Where is the yield set?

I'm curious, could you please elaborate on the question, 'Where is the yield set?'. Are you referring to the yield of a specific cryptocurrency investment, or perhaps a financial instrument like a bond or savings account? In the world of finance and cryptocurrency, yields can be set in a variety of places depending on the product. For example, if we're talking about a cryptocurrency staking program, the yield is typically set by the protocol or platform offering the staking service. On the other hand, if it's a traditional investment like a bond, the yield is often determined by the market and the creditworthiness of the issuer. Clarifying the context would help me provide a more accurate and informative response.
