Protocol Level Non-Fungibility

Protocol level non-fungibility refers to design choices in blockchain architectures that intentionally restrict the interchangeability of units. While standard tokens are designed to be identical, certain protocols may incorporate metadata or unique identifiers that distinguish one unit from another at the ledger level.

This can be done for specific utility, such as tracking ownership of real-world assets or enabling complex governance features. When a protocol introduces these distinctions, it inherently breaks the fungibility required for efficient liquid markets.

This creates challenges for derivative pricing models, as the underlying asset is no longer a generic commodity but a specific, non-interchangeable instrument.
