When navigating the world of cryptocurrency, one of the most critical yet often overlooked steps is selecting the correct blockchain network for deposits and withdrawals. For beginners, sending digital assets between wallets or exchanges can feel overwhelming — and a single mistake in network selection could lead to lost funds. Understanding how to choose the right network ensures your transactions are fast, secure, and cost-effective.
This guide walks you through everything you need to know about choosing compatible networks, avoiding common pitfalls, and optimizing your crypto transfers on platforms like OKX.
Why Network Selection Matters
Cryptocurrencies don’t exist on a single universal blockchain. Instead, each token operates on specific networks that support its protocol. For example, USDT (Tether) exists across multiple blockchains such as Ethereum (ERC20), Tron (TRC20), Binance Smart Chain (BEP20), and others. While they all represent the same stablecoin, transferring them across incompatible chains can result in irreversible loss.
👉 Discover how to safely transfer USDT across networks with confidence.
The key rule is simple: the withdrawal network must match the deposit network. If you deposit USDT using the TRC20 network, you must withdraw using TRC20. Mixing networks — for instance, withdrawing via ERC20 when you deposited via TRC20 — may cause delays or permanent fund loss.
How OKX Helps You Select the Right Network
Most major exchanges, including OKX, automatically detect and suggest the correct blockchain for supported assets. When depositing common cryptocurrencies like Bitcoin (BTC) or Ethereum (ETH), the system usually defaults to the native chain, minimizing user error.
However, for multi-chain tokens like USDT, USDC, or DAI, you’ll often be prompted to manually choose a network. In these cases, OKX displays available options such as:
- USDT-ERC20 (Ethereum)
- USDT-TRC20 (Tron)
- USDT-BEP20 (Binance Smart Chain)
- USDT-Arbitrum
- USDT-Optimism
Each option has distinct characteristics in terms of transaction speed, fees, and security.
Comparing Popular USDT Networks
To help you make an informed decision, here’s a breakdown of two widely used USDT networks:
USDT-TRC20 (Tron Network)
- Transaction Speed: Fast (~3 seconds confirmation)
- Fees: Very low (typically under $0.10)
- Best For: Small to medium transfers where cost-efficiency is key
Tron’s high throughput and minimal fees make it ideal for frequent, low-value transactions. It's especially popular among traders moving funds between exchanges quickly and affordably.
USDT-ERC20 (Ethereum Network)
- Transaction Speed: Slower during peak times (1–5 minutes average)
- Fees: Higher (can exceed $5–$10 during congestion)
- Best For: Large transfers where security and wide compatibility matter
While more expensive, ERC20 offers superior decentralization and is accepted by nearly all wallets and platforms. It's preferred for institutional movements or when interfacing with decentralized applications (dApps).

Other networks like BEP20, Arbitrum, and Optimism offer middle-ground solutions — combining lower costs than Ethereum with strong ecosystem integration.
Step-by-Step: Choosing a Deposit Network on OKX
Let’s walk through a real-world example of depositing USDT into your OKX account:
- Open the OKX app and go to the Assets tab.
- Tap Deposit > Deposit on-chain.
- Search for USDT.
- Select your preferred network (e.g., TRC20 or ERC20).
- Copy the generated deposit address.
- Go to your external wallet or exchange.
- Paste the address under Withdrawal, select the same network, enter the amount, and confirm.
⚠️ Warning: Always double-check that the withdrawal network matches your chosen deposit network. A mismatch can result in lost funds.
Common Mistakes to Avoid
Even experienced users occasionally slip up. Here are frequent errors — and how to prevent them:
- Ignoring network compatibility: Never assume all USDT is the same. Always verify which chain your recipient supports.
- Copying the wrong address: Use copy-paste functions instead of manual typing to avoid typos.
- Reusing old addresses without verification: Addresses may change after updates; always generate a new one.
- Skipping fee comparisons: High gas fees on Ethereum can eat into profits during small transfers.
FAQ: Frequently Asked Questions
Q: What happens if I send crypto using the wrong network?
A: Funds may be lost permanently if sent to an incompatible chain. Some platforms offer recovery tools, but there’s no guarantee. Always confirm network alignment before confirming any transaction.
Q: Can I change the network after initiating a withdrawal?
A: No. Once a transaction is broadcasted to the blockchain, it cannot be altered. You must cancel before confirmation — if possible — and restart with the correct network.
Q: Is TRC20 less secure than ERC20?
A: TRC20 runs on the Tron network, which uses a delegated proof-of-stake model with fewer validators than Ethereum’s decentralized consensus. While generally secure for transfers, ERC20 is considered more robust due to its larger validator base and battle-tested infrastructure.
Q: Why does OKX show multiple networks for one coin?
A: Tokens like USDT are issued across various blockchains to increase accessibility and scalability. This allows users to choose based on their priorities: speed, cost, or compatibility.
Q: Do I need to pay fees in the same token I’m transferring?
A: No. Transaction fees are paid in the native currency of the blockchain — e.g., ETH for ERC20, TRX for TRC20 — not in USDT itself. Ensure you have a small balance of the native token to cover gas.

Final Tips for Safe & Efficient Transfers
- Always start with a small test transaction when using a new network.
- Bookmark your frequently used networks for quick reference.
- Enable email/SMS notifications to track transaction status.
- Use trusted platforms like OKX that clearly display network options and warnings.
By understanding blockchain compatibility and making informed choices, you can protect your assets and streamline your crypto experience.
