NAME

Bitcoin::RPC::Client - Bitcoin Core JSON RPC Client

SYNOPSIS

   use Bitcoin::RPC::Client;

   # Create Bitcoin::RPC::Client object
   $btc = Bitcoin::RPC::Client->new(
      user     => "username",
      password => "p4ssword",
      host     => "127.0.0.1",
   );

   # Check the block height of bitcoin node
   #     https://developer.bitcoin.org/reference/rpc/getblockchaininfo.html
   $chaininfo = $btc->getblockchaininfo;
   $blocks = $chaininfo->{blocks};

   # Estimate a reasonable transaction fee
   #     https://developer.bitcoin.org/reference/rpc/estimatesmartfee.html
   $fee = $btc->estimatesmartfee(6);
   $feerate = $fee->{feerate};

   # Set the transaction fee
   #     https://developer.bitcoin.org/reference/rpc/settxfee.html
   $settx = $btc->settxfee($feerate);

   # Check balance
   # (JSON::Boolean objects must be passed as boolean parameters)
   #     https://developer.bitcoin.org/reference/rpc/getbalance.html
   $balance = $btc->getbalance("*", 1, JSON::true);

   # Send to an address
   #     https://developer.bitcoin.org/reference/rpc/sendtoaddress.html
   $transid = $btc->sendtoaddress("1DopyzQi9mX3huvGacfjpzCKFug2Dtvykp","0.01");

DESCRIPTION

This module implements in Perl the functions that are currently part of the Bitcoin Core RPC client calls (bitcoin-cli).The function names and parameters are identical between the Bitcoin Core API and this module. This is done for consistency so that a developer only has to reference one manual: https://bitcoin.org/en/developer-reference#remote-procedure-calls-rpcs

CONSTRUCTOR

$btc = Bitcoin::RPC::Client->new( %options )

This method creates a new Bitcoin::RPC::Client and returns it.

   Key                 Default
   -----------         -----------
   host                undef (Required)
   user                undef (Required)
   password            undef (Required)
   cookie              undef
   port                8332
   wallet              undef
   timeout             20
   ssl                 0
   verify_hostname     1
   debug               0
   syntax              0

cookie - Absolute path to your RPC cookie file (.cookie). When cookie is defined user and password will be ignored and the contents of cookie will be used instead.

wallet - Work against specific wallet.dat file when Multi-wallet support is enabled (Bitcoin Core v0.15+ only)

timeout - Set the timeout in seconds for individual RPC requests. Increase this for slow bitcoind instances.

ssl - OpenSSL support has been removed from the Bitcoin Core project as of v0.12.0. However Bitcoin::RPC::Client will work over SSL with earlier versions or with a reverse web proxy such as nginx.

verify_hostname - Disable SSL certificate verification. Needed when bitcoind is fronted by a proxy or when using a self-signed certificate.

debug - Turns on raw HTTP request/response output from LWP::UserAgent.

syntax - Removed as of Bitcoin::RPC::Client v0.7, however having the value set will not break anything.
