SEND
Paying another Zolar user without either side seeing a Zcash address.
SEND pays another Zolar user in shielded ZEC. Neither side types a Zcash address, and neither side is shown one.
Who you pay
Another Zolar user, named by the Solana account they already have. What lands is shielded ZEC in their own pool, with nothing wrapped and nothing unshielded on the way.
The directory
Naming somebody by their Solana account needs a map from one to the other, and a public map of accounts to shielded addresses is a list of people holding ZEC.
How it works
Spending a note takes its path through the commitment tree and a proof built over that path, both in this browser and neither on a server.
That proof is the same class of work as shielding, around 16.5 seconds, with the proving key ahead of it. It is a different circuit from the shielding one, and it does not exist yet.
The directory does not exist either. The Roadmap carries both.
