⚡ Quick summary (TL;DR)
Five chains: Ethereum, BNB Chain, Bitcoin, Solana, and Tron.
Seven tokens: USDT, USDC, ETH, BNB, BTC, TRX, SOL. USDT and USDC exist on multiple chains.
Same name does not mean same asset: USDT on Tron and USDT on Ethereum are two separate holdings and cannot be sent to each other directly.
Each chain needs its own gas coin: TRX on Tron, ETH on Ethereum, BNB on BNB Chain, SOL on Solana, BTC on Bitcoin.
Wrong-network funds are unrecoverable: the network must match exactly on both ends of every transfer.
📖 Overview
The Web3 Wallet is an on-chain wallet, separate from the in-app balance in the Pay tab. It spans several blockchains, and the tokens available differ from chain to chain. Getting this matrix straight prevents most transfer accidents.
🔗 The token and network matrix
Token | Available networks |
USDT | Ethereum, BNB Chain, Solana, Tron |
USDC | Ethereum, BNB Chain, Solana |
ETH | Ethereum (ERC20) |
BNB | BNB Chain (BEP20) |
BTC | Bitcoin |
TRX | Tron (TRC20) |
SOL | Solana (SPL) |
You can filter your assets by network in the wallet, and use token management to control which tokens appear in the list. Each token’s detail page shows information such as its contract address, chain, and market data.
⛽ The gas coin for each chain
Every transfer on a chain pays its network fee (gas) in that chain’s native coin. Holding USDT does not by itself let you send USDT — you also need the native coin of the chain it sits on.
Chain | Native coin (pays gas) | Common network aliases |
Tron | TRX | TRC20 |
Ethereum | ETH | ERC20, Ethereum mainnet |
BNB Chain | BNB | BEP20, BSC |
Solana | SOL | SPL |
Bitcoin | BTC | Bitcoin mainnet |
Platforms often use different names for the same chain, so the aliases above help you match them on an exchange withdrawal page. For diagnosing and fixing transfers blocked by missing gas, see Can’t send anything out of your Web3 wallet?.
📥 Choosing the network when receiving or sending
Receiving: pick the token first, then the network, and the page gives you the address for that network. When you share the address, always tell the sender which network to use.
Sending: pick the token and network first, then enter the destination. You can type the address, paste it, scan a QR code, or choose one from your address book.
Double-check: confirm the other side supports that network before submitting. Address formats can differ between chains — or look identical.
⚠️ Ethereum and BNB Chain addresses look the same
Both chains use the same 0x address format, so you cannot tell them apart by looking. Sending BNB Chain USDT to an address that only supports Ethereum will pass address validation yet may still be unrecoverable. Read the network selection carefully.
🔀 Same-name tokens do not cross chains
Direct answer: USDT exists separately on Ethereum, BNB Chain, Solana, and Tron. The price is the same, but on-chain they are four independent holdings. You cannot send Tron USDT to an address that only accepts Ethereum USDT.
Moving an asset from one chain to another needs a bridge or an exchange: send the coin to the exchange on the network it currently sits on, then withdraw it from the exchange on the network you want. That costs two sets of fees.
ℹ️ The Pay side only accepts Tron
On-chain deposits and withdrawals in MPChat Pay currently support USDT on Tron (TRC20) only. To move Web3 wallet assets into Pay, they must be USDT on Tron. See Moving assets between Pay and your Web3 wallet.
❓ FAQ
Can I put other coins into the Web3 wallet?
The wallet currently shows and manages the tokens listed above. Sending anything outside that list to your wallet address may leave it invisible or unusable in the App, so please avoid doing so.
Why is there no Tron option for USDC?
The networks available for each token follow what the wallet currently supports. USDC offers Ethereum, BNB Chain, and Solana, while USDT adds Tron. Go by the network options the App actually shows you.
Can funds sent on the wrong network be recovered?
Once funds go on-chain over the wrong network they generally cannot be recovered and will not come back on their own. This is exactly why token, network, and address all need checking before you send.
Are the Web3 wallet and Pay balances shown together?
No. They live in separate tabs with separately displayed and managed assets. Card spending draws on the Pay balance and has nothing to do with the Web3 wallet.
