XPR ChainWatch

What you can do here

Overview shows live chain activity and a playground where you can assemble a check.
Contracts lists the market contracts in the public catalogue.
Findings are published pattern matches with evidence. A match means a configured pattern fired, not that someone intended wrongdoing.
Build a check by connecting blocks from Chain to Signal. Each block sees the whole transaction. On Signal choose Once (every match), Burst (N matches from the same sender in 5, 15, or 30 minutes), or Ping-pong (N reversals in 10, 15, or 30 minutes across every transaction the flow matches). Play tests that window against recent transactions in this browser only and stops after 200 matches. Start back test sends one historical transaction through the same flow as a red marker; it never creates a published finding and does not open Details. Submit sends the idea for review.
Suggested checks are visitor-submitted playground graphs waiting for review. They are not live checks. Open a suggestion and choose Open in playground to copy the graph into your own editor, then Play or submit it as a new suggestion.
Methodology describes the published checks and the conditions they evaluate.
My watches stores playground flows on a WebAuth wallet. Matches go only as a Telegram direct message to you. They are not published findings and do not use Platform Telegram channels.

How to read a finding

Each finding names the pattern, the accounts and markets involved, and the supporting transactions grouped by transaction id. Burst findings name the sender and how many matching transactions landed in that aligned window. Ping-pong findings show the path and reversal count.
Severity and confidence are scores for the match, not a verdict about a person.
Open a finding for the evidence timeline and a link to the XPR explorer.
Head, indexed, and last irreversible block on Overview show how fresh the public data is.

Playground

On a phone, drag a palette block onto the canvas without waiting, or double-tap it to insert the block. Check, Filter, and Logic stack. Scroll the page from empty space or headings; dragging a palette block does not scroll the page. Hold a canvas block to move it, drag empty canvas to pan the whole view, and pinch to zoom. Chain sits at the top, Signal at the bottom. Arrange and Reset flow share the same layout.
On a larger screen, drag a block from the left list onto the canvas, or double-click it to insert. Keyboard Enter still inserts a block. Blocks are grouped under Check, Filter, and Logic. Hold a canvas block to lift and move it. Drag empty canvas to pan, including while zoomed. Drag from a green handle to another handle to wire blocks. Click a wire to select it, then drag either end to a valid handle to reattach it. Arrange lines the flow up left to right. New flow asks whether to save the current graph to My watches, then returns to Chain and Signal only. Reset flow clears the canvas immediately without that prompt. Green particles are live chain activity, not the wire.
Play shows Starting immediately, then Watching once the session is ready. Once fires on every matching transaction. Burst fires when the same sender reaches the match count in the aligned window and lists those member transactions. Ping-pong fires when the match path reverses N times and lists the path plus member transactions; add Account, Token, NFT, Market, Contract, or Staking filters or unrelated wallets mix. A session stops after 200 matches. Matches stay here and are not published findings.
Start back test takes a transaction id or an XPR explorer transaction URL and sends that one transaction through the flow as a red marker. Blocks show Passed or Blocked. Signal shows Signal generated when the transaction reaches it. Details stays closed until you open it; the list marks the row as Backtest. It never creates a published finding.
Submit only if you want reviewers to consider the idea. Reviewers decide whether it becomes a check. Opening someone else's suggestion copies the graph locally; an identical resubmit within 24 hours is treated as a duplicate.
Save watch stores the compiled flow for your wallet. Link Telegram from My watches so matches can arrive as a private direct message. Play and Save never publish a finding.
