Linear

With a linear bonding curve, the price of an NFT is increased by a flat amount (called delta) every time an item is bought from the pool. Conversely, the price of the NFT is decreased by that same flat amount every time an item is sold to the pool.

For example, a liquidity provider may create an NFT<>SMR pool with a Start Price of 1 SMR and a delta of 0.1 SMR. Assuming enough liquidity, the price of an NFT will increase to 1.1 SMR after one item is purchased from the pool. After a second item is purchased, the price will increase to 1.2 SMR.. At any point, if an NFT is sold to the pool, the price will decrease by 0.1 SMR.
