Crypto Wallet Development
Introduction - crypto wallet development
This builds wallet software - key generation and storage, transaction signing, and balance/history display - for holding and moving crypto assets. Given that wallet bugs can mean irreversible loss of user funds, this is one of the highest-stakes categories of software we build, and we treat it accordingly.
We build using established, audited libraries for cryptographic operations rather than implementing key management from scratch - reinventing cryptographic primitives is where amateur wallet projects go wrong.
Why security practices here are non-negotiable
A wallet holding real user funds has a fundamentally different risk profile than typical web software - a bug doesn't just mean a bad user experience, it can mean permanent loss of money with no customer-support recovery path. We use hardware-security-module or secure-enclave key storage where appropriate, never store private keys in plaintext, and strongly recommend a third-party security audit before any mainnet launch handling real value.
We're honest that we won't cut corners on security review timeline for a faster launch - this is the one area where "ship it and fix bugs later" isn't an acceptable approach.
What's included
- Secure key generation and storage (never plaintext, hardware-backed where possible)
- Multi-chain support (Ethereum, Polygon, and other EVM-compatible chains)
- Transaction signing and broadcast with confirmation handling
- Balance and transaction history display
- Biometric/PIN app-level security layer
- Strong recommendation and coordination for third-party security audit before launch
Our process
1. Security architecture planning
Key management and storage approach gets designed and reviewed before any wallet feature development starts.
2. Build & test on testnet
Wallet functionality is built and thoroughly tested against testnets, never handling real value until security review is complete.
3. Audit before mainnet
Third-party security audit is strongly recommended and coordinated before any mainnet launch handling real user funds.
Pricing
Cost is driven heavily by security audit scope and number of supported chains, not UI complexity. Range: Rs 150,000 - 1,000,000 - indicative, final quote after discovery. Request a quote or WhatsApp +92 324 2991303.
Industries we serve
Crypto exchanges and platforms needing custodial or non-custodial wallet features, and Web3 products needing integrated wallet functionality for their users.
