Protocol-level wash trade prevention: expire maker on same-account match
Self-Trade Prevention
SB Chain prevents wash trading at the protocol level. When an incoming order would match a resting order from the same account, the resting order is cancelled rather than filled. No fee is charged and the cancellation does not appear in the public trade feed, equivalent to "expire maker" on centralised exchanges. Market making bots benefit directly: quotes can be updated aggressively without risk of trading against themselves.
