What Is BOB?

BOB (Build-On-Bitcoin) is a Layer 2 scaling solution powered by both Bitcoin and Ethereum. BOB is built using the open source OP Stack from Optimism, which means that it uses optimistic rollup technology. It currently uses Ethereum as its data availability Layer, but plans to use Bitcoin for data availability and merged mining in the future. The native token of BOB is ETH.

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