EOSafe
EOSafe is an on-chain smart-contract based wallet which maximizes fund security and minimizes losses in the event of a hack.
The project has been built entirely during the EOS global hackathon event in London. The chanllenge was:
Create an application on the EOSIO platform that improves the relationship between technology and a user's privacy or security.
Building and Using the System
Clone the repository
$ git clone https://github.com/xJonathanLEI/EOSafe
$ cd EOSafe
Build the contract
You'll need eos v1.2.5 for building the smart contract. Note that, however, you do NOT need eosio.cdt for this project, as the project uses eosiocpp due to compatibility considerations.
To build the contract:
$ cd contracts
$ ./build.sh
Three files wallet.wast, wallet.wasm and wallet.abi shall be generated in the contracts/build folder.
Spawn a local testnet
You may use anyway you like to spawn a local EOS testnet, but the project has provided a useful script for configuring nodeos for local testing:
$ cd ..
$ ./local_testnet.sh
Note that you may want to change the data path to your own choice. Under the default setting /data/eos a permission error may be thrown.
Bootstrapping the network
For easier testing, a mini project has been provided in bootstrapping. Note that the project assumes that nodeos has been built with CORE_SYMBOL set to EOS instead of the default SYS value.
To build nodeos with EOS as CORE_SYMBOL:
$ cd /path/to/eos/repository
$ ./eosio_build.sh -s EOS
Make sure you've installed it after building. Go back to the EOSafe repository, and run the bootstrapping script:
$ cd bootstrapping
$ npm install
$ node index.js
Once the bootstrapping process has been completed, the script will write System ready for demo! to the screen.
Run the front-end web app
A front-end web application for EOSafe has been built with React using create-react-app. To run the application:
$ cd ..
$ cd webapp
$ npm install
$ npm start
Now visit http://localhost:3000 in your web browser, and you shall see the login page for EOSafe.
