What Are Crypto Networks? (ERC-20, TRC-20, and More)
When you deposit or withdraw cryptocurrency, you'll often be asked to choose a network. Choosing the wrong one can result in lost funds. In this guide, CIEx Learn explains what crypto networks are, how they differ, and how to use them correctly.
This is one of the most important topics for any crypto user to understand.
What You'll Learn
In this guide, you'll learn:
- What crypto networks are
- The most common networks and their differences
- How to choose the right network
- What happens if you choose the wrong network
- How networks affect fees and speed
What Is a Crypto Network?
A crypto network (also called a protocol or chain) refers to the specific blockchain on which a cryptocurrency is transferred.
Many tokens — like USDT (Tether) — exist on multiple networks simultaneously. Each version is technically a separate token running on a different blockchain.
The Most Common Networks
ERC-20 — Ethereum Network
- Based on the Ethereum blockchain
- Widely supported by most exchanges and wallets
- Higher fees (gas), slower during congestion
- Example tokens: USDT, USDC, LINK, UNI
TRC-20 — TRON Network
- Based on the TRON blockchain
- Very low fees and fast transactions
- Popular for USDT transfers
- Example tokens: USDT, USDC, WIN
BEP-20 — BNB Smart Chain (BSC)
- Based on Binance's BNB Chain
- Fast and cheap transactions
- Common in DeFi applications
- Example tokens: BUSD, CAKE
BTC — Bitcoin Network
- Native network for Bitcoin only
- Secure but slower and higher fees
- No smart contract tokens on this network
How to Choose the Right Network
When depositing or withdrawing on CIEx:
- Check which network the receiving wallet supports
- Match the network on both sides — sender and receiver must use the same network
- Consider fees — TRC-20 is typically cheapest for USDT
- Consider speed — BEP-20 and TRC-20 confirm faster than ERC-20
💡 Example: If you're withdrawing USDT to an external wallet that only supports TRC-20, you must select TRC-20 on CIEx. Sending via ERC-20 to a TRC-20-only wallet will result in funds not being credited.
What Happens If You Choose the Wrong Network?
Sending crypto on the wrong network is one of the most common — and costly — mistakes in crypto.
- Funds may arrive on the wrong chain and be inaccessible
- Some exchanges can recover funds, but it often requires a fee and manual support
- In some cases, funds may be permanently lost
⚠️ Always verify the network before confirming any transaction.
Network Comparison
| Network | Blockchain | Typical Fee | Speed | Common Use |
|---|---|---|---|---|
| ERC-20 | Ethereum | Medium–High | Medium | Most tokens |
| TRC-20 | TRON | Very Low | Fast | USDT transfers |
| BEP-20 | BNB Chain | Low | Fast | DeFi, BNB tokens |
| BTC | Bitcoin | Medium | Slower | Bitcoin only |
Common Mistakes to Avoid
- ❌ Sending ERC-20 USDT to a TRC-20 address
- ❌ Not checking network support before depositing to a new wallet
- ❌ Assuming all wallets support all networks
✔ Tip: On CIEx, the supported networks are always listed clearly when you select a token for deposit or withdrawal. Never skip this step.
Conclusion
Crypto networks determine how and where your assets travel on the blockchain. Understanding the difference between ERC-20, TRC-20, BEP-20, and others protects your funds and ensures your transactions arrive correctly.
