TezosClient

Tezos Client interacts with Tezos nodes using RPC commands.

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

michelson-to-micheline

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

SmartPy

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

TypeScript (for dev)

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"
#    }

Transfer funds

client = TezosClient.new

client.transfer(
    amount: 1,
    from: "tz1ZWiiPXowuhN1UqNGVTrgNyf5tdxp4XUUq",
    to: "tz1ZWiiPXowuhN1UqNGVTrgNyf5tdxp4XUUq",
    secret_key: "edsk4EcqupPmaebat5mP57ZQ3zo8NDkwv8vQmafdYZyeXxrSc72pjN"
  )

Call a contract

client = TezosClient.new
client.transfer(
    amount: 5,
    from: "tz1ZWiiPXowuhN1UqNGVTrgNyf5tdxp4XUUq",
    to: "KT1MZTrMDPB42P9yvjf7Cy8Lkjxjj4jetbCt",
    secret_key: "edsk4EcqupPmaebat5mP57ZQ3zo8NDkwv8vQmafdYZyeXxrSc72pjN",
    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(
  from: "tz1ZWiiPXowuhN1UqNGVTrgNyf5tdxp4XUUq",
  secret_key: "edsk4EcqupPmaebat5mP57ZQ3zo8NDkwv8vQmafdYZyeXxrSc72pjN",
  to: "KT1STzq9p2tfW3K4RdoM9iYd1htJ4QcJ8Njs",
  amount: 0,
  entrypoint: "myEntryPoint",
  params: { int: 1 },
  params_type: :micheline
)
