What Is zkSync Era?

zkSync Era is a Layer 2 scaling solution and one of the first projects to use the novel zkEVM technology. This technology offers very low fees while maintaining strong security guarantees through the use of zero-knowledge proofs. zkSync previously created zkSync Lite, which was an early version of zkRollup technology that was not yet EVM compatible. zkSync Era is the next iteration, adding full EVM support. The native token of zkSync Era is ETH. Learn more about zkSync Era on its website.

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