What does a ASD stand for?

Excuse me, could you kindly clarify what ASD stands for in the context that you're referring to? I'm familiar with a few different meanings for ASD, ranging from Autism Spectrum Disorder in medical terminology to Anti-Submarine Defense in military jargon. However, in the realm of cryptocurrency and finance, it's not a widely recognized acronym that immediately springs to mind. Could you perhaps provide some additional context or elaborate on what ASD specifically pertains to in this field? It would greatly assist in providing an accurate and relevant explanation.
