What Is Harmony?

Harmony is a Layer 1 blockchain with a consensus mechanism based on Proof of Stake. It is focused on providing fast and low-cost transactions by applying state sharding, a technique that essentially splits up the entire state and validation of the network into multiple sub-blockchains. The native token of Harmony is ONE. Learn more about Harmony on its website.

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