Ultrafast Crosschain Private Payments

Existing crypto payment solutions have these problems:

1. Bridging funds takes 5 to 10 mins.
2. User funds are fragmented across many L2s.
3. Existing stealth address protocols similar to zcash, zkbob, ERC-5564 require both sender and receiver to be using the same privacy application.

1. Deposit in advance and spend later instantly.
2. User balance is global and not fragmented.
3. Private transfers work even if the sender is a normal metamask user.
