Most decentralised apps lose people at the first screen: connect a wallet, approve a transaction they do not understand, pay a fee in a token they do not own. The London teams that get traction design the experience for someone who has never used crypto, using embedded wallets, sponsored transactions and plain language, while keeping the decentralised parts where they add value.
A dApp is still a product used by people in the UK, so ordinary law applies to the parts you run. The website and front end collect data subject to UK GDPR and PECR, and front end analytics need consent. Where your app facilitates exchange or custody, FCA registration questions arise, and promotions of the underlying tokens fall under the cryptoasset financial promotions rules. Some teams geoblock certain features for UK users while they work through this, which should be a deliberate decision rather than an accident.
Cost depends on how much logic lives on chain versus in conventional servers, wallet onboarding approach, indexing and data layers, and the number of chains supported. Ask a provider how a new user gets from landing page to first transaction, how they index blockchain data for fast loading, how front end security is handled, and how upgrades to contracts and interface are coordinated. Frenchy Digital tests onboarding with people who do not own crypto.
