Zolar is an access instrument for shielded ZEC. It is a Zcash wallet that runs entirely in your browser, keeps your funds in the Ironwood shielded pool, and is being built into a proof system that makes what you hold readable by programs on Solana. Your ZEC never moves and nothing is wrapped, so there is only ever one copy of your value.
Features
Zolar makes shielded ZEC useful without ever unshielding it, and it does that through six panels. They are named here the way the app names them, and each one holds a single job.
PROVE
Prove one Ironwood note is worth at least an amount, without saying which note it is
VERIFY
The reader's side of a proof, and the one panel that never asks for a wallet
SEND
Pay another Zolar user, addressed by their Solana account rather than a Zcash address
RECEIVE
Take payment at your Solana account, and hold what arrives shielded
TOOLS
The five entries below, and the only route to the words that recover this wallet
WALLET
A balance per pool, a sync that resumes, and one-step shielding out of transparent
Inside TOOLS
Five entries share one panel because they are reached for once and belong to no flow. Each opens a dialog rather than a page.
Backup & recovery
Twenty-four BIP 39 words that restore in any Zcash wallet, an encrypted vault file, and the way back in from either
Scoped viewing key
Show an auditor what came in, inside a date range they cannot walk out of
Payment disclosure
Prove one payment landed, without handing over a key that keeps reading afterwards
Memo decoder
Read the 512-byte encrypted note that rode along with a payment you received
Anchor status
The tree state a proof is built against, what the attester set posted, and how old it is
PROVE builds a proof in the browser and stops there, because nothing carries one to Solana yet. What a proof does and does not say is on The circuit, and every panel or entry above that has no machine behind it appears on the Roadmap as work.
Properties
These are true whether or not you press anything. Where the browser has to reach outside itself, the card says so and says what that party never sees.
Keys Stay In Your Browser
The seed is generated and encrypted on your device
No Accounts, No Database
Nothing about you is stored on any server
One Thin Relay
A browser cannot reach a Zcash node, so one binary carries the queries and never the keys
Oracle Pricing
The dollar figure comes from an on-chain oracle, not a website
Encrypted, Not Derived
The signature that unlocks the seed never derives it, and the twenty-four words open it without any account
Ironwood Only
Funds sit in the formally verified pool, and that is the only pool the circuit proves
Reference
These pages are the specification and the status of Layer 1. They are the only place carrying constraint counts, compute units, and the list of things that do not work yet.
