ZECMON

What this is

A unified full viewing key (uview1…) lets someone read a Zcash wallet's incoming shielded notes. It cannot spend. It is not a seed phrase — if what you have is twelve or twenty-four words, don't paste it here, or anywhere that isn't your own wallet.

Give us one and we scan the chain in front of you. First backwards from the tip in 50,000-block strides, hunting the earliest note the key can see — that's the wallet's birthday. Once it's found, the bar re-scales to birthday → tip and walks forwards, lighting up every note as it passes.

That backwards walk stops at NU6 (block 3,042,000). Below there the chain scans roughly ten times slower per block, and a full sweep to NU5 takes upwards of half an hour — so if we find nothing above NU6 we offer the deeper sweep rather than quietly spending the time. It runs one at a time, in a queue, and you are shown your place in it.

Two pools, one key

NU6.3 Ironwood activated at block 3,428,143 on 28 July 2026, adding a second shielded pool alongside Orchard. From that block, consensus steers payments to you into Ironwood — same addresses, same viewing key, but the notes land in a new commitment tree that older software cannot read.

Every scan here reads both pools and reports the union, so a balance shown on this page is the whole picture. Notes in the new pool are badged ironwood in the list, and the Ironwood panel tells you which pool this key is actually receiving into — which is the only thing a scan can honestly observe. It cannot tell what wallet you run.

What we keep

Nothing. The key goes to our scanner in memory, lives as long as the scan job, and is never written to a database or a log. Close the tab and the job is cancelled.

Limits

• One scan at a time per browser — starting another aborts the first.
• Fair use per IP. A cold walk of the whole chain is real work. Hit the cap and the scanner says so, with a retry time.
• One deep sweep at a time, for everybody. Ask for one while another is running and you wait, with your position shown. Paying buys a place near the front of that queue — not a bigger scanner.
• First 50 notes listed. Every note found is drawn on the bar; the list is capped.

Heavier use

Unattended, scheduled, or more than a glance? Seneschal runs it as a service — Private Watch pings a webhook the moment funds land, and /v1/private/historical returns this same scan as JSON over x402. Fundraising instead? ziving.org.

For agents

Don't scrape this page. There are three machine surfaces:

• /agents.txt — what you can do here, in plain text
• /.well-known/agent.gopher — discovery card (Gopher-over-HTTPS)
• MCP — tools winbit32_zecmon_info, winbit32_zecmon_scan, winbit32_zecmon_scan_status
