On Chain Check Gas is a 100% on-chain Open Edition NFT that visualizes the current gas price.
On Chain Gas holders can claim 1 free token per On Chain Gas token.
Most NFTs are stored on a centralized server, which means that the when the token is loaded, the metadata is fetched from the server. This is not the case with On Chain Check Gas. The metadata is stored on the blockchain, which means that the token can be loaded without any additional requests. In addition, the metadata contains a fully functioning webpage, which is injected into the token. The visualizer you see is the webpage that is stored on the blockchain.
There are two on-chain representations provided. One is the animated gas visualizer you see here. The other is the static image that is typically shown is list views. The static image is randomly generated at mint time and shows the price of gas when the token was minted as well as a random field of checks. The higher gas when minted, the higher chance of spawning more checks.
When the token is loaded, the current gas price is injected into the visualizer. There is an option for live updates, which will make a connection to a web3 RPC for additional updates after the first load. This RPC is currently provided by infura, but can be updated in the future to any other RPC provider by the contract owner.
Onchain Check Gas NFT has a royalty of 0% on secondary sales.
