AllUnity launched USDAU, a US dollar-backed stablecoin issued under the European Union's Markets in Crypto-Assets (MiCA) regulation, on September 30, 2026, deploying the token simultaneously across six blockchains. The issuer, a BaFin-licensed electronic money institution, made USDAU available at launch on Ethereum, Solana, Base, Tempo, Arc and Polygon, with additional networks expected later this year, according to a report by Crypto News.

The launch is the first concrete case study of a dollar e-money token operating under MiCA's full requirements, and it targets corporate treasuries rather than retail speculation. Only eligible institutional clients can mint and redeem USDAU 1:1 at par through AllUnity's Business Mint Account. Banking Circle provides transaction banking for the dollar reserves, and Flowdesk acts as liquidity provider.

Alongside the token, AllUnity introduced Instant FX, a feature that enables on-chain conversion between supported currencies. The design lets a business settle cross-border invoices or manage treasury positions without leaving the blockchain environment — a direct operational challenge to correspondent banking timelines and costs. A single issuer passport covers all 27 EU member states, which simplifies treasury architecture for companies operating across the bloc.

What MiCA requires

MiCA, which took full effect for stablecoin provisions in mid-2024, imposes five core obligations on issuers of asset-referenced tokens and e-money tokens, as set out by the European Securities and Markets Authority (ESMA). Issuers must hold a license as a credit institution or e-money institution — AllUnity satisfies this through its BaFin e-money license. They must maintain full reserve backing with no rehypothecation, invested in high-quality liquid assets and aligned with redemption demands at all times. Holders must be able to redeem at par at any time, with defined timelines and no fees. Issuer assets must be segregated from the issuer's own funds to protect users in insolvency. Finally, issuers must publish a white paper disclosing risks, redemption mechanics and governance.

For corporate users, the allocation of responsibility is now clearer. The issuer shoulders regulatory obligations around reserves and redemption; the user retains AML/KYC duties and transaction monitoring. That division addresses the concerns that have kept many treasury functions away from stablecoins: uncertainty over asset segregation, redemption guarantees and regulatory reprisal.

The US contrast

The US regulatory picture remains fragmented by comparison. The GENIUS Act — the Guiding and Establishing National Innovation for US Stablecoins Act — would create a federal framework for stablecoin issuers, but as of September 2026 it has not passed. US businesses must instead navigate state-by-state licensing, with New York's BitLicense and Wyoming's special-purpose depository institutions as prominent examples. The Citi-Coinbase partnership, reported earlier this year, has become a template for bank-grade stablecoin payments in the US, but it operates within existing state rules rather than a unified federal standard.

This dual-track reality shapes cross-border treasury design. Companies with US and EU operations may find it operationally simpler to use a MiCA-compliant stablecoin for European flows while maintaining separate state-level compliance for US activity. The GENIUS Act has bipartisan support in principle, but disagreements over state versus federal jurisdiction, consumer protection and reserve composition have stalled passage.

Operational implications

For treasuries evaluating integration, the practical path runs through AllUnity's institutional requirements. Corporate clients must pass KYC/KYB checks to open a Business Mint Account; DAOs and other on-chain organizations will likely need a legal wrapper such as a foundation or association to qualify. Once onboarded, a treasury can mint at par, acquire tokens through Flowdesk, and select among the six supported chains based on settlement speed, cost and DeFi integration needs — Ethereum for protocol connectivity, Solana for speed, Polygon for lower-cost payments.

The fiat on- and off-ramp remains the critical compliance chokepoint. Firms must ensure conversion venues are properly licensed in their jurisdiction and must maintain an audit trail linking each issuance or redemption to a verified corporate bank account.

AllUnity is not alone in the MiCA pipeline. Circle launched its euro- and dollar-pegged MiCA-compliant stablecoins earlier, and several other issuers are queued behind them. As more licensed issuers enter, competition is expected to focus on redemption speeds, FX integrations and multi-currency suites offering on-chain conversion between euros and dollars.

With the GENIUS Act still pending and AllUnity promising additional chain deployments before the end of 2026, the competitive window for MiCA-licensed dollar tokens is now open — and issuers that fail to match institutional minting, par redemption and built-in FX will find the EU's regulatory bar increasingly expensive to clear.
