MoneyTokes

This project contains a smart contract Tokes that allows users to mint an NFT, called a "Toke" containing ETH that can be claimed by whoever is the owner.

This Toke can be transferred like any other NFT but can also have an expiration date after which its creator can redeem the funds if they aren't already claimed by the owner.

Usage

• mintEtherToke(address to, uint256 expiration)
  • mints a Toke containing msg.value and sends it to to
  • expiration is a Unix timestamp, 0 if the Toke can't expire
  • emits MintEtherToke(from, to, tokeId, amount, expiration)
• mintERC20Toke(address token, address to, uint256 amount, uint256 expiration)
  • mints a Toke containing amount of token and sends it to to
  • expiration is a Unix timestamp, 0 if the Toke can't expire
  • emits MintERC20Toke(from, to, tokeId, token, amount, expiration)
• redeem(uint256 tokeId)
  • burns Toke tokeId and sends the funds to the owner
  • can only be called by the owner or an approved address
  • doesn't work if the Toke expired
  • emits RedeemToke(to, tokeId)
• breakToke(uint256 tokeId)
  • burns Toke tokeId but sends the funds to the creator (minter)
  • can only be called by the creator, after expiration
  • emits RedeemToke(to, tokeId)
