Smart contract managing the fund PoC.

Dependencies

You need to install NodeJS from https://nodejs.org/, truffle via command npm i -g truffle in the terminal.

You need to create account at infura for smart contract deployment.

You need metamask installed in your browser and you need some rinkeby ether for gas (may be obtained from here).

Smart contract deployment

To deploy smart contract on rinkeby network clone this repository and launch in the terminal following command from root folder of repository:

npm i
(export INFURA_TOKEN=$INFURA_TOKEN; export ETH_KEY=$ETH_KEY; truffle migrate --reset --network rinkeby)

Where $INFURA_TOKEN is access token you could obtain from infura and $ETH_KEY is your ethereum private key.

Deployment script prints to the terminal following log

Using network 'rinkeby'.

There are two smart contracts, CryptoYen and Fund with addresses 0xe9b49a8947077ede9817a3a0d8978e0f7f124487 and 0x4f724a33a013a4dfca92e57d4f3167733c6614ff (during your own deployment there will be other addresses). You may use these addresses to interact with smart contract.

Interacting with smart contract

CryptoYen is standard mintable ERC20 token contract. And Fund is contract managing the fund. You may get actual information about CryptoYen from etherscan. For previous example the url is https://rinkeby.etherscan.io/token/0xe9b49a8947077ede9817a3a0d8978e0f7f124487 . To interact with fund contract open https://trustpoc.bankex.com/ and type here address of Fund smart contract (or type something like https://trustpoc.bankex.com/?contract=0x4f724a33a013a4dfca92e57d4f3167733c6614ff). You need Metamask extension installed with active rinkeby network and same wallet as you use during deplyment. Then init smart contract with initData.csv and initBenefeteary.csv files stored in csv folder in the repository. As a result you can manage fund, obtain reports and update fund state with OBK_$date.csv files.
