Synthetic asset smart contract for the Liquid network

Synthetic assets are collateral-backed assets whose value fluctuates depending on a reference price. We propose a scheme where anyone can lock collateral on the Liquid Network to issue assets that track the price of a chosen real-world asset, such as dollars or stocks. The Elements enhanced scripting capabilities allow non-interactive redemption and liquidation when the collateral's value is underwater, with the possibility to top up the collateral to prevent liquidation.

Detailed description document is published with each release.

TL;DR

Actors

  • Issuer/Liquidator
  • Sponsor
  • Oracle

Flow

  1. Issuer mints an asset with zero supply (ie. sTSLA)
  2. Sponsor locks collateral (ie. USDt) in the contract to mint the asset at the current reference price upon mutual agreement on liquidation target.
  3. If the collateral's value is underwater, Issuer can liquidate after burning the asset and presenting Oracle's signature on the reference price.
  4. Sponsor can prevent liquidation via collateral top-up in collaboration with the Issuer to create a new contract.

NOTICE: Sponsor can always redeem in a non-interactive fashion his collateral burning the asset and sending a payout fee to the Issuer.
