This can happen due to various reasons, and I'll provide some steps you can take to troubleshoot and potentially resolve the issue.

Fetching Gas Price from Polygon Gas Station:

Properly Estimating Gas Limit:

  • Instead of setting a fixed gas limit for your transactions, you can use tools like ethers.js or web3.js to estimate the gas limit needed for each specific transaction. This ensures that you allocate the appropriate amount of gas and avoid any out-of-gas errors during execution.

Private RPC Providers like Alchemy and Infura:

  • Private RPC providers like Alchemy and Infura can offer enhanced reliability and performance compared to public nodes. Consider using one of these private providers for a more stable and consistent deployment experience.

  • To achieve these improvements, you can write a simple script using ethers.js or web3.js that interacts with the Polygon Gas Station API to fetch the gas price, estimate the gas limit for your transactions, and then execute the contract deployment using a private RPC provider.

  • Sharing a sample script:

Nonce Management: 

The nonce of a transaction needs to be strictly sequential for each account. Make sure that the nonce you're setting is accurate and sequential. You're using a nonce tracker to manage this, but ensure that it's functioning correctly and not causing nonce gaps or duplicates.

By following these best practices, you can optimize the contract deployment process and increase the success rate of contract deployments on Mainnet or Mumbai testnet. Furthermore, you can save on gas costs and avoid unnecessary delays.
