Local Wallet
The Local Wallet is UIN Wallet's fully self-custodial mode. Your private keys are derived on-device from your seed phrase and are never transmitted anywhere.
How It Works
When you create or restore a wallet, UIN Wallet uses your seed phrase to derive up to 10 addresses per blockchain using the BIP-44 standard:
| Chain | Derivation Path |
|---|---|
| TRON | m/44'/195'/0'/0/{0–9} |
| Ethereum | m/44'/60'/0'/0/{0–9} |
All 10 addresses belong to the same seed phrase. You can switch between them freely — each has its own independent balance.
Switching Between HD Addresses
- On the Assets screen, make sure Local Wallet is selected
- Tap the Address row (shows the current address name and BIP-44 path)
- The HD address selector opens — choose a chain (TRON or Ethereum) and an address index (0–9)
- Your selection is saved and the balance updates automatically
Address #1 selected — TRON path m/44'/195'/0'/0/1
Sending from Local Wallet
When you send from Local Wallet, the transaction is signed locally on your device and broadcast directly to the blockchain. No intermediary is involved.
You will need to enter your wallet password to authorize each send. See Wallet Password for setup instructions.
Network fees (TRX for TRON, ETH for Ethereum) are automatically estimated and shown on the review screen before you confirm.
Security
- Private keys never leave your device
- The seed phrase is encrypted with your device's secure storage (iOS Keychain / Android Keystore)
- The wallet password adds an extra layer of protection for send operations
TIP
Use different address indices to separate funds or to maintain privacy across different counter-parties.
