## API Stability

API stability refers to the commitment of developers to keep the interface for interacting with a protocol consistent over time. For developers building applications on top of a blockchain, such as decentralized exchanges or wallet interfaces, frequent breaking changes are highly disruptive.

Stability allows for the creation of reliable infrastructure and user-facing tools. It requires a rigorous process of testing and backward compatibility for all public-facing endpoints.

Maintaining this stability is a balancing act between supporting innovation and preventing application failure. It is a key factor in the long-term adoption of a protocol.
