Sealed on Zyn.
Anchored in Zcash.
Every epoch seals the ledger into one state root, laid down on top of the last. The operator writes those roots into ordinary Zcash transactions, so each anchored layer is pinned to a Zcash block that anyone can look up.
It runs. Open any of it.
These are the live apps, captured from their public addresses on testnet. Nothing here is a mockup.
Ask the ledger yourself.
ZynScan's API is public and needs no key. This is the newest sealed epoch, fetched when you opened this page.

Built on Zyn
Cave is the first consumer app on Zyn: Collection Z, the Cave store and the Jade launchpad. Nap is the wallet all of them talk to. Every screen below is a live capture.

Market
Built and enabledSwaps and pools inside the VM. Orders in one epoch clear together at one price, so nothing can be sandwiched within a batch. The operator still sees each order and can refuse or delay it.

What you are trusting
One operator orders transactions. Zyn is operator-sequenced, with no fraud proofs and no validity proofs.
Withdrawals depend on our custodians. Bridged ZEC is backed by ZEC in a 2-of-3 threshold vault run by the Zyn team.
Zcash keeps time; it does not check our work. It records deposits, withdrawals and anchor commitments, but does not validate Zyn state transitions. Zyn does not inherit Zcash's security.
Private from the public, visible to the operator. Who holds and trades what is not published. The operator and authorised verifiers can see it today; we are working toward a version where they cannot.
Hallmarks
Precious metal carries stamps anyone can check. These are Zyn's, and none of them needs our help.
- BACKED
Issued against the vault. The ledger publishes what it has issued per asset; the bridge checks the vault still holds it every pass, and you can compare the same figure with the vault's balance on Zcash.
- REPLAYED
Rebuilt from the journal. ZynScan replays every sealed epoch and reports whether its root matches the node's.
- ANCHORED
Written into Zcash. Once a root is anchored, changing it would contradict a Zcash block.
- SEALED EXIT
Destination kept to one reader. A withdrawal records only a hash of where money goes; the address is shown to the bridge that pays it.
