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
- A small test amount of a stablecoin on Solana or Tron, where the cashier offers it
- 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) | ~$1–4 in TRX; near zero with staked energy | Under a minute | Widely supported; most exchanges offer it |
| USDT — Solana (SPL) | Under $0.01 | 5–15 sec | Cheapest route if your wallet or exchange supports it |
| USDC — Solana (SPL) | Under $0.01 | 5–15 sec | Alternative stablecoin on a 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 already use an Ethereum L2 and the cashier lists it |
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. Duel.com does not publish a fixed list of coin-and-network pairs: the cashier shows what is currently offered for each coin.

When to use each network
Tron (TRC-20) — the most widely supported USDT route
Supported by almost every exchange and wallet, with fast confirmations and a fee that does not spike with congestion. It is not free, though: a TRC-20 USDT transfer consumes Tron "energy", and a wallet without staked TRX burns roughly 6 to 13 TRX to pay for it — about one to four dollars as of 2026, payable in TRX, not USDT. Exchanges charge a flat withdrawal fee instead.
- Buy USDT on an exchange and withdraw on the TRC-20 network
- Select the Tron (TRC-20) network for USDT in the Duel.com cashier, if it is offered
- Confirm TRC-20 is selected on your wallet's send screen
- Keep some TRX in a self-custody wallet to pay the fee; it does not scale with the amount sent
Solana (SPL) — fastest and cheapest
Confirmation within seconds, fractions of a cent in fees. Ideal if you already operate in the Solana ecosystem or want the absolute lowest cost. You need a little SOL in the wallet to pay the fee.
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 and sidechain networks (Base, Arbitrum, Polygon, BNB Chain)
Lower fees than Ethereum mainnet but less universally supported, and they share Ethereum's 0x address format, which is exactly what makes a wrong-network send possible. Check the cashier 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 (destination tag), XLM (memo) and some other assets use a shared deposit address plus an extra identifier that routes the funds to your account. When the cashier shows a tag or memo, it is mandatory. Omitting it means the funds arrive but cannot be matched to you without manual help from support, which is slow and not guaranteed. Always fill it, in the wallet's dedicated memo or tag field.
Native coins with similar names
BNB lives on BNB Smart Chain (tokens there use the BEP-20 standard); the older BNB Beacon Chain (BEP-2) has been retired. 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, and a wrong-network send cannot be reversed. For stablecoins, Solana is the cheapest common route and Tron the most widely supported, where the Duel.com cashier offers them. 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.
Frequently asked questions
What happens if I send on the wrong network?
The funds leave your wallet but do not credit, and the transaction cannot be reversed. Between chains that share an address format, such as Ethereum and BNB Chain, manual recovery by Duel.com support is sometimes possible but slow and never guaranteed. Between incompatible formats most wallets refuse to send at all. Matching the network before sending is the only reliable approach.
Is USDT the same on every network?
Same name, different chains. USDT on Tron (TRC-20) and USDT on Ethereum (ERC-20) are separate tokens on separate blockchains. Once inside a platform balance they display identically, but the transfer itself must use the matching network.
Which network is cheapest for deposits?
Solana (SPL) is the cheapest common option for stablecoins, at a fraction of a cent per transfer. USDT on Tron (TRC-20) costs roughly one to four dollars of TRX from a self-custody wallet, or the exchange's flat fee. Ethereum mainnet is the least predictable and can cost far more during congestion.
Can I change the network after generating a deposit address?
No. Each deposit address is tied to the network selected when it was shown. If you change the network selector on the deposit screen, copy the address again rather than reusing the earlier one, and always send to the address displayed for the network you selected.
