Which asset can travel from Arbitrum to zkSync Era?
The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit zkSync Era output before depositing.

The bridge output does not automatically fund every later gas need.
What destination address should be used?
EVM 0x account address Do not substitute a Arbitrum address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Arbitrum, selecting a representation not listed by the quote, or entering an address invalid for zkSync Era can prevent normal detection or receipt.
