Create Variable-Cap Asset

Variable-cap assets are fungible tokens for which additional quantities can be minted after creation.

Create the Asset

1. Write the token smart contract:

   1. https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol

   2. Functions

      1. name()

      2. symbol()

      3. decimals()

      4. totalSupply()

      5. balanceOf(account)

      6. transfer(recipient, amount)

      7. allowance(owner, spender)

      8. approve(spender, amount)

      9. transferFrom(sender, recipient, amount)

      10. increaseAllowance(spender, addedValue)

      11. decreaseAllowance(spender, subtractedValue)

      12. _transfer(sender, recipient, amount)

      13. _mint(account, amount)

      14. _burn(account, amount)

      15. _approve(owner, spender, amount)

      16. _setupDecimals(decimals_)

2. Compile your code into bytecode

3. Deploy your Variable-cap Asset by sending your code in a transaction to the Fantom network

4. Navigate to the Explorer to check that your token has been created

5. You can use the _mint function to create additional units of the token

This contract is designed to be unopinionated, allowing developers to access the internal functions in ERC-20 (such as _mint) and expose them as external functions in the way they prefer. On the other hand, ERC-20 Presets (such as ERC-20PresetMinterPauser) are designed using opinionated patterns to provide developers with ready to use, deployable contracts.
