Optimism is one of the most popular Layer 2's for Ethereum. Besides the main Optimism network, Optimism also develops a technology stack that can be used by other L2's such as the Base network by Coinbase. The native token of Optimism is ETH.

What Are Optimism Token Approvals?
Token approvals are used to give permission to a smart contract to spend your tokens on your behalf. This is a common pattern used by decentralized exchanges and other decentralized applications. This is an important feature for the functioning of decentralized applications on Optimism and other blockchain networks, but it can also be dangerous if left unchecked.
