Wagyu

A-

Cross-chain swap — routes through XMR1 on HyperCore, settles to native Monero.

Maintainer: PerpetualCow

⚠ INCIDENT

Incident timeline

  1. 2026-06-19 Operator (@PerpetualCow) last public reply on X on Wagyu-adjacent topics.
  2. 2026-07-06 Third-party outage report (@BerggoldDigital tweet + screenshot): swap widget returns "Failed to fetch" on 0.5 XMR → DAI. Reporter notes operator has gone quiet.
  3. 2026-07-07 Widget partially recovered — /api/rates responds 200 across XMR pairs (DAI/BTC/ETH/SOL/USDC). Two XMR → ETH swaps executed in the last two hours after a 56-day gap in transactions of any kind. But the operator has posted an explicit "Swaps into XMR are temporarily paused" banner on the ANY → XMR direction — the unwind route that would return an XMR1 IOU on HyperCore to native Monero. Grade dropped B- → D on the same day. Operator remains silent on Wagyu channels; publicly active on Hyperliquid memecoin ecosystem.
  4. 2026-07-07 Wagyu widget reported down again by curator ~11:30Z, ~30 minutes after the partial-recovery observation earlier the same morning. Server-side probes: homepage 200, /swap 200, /api/rates 200 — but the /api/rates payload is byte-identical to the earlier 09:30Z probe, suggesting the rate-source is serving a cached/stale response rather than live-fetching. Combined with the operator-declared "Swaps into XMR are temporarily paused" banner on the ANY → XMR path and the 56-day inbound-transaction gap, the service is now fluctuating within a single day AND the "recovered" state was itself misleading. This is the pattern the earlier D-grade was watching for.
  5. 2026-07-07 Operator @PerpetualCow broke silence at 17:40Z on X after 18+ days of no public replies on Wagyu-side topics — first substantive comms since 2026-06-19. Key claims: (a) Wagyu is back live; (b) the downtime was caused by "a massive DDoS attack"; (c) implicit accusation that a competitor orchestrated it. Tone is dismissive of user feedback ("Not even going to bother responding to all the FUD"), boastful about market position ("only 2 sources of XMR: KuCoin and Wagyu; everything else is a wrapper"), and closes with "Going back to my holiday, gn friends." Curator read: the DDoS attribution is unverifiable but plausible, and comms restart IS a positive signal against the "operator vanished" concern. However the post does NOT address the still-live "Swaps into XMR are temporarily paused" banner on the ANY → XMR direction, the intra-day quote-then-fail pattern from earlier today, or the 56-day gap in ANY-inbound transactions — meaning the specific operational issues that drove the D grade are unresolved. The "only 2 sources of XMR" claim is also editorially questionable (ignores DEXes, atomic swaps, direct P2P) and does not match reality of the swap-engine landscape our own listings cover. Grade held at D. Watch conditions unchanged: lift requires resumed ANY → XMR execution + clean curator round-trip test-swap + sustained cadence (not one-off post). Escalation still on the table if the paused-banner is up at the 2026-07-12 re-check.
  6. 2026-07-07 ANY → XMR path is materially back. Widget "Swaps into XMR are temporarily paused" banner has been REMOVED; a DAI → XMR quote renders live (1000 DAI → 2.975812 XMR, ~$1000 → ~$981, matches sane pricing at ~336 DAI/XMR); Swap button enabled. Recent Transactions strip shows FIVE ANY → XMR trades completed in the last 40 minutes (100 DAI → XMR 26m ago, 1 ETH → XMR 26m ago, 0.33 ETH → XMR twice at 34/35m ago, 400 DAI → XMR 40m ago) plus one XMR → ETH at 29m — real bidirectional throughput after ~56 days of one-way-only. Timing lines up with the operator @PerpetualCow going-public post at 17:40Z (~40 min before the earliest of these swaps). Grade held at D for now — this is 40 minutes of data, not a track record — but the operational side of the D case has meaningfully improved. Watch: if ANY → XMR stays open through 2026-07-09 with no re-pause AND a curator round-trip test-swap completes clean, lift to C.
  7. 2026-07-08auto Relative to the on-file state (ANY→XMR paused; operator silent), material recovery signals appeared on 2026-07-07: operator @PerpetualCow claimed Wagyu was back after an unverified DDoS, and @xmr_club reported the pause banner gone with both-direction swaps executing. A third-party post on 2026-07-08 also said the s…

Review

End-to-end the swap delivers native XMR on the Monero chain. Internally Wagyu routes via XMR1 on HyperCore as an intermediary, so the IOU posture only applies if you hold XMR1 (don't). Treat Wagyu as a swap, not a place to park balance: the custodial risk is bounded by how long the IOU is in flight, not the trade size.

Volume itself is real — operator publicly reports ~\$320M cumulative and ~\$30M+ recent monthly, with Wagyu functioning as a genuine XMR throughput rail in the Monero economy.

Operator alignment watch (2026-05-30). Wagyu's founder (@PerpetualCow) is, by his own words, a hype-aligned operator using XMR as instrumentation rather than a privacy-aligned operator with a Monero mission. His X bio reads verbatim: *"$HYPE maximalist. not loud about it, just patient. Contributing to @HyperliquidX and XMR through Wagyu.xyz."* In a separate post on 2026-05-29 he stated: *"Aside from $HYPE there's nothing worth owning in crypto anymore. As sad as it is."* That includes Monero — said publicly by the founder of a Monero swap. Combined with his handling of the $COW community on the adjacent Fwog.fun launchpad (promote → vampire-attack → relaunch → miss deadlines → post-hoc deny leadership → delete community Telegram on 2026-05-18), the pattern reads as textbook hype-maxi behavior.

Wagyu the swap continues to operate normally and the DPRK-pause incident (2026-04-22) was handled credibly. We are not delisting because the product is functional and the volume signals real Monero-economy demand. But: don't park balance, don't size larger than you'd be willing to absorb if the operator decides to walk, and weight the alignment mismatch in your trust posture. Grade adjusted B → B- to reflect the structural alignment mismatch. Further movement depends on Wagyu-side stress events.

2026-07-07 caveat — do not initiate new swaps. Operator's last public reply on X was 2026-06-19 (18 days silent as of this note). As of 2026-07-07 the swap widget quotes both directions but displays an *"Swaps into XMR are temporarily paused"* banner on the ANY → XMR path — the unwind that would take an XMR1 IOU on HyperCore back to native Monero on the Monero chain. That is the entire "settles to native Monero" thesis this listing was graded on. Only the XMR → ETH direction has completed swaps in the last two hours (two of them, after a 56-day gap in transactions of any kind). Operator (@PerpetualCow) is publicly active on the Hyperliquid memecoin ecosystem in the same window; only surviving official support channel is `t.me/wagyu_support`. Grade dropped B- → D. Do not initiate new swaps in either direction: the ANY → XMR side is operator-paused, and the XMR → ETH side traps users into a stuck XMR1 balance they cannot currently unwind. No evidence of fraud; the D reflects a self-declared one-way service that is not functioning as advertised. Grade lifts back only after the "temporarily paused" banner is gone AND a curator round-trip test-swap completes end-to-end AND operator resumes public cadence.
