Development

This page explains how to compile/deploy/test/interact with smart contracts. There are four major contracts which are Cyclone token, GovernorAlpha/Timelock, Aeolus, and Cyclone (Coin, ERC20)

Preparation

  1. 1.
    Install truffle
    npm install -g truffle
  2. 2.

    npm install
  3. 3.
    Install ioctl - the command-line tool to interact with IoTeX blockchain
install ioctl following the instructions: https://docs.iotex.io/developer/ioctl/install.html​

Compile contracts

npm run build:contract

  4. 4.
    Invoke ct.addMinter() to set cc and ec to be minters for CYC token
    ioctl contract invoke function CYCTOKEN_ADDRESS CYCTOKEN_ABI_PATH "addMinter" --with-arguments '{"_minter": CoinCyclone_ADDRESS}'
    ioctl contract invoke function CYCTOKEN_ADDRESS CYCTOKEN_ABI_PATH "addMinter" --with-arguments '{"_minter": ERC20Cyclone_ADDRESS}'
  5. 5.
    Invoke as.addAddressToWhitelist() to set cc and ec to be whitelists for Aeolus to invoke addReward()
    ioctl contract invoke function AEOLUS_ADDRESS AEOLUS_ABI_PATH "addAddressToWhitelist" --with-arguments '{"addr": CoinCyclone_ADDRESS}'
    ioctl contract invoke function AEOLUS_ADDRESS AEOLUS_ABI_PATH "addAddressToWhitelist" --with-arguments '{"addr": ERC20Cyclone_ADDRESS}'

Test contracts

  1. 1.
    node version nvm use 11.15.0
  2. 2.
    build zk circuits npm run build
  3. 3.
    if you want to use test network, just run npm run test (default).
    If you want to use development network,
    • modify truffle-config.js (uncomment development network)
    • run ganache-cli i 1337
    • run npm run test

Interaction with Cyclone contracts [Anonymity Mining]

  1. 1.
    Requirements
  2. 2.
    nvm use 11.15.0
  3. 3.
    npm install -g npx
  4. 4.
    Set up .env file
    • cp .env.example .env
    • vi .env - add your private key, deployed contract address and denomination value
  5. 5.
    Build zk circuits: npm run build. Note that if you want to build zk circuits (including verifier.sol, proof/verify-keys) locally, you need to:
    • npm uninstall websnark
    • npm install [email protected]"git+https://github.com/tornadocash/websnark.git#2041cfa5fa0b71cd5cca9022a4eeea4afe28c9f7"
    • npm run build:local - It might take more than 10 minutes as it performs the trust-setup locally.
  6. 6.
    Deposit
    • Testnet
      ./client.js deposit IOTX|XRC20 --rpc http://api.testnet.iotex.one:80
    • Mainnet
      ./client.js deposit IOTX|XRC20 --rpc http://api.iotex.one:80
  7. 7.
    Withdraw
    • Testnet
      ./client.js withdraw NOTE RECIPIENT_ADDRESS --rpc http://api.testnet.iotex.one:80 --relayer RELAYER_URL
    • Mainnet
      ./client.js withdraw NOTE RECIPIENT_ADDRESS --rpc http://api.iotex.one:80 --relayer RELAYER_URL

Interaction with Aeolus contract [Liquidity Mining]

  1. 1.
    Add Liquidity for CYC/IOTX on MimoFactory and receive CYC-IOTX LP Token
  2. 2.
    Deposit
  • Approve CYC-IOTX LP Token
ioctl xrc20 approve AEOLUS_ADDRESS AMOUNT -c LPTOKEN_ADDRESS
  • Deposit CYC-IOTX LP Token
ioctl contract invoke function AEOLUS_ADDRESS abi/Aeolus.json "deposit" --with-arguments '{"_amount": AMOUNT}'
3. Withdraw
ioctl contract invoke function AEOLUS_ADDRESS abi/Aeolus.json "withdraw" --with-arguments '{"_amount": AMOUNT}'

Interaction with GovernorAlpha contract [Governance]

  1. 1.
    Self-delegate or delegate your CYC token for governance. If you do not delegate your votes, the token will not be considered as voting power.
ioctl contract invoke function CYCTOKEN_ADDRESS abi/CycloneToken.json "delegate" --with-arguments '{"delegatee": ADDRESS_YOU_WANT_TO_DELEGATE}' -s mainnet -y
2. Propose a new change in cyclone contracts such as updateConfig, changeGovDAO, and updateVerifier. The proposer should have more than 1000 CYC Token. Voting will run for 3 days. -- Use abi-encoder to get encoded argument data.
ioctl contract invoke function GOVERNOR_ADDRESS abi/GovernorAlpha.json "propose" --with-arguments '{"targets": [CYCLONE_ADDRESS], "values": [0], "signatures": ["updateConfig(uint256,uint256,uint256,uint256)"], "calldatas": ["..."], "description": "update configs in cyclone contract"}'
3. During the 3 days of voting duration, token holders who self-delegate or delegate can cast votes for a certain proposal.
ioctl contract invoke function GOVERNOR_ADDRESS abi/GovernorAlpha.json "castVote" --with-arguments '{"proposalId": 1, "support": true}'
4. After 3 days of voting duration, if the proposal gets more than 4000 CYC votes, the proposer can queue the transaction into Timelock.
ioctl contract invoke function GOVERNOR_ADDRESS abi/GovernorAlpha.json "queue" --with-arguments '{"proposalId": 1}'
5. After the timelock delay, the proposer can execute the transaction in timelock.
ioctl contract invoke function GOVERNOR_ADDRESS abi/GovernorAlpha.json "execute" --with-arguments '{"proposalId": 1}'
