Can you help a crypto business meet FCA financial promotion requirements technically?

We build the risk warnings, disclosures, and audit logging patterns commonly expected alongside FCA-compliant marketing, working alongside your UK compliance counsel.

What's the difference between custodial and non-custodial wallets?

Custodial wallets hold private keys on your behalf with easier recovery; non-custodial wallets give users full control of their private keys.

Which blockchains can the wallet support?

Bitcoin, Ethereum and EVM-compatible chains, Solana, Tron and others based on your product's needs.

Can the wallet include staking or in-app swaps?

Yes, staking, swap and on/off-ramp features are common additions we build directly into the wallet.

How long does it take to build an MVP wallet?

A focused MVP wallet typically launches in 8–12 weeks; a full-featured multi-chain wallet with swap and staking takes longer.

Cryptocurrency Wallet Development in United Kingdom

Generic wallet apps rarely fit a specific product's compliance model or user experience needs. Hurain Technologies builds custodial, non-custodial, hybrid and smart-contract (ERC-4337) crypto wallets tailored to exchanges, Web3 platforms, gaming ecosystems and remittance products — with multi-chain support, in-app swap/staking, and full white-label branding. In United Kingdom, that means building to the technical expectations of High-Value Regulated Markets: Payments and open banking integrations typically engage with the FCA's regulatory perimeter and the UK's Open Banking standard for account information and payment initiation.

The Challenge

Problems we see teams struggling with

Limited wallet options for your product

Off-the-shelf wallets don't match your compliance model, supported assets, or UX requirements.

Custody security and key management

Keys must be secured on-device or on your infrastructure without exposing users to loss.

Multi-chain complexity

Supporting multiple blockchains from one wallet interface multiplies engineering effort.

User recovery and support friction

Seed phrase recovery is user-hostile; social recovery and secure enclave options solve this.

Poor UX driving support ticket volume

Confusing transaction confirmations, unclear gas fee estimates, and cryptic error messages generate a disproportionate share of support load for consumer wallet products.
