Any update on this issue. I got the same issue when trying to send token TRC20 (USDT)
{
error: 'CONTRACT_VALIDATE_ERROR',
message: 'contract validate error : account does not exist'
}
I found the reason. I got this error because I don't have TRX on my wallet to pay the GAS fee.
is this for trc20 tx??any idea ??tnx

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.
read it here https://medium.com/tron-foundation/tron-developer-guide-account-2446633a750
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...
