Infura do not send signed transaction to the ETH mainnet network

Hi. my ether wallet test web3 version 1.2.11.
but do not sendSignedTrasaction function.

error message is ‘Error: Transaction was not mined within750 seconds, please make sure your transaction was properly sent. Be aware that it might still be mined!’

signed raw transaction body

can you help me?

thank you

Hi @hsson - welcome to the Infura community! If your transaction was not mined within 750 seconds, I would suggest increasing the gas price. If that doesn’t work, please let us know and we can help you figure out what’s going on.


I am grateful for your kindness.

This is my code sample.
Still I haven’t found a workaround. What is wrong?

let Web3Ex = function() {
this.setProvider(new this.providers.HttpProvider(;

this.GAS_PRICE = this.utils.toWei( '60', 'gwei');
this.GAS_LIMIT = 100000;
this.last_nonce = 0;
global.config.ETH.web3ex = this;
return this;


sendfee: async function( resp, addr, callback ) {
let FeeWalletAddr= this.hdwallet.feewallet_addr;
let FeeWalletPK = this.hdwallet.feewallet_pk;
let sender = this;

    let web = new web3();
    global.config.ETH.web3ex = web.setProvider(new web.providers.HttpProvider(;

    let remain = this.web3ex.eth.getBalance(addr);
    let remain_fee = this.web3ex.eth.getBalance(FeeWalletAddr);

    if(remain_fee <= 0 ) {
        resp.send(_make_error_ret({ value: remain_fee, msg: 'Fee Account balance is insufficiant. (current amount : ' + remain_fee + ')'}, 'error'));

    if(remain >= this.web3ex.TRANSACTION_FEE_WEI ) {

    let nonce = this.web3ex.eth.getTransactionCount(FeeWalletAddr, 'pending');
    let gasPrice = this.web3ex.GAS_PRICE;
    let gasLimit = this.web3ex.GAS_LIMIT;

    let amount = this.web3ex.TRANSACTION_FEE_WEI;

    const params = {
        nonce: this.web3ex.utils.toHex(nonce),
        // nonce: this.web3ex.utils.toHex(10),
        from: FeeWalletAddr.toLowerCase(),
        to: addr.toLowerCase(),
        value: this.web3ex.utils.toHex(amount),
        gasPrice: this.web3ex.utils.toHex(gasPrice),
        gasLimit: this.web3ex.utils.toHex(gasLimit),

    const tx = new ethTx( params, {chain: 'mainnet', hardfork: 'constantinople'} );

    let pkBuffer = new Buffer(FeeWalletPK, "hex");

    const serializedTx = tx.serialize();
    const txData = `0x${serializedTx.toString('hex')}`;
    params.tx = txData;
    console.log( params )

    // callback( { success: true, txid: txData, params: params} )
    .on('transactionHash', (hash) => {
        console.log( hash )
    .on('receipt', (txid) => {
        let result = { error: false, txid: txid, params: params }
    .on('error', (error) => {
        let result = { error: true, msg: error, params: params }
        callback( result )

It looks like you have 60 gwei as your gas price. According to, recommended gas prices are much higher, closer to 90 gwei. I would suggest increasing your gas price closer to that and seeing if it gets mined.

@hsson, @Leiya_Kenney is saying right, its not good to hardcode the the Gas price, Web3 offer functions to fetch current network Gas price.
