Onchain Gas is a 100% on-chain NFT that visualizes the current gas price.

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 Onchain 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.

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 Gas NFT has a royalty of 0% on secondary sales.
