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

Use case

Wrap FIO Token:

  1. Alice executes wraptokens on FIO chain

  2. Oracle monitors wraptokens for transfers

  3. Oracle executes ERC-20 approve

  4. Alice calls ERC-20 blanceOf to get balance

  5. Alice executes ERC-20 transfer

Assumptions

  • Assume there is a single Oracle managing all transactions. Do NOT worry about multisigs, approvals, etc.

  • No validation on either chain is required.

Deployment

  • fio.wrapping contract deployed to DEV server

  • Hyperion connected to DEV server

  • oracle deployment?

  • ERC-20 deployment?

TBD

  • amounts on FIO are int64, amounts on ERC-20 are uint256

  • How will Alice execute the transfer? Are there standard interfaces or tools to do this?

  • No labels
