ERC-20, BEP-20 and TRC-20: Token Standards and Transfer Networks

Why can the same USDT appear as ERC-20 or TRC-20? This guide explains token standards, their differences and why choosing the wrong transfer network can lose funds.

What is a token standard? What does ERC-20 mean?

A token standard is a shared set of rules for tokens on a blockchain. It specifies functions such as transfers, balance queries and approvals. A common standard lets wallets and exchanges handle compatible tokens consistently instead of creating a separate interface for each.

ERC-20 is a widely used token standard on Ethereum. ERC means Ethereum Request for Comments, and 20 is the proposal number. Many tokens are implemented as ERC-20 smart contracts. Standards concern technical token structure; tokenomics concerns supply and distribution design.

ERC-20, BEP-20 and TRC-20 compared

The names look similar, but the key difference is which blockchain network they operate on.

For example, the stablecoin USDT exists in versions on multiple networks, including ERC-20, BEP-20 and TRC-20. Versions issued on different networks must be handled as separate network assets, despite sharing the name.

Does a similar standard make networks interchangeable?

BEP-20 was modeled on ERC-20 and has a similar technical structure, but the networks differ and are not automatically interchangeable. Ethereum and BNB Chain addresses may both start with 0x; the sender and receiver must still select the same supported network.

• Matching address formats do not prove matching networks.
• Exchanges and wallets support different networks.
• Sending through a network unsupported by the destination can make recovery difficult.

Choosing the network for a transfer

A common beginner mistake is losing access to coins by selecting the wrong network. Match the sending and receiving networks. The network-transfer guide explains the procedure.

• Send a small test transfer, verify arrival, then send the main amount.
• Do not choose an unsupported network simply because its fee is lower.
• After pasting an address, visually compare the beginning and end, a basic scam-prevention check.

Key points

ERC-20, BEP-20 and TRC-20 operate on Ethereum, BNB Chain and Tron respectively. Similar names do not make different networks automatically compatible. The essential transfer rule is that the sending network must match the supported receiving network. Beginners can start with getting started and confirm transfers with small tests.
