EOSDevHelper is a cross-platform EOS PC wallet tool,which is developed by



ATTENTION: This Tool is used for developing EOS smart contract, it is NOT a real EOS wallet. The wallet in this tool is testnet only, please do NOT import your EOS private keys.



  The EOSDevHelper program is a light weighted wallet build on EOSIO ecology. It provides private basic key store with encryptions, signature, validation functions, and etc. Developers can use this tool connect the EOSIO testnet, and test the wallet/account/contracts interface in a more convenient way.



Compile from source code/如何从源码编译:


 1. install QT >= 5.8

 2. download our git repository.

git clone --recurse-submodules

 3. open Qt Creator and choose "Open Project", select the "src/" and open

 4. select Build from QT menu and Run it.

For ubuntu, if build with errors like connot find -lGL, this means the openGL development library is missing. Just using this command to install: sudo apt-get install build-essential libgl1-mesa-dev

About OracleChain/有关欧链

As the world’s first application built on an EOS ecosphere, OracleChain needs to meet the demands of the Oracle (oracle machine) ecosystem by efficiently linking blockchain technology services with various real-life scenarios, thereby delving into this immense tens of billions of dollars valuation market.


As a decentralized Oracle technology platform based on the EOS platform, the autonomous Proof-of-Reputation & Deposit mechanism is adopted and used as a fundamental service for other blockchain applications.In addition to Oracle services that provide real-world data to the blockchain, Oracle services that provide cross-chain data are also offered. Given that OracleChain can accomplish the functions of several prediction market applications, such as Augur and Gnosis, OracleChain can also support smart contract businesses that require high-frequency access to outside data in certain scenarios, such as Robo-Advisor.

OracleChain是一个多区块链的去中心化Oracle技术平台,采用自主的PoRD机制,将现实世界数据引入区块链,并将此作为基础设施为其他区块链应用提供服务。 OracleChain将在区块链内提供现实世界数据的Oracle服务,同时还可以提供跨链数据的Oracle服务。基于OracleChain除了能实现Augur、Gnosis等预测市场(Prediction Market)应用的功能之外,还能支撑对链外数据有更高频率访问需求的智能合约业务,比如智能投顾等场景。

OracleChain will nurture and serve those blockchain applications that change the real world. Our mission is to “Link Data, Link World,” with the aim of becoming the infrastructure linking the real world with the blockchain world.


By achieving intra-chain and extra-chain data connectivity, we aspire to create a service provisioning platform that can most efficiently gain access to extra-chain data in the future blockchain world.
