Hi.

Silver conductive ink is used to restore continuity in circuits.  The Ag is particulate powder in suspension in a solvent that evaporates... I think.

Is there any chemical solvent that has metal in true chemical reaction solution that when dried/evaporated, its precipitated residue is conductive metal ?

Well I suppose there is the “solvated electron”, formed reversibly by dissolving an alkali metal in liquid ammonia: https://en.wikipedia.org/wiki/Solvated_electron

But that’s definitely in the “don’t try this at home” category.😀
