About this Gig
Need a secure crypto wallet for your app or startup? I can build a modern Web/Mobile wallet that lets users create/import a wallet, send/receive crypto, view balances, and track transactions with strong security practices.
What I can build
Non-custodial wallet (recommended): user holds the keys (seed phrase)
Custodial wallet (advanced): keys managed securely on server (HSM/KMS/MPC options)
Web wallet / Mobile wallet / Both
Multi-chain support (EVM, BTC, Solana, Tron, based on your requirement)
Core features
- Create/import wallet (Seed phrase / Private key)
- Send / Receive (QR + address)
- Balance & transaction history
- Token support (ERC-20 / SPL etc.)
- Gas/fee estimation + transaction status
- Biometric lock (mobile)
- Optional: WalletConnect, swaps, on-ramp, push notifications
My approach
- Confirm wallet type + chains + features
- Build wallet core + UI
- Integrate blockchain RPC/provider + indexing (if needed)
- Security hardening + testing
- Deliver source code + setup guide
If you want something like MetaMask/Trust Wallet style UX, I can match that too.

FAQ
What’s the difference between custodial and non-custodial?
Non-custodial = user holds keys (safer for you legally/operationally). Custodial = you manage keys (needs heavy security + compliance).
Which blockchains can you support?
EVM chains (Ethereum/Polygon/BSC etc.) are easiest. BTC/Solana/Tron are also possible based on scope.
Will you share the full source code?
Yes — complete source code + setup instructions.
Can you clone MetaMask/Trust Wallet?
I can build similar functionality/UX. Exact 1:1 clone depends on feature scope.
s the web wallet as secure as mobile?
Mobile can use Secure Enclave/Keystore. Web is possible but typically less secure for key storage—WalletConnect is often recommended for web.
