Swiss digital asset bank Sygnum's B2B model is enabling a cryptocurrency boom in Switzerland by providing integrated infrastructure to traditional banks. Its partnership with Bancastato, a regional bank, allows clients to seamlessly trade cryptocurrencies like Bitcoin, Ethereum, Litecoin, and Solana directly within their existing bank apps. This eliminates the friction of using separate platforms. Under this model, Sygnum handles the backend trading infrastructure, custody, compliance, and regulatory licenses, while partner banks maintain their customer relationships and branding. This "infrastructure-as-a-service" approach allows banks to offer crypto services faster and more safely than building them in-house. Over 25 Swiss financial institutions, including Zuger Kantonalbank and PostFinance, now use Sygnum's B2B platform, making regulated digital asset services accessible to over a third of Switzerland's population. The trend reflects a shift where Swiss banks view crypto as another mainstream asset class rather than a niche product. Sygnum, a licensed bank itself with operations in Zurich, Singapore, and Abu Dhabi, leverages Switzerland's mature regulatory framework, which has integrated crypto into existing banking supervision. This environment, along with the concentration of blockchain firms in "Crypto Valley," is helping mainstream cryptocurrency adoption in the country, with an estimated 18-23% of Swiss residents already owning crypto assets.

A study by the Bank of Italy found that stablecoins do not offer a consistent advantage in cost or speed for cross-border money transfers. The research compared sending 200 USDC in 10 bilateral corridors (Italy to Brazil, Argentina, Japan, UAE, and South Africa) against standard money transfer services. While the final cost of stablecoin transfers ranged from 0.3% to nearly 9%, and were often cheaper than the global average cost of 6.65%, they only outperformed services like Wise in three out of seven comparable corridors. Key costs and delays were attributed to fees for converting to and from fiat currency and the quality of local payment infrastructure, not blockchain fees. Transfer times varied from under 20 minutes in corridors with instant payment systems to one or two business days where such infrastructure was lacking. The authors concluded that stablecoins' benefits would be more significant if they could be spent directly without conversion and noted that overly restrictive regulations complicate retail use without eliminating demand.

Regulated crypto bank Anchorage Digital has presented a strategy for preparing institutional assets for the post-quantum era, including implementing hybrid protection for internal TLS connections. The bank highlights that for cryptocurrencies, the main quantum risk lies in digital signatures, as Shor's algorithm could theoretically derive a private key from a public one. To mitigate this, Anchorage uses Bitcoin addresses based on a hash of the public key, which keeps the key hidden until a transaction is sent, and practices minimal address reuse. Internally, the company has deployed post-quantum key encapsulation for employee devices on ChromeOS and is implementing post-quantum cryptography within its hardware security modules (HSMs). A key proposal is the "Post-Quantum Turnstile" mechanism, which uses STARK zero-knowledge proofs to allow users to migrate signing rights to a post-quantum key without exposing their old private or public key. This could help secure an estimated two-thirds of circulating coins that might otherwise become inaccessible if the network phases out classical signatures. Furthermore, Anchorage open-sourced its Rust implementation of the SQIsign digital signature scheme, which it claims offers signatures about seven times smaller than the Falcon algorithm. This comes amid warnings that around 6 million BTC in addresses with exposed public keys could be vulnerable to future quantum attacks.

Italy's largest banking group, Intesa Sanpaolo, sharply reduced its stake in the iShares Bitcoin Trust (IBIT) while significantly increasing its position in the iShares Staked Ethereum Trust ETF (ETHB) during Q2. According to a 13F filing, the bank's holdings in IBIT plummeted by 93.7% to 40,723 shares as of June 30, from 646,809 shares at the end of March. The associated call option position was reduced by over 99%. Concurrently, its stake in the Ethereum-focused ETHB fund more than tripled, rising from 116,200 to 349,600 shares. The report also noted a dramatic reduction in its holdings of a Bitwise Solana Staking ETF. The BlackRock-managed ETHB fund, launched in February 2026, combines exposure to Ethereum's market price with staking rewards and held approximately $562.5 million in net assets by early August. Intesa Sanpaolo reported total assets of €992.67 billion and a net profit of €5.55 billion for the first half of 2026.

On August 3, 2026, Qatar's Dukhan Bank became the first Islamic (Sharia-compliant) bank in the country to join JP Morgan's blockchain-based deposit token network, Kinexys. This integration provides the bank's corporate and institutional clients with 24/7 cross-border settlement capabilities, removing time zone constraints for treasury operations. The move is part of Dukhan Bank's broader digital transformation. The bank stated that Kinexys enhances the speed, transparency, and efficiency of cross-border payments while aligning with Islamic finance principles. JP Morgan's platform converts client cash deposits into tokens for near-instant settlement within the regulated banking system and handled over $4 trillion in transactions by June 2026, supporting eight currencies. Kinexys, formerly known as Onyx, now counts eight major Gulf banks among its users. JP Morgan's JPM Coin, a regulated deposit token, is central to the network and is also available on Coinbase's Base network, with planned integration into the Canton Network. In November 2025, Kinexys partnered with Singapore's DBS Bank to develop interoperability for transferring tokenized deposits across different blockchain systems.
