Hi,
You can set custom parameters for gasPrice and gasLimit as 4th and 5th parameters.

Have a look at the approve method definition:

approve(string $ownerAddress, string $spenderAddress, string $amount, string $gasLimit = 'default', string $gasPrice = 'default')

$token = new USDT("https://mainnet.infura.io/v3/8038c7c7********");

$owner_address = '0x1d64720e43342bdd0E824e1dadEF';
$myapp_private = '0xbf15a4a052a3b59c1a55988e8a1e35056fbfacf94ce';
$myapp_address = '0x907Dc5716029B907BfFB223f0A*******';
$to_address = '0x907Dc5716029B907BfFB2*******';

$transfer_tx = $token->transferFrom($myapp_address, $owner_address, $to_address, 1);
$transfer_tx_id = $transfer_tx->sign($myapp_private)->send();

How to solve this please？

Uncaught RuntimeException: insufficient funds for gas * price + value

[lessmore92]

insufficient funds for gas * price + value

This error usually happens, when the gas price and gas limit parameters value are wrong; in this library, there is a default value for those, But based on time and network (ETH network) gas price needs to be adjusted. Also gas limit is different for various methods.

You can search and learn more about gas price and gas limit, then in all methods of this library, you can set the correct value for these.

hi ,
// transferFrom

   public function transferFrom(string $spender, string $from, string $to, string $amount, string $gasLimit = 'default', string $gasPrice = 'default',string $nonce = '')
  {

    $amount = Number::scaleUp($amount, $this->decimals());
    $data   = $this->buildTransferFromData($from, $to, $amount);
    if(empty($nonce)){
        $nonce  = Number::toHex($this->getEth()
            ->getTransactionCount($spender, 'pending'));
    }

    if (strtolower($gasLimit) === 'default')
    {
        $gasLimit = $this->getGasLimit('transferFrom');
    }
    if (strtolower($gasPrice) === 'default')
    {
        $gasPrice = $this->getSafeGasPrice();
    }

    return (new TransactionBuilder())
        ->setEth($this->getEth())
        ->to($this->contractAddress)
        ->nonce($nonce)
        ->gasPrice("200000000000")
        ->gasLimit("100000")
        ->data($data)
        ->amount(0)
        ->build()
        ;

@jucci1887 Does the spender wallet have enough balance to pay the transaction fee?
