Find a Bitcoin wallet that disappeared after restart
A wallet can be present on disk while its RPC endpoint is unavailable. Two inventories distinguish an unloaded wallet from a missing data directory.
Compare disk and memory
Run both queries against the same node and network. The first lists names found under the configured wallet directory. The second lists the wallets this process has actually loaded.
bitcoin-cli listwalletdir
bitcoin-cli listwallets
Interpret a missing name
If shop appears only in the first result, the directory is visible and you can load that wallet by name. If both lists omit it, verify the selected network, data directory and node identity before attempting recovery. A newly created wallet with the same name would contain different keys.
