At the forefront of cryptocurrency wallet development, we blend innovation with robust security to shape the future of digital asset management. Multi-chain, DeFi-ready, and fully white-label.
A cryptocurrency wallet is a digital tool that allows users to securely store, manage, and transact with cryptocurrencies. Fenizo builds production-grade wallets available as web apps, mobile apps, browser extensions, or hardware-compatible solutions for startups, enterprises, and exchanges.
Deep domain knowledge means we hit the ground running in your vertical.
Advanced capabilities and integrations that power every solution we deliver.
Multi-signature authentication, biometric login, registry login, and layered encryption protection.
Seamless token swaps across chains with live conversion tracking and minimal slippage.
View, transfer, and manage NFTs across EVM chains and Solana directly inside the wallet.
Built-in staking, yield farming, and DeFi protocol access with one-click approvals.
Native interaction with ERC-20, BEP-20, and custom token contracts.
KYC verification, transaction monitoring, GDPR-compliant data handling, and audit logs.
A transparent, proven methodology honed across 200+ projects.
Define supported chains, token standards, wallet types (custodial vs. non-custodial), and compliance needs.
Design key management strategy, blockchain node setup, API layer, and security model.
Build wallet core — transaction signing, balance fetching, DeFi hooks, and NFT indexing.
Third-party penetration testing, smart contract audit, and OWASP vulnerability assessment.
End-to-end transaction testing on mainnet and testnet, load testing, and device compatibility.
White-label deployment, app store submission, and ongoing node maintenance.
Single wallet interface managing assets across Bitcoin, Ethereum, BNB Chain, Solana, and more.
Browser-extension and mobile wallet with native dApp browser and DeFi protocol integration.
Store, display, and transfer NFTs with metadata rendering and multi-chain NFT support.
Fully branded wallet solution — your logo, your colour scheme, your feature set. Deploy in weeks.
Flutter-built mobile wallet with biometric unlock, QR scanning, and push notifications.
Chrome/Firefox browser extension wallet with hardware wallet compatibility (Ledger, Trezor).
A crypto wallet script is a ready-to-deploy codebase for building a secure digital wallet. It handles key management, transaction signing, balance tracking, and multi-chain support saving months of development time.
We support all major chains including Bitcoin, Ethereum, BNB Chain, Solana, Polygon, Avalanche, TRON, and any EVM-compatible network. Custom chain integration is available on request.
We build both. Non-custodial wallets give users full private-key ownership. Custodial wallets use enterprise-grade HSM or MPC key management, ideal for exchanges and fintech platforms.
We implement multi-sig, biometric authentication, hardware wallet compatibility, smart contract audits, penetration testing, and encrypted key storage plus KYC/AML compliance tools.
Yes. Our white-label wallet solution is fully customisable with logo, colour scheme, feature set, and domain. We also provide the source code for enterprise clients.
