Which network for USDT and USDC? Tron, Ethereum, BNB Chain, Solana and more

USDT and USDC exist as separate tokens on many blockchains. A merchant’s checkout asks for one specific network, and the payment only works if you send on that one. This page explains how the names map to networks and how to read an address. It is general information about payment mechanics, not financial advice, and it says nothing about prices.

Network names you will see

Checkout says	Network	Address looks like
ERC-20	Ethereum	starts with 0x, 42 characters
TRC-20	Tron	starts with T, 34 characters
BEP-20	BNB Smart Chain	starts with 0x, 42 characters
Polygon, Arbitrum, Optimism, Base	Ethereum-compatible networks	starts with 0x, 42 characters
SPL	Solana	32–44 letters and digits, no 0x

The same 0x address works on many networks

Ethereum, BNB Smart Chain, Polygon, Arbitrum, Optimism and Base all use the same address format. A wallet will not stop you from sending to a 0x address on the wrong one of them, and the address alone does not tell you which network the merchant is watching. Choose the network from the checkout page, never from the look of the address.

Choosing between networks the merchant offers

• Use a network your wallet or exchange account supports for withdrawals.
• Check that you hold a little of the network’s own coin to pay the transfer fee (for example TRX on Tron, ETH on Ethereum, BNB on BNB Smart Chain, SOL on Solana). A transfer cannot be sent without it.
• Fees and confirmation times differ by network and change over time; the checkout or your wallet shows the current fee before you confirm.

Merchants by network

Each listing states the networks the merchant says it accepts. Examples for hosting: USDT on Tron, USDT on Ethereum, USDT on BNB Smart Chain, USDT on Solana.
