What Solidi Digital Currency Exchange does
Solidi Digital Currency Exchange, operated by Solidi Ltd (Company No. 09411526), is a UK-only cryptocurrency exchange founded in 2015 and headquartered in London (with operations associated with Cambridge). The platform enables UK retail consumers, businesses, and high-net-worth clients to buy, sell, and custody Bitcoin, Ethereum, Litecoin, and Ripple against GBP through an FCA-registered cryptoasset business (registration 928852). The platform is built around a proprietary matching engine and a self-developed cold storage custody stack originated in 2013, with 100% of customer crypto held in air-gapped offline storage (no hot-wallet pass-through, no third-party custodians), individual isolated private key options via BIP32 HD wallet architecture, in-house crypto transaction monitoring (since 2016) supplemented by third-party tooling, and AI-powered fiat fraud detection on GBP/EUR rails. The company has operated continuously for over a decade without a reported security breach.
Solidi's product surface comprises the core buy/sell exchange, an Auto Buy recurring purchase module backed by standing orders, an OTC desk handling transactions of £10,000+ (including assets not listed on the main platform), a Cold Storage Custody offering, a newly launched Business Account module for corporate clients, and a Koinly CSV export for UK tax reporting. Distribution is primarily digital self-serve (solidi.co) with content marketing, SEO, Trustpilot-driven social proof, and organic social channels; OTC and Business Accounts are supported by telephone and direct email sales respectively. Tiered onboarding (Starter £50/month with no ID → Intermediate £10,000/month → Pro £100,000/month) supports a low-friction acquisition funnel, and a 24-hour FCA-mandated cooling-off period plus a Suitability Assessment are layered on for regulated onboarding.
The revenue model is spread-based: Solidi embeds its margin in the displayed buy/sell rate rather than charging explicit transaction fees at checkout, with supplementary revenue from GBP withdrawal fees (£0.50), variable crypto network withdrawal fees, manual service fees (£5–£100 for edge-case support), and OTC price-on-execution spreads on minimum £10,000 tickets. Customer fiat funds are voluntarily safeguarded in segregated accounts held by FCA-regulated Electronic Money Institutions (OpenPayd/SettleGo Solutions and Enumis Limited). Solidi is privately held and founder-led (Jamie McNaught, founder and CEO), with no disclosed external funding rounds.
