Go Ethereum Evmone T8N Rejects Transactions With Chainid 0Xff P
System ArchiveGo Ethereum Evmone T8N Rejects Transactions With Chainid 0Xff P Symptom Users observe that transactions are being rejected by Go Ethereum Evmone T8N when the chainId is greater than 0xFF, which is parsed as a uint8 value, resulting in failed transaction submissions. Technical Root Cause The error occurs due to the chainId being represented as a uint8 (8bit unsigned integer) in the Evmone T8N implementation, limiting its maximum value to 0xFF (255). Any chainId value exceeding this limit is rejected. Manual Overrides To resolve the issue, consider the following steps: Update the Evmone T8N configuration to support uint16 or uint32 for chainId representation. Modify the transaction submission script to ensure chainId values are within the supported range. Use a custom transaction handler to preprocess transactions and adjust chainId values as needed. json { "config": { "evmone": { "t8n": { "chainIdType": "uint16" } } } } For more complex adjustments, consider using an external console for finegrained control over the transaction processing pipeline.
