Quick answer
The network is the single most important choice in a crypto deposit, and the one most likely to cause a total loss. The coin ticker on screen — USDT, USDC, ETH — is only half the story. The other half is the chain it travels on, and that chain must match on both sides of the transfer exactly.
Why networks exist and why they matter
Blockchains are separate ledgers. Ethereum, Tron, Solana, and Bitcoin each maintain their own transaction history. A token can be issued on multiple chains simultaneously — same name, different underlying infrastructure.
Key facts
- Golden rule
- Network on deposit screen = network in your wallet
- Most common mistake
- Right coin, wrong network
- Safest first deposit
- Stablecoin on Tron or Solana
- If wrong network sent
- See wrong network deposit guide
How to read the deposit screen
Select your coin
Choose the asset you hold in your wallet — USDT, BTC, ETH, etc.
Read the network options
Below or beside the coin selector, the platform lists available networks for that coin. There may be one option or several.
Select the network that matches your wallet
If your wallet holds USDT on Tron, select TRC-20. If it holds USDT on Solana, select SPL. Match exactly.
Copy the address generated for that network
The address changes when you change the network. Copy it after selecting the correct network, not before.
Set the same network in your sending wallet
Your wallet's send screen has its own network selector. It must match what you chose on the deposit screen.
Network comparison for common deposit scenarios
| Feature | Fee | Speed | When to use |
|---|---|---|---|
| USDT — Tron (TRC-20) | ~$0.01–1 | 30–60 sec | Default choice for most users |
| USDT — Solana (SPL) | ~$0.001 | 5–15 sec | If you already hold SOL ecosystem tokens |
| USDC — Solana (SPL) | ~$0.001 | 5–15 sec | Alternative stablecoin on fast chain |
| USDT — Ethereum (ERC-20) | $1–20+ | 2–10 min | Only if funds are already on Ethereum |
| USDC — Base / Arbitrum | $0.01–0.50 | 1–3 min | If you use Ethereum L2 already |
For native coins (BTC, ETH, LTC, SOL), the network is usually implicit — Bitcoin goes on Bitcoin, Ethereum on Ethereum. The multi-network problem applies mainly to tokens like USDT and USDC.

When to use each network
Tron (TRC-20) — the default for stablecoins
Widely supported, very low fees, fast confirmations. If you are buying USDT specifically to deposit, TRC-20 on Tron is the standard recommendation for most users.
- Buy USDT on an exchange and withdraw on TRC-20 network
- Select TRC-20 on the Duel deposit screen
- Confirm TRC-20 is selected in your wallet send screen
- Fee is typically under $1 regardless of amount
Solana (SPL) — fastest and cheapest
Sub-second confirmation, fractions of a cent in fees. Ideal if you already operate in the Solana ecosystem or want the absolute lowest cost.
Ethereum mainnet (ERC-20) — use only when necessary
High fees that can exceed small deposit values. Use ERC-20 only when your funds already sit on Ethereum and moving them to a cheaper chain would cost more than the deposit fee savings.
Layer 2 networks (Base, Arbitrum, Polygon)
Lower fees than Ethereum mainnet but less universally supported. Check the deposit screen for availability before assuming support.
Depositing from an exchange
Exchanges have their own network selector on the withdrawal screen, separate from the platform's deposit screen. Both must match.
| Step | Where | What to check |
|---|---|---|
| 1 | Exchange withdrawal | Network = TRC-20 (or your chosen network) |
| 2 | Deposit screen | Network = TRC-20 (same) |
| 3 | Exchange address field | Pasted address from deposit screen |
| 4 | Exchange memo field | Fill if deposit screen shows a memo |
- Selecting ERC-20 on the exchange but TRC-20 on the deposit screen
- Assuming the exchange defaults to the cheapest network
- Copying an address before selecting the final network
- Sending a token your wallet labels differently from the deposit screen (e.g. 'Tron' vs 'TRC-20')
- Using a network the platform temporarily suspended — check for notices
Special cases
Memo and tag networks
XRP, XLM, and some other assets require a destination tag or memo in addition to the address. The deposit screen will show this field. Omitting it means manual recovery. Always fill it.
Native coins with similar names
BNB exists on BNB Chain (BEP-20) and historically on other chains. SOL is native to Solana. Confirm the deposit screen's expected chain before sending.
If you already sent on the wrong network
Do not send a second transaction hoping to fix it. See wrong network deposit for recovery steps and what to expect from support.
Summary
The network must match exactly between your wallet and the deposit screen. For stablecoins, prefer Tron or Solana for low fees and fast confirmations. Use Ethereum mainnet only when your funds are already there. Select the network before copying the address, set the same network in your wallet, and test with a small amount on any route you have not used before.
