validateaddress (wallet fields)
util removed deprecated v0.18 removed v0.18
This RPC no longer exists in Bitcoin Core.
Documented here so users finding old tutorials, blog posts, or code samples
can learn what it did, when it went away, and what to use instead.
The wallet-related fields of validateaddress (ismine, iswatchonly, etc.) were split into getaddressinfo. validateaddress itself still exists but only validates address structure.
Use instead
Last-known help text
From the version just before removal.
Pre-0.18, validateaddress returned wallet-aware fields like 'ismine'.
These were moved to a new RPC: getaddressinfo. validateaddress now only
checks whether an address is structurally valid (no wallet lookup).
