What is a crypto anchor?

Could you please elaborate on the concept of a "crypto anchor" in the realm of cryptocurrency and finance? I'm curious to understand how it functions within the broader ecosystem and what role it plays in ensuring stability or facilitating transactions. Is it a technical mechanism, a type of asset, or a conceptual framework? I'm particularly interested in how it relates to other components of the cryptocurrency landscape, such as blockchains, decentralized finance, and smart contracts. Thank you for your insight.
