Requirements

Tezos client requires SmartPy to be installed in order to work properly. To install it on Linux, you can basically follow the steps coded in travis-script folder.

Dependency

sudo apt-get install nodejs
npm i -g michelson-to-micheline

SmartPy

SmartPy

sh <(curl -s https://smartpy.io/releases/20210317-bc925bb73dc885ac2b4dde9689e805d9b0bc6125/cli/install.sh)
export PATH=$PATH:$HOME/smartpy-cli/

npm install -g typescript

Installation

Add this line to your application's Gemfile:

gem "tezos_client"

And then execute:

$ bundle

Or install it yourself as:

$ gem install tezos_client

Usage

Generate Tezos key pairs

Generate a perfectly random key pair:

client = TezosClient.new
key = subject.generate_key
          expect(key[:address]).to eq "tz1RfnzRopJXH32SSDap2wMYGULBAnmHxdP1"
# => {
#       secret_key: "edsk4T2fHv5RLL3VSXHz82SQiyFx7vZ4wwtA2u67AvAaw5yqNEvuU2",
#       public_key: "edpkuncp7KSVhV57Qg7odwhMFcnAHnNrMppbitBPKBfvdg6fFVeNjr",
#       address: "tz1a97x7GAvMDyrwwKTLQo131CoidXyUef48"
#    }

Generate a key pair from a seed and a BIP 44 Path:

key = subject.generate_key(wallet_seed: "000102030405060708090a0b0c0d0e0f", path: "m/44'/1729'/0'/0'/0'")
          expect(key[:address]).to eq "tz1RfnzRopJXH32SSDap2wMYGULBAnmHxdP1"
# => {
#       secret_key: "edsk4T2fHv5RLL3VSXHz82SQiyFx7vZ4wwtA2u67AvAaw5yqNEvuU2",
#       public_key: "edpkuncp7KSVhV57Qg7odwhMFcnAHnNrMppbitBPKBfvdg6fFVeNjr",
#       address: "tz1a97x7GAvMDyrwwKTLQo131CoidXyUef48"
#    }

Generate a key pair from a BIP-39 mnemonic sentence and a BIP 44 Path:

key = subject.generate_key(
          mnemonic: "below dove cushion divide future artefact orange congress maple fiscal flower enable",
          path: "m/44'/1729'/0'/0'/0'")
          expect(key[:address]).to eq "tz1RfnzRopJXH32SSDap2wMYGULBAnmHxdP1"
# => {
#       secret_key: "edsk4T2fHv5RLL3VSXHz82SQiyFx7vZ4wwtA2u67AvAaw5yqNEvuU2",
#       public_key: "edpkuncp7KSVhV57Qg7odwhMFcnAHnNrMppbitBPKBfvdg6fFVeNjr",
#       address: "tz1a97x7GAvMDyrwwKTLQo131CoidXyUef48"
#    }

    parameters: '"pro"'
  )

Originate a contract written in SmartPy

script = File.expand_path("./spec/fixtures/demo.py")
source = "tz1ZWiiPXowuhN1UqNGVTrgNyf5tdxp4XUUq"
secret_key = "edsk4EcqupPmaebat5mP57ZQ3zo8NDkwv8vQmafdYZyeXxrSc72pjN"
amount = 0
init_params = "MyContract()"
client = TezosClient.new

res = client.originate_contract(
    from: source,
    amount: amount,
    script: script,
    secret_key: secret_key,
    init_params: init_params
  )

puts "Origination operation: #{res[:operation_id]}"
puts "Contract address: #{res[:originated_contract]}"

Call a contract written in SmartPy

TezosClient.new.call_contract(
