Arc risk pulse

One signed row per UTC day, computed from what the CompliR tailer observed and what clients asked us to screen. Open data for analysts: JSON per day, a flat CSV, and an attester signature over every row.

Sample = what the CompliR tailer observed in its block windows and what clients asked us to screen; it is not all of Arc.
Volume is the USDC moved on Transfer edges the tailer persisted that day (graded nodes and their counterparties); flagged = HIGH tier or a blocklist reason code at the time of computation.
Tailer ticks count distinct tick timestamps that wrote rows; quiet ticks (no USDC activity in the window) are not counted.
No CCTP inbound table on this deployment; bridged figures are zero and marked unavailable.
Flagged = HIGH tier or a blocklist reason code (sanctions, USDC blacklist, protocol blocklist) at the time the row was computed; a later regrade changes later rows, not this one.
Own wallets and internal client ids are excluded from the outside-payer counts; screenings they triggered are counted as internal.

How to verify

Fetch the day, hash the stats object exactly as we do (sorted keys, no whitespace), and check the signature against the attester address.

import { keccak256, stringToHex, verifyMessage } from "viem";
const r = await (await fetch("/api/v1/stats/2026-10-12.json")).json();
const canon = (v) => Array.isArray(v) ? "[" + v.map(canon).join(",") + "]"
  : v && typeof v === "object" ? "{" + Object.keys(v).sort().map(k => JSON.stringify(k) + ":" + canon(v[k])).join(",") + "}"
  : JSON.stringify(v);
const hash = keccak256(stringToHex(canon(r.stats)));   // === r.hash
await verifyMessage({ address: r.signer, message: hash, signature: r.signature }); // true
