Trade Surplus occurs when a trade executes more favorably than originally quoted.

For example, if you were quoted to receive 100 tokens, but market conditions improve before the trade finalizes, you might actually receive 102 tokens. That extra 2-token difference is the “surplus” that results when the trade outcome exceeds expectations.

If there’s a positive difference in trade execution, Matcha keeps the surplus — a common practice across aggregators. You will never receive less than what you expect from the quote and slippage settings.

Trade Surplus is enabled for all market orders on Matcha, which includes Matcha Auto and Matcha Standard trades. You will never receive less than what you expect from the quote and slippage settings.

This does not apply for Limit Orders and Cross Chain trades.
