You can look at this USDT TRC20 API website https://www.token188.com. After setting the address that needs to be subscribed in his background, you can receive a notification of successful transfer.

thank you very much

They have some examples to interact with smart contract: https://github.com/tronprotocol/tronweb/blob/50d113ff35ab8db92cfe12d672699909ad96d2ec/demo/tron-dapp-react-demo/src/utils/blockchain.js#L20

i have trc20 still facing the same issue

same problem here. I have $15 on my address and same error. any ideas?

guys there is a solution. YOU MUST fund your address with TRX! not USDT TRC20. ONLY TRX.

Simple rules of blockchains

if you do any transaction in a blockchain you need paid gas fees for any Tx, with each blockchain coin example :

• Need TRX, in your wallet, if you submit Tx in Blockchain TRON

• Need BNB if you .. in Blockchain BINANCE

• Need ETH if you send SHIBA INU in Blockchain ETHEREUM

• For send fund from a blockchain to another (CROSSCHAIN) you need use BRIDGE in some DEXs, example :

• Transfer ETHEREUM to BINANCE CHAIN you need use bridge from UNISWAP example...

Hello, you are using private key.
But I want to send trx and trc20 with TronLink wallet.
What s the solution ?
