Create a Fixed-cap Asset

PreviousDeploy a Smart ContractNextxDAI Chain

Last updated 1 year ago

Was this helpful?

Fixed-cap assets are fungible tokens for which the supply is determined at the time of asset creation. No additional quantities can be generated afterwards.

Create the Asset

1. Write the token smart contract

Extension of ERC20 that adds a cap to the supply of tokens

This contract is designed to be unopinionated, allowing developers to access the internal functions in ERC20 (such as ) and expose them as external functions in the way they prefer. On the other hand, (such as ) are designed using opinionated patterns to provide developers with ready to use, deployable contracts.

Functions

Fixed-cap Assets

  • constructor(cap)

  • cap()

  • _beforeTokenTransfer(from, to, amount)

General

  • name()

  • symbol()

  • decimals()

  • totalSupply()

  • balanceOf(account)

  • transfer(recipient, amount)

  • allowance(owner, spender)

  • approve(spender, amount)

  • transferFrom(sender, recipient, amount)

  • increaseAllowance(spender, addedValue)

  • decreaseAllowance(spender, subtractedValue)

  • _transfer(sender, recipient, amount)

  • _mint(account, amount)

  • _burn(account, amount)

  • _approve(owner, spender, amount)

  • _setupDecimals(decimals_)

2. Compile your code into bytecode

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