Etholvants are 100% on-chain generated, deflationary and evolving creatures living on the Ethereum blockchain.
Rules are simple. There are 10,000 unique etholvants available to mint at a price of 0.024 ETH each. They will be born with 24 cells initially and they can evolve by either staking or combining.
If you stake an etholvant into the contract, it will grow by 2 cells in every 4 hours. So if you stake one with 24 cells, after one day it will have 36 cells.
If you combine multiple etholvants, they will be burnt and a new one will be created. Its number of cells will be equal to the sum of the number of cells of the burnt ones. So if you combine two etholvants with 24 cells and 40 cells, you’ll get one with 64 cells.
Combining and staking are free (only gas fees) and unstaking has a fee of 0.01 ETH per transaction (you can unstake multiple tokens in each transaction). The size of the art will also increase as the etholvant evolves.
Everything is on-chain, including the art, which you can get the positions of the cells from the contract. Etholvants are standard ERC721 tokens so you can buy and sell them on OpenSea.
