---

## PR-Codex overview
This PR focuses on updating the handling of transactions for the `sophon` testnet, specifically for zk chains. It introduces a special case for transactions that ensures the use of an EIP-712 transaction format along with a paymaster.

### Detailed summary
- Removed the general check for zk chains on testnets.
- Added a specific condition for the `sophon` testnet (chain ID `531050104`).
- Ensured that transactions on the `sophon` testnet always use EIP-712 format and include paymaster data.
- Simplified the transaction handling by removing unnecessary error handling logic.
