When you open the Binance trading page, you will see trading pairs with the "FDUSD" suffix, such as BTC/FDUSD and ETH/FDUSD. This is the new generation stablecoin supported by Binance after the phase-out of BUSD. If you want to use FDUSD for spot trading, you first need to understand how to deposit it. First, set up your account on the Binance Official Site; for the app, tap Official Binance App; for iPhone installation, check the iOS installation guide. Below, we clearly explain the deposit networks and practical uses of FDUSD on Binance.
1. Who Issues FDUSD?
FDUSD (First Digital USD) is issued by First Digital Trust (FDT), registered in Hong Kong. Its reserve assets are 100% cash in US dollars and short-term US Treasuries, held in custody by third-party banks.
Features:
- Issued by a trust company regulated by the Hong Kong Monetary Authority;
- Reserves are publicly audited every month;
- High compliance in Hong Kong, making it suitable for Asia-Pacific institutions;
- Lower circulation volume compared to USDT and USDC, but growing rapidly.
2. Why is Binance Heavily Promoting FDUSD?
In 2023, Binance gradually phased out the original BUSD (issued by Paxos) and needed a replacement to serve as a "zero-fee stablecoin." FDUSD stepped into this role.
Specific benefits:
- Binance's main spot trading pairs BTC/FDUSD and ETH/FDUSD enjoy zero fees;
- FDUSD holders often get higher allocations when participating in Binance Launchpool;
- FDUSD withdrawal fees are lower than USDT.
3. Supported Networks for FDUSD Deposits
FDUSD is currently deployed mainly on these networks:
| Network | Address Prefix | Arrival Speed | Binance Withdrawal Fee | Use Case |
|---|---|---|---|---|
| Ethereum (ERC20) | 0x... | 2-5 mins | 3 FDUSD | Large amounts / Cross-platform |
| BNB Smart Chain (BEP20) | 0x... | ~30 secs | 0.3 FDUSD | Small amounts / Within Binance ecosystem |
| Sui | 0x... | Seconds | 0.1 FDUSD | New chain ecosystem |
Note:
- TRC20 is NOT supported;
- Both ERC20 and BEP20 addresses start with
0xbut are on different chains; - When depositing, you must select the withdrawal network that matches the chain exactly.
4. Depositing FDUSD to Binance from Other Platforms
Scenario A: Depositing from OKX
OKX now supports FDUSD withdrawals, typically using the ERC20 network. The process:
- Find your Binance deposit address (Receive Address);
- On Binance: Wallet → Deposit → Select FDUSD → Select ERC20 → Copy the address;
- Go back to the OKX withdrawal page, paste the address, and select the ERC20 network;
- Enter the amount, complete 2FA, and submit;
- Wait for 12 block confirmations (about 3-5 minutes).
Scenario B: Depositing from a Wallet (MetaMask)
If you already have FDUSD in your wallet (you may need to add the contract address manually), send it directly to your Binance deposit address. Note:
- Switch to the correct network in MetaMask (Ethereum or BSC);
- Copy the corresponding chain address provided by Binance;
- Keep a record of the transaction hash.
Scenario C: Swapping within Binance
The simplest way—if you already have USDT/USDC on Binance, you can swap it directly on the spot trading page using the USDT/FDUSD or USDC/FDUSD pairs. This is zero fee.
5. When to Use FDUSD
Practical scenarios:
- Primary coin for spot trading: Enjoy zero fees using BTC/FDUSD and ETH/FDUSD;
- Launchpool mining: Often grants higher weighting to FDUSD holders;
- "Zero-fee swapping" tool within Binance holdings: FDUSD is the preferred medium.
However, it is NOT suitable for:
- C2C deposits: There are very few FDUSD merchants, and the spread is wide;
- Cross-platform transfers: Liquidity is lower than USDT;
- Long-term holding in DeFi: The on-chain ecosystem is far less mature than USDC.
6. Risk Factors of FDUSD
- Concentration risk: FDUSD relies heavily on Binance's support. If Binance stops the zero-fee policy one day, FDUSD liquidity will drop;
- Single issuer: FDT is a single company in Hong Kong. Compared to Tether's years of operation, its resilience still needs time to be proven;
- Regulatory uncertainty: Stablecoin regulations are evolving globally. Future policy changes could affect the circulation scope of FDUSD;
- History of de-pegging: FDUSD experienced a brief drop to $0.98 in mid-2024 due to a liquidity event, though it recovered within hours.
7. How to Choose Between USDT, USDC, and FDUSD
A simplified decision tree:
- C2C deposits / Local scenarios → USDT;
- DeFi / Cross-chain long-term holding → USDC;
- Binance spot trading / Launchpool → FDUSD.
You can mix and match the three; swapping them within Binance costs almost nothing.
8. Frequently Asked Questions (FAQ)
Q: Which exchanges sell FDUSD? A: Mainstream ones include Binance, Bybit, and HTX. But Binance has the best liquidity by far.
Q: Can I recover FDUSD if I deposit it to the wrong chain? A: Like other stablecoins, it requires submitting a ticket + TXID. Recovery depends on chain compatibility. For example, accidentally depositing ERC20 to a BEP20 address has a chance of recovery.
Q: Will the FDUSD zero-fee policy be cancelled? A: Binance has not promised it will be free forever. The current policy has been running for over a year, but the future is not guaranteed.
Q: Is FDUSD related to BUSD? A: No direct relationship. BUSD was issued by Paxos and has stopped minting; FDUSD is issued by First Digital Trust and serves as a replacement.
