Chain ID mismatch in EIP712 ante handler prevents Ledger use for Cosmos operations

[fadeev]

Users are currently unable to perform Cosmos send, staking, and other operations with Ledger.

The root cause appears to be a mismatch in the EIP712 ante handler:

• The chain ID is set as zetachain_7000-1
• The expected value is just 7000

This mismatch causes errors such as:

failed to parse chain-id: zetachain_7000-1: strconv.ParseUint: parsing "zetachain_7000-1": invalid syntax [zeta-chain/[email protected]/ante/cosmos/eip712.go:195]

Since the incorrect chain ID is on-chain, this cannot be resolved externally.

Does it block using Ledger as well through the CLI?
