walletlock - Bitcoin RPC

walletlock

Removes the wallet encryption key from memory, locking the wallet.
After calling this method, you will need to call walletpassphrase again
before being able to call any methods which require the wallet to be unlocked.

Examples:

Set the passphrase for 2 minutes to perform a transaction
> bitcoin-cli walletpassphrase "my pass phrase" 120

Perform a send (requires passphrase set)
> bitcoin-cli sendtoaddress "1M72Sfpbz1BPpXFHz9m3CdqATR44Jvaydd" 1.0

Clear the passphrase since we are done before 2 minutes is up
> bitcoin-cli walletlock 

As json rpc call
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "walletlock", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/

          

This is a website, created out of frustration with uncomplete and outdated Bitcoin Core RPC documentation online.

It was inspired by ChainQuery, which seems to be abandoned. These docs are even simplier, so they can be regenerated by anyone.

Made by @karel_3d; license of the docs is MIT (see bitcoin repo), license of the scripts and webpage is also MIT ((C) 2018 Karel Bilek) (github repo)

Bitcoin version: 0.16.0.

Note that the RPC is from a regtest node (for completeness), so it includes some additional calls that a regular node doesn't have.
