I am trying to verify my deployed contract from truffle and getting "Etherscan has no support for network testnet with id 97" error. So I am working with Bscscan and I deployed my contract on bsc testnet.
How can I solve this problem?
My truffle-config.js
const HDWalletProvider = require('truffle-hdwallet-provider');
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();
const BSCSCANAPIKEY = fs.readFileSync("apikey").toString().trim();
module.exports = {
networks: {
development: {
host: "127.0.0.1", // Localhost (default: none)
port: 8545, // Standard BSC port (default: none)
network_id: "*", // Any network (default: none)
},
testnet: {
provider: () => new HDWalletProvider(mnemonic, `https://data-seed-prebsc-1-s1.binance.org:8545`),
network_id: 97,

},

}
Result:

Etherscan has no support for network testnet with id 97
Install the latest version of truffle-plugin-verify.
Now the latest version is 0.5.4.
npm install truffle-plugin-verify#^0.5.4 -D
Why this happens?
In this file (https://github.com/rkalis/truffle-plugin-verify/blob/32ab0f698b1e151849ab463357cded664c5cffa3/constants.js)
You can see the last two API_URLs (56 & 97). This is added to the upper version rather than what you installed.
const API_URLS = {
1: 'https://api.etherscan.io/api',
3: 'https://api-ropsten.etherscan.io/api',
4: 'https://api-rinkeby.etherscan.io/api',
5: 'https://api-goerli.etherscan.io/api',

I am trying to verify my deployed contract from truffle and getting "Etherscan has no support for network sepolia with chain id 11155111" error. So I am working with Etherscan and I deployed my contract on sepolia testnet.
How can I solve this problem?
My truffle-config.js
const apikeys = require("./chains/apikeys");

Plugin truffle-plugin-verify doesn't have Sepolia chain support
I added the sepolia api url and etherscan url to constants and it works
const API_URLS = {
...
11155111: 'https://api-sepolia.etherscan.io/api',
...
}
const EXPLORER_URLS = {

11155111: 'https://sepolia.etherscan.io/address',

I was migrating my contract to mumbai polygon testnet. It compiled successfully but when I run the command
truffle migrate --network mumbai
on bash it returned a segmentation fault error.
The configuration for the testnet in my truffle.config.js is as follows:
mumbai: {
provider: () => new HDWalletProvider(mnemonic, "https://polygon-mumbai.g.alchemy.com/v2/KEY"),
network_id: 80001,
confirmations: 2,
timeoutBlocks: 200,
skipDryRun: true
},
},
This is the content of my migration file:
var Tris = artifacts.require("TrisNFT");
var User = artifacts.require("UserContract");
module.exports = function (deployer) {
deployer.deploy(Tris).then(function(){
return deployer.deploy(User, { Tris.address, "0x9E7BD21f0b8e1Cc9E4bFc0C8C5d603Fd979760B6" })
});
};
I'm a newbie, and I'm currently trying to migrate a contract to mumbai from my Mac, but something is wrong. Could you please let me know identify what it is. I tried several methods, such as init truffle, but the outcome is different. It should work with truffle migrate —network mumbai --reset. When I try that, I get the following error:

Here's the code I'm running to get the balance of the contract I've previously deployed to Binance Smart Chain:
let Web3 = require('web3');
const fs = require('fs');
let web3 = new Web3('https://data-seed-prebsc-1-s1.binance.org:8545');
const contractAddress = '0x43045f0Cec750eEb70478B023885d1956588438E';
const contractAbi = JSON.parse(fs.readFileSync("scripts/contract_abi.json").toString())
const contract = new web3.eth.Contract(contractAbi, contractAddress);
contract.methods.balanceOf(contractAddress).call().then(result=>console.log(result)).catch(err => console.log(err));
This code throws me the error:

This is a general error originating from a smart contract, when the contract throws an unhandled exception.
Even though that you didn't post the contract source code, we can get some basic info about its content from the decompiled code.
It shows that there's no balanceOf() (that you're trying to call), and that the fallback() (which is used if you're trying to call an non-existing function) always throws an exception.
From here, the most likely possibility is that you meant to deploy a different contract (that contains the balanceOf() function) but mistakenly deployed this one instead.
Or if you meant to get the BNB balance (not the token balance) of the contract address, you can use the web3 getBalance() method. Example:
const balance = await web3.eth.getBalance(contractAddress);
I was also stuck with the same error and the issue was that I was deploying on the remix local address provided by remix but not with metamask. Hope it help someone.
I'm trying to deploy a contract to the ropsten testnet using truffle, but I get the following error:
Deploying 'Migrations'

When deploying to ganache locally, it works fine. Also I'm pretty sure my truffle-config.js is correct, it's the same as all the online tutorials, but since I'm here, I guess I'm not completely sure :). The address that hd-wallet is using is also correct (verified with the console.log statement in truffle-config.js) and it has 5 ETH balance, so more than enough. I have 2 migration scripts, it gives exactly the same error with each script.
truffle-config.js:
require("dotenv").config();

module.exports = {

ropsten: {

Try a different version #truffle/hdwallet-provider
Works for me with 1.2.3
npm uninstall #truffle/hdwallet-provider
npm install #truffle/hdwallet-provider#1.2.3
With the latest version (1.2.4) there was the same error (invalid sender).
According to my observation, this issue only occurs when you try to deploy any contract on ropsten testnet. If you're deploying with a local node like running with ganache-cli, it functions well even with the latest version (>1.2.3)
The reason here is they change the constructor method to add a chainId parameter to specified which chain you're signing with your transaction.
Solution: Update your code of initializing the HDWalletProvider.
ropsten: {
provider: () =>
new HDWalletProvider({
mnemonic,
providerOrUrl:
'wss://ropsten.infura.io/ws/v3/.....',
chainId: 3,
}),
network_id: 3, // Ropsten's id
gas: 5500000, // Ropsten has a lower block limit than mainnet
confirmations: 0, // # of confs to wait between deployments. (default: 0)
timeoutBlocks: 200, // # of blocks before a deployment times out (minimum/default: 50)
skipDryRun: true, // Skip dry run before migrations? (default: false for public nets )
},
This works fine with me on ropsten
Check this out:
https://github.com/trufflesuite/truffle/issues/3935
Seems that truffle may not be properly eip 155 compliant. A PR was merged to help but I don't think this issue is yet resolved from the HDWallet end.
https://github.com/trufflesuite/truffle/issues/3913
https://github.com/trufflesuite/truffle/pull/3923
I am using #truffle/hdwallet-provider 1.3.0 and still got the same error.
Got it fixed by changing the initialization of HDWalletProvider.
ropsten: {
provider: function () {
return new HDWalletProvider(
{
privateKeys: ["YourPrivateKey"],
providerOrUrl: "https://ropsten.infura.io/v3/InfuraKey",
chainId: 3,
}
)
},
network_id: '3',
}
(Replace YourPrivateKey and InfuraKey with your private key and infura api key)
As an alternative solution, inside truffle-config.js use:
const HDWalletProvider = require('truffle-hdwallet-provider');
instead of
const HDWalletProvider = require('#truffle/hdwallet-provider');
It's just another way of downgrading the #truffle/hdwallet-provider while your package.json can still have:
"dependencies": {
"#truffle/hdwallet-provider": "^1.3.1"
}
