This effort prototypes a simplified end-to-end flow of FIO Wrapping.

Todo

• Only initial validation was done on wraptokens

• Update oracle to use _mint (to user address)

• Include Oracle validation

Use case

Wrap FIO Token:ERC20: https://github.com/fioprotocol/fio.erc20/blob/main/contracts/wfio.sol

Use case: Wrap FIO Token

1. Alice (dApp) executes wraptokens on FIO chain

2. Oracle monitors wraptokens for transfers

3. Oracle calls ERC20 _mint (to user address) wrap

4. ERC20 collects Oracle _mint wrap observation

5. When consensus reaching Oracle ERC20 calls _mint , the mint is executed

6. Alice can now view balanceOf wfio in Metamask/explorer
