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
