Each trader's full transaction history on BSC and ETH was scraped from BscScan and Etherscan (Etherscan MCP API lacks BSC coverage and was unavailable on ETH this session). Cycles were reconstructed by matching bridge deposit → withdraw 1:1 by exact VOW amount (DBridge burn-and-mint, verified to the wei) plus tight timestamp proximity, then walking forward/backward to find the funding, DEX buy, DEX sell, and USDT return legs.
P&L definition: gross USDT (sell out − buy in) per matched cycle. Excludes gas, bridge relayer tips (0.0003 ETH / 0.001 BNB per withdraw), and DEX slippage (slippage is already embedded in swap output). Where a sell routed USDT off-wallet via an aggregator router, the USDT-out is an Etherscan price-quote estimate — flagged in-line. No number is fabricated; missing legs are marked.
