xStocks Three-Chain Inventory-Hedged Arbitrage is a live trading strategy combining on-chain stock-token inventories with Binance perpetual contracts. It accesses Robinhood, X Layer and Solana through OKX DEX, uses Binance perpetual shorts to hedge inventory price exposure, and targets inter-chain spreads and deviations in the on-chain versus perpetual basis.

The strategy continuously compares executable quotes across venues and rechecks fees, gas and slippage costs before placing paired trades. Inter-chain trading supports both absolute-spread and mean-reversion modes. Trades involving Binance are evaluated against the long-term basis to avoid treating a persistent premium as an arbitrage opportunity.

Key features:
• Three-chain inventory management: Monitors stock-token and stablecoin balances and redistributes inventory through trades, without requiring a cross-chain transfer for every arbitrage trade.
• Perpetual hedge maintenance: Reconciles the share-equivalent on-chain inventory with Binance short positions and adjusts the hedge when the configured conditions are met.
• Execution reconciliation and recovery: Persists order groups and verifies execution using on-chain receipts, balance changes and futures positions. Uncertain outcomes or partial fills block new trades; after a restart, existing orders are reconciled first.
• Cost and risk controls: Includes quote revalidation, pool round-trip cost limits, leverage limits and a shutdown threshold for cumulative realized net losses from settled order groups.
• P&L attribution: Separately reports realized arbitrage P&L, hedge and liquidation execution costs, and floating changes attributable to prices, basis, funding and other factors.

The current version supports only the whitelisted GOOGLx and AMZNx tokens across the fixed Robinhood, X Layer and Solana combination. Add OKX DEX as the first exchange and Binance Futures as the second. Prepare the required token inventories, stablecoins, gas balances and corresponding Binance perpetual hedges before starting. Failed startup checks stop execution; the strategy does not automatically establish initial inventories or hedge positions.

This strategy is live-only and does not support backtesting. Inventory hedging aims to reduce directional price exposure; it does not eliminate risk or guarantee profits. Basis changes, funding costs, slippage, on-chain delays and mismatched execution between trade legs remain relevant risks.
