Leave a trace on the Memento Wall.

The Memento Project contains 400 NFTs (20x20). Each NFT has its own and unique coordinates on the Memento grid. Mint a new NFT Tile on project-memento.com. The first mint starts at 0.01 ETH. After each mint the price of the next mint will be multiplied by 1.1, until it reaches the capped value of 2ETH. This means the early buyers will get the cheapest prices.

You'll be able to change the character in it as many times as you want.
