Differences Between ERC20, TRC20, BEP2, and Other Tether Stablecoin Formats
When a person first encounters cryptocurrency transfers, they immediately notice: you need to choose a network. The correct choice determines the fate of your money. An error in network selection can lead to the irreversible loss of funds. Below, we will examine what the Tether stablecoin is, what its formats are — ERC20, TRC20, BEP2, BEP20, and others — and how to use them correctly.
Tether and Its Development
Tether (USDT) is one of the most popular stablecoins, pegged to fiat currencies at a 1:1 ratio. Examples: USDT — to the US dollar, EURT — to the euro, CNHT — to the yuan, XAUT — to gold. The issuer is Tether Limited, which claims that tokens are fully backed by reserves.
The idea originated in 2012, when J.R. Willett proposed issuing new cryptocurrencies on top of Bitcoin. Based on this, the open protocol Omni Layer was created — a layer on top of the Bitcoin blockchain that allows for the creation of digital assets, smart contracts, and peer-to-peer exchanges. In 2014, the Realcoin project was launched, which later became Tether.
Main Tether Networks: Where and How to Use
ERC20 (Ethereum) — the standard on which USDT appeared in 2018. It enabled compatibility with DeFi and smart contracts. The downside is relatively high network fees, especially during congestion. Addresses begin with 0x. Fees are paid in ETH.
TRC20 (Tron) — launched in 2019; it offers low fees and high transaction speed. Addresses begin with T.... TRX is required to pay fees. The ecosystem also uses TRC10 (basic token standard) and TRC721 (NFT). Supported by TronLink, MathWallet, imToken.
BEP2 (Binance Chain) — a standard without smart contracts, used for simple transfers within Binance Chain. Fees are paid in BNB. For small projects, a simplified BEP-8 standard is available. Address format: bnb1....
BEP20 (Binance Smart Chain) — the smart contract standard on BSC, compatible with Ethereum. It offers low fees and fast processing, with addresses also starting with 0x. Fees are paid in BNB.
OMNI (Bitcoin Omni Layer) — the very first USDT standard issued on Bitcoin. Fees depend on the Bitcoin network. Bitcoin address formats are used: 1..., 3..., or bc1....
TON (The Open Network) — the modern issuance of USDT as a jetton token. Fees are paid in TON, and addresses use a Base64url format, for example EQ... or UQ.... Suitable for fast transfers and dApp ecosystems on TON.

Address and Error Reminder
- TRC20 addresses always begin with
Tand look like a Base58 string of about 34 characters. The “Tx…” form is incorrect; the correct prefix isT.... - ERC20 and BEP20 look identical (
0x+ 40 hex characters). You cannot send tokens from one network to an address on another, even if the address looks the same. - BEP2: on exchanges, a MEMO is almost always required. Sending without MEMO can lead to loss of funds.
- OMNI: USDT issued on Bitcoin; the address is a standard BTC format (
1/3/bc1). - TON: addresses can be “bounceable/non-bounceable”; always follow wallet/exchange instructions.
Quick Checklist Before Sending
- Ensure the recipient’s network matches the sending network (ERC20 ↔ ERC20, TRC20 ↔ TRC20, etc.).
- Verify the address format (e.g.,
0x...for ERC20/BEP20,T...for TRC20,bnb1...for BEP2). - If using BEP2 — inсlude the MEMO (if required by the exchange).
- Make sure you have the fee token for the network (ETH / TRX / BNB / BTC / TON).
- Send a small test transfer if unsure.
How to Avoid Losing Money When Transferring
Most mistakes are related to the wrong network choice or incorrect address entry. For example, USDT on Tron (TRC20) cannot be sent to an Ethereum (ERC20) address. Another common issue is forgetting a tag (memo, destination tag) where it is required.
- sеlect the cryptocurrency and transfer network.
- Obtain the correct address for crediting in the chosen network.
- Copy and paste the address without changes.
- Ensure that sending and receiving networks match.
- Enter the transfer amount.
- Carefully double-check the address, network, and amount.
- Confirm the transaction.
- If withdrawing from an exchange, confirm the operation via the e-mail link.
Conclusion
Tether is issued on multiple networks: Ethereum (ERC20), Tron (TRC20), Binance Chain (BEP2), Binance Smart Chain (BEP20), Bitcoin Omni Layer (OMNI), and TON. The choice depends on the task: ERC20 or BEP20 are suitable for DeFi, TRC20 or TON for everyday fast and cheap transfers, and BEP2 for simple operations within Binance Chain. Always verify the network and address before sending — this is the key to keeping your funds safe.
