In Part 1, we explored what quantum computing really means for crypto security—and why preparation can’t wait. Now let’s take a closer look at how blockchains like Bitcoin and Ethereum are exposed, and how they’re beginning to adapt.

With the enactment of the GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins of 2025), the federal government has, for the first time, created a comprehensive legal and regulatory framework governing the issuance and operation of payment stablecoins. GENIUS introduces a national regulatory floor for licensing stablecoin issuers and sets standards for both domestic and foreign participants.

High-performance blockchains are quickly becoming critical infrastructure for institutions and fintechs building the next generation of payment rails, DeFi, and low-latency applications. As demand grows for faster and more scalable environments (with full EVM compatibility), new entrants are building innovative solutions tailored to institutional needs. This is what Monad aims to deliver: a next-gen blockchain designed for high throughput, low latency, and seamless developer experience.

Fireblocks has officially launched support for the Sui, the blockchain built for mass adoption, enabling institutional clients to securely custody SUI assets and access the growing range of applications built on the network via WalletConnect. Sui joins the expanding list of blockchains supported by Fireblocks, reinforcing our commitment to bring our customers the ability to participate in the industry’s most exciting protocols.

Last week, Binance began enforcing jurisdiction-specific regulations requiring Personally Identifiable Information (PII) for certain crypto withdrawals and deposits (Binance US is not affected). These updates carry immediate operational and compliance implications for Fireblocks customers based in Japan, New Zealand, India, the UAE, Bahrain, South Africa, Poland, France, and Kazakhstan who transact with Binance.

When I joined Fireblocks ten months ago, stablecoins were just starting to break into the payments conversation. Today, that conversation is everywhere. At Stablecon 2025 and in one-on-one conversations with PSPs, global marketplaces, and fintech leaders, I’ve seen the shift firsthand: stablecoins have crossed the chasm. In 2024 alone, Fireblocks infrastructure facilitated over $1.5 trillion in stablecoin transaction volume.

Banks and Financial Market Infrastructures (FMIs) have approached blockchain technology with both excitement and caution in recent years. They have been discouraged by regulators from engaging with permissionless blockchains. Many financial institutions have spent large amounts of time and money developing digital asset capabilities on highly permissioned and proprietary alternatives.

June sustained the stablecoin momentum, especially in the U.S., where legislation is at the final stretch. Around the world, regulators continued refining crypto intermediary and tokenization frameworks.

Minna Bank (“Minna no Ginko”), Japan’s first digital-native bank and a subsidiary of Fukuoka Financial Group, has announced a landmark initiative to explore how stablecoins and Web3 wallets can transform everyday financial services. In collaboration with Fireblocks, Solana, and TIS, the study will assess the technical and practical applications of stablecoins for real-world payments, trading, and next-generation user experiences.
