What is Chain Migration?

A chain migration occurs when a blockchain project decides to operate on a different blockchain protocol. At this time, most decentralized finance (DeFi) projects are built on the Ethereum blockchain. An example of a chain migration would be a DeFi protocol on the Ethereum blockchain migrating — complete with all its product and service offerings — over to the BNB Smart Chain. Chain migrations occur for various reasons such as moving to a chain with lower fees or better throughput, changes in company direction, or desired changes in tokenization standards (e.g., from ERC-20 to BEP-20).
