Send Raw Transaction Ethereum infura nodejs npm

Question

I'm currently trying to implement an ethereum Node Connection to my Typescript/ Node Project.

I'm connection to the "Infura" node server where i need to sign my transaction locally. Well, anyway. I'm signing my transaction using the npm package "ethereumjs-tx" and everything looks great. When i'm using "sendRawTransaction" from web3 my response is an tx-id which means my transaction should be allready in the Blockchain. Well... it isn't

My sign Transaction Function is below.

private signTransactionLocally(amountInWei: number, to: string, privateKey: string = <PRIVATE_KEY>, wallet: string = <MY_WALLET>) {
        const pKeyBuffer = Buffer.from(privateKey, "hex");

        const txParams = {
            nonce: this.getNonce(true,wallet),
            //gas: this.getGasPrice(true),
            gasLimit: this.getGasLimit2(true),
            to: to,
            value: amountInWei,
            data: '0x000000000000000000000000000000000000000000000000000000000000000000000000',
            chainId: "0x1"
        };

        // console.log(JSON.stringify(txParams));
        const tx = new this.ethereumTx(txParams);
        tx.sign(pKeyBuffer);
        return tx.serialize().toString("hex");

    }

Used Functions in "signTransactionLocally" :

    private getGasLimit2(hex: boolean = false) {
        const latestGasLimit = this.web3.eth.getBlock("latest").gasLimit;
        return hex ? this.toHex(latestGasLimit) : latestGasLimit;
    }
    
        private getNonce(hex:boolean = false, wallet: string = "0x60a22659E0939a061a7C9288265357f5d26Cf98a") {
        return hex ? this.toHex(this.eth().getTransactionCount(wallet)) : this.eth().getTransactionCount(wallet);
    }

Running my code looks like following:

this.dumpInformations();
const signedTransaction = this.signTransactionLocally(this.toHex((this.getMaxAmountToSend(false, "0x60a22659E0939a061a7C9288265357f5d26Cf98a") / 3 )), "0x38bc48f1d19fdf7c8094a4e40334250ce1c1dc66" );
        console.log(signedTransaction);
        
this.web3.eth.sendRawTransaction("0x" + signedTransaction, function(err: any, res: any) {
            if (err)
                console.log(err);
            else
                console.log("transaction Done=>" + res);
        });

since sendRawTransaction results in console log: [Node] transaction Done=>0xc1520ebfe0a225e6971e81953221c60ac1bfcd528e2cc17080b3f9b357003e34

everything should be allright.

Has anybody had the same problem? i Hope that someone could help me. Have a nice day!

Wellspoken

I had similar issues, but in my case, i've learned that it can still generate a Tx id, but it won't actually process if the nonce is wrong. – Meliorate

Answer 1

After dealing with these issues countless times; i'm pretty sure you are sending a nonce too high.

In these cases, the node will still return you a transaction hash, but your transaction will remain in the nodes queue and not enter the memory pool or be propagated to other nodes, UNTIL, you fill in the nonce gaps.

You could try the following :

• Use getTransactionCount(address, 'pending') - to include the txs that are int nodes queue & memory pool . But this method unreliable and won't deal with concurrent requests as the node needs time to assess the correct amount at any given time.

• Keep your own counter, without relying on the node (unless you detect some serious errors).

• For more serious projects, persist your counter / per address at the level of the database with locks to handle concurrency, making sure you give out correct nonces to each request.
