Hi there 👋

Error "execution reverted"

I try to use "$token->name()" in a loop. It works most of the time. But sometimes i run into an error "execution reverted".
Any idea how to handle this?

This is an example transaction / address where it happens.
Transaction: https://etherscan.io/tx/0x15bc9ee5c237f381dca60c1be0e8fee470a1491c5fe62b967d9e5cf3d1c698d0
Address: 0x656acfd86be535353f0a08a327368ccf7304e819

Hello author, I have a problem！
It keeps prompting insufficient funds for gas
But there is enough ETH in the account
can you help me

insufficient funds for gas * price + value

$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

How to handle gasPrice and Limits

I'm trying to send Ethereum, thanks for the help last time, but I keep getting this error:
"{"success":false,"message":"insufficient funds for gas * price + value"}"

The message is the reason for failure. I have $1.01 worth of ETH, I know it's small but I wanted to send half of that to my other wallet to see if the transfer send() method completes successfully. Maybe the value I input is too big?

The amount is multiplied by the 18th power of 10, I assume because value is in Wei?

I can't understand the parameters.

Hello, I can't understand the parameters, why is the owner, what's going on with myapp, and there is a to address, I'm very confused please help.

TX fee (XX ether) exceeds the configured cap (1.00 ether)

Ask for help on how to set parameters. Use the default gaslimits (50000) and real-time gas (76044395808) to prompt me TX fee (XX ether) exceeds the configured cap (1.00 ether)

Got the transaction HASH, but the transaction was not successful

$token = new \Lessmore92\Ethereum\Token($contractAddress, "https://mainnet.infura.io/v3/id");
try {
$transfer_tx = $token->transferFrom($contractAddress, $from, $to, '0.0001', 'default', '700000');
dump($transfer_tx);
$transfer_tx_id = $transfer_tx->sign($privateKey)->send();
var_dump($transfer_tx_id);
}catch (Exception $exception) {
var_dump($exception->getMessage());
}

The above code gets the HASH of the transaction, 0x278610b300c70d6a61283d08020618cf24abe1fbc3e8f1ff56eb88c58bf739e6
Is this a successful transaction?
But the HASH of the transaction cannot query the data on the website

Is this something I'm using wrong here?

How to make a transfer without a specific token

Is it possible to use this library to initialize a transaction in ETH without passing a specific token or contract address?

insufficient funds for gas * price + value

insufficient funds for gas * price + value

owner_address 12 usdt
myapp_address is 0.08eth

Approve Token

It would be nice to add a function to check the amount of approved tokens for an address for a particular contract.

mb_substr(): Argument #2 ($start) must be of type int, float given

$tokeData = new Token('0xb01d449c7a740c1f29a39b46aebf4b16f9877981', $node);
$tokeData->name()

mb_substr(): Argument #2 ($start) must be of type int, float given

Looks like there is an issue with name of this token

Impossible to send approve without ETH for gas

@lessmore92 Hello mate, you state that by

//by this method we allow $myapp_address to send upto 99999 token behalf of $owner_address
$approve_tx    = $token->approve($owner_address, $myapp_address, 99999);
$approve_tx_id = $approve_tx->sign($owner_private)
                            ->send()

$owner_address allows $myapp_address to send some USDT amount to any address without $owner_address having anything but USDT in his wallet.

Well how is this possible to work while for approve() to work you have to send a transaction which needs gas (ETH)?

I tried with account only having token inside and got

message: "insufficient funds for transfer"
code: -32000

Here is a TX on etherscan showing the exact approve() method called that costs $31 😃
