How this differs from a classic bridge

	RubyCash	Classic bridge
What lands at your address	Native ETH or ordinary Arbitrum One tokens	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 Arbitrum One	Not needed to receive	Often needed, or the funds cannot be claimed or moved on
Timing	After confirmations in Ethereum; 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
