Dapps are applications powered by Ethereum. See what you can do. ETFs are a basket of assets which can track a particular index, sector, commodity, or other underlying asset, and its shares can be purchased or sold on a national stock exchange. ETFs are able to track the price of their underlying assets because of an arbitrage mechanism which allows market participants to create shares when there is a premium and redeem shares when there is a discount, thus allowing shares of the crypto zoo price fund to trade closely in line with their net asset value. Ethereum allows for the creation of ERC-20 tokens, which can be used as native tokens for the applications that live on the Ethereum blockchain. These tokens can be used for governance on their respective applications, for utility purposes such as paying trading fees, or as stores of value, as in the case of stablecoins like USDT and USDC. However, gas fees for transactions are still paid in ETH, as transactions are still recorded on the Ethereum blockchain.
