This package provides a guzzle driver for the nbobtc/bitcoind-php RPC interface.
It's a small package, but allows you to make use of the Guzzle client instead of maintaining the same configuration in terms of curl options.
This package has a dependency on nbobtc/bitcoind-php, so installing the driver will also install the package. Presently it will work alongside 2.0|2.1, but this can be expanded as required (just open an issue).
composer require bit-wasp/bitcoind-php-guzzle
