Germany-based stablecoin issuer AllUnity has launched a U.S. dollar-backed stablecoin across six blockchain networks while adding an instant foreign-exchange service aimed at businesses moving money between currencies.
USDAU became available on September 30 on Ethereum, Solana, Base, Tempo, Arc and Polygon. The token is structured as an e-money token under the European Union’s Markets in Crypto-Assets Regulation, or MiCA, and is issued by AllUnity, a BaFin-licensed e-money institution.
Each USDAU is designed to be redeemable for one U.S. dollar at par and is backed by segregated U.S. dollar reserves. AllUnity said fully onboarded institutional customers can mint and redeem USDAU without charge through its Business Mint Account.
The launch adds a dollar product to AllUnity’s existing stablecoin lineup, which already includes euro-backed EURAU, Swiss franc-backed CHFAU and Swedish krona-backed SEKAU. AllUnity was established by DWS, Flow Traders and Galaxy.
The dollar token arrives with several institutional partners already attached. Banking Circle will provide reserve and transaction banking services, while Flowdesk has been designated as USDAU’s liquidity provider. Archax will provide institutional minting and redemption access, and Hercle will support off-ramping and foreign exchange. Bitcoin Suisse, RULEMATCH, BitGo and Galaxy were also named as launch partners.
USDAU Launches on Six Networks From Day One
Launching simultaneously across six blockchains gives USDAU a broader initial distribution footprint than a stablecoin beginning on a single network and adding integrations later.
Ethereum remains a major institutional and decentralized-finance settlement environment, while Solana and Base have developed large consumer, trading and payments ecosystems. Polygon provides another established route into payments and financial applications, while Tempo and Arc are newer networks being developed around institutional finance and digital money use cases.
AllUnity said additional blockchain support is planned later in 2026.
The structure is also significant from a regulatory perspective. Under MiCA rules for e-money tokens, issuers must be authorized as either credit institutions or e-money institutions. Holders also receive statutory redemption rights, including redemption at par value.
That places USDAU within a growing group of stablecoins being built around regulated payment and settlement use cases rather than relying primarily on crypto-exchange demand.
A similar shift is visible elsewhere in digital finance. Dave Finances previously examined how Telcoin connected regulated bank accounts directly to an on-chain dollar, another attempt to move stablecoins deeper into everyday financial infrastructure.
Instant FX May Be More Important Than the Stablecoin Itself
The more interesting part of AllUnity’s announcement may be the product launched alongside USDAU.
AllUnity has added Instant FX to its Business Mint Account, allowing businesses to enter the platform using supported fiat currencies, mint stablecoins and move value between supported currencies within the same infrastructure.
The idea is relatively simple. A company operating internationally normally needs banking relationships, liquidity providers and payment infrastructure for multiple currency corridors. Moving euros into dollars, Swiss francs into euros or other combinations can involve separate accounts, cutoff times and intermediaries.
AllUnity is trying to compress some of that process into a stablecoin layer.
Instead of engineering a separate payment flow for every corridor, a business can potentially use the same account and stablecoin infrastructure to access multiple currencies, convert between them and settle value on-chain.
That is where the launch begins to look less like another dollar token and more like a foreign-exchange and treasury product.
Other companies are moving in the same direction. In Hong Kong, HashKey and OneInfinity have been exploring regulated stablecoins for insurance and cross-border payments, including settlement flows connecting Hong Kong with international markets.
Stablecoins Are Starting to Compete on Infrastructure
The stablecoin market already has plenty of dollar tokens. That means issuing another one is not, by itself, a strong competitive advantage.
USDT and USDC have enormous existing liquidity, exchange distribution and network effects. PayPal has PYUSD, Ripple is expanding RLUSD, and Paxos operates several regulated dollar products. Banks and payment companies are also developing tokenized deposits and other forms of programmable money.
For newer issuers, the competitive question is increasingly becoming what sits around the token.
Can businesses mint it easily? Can they redeem it directly into bank money? Is there deep liquidity? Does it work on the chains companies actually use? Can treasurers move from one currency to another without stitching together several providers?
AllUnity’s partner structure appears designed around those questions.
Banking Circle handles part of the connection to traditional banking. Flowdesk provides liquidity. Archax supplies institutional access to minting and redemption. Hercle provides FX and off-ramp capabilities. Custody, institutional trading and distribution are supported by additional partners including BitGo, Bitcoin Suisse, RULEMATCH and Galaxy.
This infrastructure-led approach is becoming increasingly competitive. Singapore-based dtcpay, for example, recently raised fresh capital to expand its stablecoin payments and merchant infrastructure, showing that investors are placing money behind the rails connecting digital currencies to ordinary commercial activity.
The FX Angle Could Matter to Corporate Treasurers
For businesses, the strongest potential use case is not necessarily holding USDAU for long periods. It may be using USDAU and AllUnity’s other currencies as temporary settlement assets.
Imagine a European company receiving euros but needing dollars to settle an overseas supplier invoice. A traditional process can involve bank operating hours, correspondent institutions and FX settlement procedures that do not necessarily run continuously.
Stablecoin infrastructure can theoretically separate the movement of value from those operating windows. Digital tokens can move around the clock, while conversion back into fiat occurs at the endpoints.
AllUnity’s multicurrency approach goes one step further by putting euro, dollar, Swiss franc and Swedish krona tokens under the same issuer and Business Mint Account.
That could make treasury operations more efficient if sufficient liquidity develops between the currencies.
It could also support a form of on-chain FX market in which regulated stablecoins increasingly act as digital representations of different fiat currencies. Instead of stablecoins serving mainly as dollars used to enter and exit crypto markets, they begin to function as settlement instruments connecting real-world currencies.
Infrastructure providers are already experimenting with related models. Cycles, for example, has been developing a private clearing network for stablecoin payments aimed at reducing the amount of capital required to settle obligations across participants.
Multichain Distribution Also Creates New Complexity
There are trade-offs.
Launching on six networks gives USDAU immediate reach, but every additional blockchain creates operational work around liquidity, custody, smart contracts, integrations and monitoring.
Stablecoin liquidity can also fragment. A token may technically exist on several chains while most real trading activity remains concentrated on only one or two. For users, the headline number of supported networks matters less than whether meaningful liquidity actually develops where they want to transact.
That makes Flowdesk’s role important. Deep two-way liquidity and reliable conversion are essential if USDAU is expected to function as business money rather than simply an issued token with limited circulation.
The same applies to redemption. Stablecoins become more useful as payment instruments when companies are confident that digital balances can reliably return to bank money at par.
The Real Test Is Whether Businesses Use the FX Rails
USDAU enters an extremely competitive dollar-stablecoin market, so circulation alone will not tell the whole story.
The more interesting metric will be whether AllUnity can generate meaningful movement between its four currencies.
If businesses begin using EURAU, USDAU, CHFAU and SEKAU together for treasury operations, supplier payments and cross-border settlement, AllUnity would be building something more defensible than a collection of fiat-backed tokens.
It would be building a regulated multicurrency payment network.
That is also where the Instant FX launch could become strategically important. The stablecoins are the assets users see on-chain, but the larger opportunity may lie in reducing the infrastructure companies need to move between currencies.
Traditional foreign exchange will not disappear because stablecoins settle faster. Businesses still need liquidity, compliance, banking access, pricing and reliable fiat redemption.
But if those components can increasingly sit behind one business account while blockchain rails handle the movement of value, the number of intermediaries visible to the customer could shrink considerably.
For AllUnity, USDAU expands the currency set. Instant FX is the feature that tries to turn that set into a network.
