What is bridging strategy?

Could you please elaborate on the concept of bridging strategy in the realm of cryptocurrency and finance? I'm particularly interested in understanding how it works, its benefits, and potential risks associated with its implementation. Could you also provide some examples of bridging strategies in action, perhaps highlighting successful cases as well as any challenges encountered? Finally, what factors should be considered when devising a bridging strategy, and how does it fit into the broader landscape of cryptocurrency and financial markets?
