbekistan: strictest setup, but stablecoin-ready from Jan 2026 The full breakdown 👇

Central Asia is quietly becoming one of the most important stablecoin settlement corridors in the world. But Kyrgyzstan, Kazakhstan, and Uzbekistan are NOT the same market. Different regulators. Different banking risks. Different licensing paths. Different expectations around custody and compliance infrastructure. We broke down: → Which country is easiest to enter → Where institutional operators are actually building → Why banking due diligence is now harder than licensing → How Travel Rule fragmentation creates operational risk → Why self-hosted MPC custody is becoming critical for payment operators If you're building: • Stablecoin remittance infrastructure • Cross-border payment rails • OTC or treasury operations • Crypto settlement platforms in emerging markets This is a market you should understand before expanding. fystack.io/blog/crypto-co….

The threat today is "Harvest-Now-Decrypt-Later" attacks. Adversaries are capturing encrypted data right now to crack when quantum hardware matures. Start planning your migration today so you can upgrade on your own terms. Read the full breakdown: dub.sh/Quantum-Resist…

Quantum-resistant MPC fixes this gap. It keeps your node-sharing structure intact but swaps out ECDSA for NIST-standardized, lattice-based math. Your keys stay split, but the underlying cryptography shifts to data structures that quantum computers cannot solve.

Google just updated the math on quantum threats. Their latest research reveals that cracking the cryptography securing Bitcoin and Ethereum requires 20x fewer quantum resources than previously estimated. The timeline for crypto custody is shifting. 🧵
