Troubleshooting: Contract Deployment Minter Error
This article provides a detailed troubleshooting guide for resolving the "not a minter" error when deploying and minting tokens on thirdweb.
Description
This article provides a detailed troubleshooting guide for resolving the "not a minter" error when deploying and minting tokens on thirdweb.
Problem
When trying to mint tokens, users may encounter the error message "not a minter," despite having sufficient ETH balance for the transaction. This issue may be due to the wallet being used as a trusted forwarder, which prevents the successful execution of minting transactions.
Solution
Steps to Resolve:
- Check Your Wallet Configuration:
If you're using your wallet address as a trusted forwarder, this will cause all actions executed with that address to fail. The wallet is not authorized to mint tokens in this case.
- Deploy a New Contract:
The most effective solution is to deploy a new contract. Ensure that the wallet you're using is set up as the appropriate admin and minter for the new contract.
- Add a New Admin and Minter:
If you prefer not to redeploy, you can add a new admin and minter to the contract. This allows the new address to have the proper permissions to mint tokens. Make sure that the new admin address is configured correctly in the contract settings.
- Minting Smaller Batches:
If you're trying to mint a large batch of tokens, it’s also helpful to try minting smaller batches first, as this can sometimes resolve certain minting issues, such as gas limit or transaction size problems.
Alternative Method for Initial Supply:
If the issue is related to minting the initial token supply, you can use a dedicated explorer to add the initial supply directly to the contract. Here are the steps to follow:
- Add your wallet address and the amount of tokens you want to mint.
- Convert the amount to WEI (as shown in the explorer's reference guide).
- Retry the process once the initial supply is set.
Additional Tips
- Always Verify Permissions: Ensure that the contract has the necessary permissions and that the correct wallet is set as the minter.
- Deploy New Contracts Carefully: When deploying a new contract, double-check that all settings (including minter permissions) are configured as needed.
- Review Contract Code: If you continue to encounter errors, review your contract code to ensure that there are no logical issues preventing the minting process.
