Cold wallets store private keys offline, removing exposure to network-based attacks. We build hardware and air-gapped storage solutions for institutional investors, crypto exchanges, and businesses that hold large amounts of digital assets. Private keys never touch an internet-connected device.
Air-gapped storage architecture
Private key generation and secure element integration
AES-256 encryption for key storage
Multi-signature approval for fund access
Desktop wallets run on Windows, macOS, and Linux. We create these for expert traders and businesses that need a full-featured platform with advanced security, offline capability, and support for a large number of assets. Desktop crypto wallets can include portfolio analytics, tax reporting exports, and hardware wallet pairing.
Cross-platform support: Windows, macOS, Linux
Offline transaction signing and backup
Integration with hardware wallets (Ledger, Trezor)
Advanced portfolio management and analytics
Browser-based wallets that require no installation. Comfygen Develop web based crypto wallets for platforms that need users to access funds directly from a browser exchange platforms, DeFi protocols, and crypto payment gateways. Security is handled through SSL encryption, private key protection, and session management.
SSL/TLS encryption and secure session management
Two-factor authentication and private key protection
Cross-device access with cloud-encrypted key backup
Real-time balance display and transaction history
Custodial crypto wallets place private key management on the platform side; this is better for onboarding new users. Non-custodial wallets give users full control of their keys and are required for serious DeFi and self-sovereignty use cases. We build both, and we build hybrid models that let you offer both options within one product.
Custodial: platform-managed keys, compliance-ready KYC/AML architecture
Non-custodial: zero-knowledge key derivation, user-controlled seed phrases
Hybrid: combined UI with switchable custody modes
Multi-signature approvals for sensitive transactions in both models
Multi-sig wallets require M-of-N approvals from defined signers before any transaction executes. We implement multi-sig for corporate treasuries, crypto exchanges, and high-value wallets where single-key exposure is unacceptable. Smart contract-based multi-sig (Gnosis Safe pattern) and threshold signature schemes (TSS) are both available.
2-of-3 and 3-of-5 signature configurations
Smart contract-based multi-sig on Ethereum and EVM-compatible chains
Threshold Signature Scheme (TSS) for non-EVM chains
Audit trail for every approval and rejection
DeFi wallets connect users directly to decentralised protocols and lending, borrowing, yield farming, liquidity provision, and token swaps. We develop DeFi crypto wallets that integrate with Uniswap, Aave, Compound, and other major protocols, giving users a single interface to manage all their DeFi positions without leaving the wallet.
Integration with major DeFi protocols
Staking, yield farming, and liquidity pool management
Real-time APY tracking and portfolio analytics
Gas fee optimisation and MEV protection
We build wallets with native NFT support Crypto wallet for storage, display, transfer, and marketplace connectivity. NFT wallets handle ERC-721 and ERC-1155 tokens on Ethereum, and equivalent standards on Solana (Metaplex) and Polygon. Users can view their full NFT collection, list on OpenSea or Magic Eden directly, and manage royalty settings.

Penetration testing of wallet API endpoints
The global crypto wallet market was valued at $15.54 billion in 2025 and is projected to reach $100.77 billion by 2033, growing at a CAGR of 26.6%. Asia Pacific holds the largest regional share at 32%, driven by rising crypto adoption in India, South Korea, and Southeast Asia
Reasons Why you need to build crypto wallets?
Users want self-custody. 59% of crypto users now prefer non-custodial wallets where they control their own private keys.
Mobile is everything. 71% of crypto users prefer mobile wallets. A wallet without a strong iOS and Android app loses users to competitors that have one.
DeFi is mainstream. 198 million wallets were active in DeFi in 2025. Users expect staking, swaps, and yield farming inside their wallet, not in a separate app.
Stablecoin payments are growing fast Stablecoin payments are growing fast. Active stablecoin wallets jumped 53% year over year. Stablecoins now make up 30% of total crypto transaction volume. Any business accepting crypto payments needs wallet infrastructure to handle it.
Security is the highest-risk area in crypto wallet development. A single vulnerability in key management or transaction signing can result in total, irreversible fund loss. Every wallet we build is designed to pass a third-party security audit. Here is how we approach it:
We encrypt all wallet data, private keys, seed phrases, transaction history at rest using AES-256. In transit, all communication runs over TLS 1.3. Sensitive key material is never stored in plaintext anywhere in the system.
For wallets that manage significant assets, we implement M-of-N multi-signature signing. No single private key can move funds multiple authorised parties must approve every transaction. This eliminates single points of failure and reduces insider risk.
We integrate cold storage wallet solutions including hardware wallet pairing (Ledger, Trezor) and air-gapped signing devices for wallets that hold large reserves. Private keys in cold storage never connect to the internet. Signing happens entirely offline.
User-facing authentication combines biometric verification (Face ID, fingerprint) with TOTP-based two-factor authentication. Even if a device is stolen, fund access requires biometric + 2FA. Login sessions are time-limited and device-bound.
Our wallets include server-side anti-DDoS protection at the infrastructure layer and rate limiting on transaction signing endpoints. High-frequency abuse attempts are detected and blocked before they reach wallet logic.
For regulated products, we build KYC/AML compliance into the wallet architecture from day one — not as an afterthought. This includes identity verification integration (Jumio, Onfido, or custom providers), transaction monitoring, suspicious activity reporting, and travel rule compliance for FATF markets.
