importprivkey

importprivkey “privkey” ( “label” ) ( rescan )

Adds a private key (as returned by dumpprivkey) to your wallet. Requires a new wallet backup.

Arguments:

“privkey” (string, required) The private key (see dumpprivkey)
“label” (string, optional, default="") An optional label
rescan (boolean, optional, default=true) Rescan the wallet for transactions

Note: This call can take minutes to complete if rescan is true, during that time, other rpc calls may report that the imported key exists but related transactions are still missing, leading to temporarily incorrect/bogus balances and unspent outputs until rescan completes.

Examples:

Dump a private key

bitcoin-cli dumpprivkey “myaddress”

Import the private key with rescan

bitcoin-cli importprivkey “mykey”

Import using a label and without rescan

bitcoin-cli importprivkey “mykey” “testing” false

Import using default blank label and without rescan

bitcoin-cli importprivkey “mykey” "" false
