I can help you with that article. However, please note that I will provide a general solution and it is possible not to cover all the specific cases or the specific cases of the Metask Library.
Error: “Invalid sender” when Signingtransction in Bsctestnet – Web3
The “Invalid Sender” error usually occurs when the “Signtransction” method is called with an invalid sender. In the context of Binance Smart Chain (BSC) test, this error can be caused for a few reasons:
- Incorrect sender : The
Signtransction method is expected at a valid Ethereum address as a" sender ". However, if you try to send funds from your private key to an external wallet on BSC Testnet, they may not work.
- Invalid contract abi : If the contract abi (the binary interface of the request) is incorrect or incomplete, the "Signansction" method can throw an error.
- Web3 provider missing : Metask requires a web3 supplier to work correctly. Ensure that you have installed and configured the Correct Web3 provider for your environment.
Suggested Solution
Here is a step -by -step solution:
- Check the ABI contract
:
Make sure that the contract is exported correctly from the "contract" object in Metask.
JavaScript
Const C = contract;
Const rewardcalculatetx = c.methods.Rewardscalculat (). Call ();
- Check the sender's address : Double check the Ethereum address you are trying to send to funds to:
JavaScript
CONST PRIVATEKEY = "0XEEEEEEEEEEEEEEEEEEEEEEXAMPLE";
// replace with your real private key
const sendraddress = privatekey.tohex (); // convert to hexadecimal
IF (Senderaddress! == rewardscalculatetx.sender) {
console.error (invalid sender: $ {shipddress}! = $ {rewardcalculattx.sender});
return;
}
- Make sure the web3 supplier is installed:
Make sure that Metask has connected to the correct web3 supplier for your environment. You can check this by forgetting the "Connect" section of the Metask Settings.
- Test with a valid sender
:
Try to sign the transaction using a valid Ethereum address, such as0xyourvaliddressor 0xyourinvaliddress.
Here is an example of how you can change your code to manage these issues:
`JavaScript
Const C = contract;
Const rewardcalculatetx = c.methods.Rewardscalculat (). Call ();
IF (rewardscalculatedtx.sender! == privatekey.tox ()) {
console.error (invalid sender: $ {rewardcalculatetx.sender}! = $ {privatekey.tox ()});
return;
}
// check the ABI contract and sender
Const ABI = C.Abi;
console.log (abi: $ {json.stringify (abi)});
// get the ABI contract address
Constantaddress = abi [0].
Try {
// sign the transaction using the contract address and the private key
Constydtx = rewardscalculatetx.sign (privatekey);
console.log (signed transaction: $ {signntx});
} Catch (error) {
Console.error (transaction for signing errors: $ {error.message});
}
`
I hope this will help you solve the “Invalid Shipment” error when using Metask to sign transactions in BSC Testnet. If you have any additional questions or problems, do not hesitate to ask!
