Verified swaps are swaps decoded directly from the chain in pools that passed verification; findings describe the verified pools that were measured, never a token's whole market, and none is an accusation.

What an Evidence Card for DIEM contains

Every anomaly finding comes with an Evidence Card that answers five questions, built only from stored data. A value that cannot be determined is shown as unknown, with the reason.

  1. What was observed? The metric and its unit, the observed value against the expected baseline, and the window in UTC.
  2. Where is the evidence? Network, chain id and the token's contract; the block range; each measured pool with its protocol and decoder family; the swap count and the five largest transactions; the RPC providers and ingestion runs covering the window.
  3. How was it computed? The method and its version, the baseline window and value (frozen when the anomaly starts), the parameters and the detector's facts.
  4. How much can we trust it? Hours expected against hours fully covered, every gap, the checks that passed, and the caveats and alternative explanations.
  5. How can it be checked independently? The detection SQL with its SHA-256, and a recipe for any public JSON-RPC node that needs no access to our database.

Check it on a public node

The reproduction recipe re-reads the same swap logs from any public JSON-RPC endpoint:

// eth_getLogs over the measured pools, one Swap topic per decoder family
{"method": "eth_getLogs", "params": [{
  "address":   ["<measured pools>"],
  "topics":    ["<Swap event topic>"],
  "fromBlock": "<first block, hex>",
  "toBlock":   "<last block, hex>"
}]}

The pool list, the exact block range and the expected swap count for each finding are in the Evidence Snapshot and in the application.
