Introduction
UIN Wallet is a self-custodial USDT wallet for iOS and Android that supports both the TRON (TRC-20) and Ethereum (ERC-20) networks. It is designed for fast, secure, and simple USDT transfers without relying on a third-party custodian.
Key Concepts
Wallet Modes
UIN Wallet offers two wallet modes you can switch between at any time:
| Mode | Description | Best For |
|---|---|---|
| Local Wallet | Fully self-custodial. Private keys are derived locally from your seed phrase and never leave your device. | Privacy-conscious users who want full control |
| Cloud Wallet | A backend-managed wallet address. Withdrawals are queued for backend review before on-chain payout. | Users who prefer a simplified custody experience |
Supported Networks & Tokens
| Network | Token | Standard |
|---|---|---|
| TRON | USDT | TRC-20 |
| TRON | TRX | Native |
| Ethereum | USDT | ERC-20 |
| Ethereum | ETH | Native |
HD Wallet (Local Mode)
In Local Wallet mode, UIN Wallet generates up to 10 addresses per chain from your single seed phrase using the BIP-44 derivation standard:
- TRON:
m/44'/195'/0'/0/{index}(index 0–9) - Ethereum:
m/44'/60'/0'/0/{index}(index 0–9)
You can switch between these addresses at any time from the HD Address selector on the home screen.
Quick Start
- Create a new wallet — generates a fresh 12-word seed phrase
- Restore an existing wallet — import with your existing seed phrase
- Once your wallet is set up, you land on the Assets screen to view balances and recent transactions
TIP
If you already have a TRON or Ethereum wallet elsewhere, you can import it into UIN Wallet using your existing 12-word seed phrase.
Important
UIN Wallet is non-custodial in Local Wallet mode. If you lose your seed phrase, your funds cannot be recovered by anyone — including UIN. Always back it up in a safe, offline location.
