Zeus Getting Started¶

Overview¶

Zeus-cmd is an extensible command line tool. SDK extensions come packaged in “boxes” and are served through IPFS. Zeus is currently in alpha.

Features:¶

Smart contract templating with a single command
Install nodeos, keosd, cleos, and eosio.cdt with a single command
Simulate a blockchain node with a single command
Test, compile, and deploy smart contracts
Easily migrate a contract to a different EOSIO chain such as the Kylin and Jungle testnets or the mainnet
Design fluid dApp frontends
Cross-platform (Windows, OS X, Linux)
Easily install necessary libraries with a package manager
Truffle-like interface
Manage development lifecycle with version control
Open source (BSD License)
And more…

Hardware Requirements¶

16GB RAM
2 CPU Cores

Prerequisites¶

nodejs == 10.x (nvm recommended, install at bottom of doc)
curl
cmake
make

Recommended eosio.cdt and eosio versions¶

Automatically installed with zeus unbox helloworld

Install Zeus¶

npm install -g @liquidapps/zeus-cmd

Update¶

npm update -g @liquidapps/zeus-cmd

Test¶

zeus unbox helloworld
cd helloworld
zeus test

Try out a game!¶

LiquidApps’ take on Elemental Battles: https://cardgame1112.dnsregistry1.com/ | code

The game incorporates:

vRAM - light-weight caching solution for EOSIO based RAM
LiquidAccounts - EOSIO accounts that live in vRAM instead of RAM
LiquidDNS - DNS service on the blockchain | contract table
Frontend stored on IPFS
user data is stored in the vRAM dapp::multi_index table (vRAM) | code
keys stored in dapp::multi_index table | code
keys created using the account name and password as seed phrases | code
eosjs-ecc’s seedPrivate method is used to create the keypair | code
logic to create LiquidAccount transactions | code

To launch locally:

zeus unbox cardgame
cd cardgame
zeus migrate
zeus run frontend main

Samples Boxes¶

zeus unbox <INSERT_BOX>

vRAM Boxes¶

coldtoken - vRAM based eosio.token
deepfreeze - vRAM based cold storage contract
vgrab - vRAM based airgrab for eosio.token
registry - vRAM based item registration

Zeus Extension Boxes¶

contract-migrations-extensions - contract create/deployment command template, deploy contract and allocate DAPP tokens
test-extensions - provides logic to test smart contract with unit tests
eos-extensions - install eos/eosio.cdt, launch local nodeos, launch system contracts
unbox-extensions - logic to unbox zeus boxes, list all boxes, and deploy a new box
demux - install EOSIO’s demux backend to capture events for contracts, zmq/state-history plugin options included

DAPP Services Boxes¶

ipfs-dapp-service - utilize the dapp::multi_index table to store data in IPFS (vRAM) instead of RAM
cron-dapp-service - schedule CRON tasks on-chain
oracle-dapp-service - provide oracle services
readfn-dapp-service - read a contract function without the need to submit a trx to the chain
vaccounts-dapp-service - EOSIO accounts that live in vRAM instead of RAM

Miscellaneous Boxes¶

microauctions - twin reverse dutch auctions used in DAPP’s generation event
eos-detective-reports - EOS Detective Reports - by EOSNation - https://eosdetective.io/
helloworld - Hello World
token - Standard eosio.token
airhodl - First ever Air-HODL

Zeus Options¶

please note: zeus commands are directory sensitive, all commands should be performed in root of box

Zeus compile¶

Compile a smart contract

zeus compile

# optional flags:

--all # compile all contracts
# default: true
--chain # chain to work on
# default: eos

Zeus migrate¶

Compile and migrate a smart contract to another network such as the Kylin Testnet, Jungle Testnet, or Mainnet

zeus import <CONTRACT_ACCOUNT_NAME> --owner-private-key <KEY> --active-private-key <KEY>
zeus create contract-deployment CONTRACT_NAME CONTRACT_ACCOUNT_NAME
zeus migrate

# optional flags:

--compile-all # compile all contracts
# default: true
--wallet # keosd wallet to use
# default: zeus
--creator-key # contract creator private key
# default: (eosio test key) 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
--creator # account to set contract to
# default: eosio
--reset # reset testing environment
# default: true
--chain # chain to work on
# default: eos
--network # network to work on (other options, kylin, jungle, mainnet)
# default: development (local)
--verbose-rpc # verbose logs for blockchain communication
# default: false
--storage-path # path for persistent storage',
# default: path.join(require('os').homedir(), '.zeus')
--stake # account EOSIO staking amount
# default: '30.0000'
--no-compile-all # do not compile contracts
--no-reset # do not reset local testing environment

Zeus test¶

Compile and unit test a smart contract

zeus test

# optional flags:

--compile-all # compile all contracts
# default: true
--wallet # keosd wallet to use
# default: zeus
--creator-key # contract creator key
# default: (eosio test key) 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
--creator # account to set contract to
# default: eosio
--reset # reset testing environment
# default: true

# default: development (local)
--verbose-rpc # verbose logs for blockchain communication
# default: false
--storage-path # path for persistent storage',
# default: path.join(require('os').homedir(), '.zeus')
--stake # account EOSIO staking amount
# default: '30.0000'
--no-compile-all # do not compile contracts
--no-reset # do not reset local testing environment

Zeus Import/Export Keys¶

Import and export keys to your Zeus wallet. Please note by default keys are imported without encryption.
