A ViaBTC Watcher URL is a shareable link that lets someone view mining-account information without logging into the account or gaining permission to modify it. It is useful when a hosting-site technician, business partner, or maintenance team needs operational visibility without the owner's login credentials. ViaBTC's Watcher introduction describes this separation between monitoring and account control.

What Data Can a Watcher See?

Watcher URLs support monitoring hashrate and mining earnings, as described in ViaBTC's feature announcement. The owner sets permissions when creating a link, so recipients should check the information available through their particular link rather than assume every link exposes the same data.

Before sharing, review the permission options in the creation screen and choose the scope needed for the recipient's task. A pool dashboard does not provide access to the ASIC's local management interface.

What a Watcher URL Cannot Do

ViaBTC states that a Watcher URL does not grant permission to modify the account. A recipient cannot use it to change withdrawal addresses or account security settings. Watcher URL documentation

The ViaBTC App also supports configuring alerts through a Watcher URL. This notification capability does not grant control over the mining account.

Watcher URL vs. Main Login vs. API Key

These access methods serve different purposes:

For automated integrations, use ViaBTC's documented API rather than treating a Watcher URL as an API credential. The Pool API documentation lists endpoints for account information, hashrate, and earnings data.

ViaBTC's API Authentication documentation requires an IP whitelist before calling the API. A sub-account inherits the primary account's whitelist when its own whitelist is empty. Keep the API key and secret key secure, as instructed in the API setup guide.

Understanding the Pool Data Shown Through a Watcher URL

A recipient viewing hashrate through a Watcher URL is looking at pool-side figures. ViaBTC calculates real-time pool hashrate as an average over the preceding 10 minutes and daily pool hashrate over the preceding 24 hours. ViaBTC's hashrate explanation

A miner's local display may use a different averaging period and refresh more frequently. Refresh frequency describes how often the display updates; it does not identify the period used to calculate the average. Differences in calculation methods, averaging periods, and refresh timing can therefore produce different readings. A temporary discrepancy alone does not establish a hardware fault or pool-connection problem.

This matters for recipients who rely on the pool dashboard and cannot inspect the ASIC directly. Worker status, hashrate, and any rejection-rate figures available through the link provide different signals and should be interpreted together.

Alerts Available Through a Watcher URL

The ViaBTC App supports Watcher URL alerts for worker-offline and high-rejection-rate conditions. Its alert guide documents these check intervals:

• Worker offline: every 10 minutes.
• Worker rejection rate: every hour.

In the App, open My → Watcher → Favorites, tap the edit icon, select Alert Settings, and choose the relevant account and alert types. An optional Do Not Disturb period suppresses alerts during the selected hours. This alert feature is available only in the ViaBTC App.

The intervals describe how often conditions are checked, not a guaranteed notification-delivery deadline.

Creating, Sharing, and Revoking a Watcher URL

ViaBTC's creation guide describes the following steps:

1. Log in to the ViaBTC website and open Watcher Favorites.
2. Select Create a Watcher.
3. Set the permissions and note, then confirm.
4. Complete Google Authenticator or SMS verification.
5. Share the generated link or QR code with the intended recipient.

Anyone who obtains the link can view the information it makes available. Limit distribution to people who need that visibility and review shared links when a technician's assignment or partnership ends.

To stop sharing, manage the Watcher URL you created and revoke it. ViaBTC's Watcher announcement confirms that revocation prevents further viewing through that link. The relevant action is revoking the owner's shared link; do not rely on a recipient removing a saved favorite to end access.

Global Watcher Links and Sub-Account Visibility

A Global Watcher link allows a partner or maintenance team to view data across all of an operator's sub-accounts without permission to change account settings. ViaBTC describes this capability in its account-system upgrade announcement.

This broader scope is useful when a maintenance team supports several sub-accounts. Review whether that team needs visibility across all sub-accounts before sharing a Global Watcher link.

Practical Use Cases

• Hosting-site support: A technician can use shared pool data to investigate a reported interruption without receiving the owner's login credentials.
• Partner reporting: A commercial partner can review the mining information made available through the link.
• Multiple sub-accounts: A maintenance team can use Global Watcher visibility when its responsibilities span the operator's sub-accounts.

Choose the link's scope around the recipient's actual task, and interpret the available performance data within its stated measurement periods.

FAQ

Does a Watcher URL require the recipient to log in?

No. The link provides access to the shared information without an account login. Keep it private because anyone holding it can view that information. Watcher URL documentation

Can a Watcher URL holder change withdrawal addresses?

No. Watcher access does not grant permission to modify the account. App-based alert settings do not change this boundary. Watcher URL documentation

What happens when the owner deletes a Watcher URL?

Others can no longer use that link to view the shared data. ViaBTC explicitly describes this effect in its Watcher launch notice.
