    Catena Smart Contract

    npm (scoped) Build Status

    Used to publish NRC public funding disclosures and on the Ethereum blockchain.

    Built using the Truffle Framework.

    Usage

    Install:

    npm install @catena/contract

    Example usage:

    const { CatenaContract } = require('@catena/contract')
    
    const catenaContract = CatenaContract(web3)
    
    catenaContract.getDisclosure(687)
      .then(result => console.log(result))

    For more information on using a truffle contract see Truffle Docs.

    Development

    Setup

    • Install node dependencies: npm install
    • Install an ethereum node: Parity or Geth

    Parity

    Parity works well but you must have the geth flag enabled or truffle migrations will fail.

    parity --chain rinkeby --geth

    Optionally, add the following for more convenient testing:

    --unlock <address> --password <passwordfile>

    Geth

    If connecting to an actual testnet or mainnet network, you will first need time to sync the blockchain. Running in --fast mode helps:

    geth --fast --rpc --rpcapi eth,net,web3,personal --rpccorsdomain="*"

    Using mist:

    ./mist --syncmode=fast --cache=1024

    To test using rinkeby:

    geth --rinkeby --fast --rpc --rpcapi eth,net,web3,personal --rpccorsdomain="*"

    Attaching to the geth node (assuming it's on localhost):

    geth attach http://127.0.0.1:8545

    • geth commands

    From the geth console you can look at the balance of your primary account:

    eth.getBalance("0x0d9cf77f30e7af582762418d7011ef486a388275")

    Also, you can unlock your primary account to use its ether for testing or execution:

    personal.unlockAccount("0x0d9cf77c30e7af582752418d7011ef486a388275", "password123", 0)

    Testing

    Testing the smart contract can be done as follows:

    npm test

    This will start a testrpc server and run truffle test. To run a specific test:

    npm test test/DisclosureManageTests.sol

    If you want to run tests on a different network like rinkeby, for example, use:

    npm test --network rinkeby

    Install

    npm i @catena/contract
