Architecture and Incentive Risks of Crypto Self-Matching Strategies

Summary

The document distinguishes conventional market making, which seeks spread income by quoting different bid and ask prices, from a volume-boosting self-matching approach. In the latter, buy and sell orders are posted at the same price to generate trading volume, with potential returns dependent on exchange rebates, fee tiers, or incentive programs rather than price differences. It outlines a two-layer software design: an exchange interface layer handles market data, account details, and order status, while a strategy layer manages orders and tracks fills. The included example is presented as an educational framework, not a validated live system.

The article identifies key dependencies and hazards: transaction costs can exceed rewards, exchange incentive terms can change, and some venues prohibit artificial volume or wash trading. It provides no demonstrated profitability or live trading evidence, and explicitly says the code has not been tested in live markets. The source is also incomplete in the supplied text, so important implementation details cannot be evaluated. Any assessment would need to account for exchange rules, fee schedules, order behavior, and jurisdictional constraints.

Key ideas

• Same-price buy and sell orders aim to accumulate volume rather than capture a bid-ask spread.
• Potential returns depend on exchange rebates, fee discounts, or other volume-linked incentives.
• The described architecture separates exchange API handling from strategy order management.
• Fees, changing incentive terms, and exchange restrictions can make the approach unprofitable or impermissible.
• The example is educational, lacks live validation, and is incomplete in the supplied text.
