I can't verify contracts on pulsechain testnet v4.

https://hardhat.org/hardhat-runner/plugins/nomicfoundation-hardhat-verify#adding-support-for-other-networks

I followed this guide but I got this error.

NomicLabsHardhatPluginError: An etherscan endpoint could not be found for this network. ChainID: 943. The selected network is pulseTestnet.

Possible causes are:
  - The selected network (pulseTestnet) is wrong.
  - Faulty hardhat network config.

I found some interesting problems.

Some contracts are verified using same code.
But some contracts are not verified using this code.

Hi @gurujustin, from your stack trace it seems you're using hardhat-etherscan, which is an older version of the hardhat-verify plugin:

at Object.getEtherscanEndpoints (D:\Software_works\blockchain\pancake-v3\pancake-v3-contracts\projects\v3-core\node_modules@nomiclabs\hardhat-etherscan\src\network\prober.ts:154:11)

Please install hardhat-verify and try again. The interface is the same, so the upgrade should be easy. You can install it by running:

npm install --save-dev @nomicfoundation/hardhat-verify

or

yarn add --dev @nomicfoundation/hardhat-verify

I'm tentatively closing this issue, but feel free to reopen if you still have issues after installing the new version.

I updated hardhat-verify module but is getting same error.

@gurujustin did you also update your Hardhat config to import @nomicfoundation/hardhat-verify and removed the import of @nomiclabs/hardhat-etherscan?

If you did and you are still having issues, we'll need a minimal reproducible example to be able to look into it.
