| A coin for fees in Arbitrum One | Not needed to receive | Often needed, or the funds cannot be claimed or moved on |
| Timing | After confirmations in OP Mainnet (Optimism); the order page tracks it | Depends on the bridge and the load of both networks |
| Who holds the funds meanwhile | RubyCash for the life of the order, with an AML check | The bridge contract or its validators |
