Burns

Auto-Burn tokens destroy a share of every trade. On a bonding curve token that happens on the curve and, after graduation, by buying tokens back from the pool and burning them. On an instant token the fee is collected in the currency it trades against and used to buy the token back and burn it, and a holder rewards tax can add to that. Supply only ever goes down. Every figure here is indexed from the chain.

Burns are real burn() calls: total supply falls on-chain, and you can check every one on the explorer. See where the rest of the fee goes on Fees & burns.
