Wrapping & Unwrapping

Overview

Wrapping

  • To wrap FIO Domains or Tokens a user executes a smart contract action, on the FIO Chain, to send the asset to a system contract controlled by Bridge Oracles.

  • Bridge Oracles independently monitor the FIO Chain and when a wrap action is received they record the observation on the target chain, e.g. Polygon, Ethereum.

  • Once enough observations are recorded, the asset is minted and transferred on the target chain to the address designated by the user.

  • On the FIO Chain, the asset remains in control of the Bridge Oracles until it is unwrapped.

Unwrapping

  • To unwrap FIO Domains or Tokens a user executes a smart contract action, on the remote chain, to return (burn) the asset.

  • Bridge Oracles independently monitor the remote chain and when an unwrap action is received they record the observation on the FIO Chain.

  • Once enough observations are recorded, the asset is transferred, on the FIO Chain, to the FIO Handle designated by the user.
