# Known non-issues
These are issues that appear like they might be a problem, but really aren't.
Deposit transactions don't have a chainId on L2.
Deposit transactions (opens new window) are transactions added to the L2 blockchain as part of the block derivation process. These transactions come from a dummy address and don't have a signature. Because in Ethereum the chainID is encoded as part of the signature, this means there is no recoverable chainID for these transactions.
This is not a problem because the only source of deposit transactions is the block derivation process. There shouldn't be a need to recover the chainID.
