Industry stakes
Mobile is the main format for mainstream Web3. But integrating a crypto wallet into a mobile app creates specific challenges: secure private key management, signing UX that shouldn't scare users, incoming MiCA compliance, deeplinks to external wallets.
The big trap: a Web3 app that only works for crypto early adopters. The projects that break through in 2026 are the ones that make blockchain invisible for the end user.
Our approach
We integrate wallets with WalletConnect for external connections, or build secure custodial wallets when the product targets a mainstream audience. Signatures are explained, gas fees hidden when possible, errors translated into user-friendly language.
We've integrated crypto wallets into several apps in production. Our rule: if users need to understand Web3 to use your product, the product isn't ready.

We have supported many other projects. Additional detailed case studies are being prepared to share our approach and measurable outcomes.
Non-custodial (user manages keys) = maximum sovereignty but UX friction and loss risk. Custodial (you manage keys) = smooth UX but technical and regulatory responsibility.
For a mainstream audience, hybrid solutions (custodial with migration option) offer the best compromise.
Ethereum and Polygon on most projects. Solana when the case justifies it. For Ethereum L2s (Arbitrum, Base, Optimism), integration is similar and often more suitable on gas fees.
Blockchain choice is a product decision as much as a technical one — impacts UX, costs, regulation.
We integrate crypto-specialized KYC partners (Sumsub, Veriff) and prepare architectures for MiCA: PSAN registration, transaction traceability, private key governance.
MiCA is rolling out in Europe: we stay in active watch to adapt projects as it evolves.
