Amundi Launches Tokenized Swap Fund on Ethereum and Stellar

Europe's largest asset manager, Amundi (€2.4 trillion AUM), has debuted its second on-chain product: the Spiko Amundi Overnight Swap Fund (SAFO), a tokenized UCITS vehicle with its shareholder register hosted on both Ethereum and Stellar. The fund is co-issued with tokenized fund platform Spiko and uses Chainlink oracles to publish net asset value data across both networks in real time.

SAFO is structurally distinct from the tokenized Treasury bill products that currently dominate the on-chain RWA market. Rather than holding government securities directly, it uses fully collateralized total return swaps — starting with BNP Paribas as counterparty — to deliver stable yields above risk-free benchmarks. Other eligible counterparties include Goldman Sachs, JPMorgan, Citi, Morgan Stanley, Barclays, UBS, Société Générale, Crédit Agricole CIB, and HSBC. The fund is available in EUR, USD, GBP, and CHF. CACEIS serves as depositary bank and administrator; Spiko acts as transfer agent, tokenization platform, and broker.

The dual-chain architecture pairs Ethereum's smart contract ecosystem with Stellar's lower-cost settlement rails — a design choice that prioritizes distribution reach alongside composability. This is Amundi's second blockchain-based fund issuance following a tokenized money market fund on Ethereum in November 2025. Spiko itself crossed $1 billion in distributed asset value in February.

🏦 COMPANY MOVES

• Centrifuge × LayerZero — The two firms announced a partnership to expand Centrifuge's institutional RWA tokenization infrastructure across more than 165 blockchain networks via LayerZero's OApp standard. The first products to adopt LayerZero include JTRSY (nearly $861M in tokenized U.S. Treasuries), JAAA, and SPXA — the first licensed tokenized S&P 500 index fund, launched in September 2025. Those three funds will expand distribution across Ethereum, Solana, Avalanche, BNB Chain, Base, Optimism, and HyperEVM. The deal also positions Centrifuge assets for eventual deployment on Zero, LayerZero's recently launched Layer 1 blockchain, which counts Citadel Securities, DTCC, Intercontinental Exchange, and Google Cloud among its backers. (The Defiant, March 19)
• EtherFi × Plume Network — Crypto neobank EtherFi (~$6B TVL) is integrating Plume Network's Nest Vault infrastructure to offer users access to tokenized RWA yield. The rollout centers on Plume's nBASIS vault, powered by Superstate's USCC fund, which targets returns from basis spreads across Bitcoin, Ether, Solana, and XRP. EtherFi will first reallocate capital to the vault, with a direct UI integration to follow. The move illustrates how DeFi-native platforms are layering institutional RWA exposure into consumer-facing products as on-chain DeFi yields compress. (The Defiant, March 19)
• Northern Trust Asset Management — Launched a tokenized money market share class, adding institutional weight to the growing field of on-chain fund wrappers. (via Finextra, March 2)
• Mastercard — Agreed a $1.8 billion acquisition of stablecoin platform BVNK, in a significant signal of payments-rail consolidation around programmable money infrastructure. (via Finextra, March 17)

⚖️ REGULATORY WATCH

SEC Issues Landmark Crypto Classification Guidance
The U.S. Securities and Exchange Commission published a sweeping interpretation of federal securities laws on March 17 that formally categorizes virtually all crypto assets into two buckets: tokenized securities and non-security crypto assets. SEC Chair Paul Atkins, speaking at the DC Blockchain Summit, declared that "the SEC's persistent failure to provide clarity on this question is over," and confirmed the Commission is implementing a token taxonomy framework. The guidance broadly designates Ether, Solana, and XRP as commodities — a classification the industry had sought for years. Importantly for RWA issuers, the distinction between tokenized securities and non-security assets creates a clearer compliance pathway for on-chain fixed-income and fund products. The House-passed Clarity Act, which legislates similar classifications, remains stalled in the Senate. (DL News, March 17)

Eurosystem Publishes Appia Roadmap
The ECB's Eurosystem published its Appia roadmap in March 2026, setting out a multi-phase plan to shape a European tokenized financial ecosystem using DLT for wholesale central bank money settlement. The roadmap outlines objectives for preserving the role of central bank money as an anchor of trust and financial stability as tokenized markets evolve, along with a public consultation process inviting stakeholder input on forthcoming analytical and practical work. The initiative — formerly known as the Exploratory Work — represents the Eurosystem's most concrete commitment to date to a DLT-native settlement layer for institutional European financial markets. (ECB Appia)

U.S. Senate Passes CBDC Ban
The U.S. Senate passed legislation prohibiting the issuance of a retail central bank digital currency. The vote, reported on March 13, reflects continued Congressional resistance to a Fed-issued digital dollar — a stance that implicitly keeps more space for tokenized bank deposits and stablecoins to fill the domestic digital payments gap.

🔍 WORTH WATCHING

Multichain distribution is becoming the new standard for institutional RWA issuance. The LayerZero–Centrifuge deal, Amundi's Ethereum+Stellar architecture for SAFO, and Centrifuge's upcoming expansion across seven chains all point to the same structural shift: single-chain fund issuance is increasingly seen as a distribution constraint. Issuers are now designing for reach from day one, treating interoperability protocols as part of the core product stack rather than a secondary add-on. The implications for custody, compliance, and settlement are still being worked out — but the direction of travel is clear. Separately, the Bank of Canada completed a DLT-based bond issuance experiment in early March (via Finextra, March 9), adding to a growing body of central bank evidence on on-chain sovereign debt. Watch for regulatory frameworks — particularly MAS and MiCA implementation guidance — to catch up to issuance practices in H2 2026.
