These values are DAO-controlled parameters, and designed to make Quick Lane economically self-sustaining.

BNT burning from Quick Lane could be tracked by way of the Bancor Alerts Telegram or within the “onchain-events” channel of the Bancor Discord, with extra neighborhood analytics instruments anticipated quickly. A latest instance of a Quick Lane arbitrage transaction could be discovered right here, exhibiting 185 BNT being burned and the utmost of 100 BNT paid to the caller.
