Questions

Is USDT0 the same as USDT?
It is the LayerZero version of USDT, moving 1:1 between the networks that support it.
How much does the bridge cost?
Only the LayerZero messaging fee, charged as part of the network fee; the USDT0 arrives in full. The fee breakdown shows it with your quote.
Can I receive on Arbitrum instead and bridge later?
