EIP-712 signed transactions have a few quirks that make them much harder to submit correctly than an ordinary cosmos transaction.

  • The ExtensionOptionsWeb3Tx is required
  • Submitting a signature when an ExtensionOptionsWeb3Tx is present will reject the message
  • It is possible to get the EVM Chain ID, Cosmos Chain ID, Account Number, and Account Sequence incorrect
  • EIP-712 messages must be submitted as Legacy Amino encoded messages
  • The documentation should offer very clear explanations on how to submit
