# Generator Token

A Generator token is a token which mints tokens over a certain period following well defined properties and the tokens are then sent fo the destination_address as specified by the owner

### Properties

The properties:

- name e.g. INCAG in case of ThreeFold
- owner_address, is the person who owns the generator token
- dest_token_name e.g. INCA in case of ThreeFold
- dest_chain e.g. SOLANA
- dest_address, where the minted tokens will be sent too
  - owner can change the dest address
- description
- code = smart contract related
  - smart_contract_addr: address of the smart contract
  - this smart contract executes the code as needed to execute this contract, this smart contract will ask the minter code to create tokens as needed.
- minter related
  - minter_contract_addr: address of the smart contract which generates the tokens (minting) 
  - info about minter, the minter creates the Generator Tokens as well as the Destination Tokens
- source related
  - can be empty if there is no source token
  - source_token_name e.g. TFT (can also be address)
  - source_token_chain e.g. STELLAR
  - sourcetable
    - list of the sourcetokens (amount, src_address) e.g. 1000 TFT was input of this INCAG token.
- mintingtable
  - nr of $dest_token_name e.g. INCA to be minted over which time 
  - is a table with date + minting amount of our specific "dest_token" which is generated (minted) over time
- acceleration_table
  - accelerated minting rules
  - per row we find a date, oracleaddress, minimum, maximum, nrminted e.g. if oracle about INCA price is higher than 0.5 USD, there is no max, then we mint e.g. 1000 INCA on a specific Date
the INCAG
  - if not specified then the owner of the INCAG can freely define the destination
- clawback (stop the minting and if any incoming tokens, send them back to the originator)
  - clawback_multisig_accounts e.g. accounts which can instantiate a clawback
  - clawback_multisig_min_signature e.g. nr of signatures needed for clawback
  - clawback_address (*is only relevant if the originating tokens come from somewhere*)
  - when clawback is executed it basically means the generator token no longer exists
