wagyu.xyz runs two rigged systems, both proven by the evidence: 1. Rigged coinflip. The site advertises "48% win chance, 4% house edge" (coinflip-public-claim.txt, coinflip-public-terms.json), but server settings aimed for a 4.00% expected edge and the distribution of outcomes is measurably shifted against players: of 2,852 provably-fair-verified flips, 1,417 fell in the 0-48000 band versus 1,325 above 52000, with only 110 in the dead zone (coinflip-measured-odds.json, result_bins). The provably-fair HMAC checks all pass (coinflip-fairness-verify.py, coinflip-sample-seed-chain.json), which only proves the commits weren't tampered per-round; the win thresholds themselves are crooked. Internal accounting confirms: expectedEdge "4.00", actualEdge "2.92" against a published 2% edge, and a 36.49% player win rate (coinflip-house-stats.json, coinflip-settings.json, coinflip-accepted-orders.json). 2. Hidden fee overcharging. Across 28,840 swap/bridge orders totaling ~$264.9M notional, wagyu advertised $1.73M in fees but actually collected $5.64M, hiding $3.9M or 69.28% of its real take (fee-overcharge-metrics.json). 13,190 orders were charged above the quoted rate, 1,812 above 2 percentage points. The server's internal policy charges up to 10% where the public disclosure says 2% (fee-policy-server.json vs fee-public-disclosure.txt, fee-policy-feeds.json, fee-overcharge-summary.json). Worst cases are itemized in fee-top100-overcharged.csv, e.g. order RMNCMB: $3.17M swap, quoted 0.02, charged 0.08, $190,092 stolen (fee-order-RMNCMB.json). Evidence to support this can be found below:
