What Is Base?

Base is a Layer 2 scaling solution for Ethereum developed by Coinbase. It is built on Optimism's Open Source OP Stack, so just like Optimism it uses optimistic rollup technology. It was launched in the summer of 2023 during what they dubbed to be "onchain summer". It has already gained a lot of usage, and since they are backed by one of the largest cryptocurrency companies, it is likely to continue to grow. The native token of Base is ETH.

What Are Base 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 Base and other blockchain networks, but it can also be dangerous if left unchecked.
