Cudos Token

Cudos Token Smart Contract

  • Is ERC20 compliant
  • Responsible for holding all tokens balances on the Cudos platform infrastructure
  • The CudosToken has the following properties
    • Defines a token name - CudosToken
    • Defines a token symbol - CUDOS
    • Defines the number of decimals the token is divisible by - 18
    • Defines the total supply of tokens - 10 billion tokens are created upon contract creation
  • The token has a transfersEnabled flag that can be toggled to enable transfers for all. Only admin addresses defined in the linked CudosAccessControls contract can toggle this flag.
  • Whitelisted addresses can transfer tokens even if the transfersEnabled flag is set to false. The whitelist is defined in the linked CudosAccessControls contract.

Cudos Vesting Contracts

  • VestingContract is not directly based on a specific EIP but does borrow some leanings from the open-zepplin library
  • Designed to work with Cudos ERC20 token contract but would support any standard ERC20 contract
  • General rules are as follows:
    • Single vesting schedule per address
    • Schedules are defined as address, total amount, total time vested
    • User can withdraw every second and will issue allowance since last draw down
    • Cudo is in control of setting up and cancelling any vesting schedules
    • Utility methods can be called to gain insight into a beneficiaries remaining allowance and draw down rates

Cudos Token set-up steps

  • Deploy CudosAccessControls from a Cudo admin account. The deployment account will be automatically granted the default admin role.
  • Deploy CudosToken from a Cudo account supplying the address of the access control contract
