|---|---|---|
| What lands at your address | USDT in OP Mainnet (Optimism) | Depends: in some networks it is the bridged version of the token |
| Wallet and signatures | Not needed: the coins go to the address from the order | Needed: connect the wallet and sign contract transactions |
| A coin for fees in OP Mainnet (Optimism) | Not needed to receive | Often needed, or the funds cannot be claimed or moved on |
| Timing | After confirmations in Arbitrum One; 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 |
