Understanding Web3 surgery with metamask
As a creator of Web3, you probably know the basics of communication with Ethereum Smart contracts and operations. Sometimes, however, you can encounter mistakes by trying to perform unsuccessful operations using the API Web3 Web3. In this article, we will delve into the T3 error code from the unsuccessful specificity of Web3 operations.
What is T3 surgery?
Ethereum Each operation has three different states:
0x00
: Serd
0x01
: failure (e.g. due to the wrong signature)
- 0x02
: he came back
The "T3" error code corresponds to the status of 2 failures.
Operations Metamask and Web3
Metamk is a popular browser extension that allows you to communicate with the Ethereum block circuit without direct connection to the local computer. Thanks to the metam, you can perform operations as in the website's context menu or by clicking the Send button.
Download the T3 error code from unsuccessful operations
To eliminate unsuccessful operations and get the T3 error code, follow the following steps:
Step 1: Log in to Metamask
Make sure you are logged in to your Metamk account. You can do this by clicking the Metamk icon (usually presented as a compass) or reaching the settings menu and choosing "accounts".
Step 2: Useweb3.eth.Getransactionwith the" Status "option
Try to use web3.eth.gettransaction to get information about surgery, including an error code. Here is an example:
Javascript
Const Web3 = New Web3 (Window.ethereum);
// Try surgery
Async tritting function () {
Const tx = wait web3.eth.transaction ("MysmartContraction", {{
From: "Your caretaker",
Gaslimit: 2000,000,
Purchase: 20, // or other value
});
if (tx.status) {
Console.log (Successful operation! Status: $ {tx.status}
);
Return TX;
} Otherwise {
// Try to get the T3 error code
Const Transactondets = I’m waiting for web3.eth.getransaction (tx.id);
If (carmaceals.status == ‘0xt3’) {
Console.log (“Error code T3 was received!”);
Return operation to obtain detailed information;
}
}
// Zero return for an unsuccessful or unknown operation
Null return;
}
`
Step 3: Use web3.eth.getransactionrecypt
t with the” status “option
Alternatively, you can use web3.eth.getransactionrecypt to get detailed information from the surgery. In this case, you can search for the T3 error code:
`Javascript
Const Web3 = New Web3 (Window.ethereum);
// Try surgery
Async tritting function () {
Const tx = wait web3.eth.transaction ("MysmartContraction", {{
From: "Your caretaker",
Gaslimit: 2000,000,
Purchase: 20, // or other value
});
if (tx.status) {
Console.log (Successful operation! Status: $ {tx.status}
);
Return TX;
} Otherwise {
Const Guipip = Wait for web3.eth.getransational (tx.hash);
If (guiputing.error && gupt.eror.code == ‘t3’) {
Console.log (“Error code T3 was received!”);
Return of the receipt;
}
}
// Zero return for an unsuccessful or unknown operation
Null return;
}
`
Application
When taking these steps, you should be able to scan the T3 error code from unsuccessful operations using the AP3 AP3 interface. Remember to optimize the code to manage various scenarios and edges.
