INTRODUCTION
This guide is for users who are using a mobile phone for crypto for the first time. You will:
- Create a wallet on your phone (OKX Wallet, Phantom, or Binance Wallet);
- Top up, buy, or transfer in USDT to your wallet;
- Get ready to connect to the RWA platform for further transactions.
Tip: For beginners, OKX or Binance is usually easier for buying and withdrawing. Phantom is ideal once you are familiar with on-chain operations.
SECTION 1 · CREATE YOUR WALLET
1. Install wallet apps
Open App Store or Google Play and download:
- OKX (exchange + Web3 wallet)
- Phantom (non-custodial Solana wallet)
- Binance (exchange with optional Web3 wallet)
Quick comparison:
- OKX Wallet: Good for beginners, easy buy & withdraw, can connect to Solana apps.
- Phantom: Non-custodial Solana wallet, on-chain only, no built-in fiat buy.
- Binance Wallet: Starts custodial, can upgrade to a Web3 private-key wallet.
2. Create wallet in OKX app
- Open OKX app → switch to “Web3 Wallet” mode;
- Tap “Create Wallet”;
- Set a secure password;
- Write down your seed phrase and store it safely.

3. Create wallet in Phantom

- Set a password;
- Write down your seed phrase and keep it offline.

4. Binance wallet & Web3 upgrade
- In Binance app, tap your avatar → open “Binance Wallet”;
- By default it’s a custodial account;
- You can upgrade to a Web3 wallet (non-custodial);
- Back up your private key / seed phrase during upgrade;
- Wallets labeled “Sol” are Solana wallets.

Security Tip: Seed phrase = full ownership. Never screenshot or upload it. Write it down and store safely.
SECTION 2 · PREPARE FUNDS (GET USDT)
1. If you already have USDT: withdraw to wallet
OKX → mobile wallet (Solana):
- In OKX app, go to Assets;
- Tap Withdraw → Crypto, choose USDT and network Solana;
- Copy your Solana address from your mobile wallet;
- Paste the address, enter amount, and submit.

- Select USDT, enter amount;
- Choose payment method and complete the order;

1. Send USDT from OKX Wallet
