E1011 — Transaction chain_id does not match this chain

Property	Value
Code	`1011`
Slug	`E1011`
Category	`validation` (Validation)

What happened

Transaction chain_id does not match this chain (tx={tx_chain_id}, node={node_chain_id}). This error is returned by the RPC when the transaction is submitted (HTTP 400), not in a receipt; it is produced by wrong_chain_id in core/rpc/src/error.rs and carries the same docs_url. Placeholders in braces are filled from the failing transaction.

Why it happened

The node rejected the operation with E1011 (category validation, Validation). The receipt’s why field carries the specific cause and context carries structured details, such as the values that filled the placeholders above.

How to fix

Rebuild and re-sign the tx with the node’s chain_id.
