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

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 wrap

  4. ERC20 collects Oracle wrap observation

  5. When consensus reaching ERC20 calls _mint

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