Unity Developer Needed for Blockchain error fix

I'm experiencing issues with the blockchain integration of my Unity game. Specifically, transactions are failing to process on Etherscan. This has been an ongoing issue, and I need a skilled Unity Web3 developer with experience in blockchain and smart contracts to diagnose and rectify the problem. No recent changes have been made to the smart contract, so the issue likely lies elsewhere.

Ideal Skills:
- Proficiency in Unity development
- Extensive experience with blockchain technology
- In-depth knowledge of smart contracts
- Problem-solving skills to troubleshoot transaction issues
- Familiarity with Etherscan
- Experience with Infura and Nethereum on Sepolia testnet

Please provide your bid if you believe you can help resolve this issue swiftly. Thank you.
