When I was in college, I brought a coil to the chemistry department and
talked to some of the professors about silver plating it. The one who knew
the most about it explained that it required silver cyanide, and indicated
that he wasn't going to fool with it!

I know cyanide is used in gold plate solution but not aware of it

It seems that silver chloride is the main ingredient.
Silver chloride is used in ion exchange, or flash plating. It may be used
in electroplating, but I never used it in electroplating.
Silver cyanide is used in smooth electroplating, (electronic and
decorative) the most common form of plating..
Silver Nitrate is also used in electroplating, but produces a rough,
crystalline surface and is only used in industry AFAIK.
Cyanide solutions are dangerous! Extremely dangerous. It only takes a
drop of something acetic to release cyanide gas which is odorless and
colorless. Observe all safety precautions in the MSDS for the chemicals
used and use in a properly ventilated area. I did all my work in a fume
hood.
I did all the silver plating for the company I worked for in the early
days, a good 50 years ago.
