NAGA Coin Smart Contract



Install dependencies:

npm i


First, compile the contract:

npm run compile

To deploy the smart contract on the development network, run:

npm run deploy-dev

To deploy the smart contract on the Ropsten testnet, run:

npm run deploy-ropsten

Be careful! Every deploy on the same network replaces metadata (including the contract address) stored in the build directory.


To mint tokens, prepare a JSON file distribution.json. For example:

  "0x8A6d9138e960577D230Ba5F86f872418EA8c0506": {
    "amount": 1.23,
    "releaseTime": 1519862400
  "0xf6d1fa4fd83ba3e0c77642756e95917b8a47c1dd": {
    "amount": 0.000000000000000001,
    "releaseTime": 0

Then run (on the development network):

npm run mint-dev distribution.json

Or on the Ropsten testnet:

npm run mint-ropsten distribution.json

Finish minting

On the development network:

npm run finish-dev

On the Ropsten testnet:

npm run finish-ropsten

Running tests

Run testrpc:

npm run testrpc

While testrpc is running, run tests:

npm test

Due to use of testrpc’s evm_increaseTime, you should restart testrpc after each run of tests.

Ropsten testnet setup

  1. Install geth:
  2. Run it on the Ropsten testnet:
     geth --testnet --rpc
  3. Find in the beginning of the geth log a line like this one:
     IPC endpoint opened: /Users/username/Library/Ethereum/testnet/geth.ipc
  4. Open another terminal and run (using the file path from the previous step):
     geth attach /Users/username/Library/Ethereum/testnet/geth.ipc
  5. Wait for the blockchain to sync. In the geth log, it looks like:
     ... Imported new chain segment               blocks=1 ...

    Also you can run eth.syncing in the geth console. It should return false instead of sync information.

  6. We need to create an account. In the geth console, run:

    When it prompts for a passphrase, input a strong one (32 random chars, for example). Of course, you have to store it somewhere.

  7. Now restart geth with the unlock parameter:
     geth --testnet --rpc --unlock "0x0000000000000000000000000000000000000000"

    Instead of 0x0000000000000000000000000000000000000000, use account you created in the previous step. While starting, geth will prompt you for the passphrase.

  8. Transfer some ETH to account to pay for gas.
