Blockchain technology has revolutionized the way we transfer value, but with innovation comes complexity. One of the most common points of confusion for crypto users is understanding ERC-20, BEP-20, and TRC-20 — terms that frequently appear during wallet transfers. These aren’t cryptocurrencies themselves, but rather token standards that define how tokens operate on different blockchains.
Understanding these standards is crucial to avoid costly mistakes — like losing funds due to incorrect network selection. This guide breaks down what each standard means, how they differ, and how to choose the right one when transferring crypto.
What Are ERC-20, BEP-20, and TRC-20?
ERC-20, BEP-20, and TRC-20 are token standards used to identify different blockchain networks, especially during cryptocurrency transfers. When you send digital assets like USDT or ETH, your wallet or exchange will often ask you to select a network — such as ERC-20, BEP-20, or TRC-20. This choice determines which blockchain will carry your transaction.
Think of these standards as unique identifiers for specific blockchains:
- ERC-20 → Ethereum blockchain
- BEP-20 → BNB Smart Chain (formerly Binance Smart Chain)
- TRC-20 → TRON blockchain
Each standard ensures that tokens follow a consistent set of rules for balance tracking, transfers, and smart contract interactions. They allow developers and users to issue and manage tokens without building an entirely new blockchain from scratch.
💡 Pro Tip: Always ensure that both the sending and receiving wallets support the same network. Sending a token via the wrong chain can result in failed transactions or permanent loss of funds.

Why Do the Same Coins Have Multiple Transfer Networks?
You may have noticed that when transferring stablecoins like USDT, you’re given multiple network options: ERC-20, BEP-20, TRC-20, Solana, and more. That’s because many tokens are issued across various blockchains to increase accessibility and optimize performance.
For example:
- Sending USDT via TRC-20 is often cheaper and faster than using ERC-20
- BEP-20 offers low fees and high speed, ideal for users within the Binance ecosystem
- ERC-20 remains widely supported but can be expensive during peak congestion
Each blockchain has its own characteristics:
| Feature | Ethereum (ERC-20) | BNB Smart Chain (BEP-20) | TRON (TRC-20) |
|---|---|---|---|
| Average Fee | High | Low | Very Low |
| Transaction Speed | Moderate | Fast | Very Fast |
| Native Coin for Gas | ETH | BNB | TRX |
Choosing the right network depends on cost, speed, and compatibility between sender and receiver.
Wallet & Exchange Support Varies by Network
Not all wallets and exchanges support every blockchain. Before initiating a transfer, confirm that both parties support the selected network.
For instance:
- Binance supports over 17 networks for USDT deposits/withdrawals, including ERC-20, BEP-20, TRC-20, Solana, Optimism, and Arbitrum
- Bybit supports 11 major networks
If you attempt to send USDT via BEP-20 to a wallet that only accepts ERC-20, the transaction may fail — and your funds could become inaccessible.
⚠️ Critical Note: Be cautious with similarly named networks. For example:
- Binance's "Polygon POS" ≠ another platform's "Polygon-ERC20"
- "Arbitrum One" on Binance may not match "Arbitrum-ERC20" elsewhere
When in doubt, use alternative networks or test with a small amount first.

What Happens If You Choose the Wrong Network?
Selecting an incompatible blockchain during transfer can lead to:
- Transaction failure
- Permanent loss of funds
This happens because blockchains cannot communicate directly. A TRC-20 token sent to an ERC-20 address won’t be recognized by the Ethereum network — it’s like mailing a letter to the wrong country without a return address.
The transaction might appear successful on-chain, but the receiving wallet won’t detect the balance. Recovery is often impossible unless the recipient controls both addresses or the service provider offers cross-chain retrieval (rare).
✅ Best Practice: Double-check the network before confirming any transfer.
How to Choose the Best Network for Crypto Transfers
When deciding which token standard to use, consider four key factors:
1. Wallet & Exchange Compatibility
Ensure both sending and receiving platforms support the chosen network.
2. Minimum Transfer Amount
Exchanges set minimum withdrawal limits per network. Some require 10–20 USDT; others allow transfers as low as 1 USDT.
3. Transaction Fees (Gas Costs)
Fees vary widely:
- TRC-20: Often less than $1
- BEP-20: Typically under $0.50
- ERC-20: Can exceed $10 during congestion
Also note: Some exchanges include service fees on top of gas.
4. Confirmation Time
How long until the transaction is finalized?
- Bitcoin (BTC): ~50–60 minutes (due to 10-minute block times + 6 confirmations)
- TRON (TRC-20): ~3 minutes
- BNB Smart Chain: ~5–15 seconds
- Solana: Near-instant (~1–2 seconds)
Faster chains use advanced consensus mechanisms like Proof-of-Stake (PoS), while Bitcoin relies on older Proof-of-Work (PoW) logic.
What Is a Token Standard?
A token standard is a set of rules defining how tokens behave on a blockchain. It enables developers — even non-coders — to launch their own tokens on existing networks without creating a new blockchain.
Before token standards:
- Launching a cryptocurrency required building a custom blockchain
- Needed significant technical expertise and resources
Now:
- Developers use standards like ERC-20 or BEP-20 to issue tokens easily
- Standards ensure interoperability with wallets, exchanges, and dApps
Each standard is tied to one blockchain:
- You can't deploy a BEP-20 token on Ethereum
- ERC-20 tokens only function on Ethereum-compatible chains
Tokens (or crypto tokens) differ from native coins like BTC or ETH:
| Feature | Native Coins (BTC, ETH) | Tokens (USDT, SHIB) |
|---|---|---|
| Blockchain | Own native chain | Built on existing chains |
| Creation Method | Mined or staked | Pre-minted via smart contracts |
| Examples | Bitcoin, Ether | USDT (ERC-20/TRC-20), DOGE |
Tokens can also be categorized:
- Fungible Tokens: Interchangeable (e.g., USDT)
- NFTs (Non-Fungible Tokens): Unique digital assets (e.g., ERC-721 or BEP-721)
Common Token Standards Used in Crypto Transfers
Here are the most widely used blockchains and their associated token standards:
1. ERC-20 – Ethereum Blockchain
Introduced in 2015 by Vitalik Buterin and Fabian Vogelsteller, ERC-20 became the blueprint for modern token development. It supports thousands of tokens like ETH, USDT, USDC, SHIB, and PEPE.
Despite high gas fees, it remains one of the most trusted and widely adopted standards.
2. Solana – High-Speed Blockchain
Solana’s native coin is SOL. Known for blazing-fast speeds (~65,000 TPS), it’s become a popular alternative to Ethereum. Major players like Visa now use Solana for USDC settlements.
Ideal for high-frequency trading and DeFi applications.
3. TRC-20 – TRON Blockchain
Developed by Tether’s parent company for its USDT stablecoin, TRC-20 offers ultra-low fees and fast confirmations. Over 50% of USDT transactions occur on TRON due to cost efficiency.
Best choice for low-cost stablecoin transfers.
4. BEP-20 – BNB Smart Chain
Launched by Binance in 2020, BEP-20 is compatible with Ethereum’s ERC-20 but runs on BNB Smart Chain. Offers fast transactions and low fees using BNB as gas.
Popular among DeFi projects and traders using Binance-affiliated services.
5. Bitcoin – Original Blockchain
Bitcoin’s blockchain only supports BTC transfers. Transactions take ~50–60 minutes due to slow block generation (one every 10 minutes) and need for multiple confirmations.
Not ideal for quick payments but remains the most secure decentralized network.
6. Lightning Network – Off-Chain Bitcoin Solution
Designed to solve Bitcoin’s scalability issues, Lightning Network enables near-instant BTC transfers off-chain. Multiple transactions are batched and settled once on-chain.
While promising, it carries risks if channels are compromised before settlement.
