Spreader opens without registration. The first visit creates a guest session in your browser, and the scanner starts streaming right away. Sign up when you want more saved pages, favorites, alerts or trading.

​
First visit as a guest

Spreader scanner for a guest: table of spreads, sidebar with locked Positions, Alerts and Settings

The scanner as a guest sees it. Sections with a lock need an account.

A guest gets the full live scanner with filters, views and columns. The limits below apply until you sign up. When the service is under heavy load, guests are slowed to one update per second first. Signed in users keep full speed.

​
Sign up or log in

Sign up form with Username and Password fields and a Sign up button

The sign up form. The Log in form asks for the same two fields.

  1. Click the log in icon at the right end of the header.
  2. On the login page choose Sign up under the form.
  3. Enter a username (2 to 40 characters: a to z, digits, dot, dash, underscore) and a password of at least 8 characters.
  4. Click Sign up. You are signed in immediately.
Your guest pages are not carried over. Save the filters you care about again on the new account.

The layout

Spreader header with search box, live indicator, language flag, theme toggle and account menu

Header: sidebar toggle, breadcrumb, search, connection state, language, theme, account.

  • Sidebar on the left lists your scanner pages, Tools and Settings. The first header button hides or shows it.
  • Search (Ctrl K or Cmd K) finds an asset, an exchange, a pair or one of your pages. Paste a contract address to search by contract.
  • Connection state shows live with the current delay, reconnecting when the stream is interrupted and no fresh quotes when exchanges stop answering.
  • Language switches the interface between English, Russian and Ukrainian.
  • Theme toggles dark and light mode. Both are remembered in the browser.
  • Account menu shows your username and Log out. A guest sees a log in icon instead.
Sidebar with Scanners list, Tools section and Settings section
