Crypto Wallet & Custody Development in Poland: market overview

How key sectors in Poland use crypto wallet & custody development
Crypto Wallet & Custody Development for Fintech
Fintech businesses in Poland usually need secure onboarding, ledgers that reconcile to the cent, real-time payments and audit-ready reporting. For them, our crypto wallet & custody development typically starts with multi-chain support (bTC, ETH, EVM L2s, Solana, Tron and stablecoins) and adds compliance hooks as the platform grows. Progress is tracked on onboarding completion rate and time to approve an application.
Crypto Wallet & Custody Development for E-commerce
E-commerce businesses in Poland usually need fast storefronts, omnichannel inventory, loyalty and frictionless checkout. For them, our crypto wallet & custody development typically starts with dapp connectivity (walletConnect, swaps, staking and NFT views) and adds non-custodial wallets as the platform grows. Progress is tracked on checkout conversion and stock accuracy.
Crypto Wallet & Custody Development for Gaming
Gaming businesses in Poland usually need scalable game backends, player wallets, live-ops tooling and anti-fraud controls. For them, our crypto wallet & custody development typically starts with compliance hooks (address screening and travel-rule integration) and adds mpc custody as the platform grows. Progress is tracked on daily active players and retention day 7.
Crypto Wallet & Custody Development for Shared services
Shared services businesses in Poland usually need fast release cycles, scalable multi-tenant architecture and extra senior engineering capacity. For them, our crypto wallet & custody development typically starts with non-custodial wallets (seed-phrase and social-recovery wallets for iOS, Android and browser) and adds policy engine as the platform grows. Progress is tracked on release frequency and customer churn.
Example: crypto wallet & custody development for a gaming business in Kielce
Consider a gaming company in Kielce (trade fairs and manufacturing). A typical crypto wallet & custody development engagement would start with multi-chain support, then dapp connectivity, and finish the first release with compliance hooks — usually within 2–4 months.
Payments would run through Cards, data would be handled under EU GDPR, and success would be measured on daily active players, retention day 7 and payment success rate.
Example: crypto wallet & custody development for a e-commerce business in Łódź
Consider a e-commerce company in Łódź (bpo, logistics and textiles). A typical crypto wallet & custody development engagement would start with non-custodial wallets, then mpc custody, and finish the first release with policy engine — usually within 3–5 months.
Payments would run through Cards, data would be handled under EU GDPR, and success would be measured on checkout conversion, stock accuracy and repeat-purchase rate.
