Ethereum and Gas the coin of smart contracts

Ethereum is essential to the world of Smart Contracts.  Most smart contracts with big names are on the Ethereum chain and use ERC-20 tokens.  There are lots of projects like Compound and Aave where you can earn a lot of interest by lending out your ERC-20 tokens.  You put your coins into a smart contract and receive interest.  You can also convert Ether in to popular tokens like Uniswap and Sushiswap and keep them in your Ethereum wallet.  Wallet by Coinbase is one of our favorite Ethereum wallets, especially if you trade on the Coinbase platform.
