Method not supported

The eth_sendRawTransaction method is not available on TRON’s /jsonrpc endpoint. TRON’s JSON-RPC implementation provides limited Ethereum compatibility for read operations only.To broadcast transactions on TRON, use the native broadcasttransaction method via the /wallet endpoint.

​
Why this method is not supported

TRON’s JSON-RPC endpoint does not support transaction submission methods because:
  • TRON uses a different transaction format (Protobuf) than Ethereum (RLP-encoded)
  • TRON addresses use Base58 encoding natively, not hex
  • Transaction nonces work differently on TRON

​
Alternative: Use TronWeb.js

To send transactions on TRON, use TronWeb.js with your Chainstack node: 
const { TronWeb } = require('tronweb');

const tronWeb = new TronWeb({
    fullHost: 'YOUR_CHAINSTACK_ENDPOINT',
    privateKey: 'YOUR_PRIVATE_KEY'
});

async function sendTRX() {
    const transaction = await tronWeb.transactionBuilder.sendTrx(
        'RECIPIENT_ADDRESS',
        1000000, // Amount in SUN (1 TRX = 1,000,000 SUN)
        tronWeb.defaultAddress.base58
    );

    const signedTx = await tronWeb.trx.sign(transaction);
    const result = await tronWeb.trx.sendRawTransaction(signedTx);

    console.log('Transaction ID:', result.txid);
}

sendTRX();
where YOUR_CHAINSTACK_ENDPOINT is your TRON node base endpoint without the /jsonrpc, /wallet, or /walletsolidity postfixes. See also:
