Fideum

Company and ownership

Fideum Group Limited is a private company registered in England and Wales under number 14811251. Companies House dates its incorporation to April 18, 2023 and lists a registered office at 128 City Road, London. The privacy policy gives a second address, on Naugarduko street in Vilnius, Lithuania. Both active directors, Anastasija Plotnikova and Vilius Gudavicius, are Lithuanian nationals living in Lithuania.

Plotnikova is chief executive and a co-founder. She holds more than 25% of the shares, according to Companies House, as do Darren Franceschini and Kelghe D'Cruz; D'Cruz resigned as a director on August 20, 2026. In June 2025 Valereum PLC, quoted on the Aquis Stock Exchange, committed €1.7 million for a minority stake, payable in tranches through June 2026. Mastercard named Fideum overall winner of its Lighthouse FINITIV program in fall 2023.

Custody model and security

Under its Terms, last updated June 2, 2026, Fideum licenses software and does not take custody of assets on a client's behalf. The custody module is described as key-management software with configurable wallet infrastructure and policy controls, plus integrations with qualified custodians. Clients remain responsible for safeguarding API keys and signing material.

Marketing pages go further. The site cites MPC custody and HSM-backed key management, and the security page describes offline cold wallets paired with policy-controlled warm wallets for execution, with quorum approvals for sensitive operations. That page also says assets are held by licensed custodians, though it names none. Fireblocks and Blockdaemon appear among the partner logos on the homepage.

Regulation and insurance

Clause 2.4 of the Terms says Fideum does not act as a client's broker, dealer, custodian of record, exchange, payment institution or counterparty. Before activation, clients must pass a know-your-business review that includes beneficial-owner checks and sanctions screening. English law governs the agreement.

The homepage calls the platform regulated, and a Fideum Group page is billed as covering the companies and licenses behind it, yet neither page names a regulator or a registration number. Valereum's June 2025 announcement said Fideum had registered VASPs in Europe, an MSB registration in Canada and a PSP license in Australia, with a MiCA CASP license described as upcoming. As of October 2026, ESMA's interim register of authorized crypto-asset service providers listed no Fideum entity. Insurance is mentioned on the homepage and support page without a carrier or limit, and the site refers to SOC controls without citing a SOC report or an auditor.

Products and integrations

The Terms list six modules: custody and key-management software, trading and execution APIs, staking orchestration, settlement and payment orchestration, tokenization and registry tooling, and dashboards with reporting. Orders route through Fideum's APIs while the client keeps its own venue relationships, and fiat or stablecoin transfers are carried out by the client or its regulated providers. Staking orchestration covers validator selection and reward accounting across proof-of-stake networks. The website adds AML screening, KYC and KYB checks, Travel Rule support and white-label crypto products for banks, credit unions, brokerages and fintech platforms.

Asset availability depends on jurisdiction and service tier, according to the support page. Company LinkedIn posts list 11 fiat currencies, including EUR, GBP, CHF, AUD and MXN. Announced partners include FLUIDEFI, a Canadian DeFi data firm, for a white-label tokenization and reporting platform (June 2025), and Blubird, whose real-world asset marketplace uses Fideum for payments and wallet support (September 2025). Clients pay subscription fees set in an individual order form, with invoices due within 30 days.
