Owning FIUSD: Uses, Storage and Risks

FIUSD is a token issued by Sygnum Bank that represents tokenized exposure to the Fidelity Institutional Liquidity Fund (ILF), USD Fund Class G Acc. It is a fund-linked asset, not simply a dollar stablecoin: its quoted price is not proof that you can redeem one token for a fixed US dollar. The fund’s value, the token’s market price and the amount you can receive on redemption may differ.

The practical appeal is holding a blockchain-based representation of an interest linked to a USD money-market fund. That may suit an eligible holder seeking fund exposure in token form, but the token does not by itself establish your legal rights, eligibility or redemption options. Check Sygnum’s governing documents for those terms before relying on FIUSD as cash or a short-notice source of liquidity.

FIUSD is issued on Arbitrum and zkSync Era. These are Ethereum layer-2 networks, so a wallet must support the relevant network and the FIUSD token contract to display and transfer the asset. The project facts do not identify a particular wallet or publish an official wallet list; confirm compatibility with Sygnum before sending tokens.

A self-custody wallet puts control of the signing keys with you, which also means you are responsible for keeping the recovery phrase secure and checking the receiving network and address. A custodial provider may hold keys for you, but access and withdrawal rules then depend on that provider. Technical wallet support does not guarantee you are eligible to hold or transfer FIUSD. Issuer-level restrictions or fund terms may apply, so check them before moving tokens, especially between networks.

As of November 8, 2026, FIUSD’s reported circulating and total supply was about 3,998 tokens, with no maximum supply specified. The reported price was about $12,094 per token on that date. These figures can change, and a quoted market price should not be treated as a guaranteed fund redemption value.

For a token linked to a fund, supply may be affected by issuance and redemption activity, but Sygnum has not published the precise FIUSD rules for minting, burning or supply limits. Do not assume that the supply is fixed or that a change in token count directly predicts the fund’s performance. If you are comparing a wallet balance with fund documents, check the date, the token’s valuation method and whether the number refers to circulating or total supply.

FIUSD is not presented as a permissionless token that anyone can necessarily acquire through an ordinary exchange. Sygnum’s eligibility requirements and purchase or subscription process are not published in the project details described here, so confirm directly with the issuer what onboarding, identity checks, jurisdiction limits and minimums apply. Do not assume that seeing a token listed or being able to connect a wallet makes you eligible to hold the underlying fund exposure.

If you already hold FIUSD, verify the official token contract and the required network with Sygnum or your authorized service provider before receiving it. Keep transaction records and any subscription or redemption documents alongside your wallet records. This is general custody guidance, not a recommendation to acquire the token; review the fund and token terms and consider whether the restrictions fit your needs.

Moving FIUSD can involve network transaction fees, usually paid in that network’s gas token. The amount varies with network conditions and the transaction, and Sygnum does not publish a fixed FIUSD transfer fee in the project details described here. A wallet or service provider may also charge its own fee.

Do not assume you can move FIUSD between Arbitrum and zkSync Era through any bridge you find. A bridge can introduce smart-contract, liquidity and operational risks, and an unsupported route may leave tokens inaccessible or fail to preserve issuer recognition. Sygnum has not published a supported bridge or cross-network transfer process in the project details described here. Before transferring, confirm the approved route, destination network and any issuer or provider charges. A small test transfer may reduce the chance of an address or network mistake, but it does not remove bridge or eligibility risks.

FIUSD combines fund-related and crypto-specific risks. The value of the underlying money-market fund can change, and the token’s market price may not match its fund value. Redemption could be subject to eligibility rules, timing, liquidity limits or other terms; Sygnum’s redemption process and fees are not published in the project details described here. Do not treat FIUSD as a bank deposit or assume it is instantly redeemable for dollars.

You also depend on the issuer and the legal structure connecting the token to the fund. A smart-contract fault, lost keys, wrong-network transfer, service-provider failure or unsupported bridge could prevent access to tokens. Before holding FIUSD, check the legal documents, custody arrangements, audit information, transfer restrictions and redemption terms. If any of those details are unclear, do not rely on the token for money you may need immediately.

The project description identifies FIUSD as Sygnum Bank’s tokenization of Fidelity International’s Fidelity Institutional Liquidity Fund, specifically the USD Fund Class G Acc. That identifies the linked fund and issuer, but it does not by itself explain the token’s legal structure, launch date or how a holder obtains or redeems exposure.

No launch date or detailed issuance history is published in the project facts. There is also no stated maximum supply. If you need to assess how the product has changed over time, look for dated issuer documents covering the fund, token contracts, eligibility, transfer rules and redemption procedures. A token price history alone cannot establish the history of the legal rights attached to FIUSD or whether those rights have changed.
