Whirlwind Swap Usage

Demo

Organization is a hedge fund manage multiple traders and multi-sigs. Traders get privacy through controller accounts.

The fund is a DAO or multi-sig that will first deposit to the Whirlwind pool. Then migrates the deposit anonymously to controller accounts controlled by traders or multi-sigs, depending on the institution's preferences.

The controller accounts can make swaps through only Osmosis, and withdrawals can only go back to the original DAO Treasury. Even if the zk-secret is compromised post-migration, all the attacker can do is make withdrawals.

Overview

  • Assume Alice, Bob, and Carol manage Fund F.
  • Assume Joe is a trade in Fund F.

Deposit

  • Alice, Bob, and Carol agree to deposit 1,000 USDC from their multisig wallet into Whirlwind.
  • They use MPC to calculate the credential and generate a deposit proof. Each holds onto their share of the secret s.
    • First use MPC to calculate the credential (C = f(secret, withdraw_address))
    • Use MPC to generate the deposit proof (Proof = f(secret, withdraw_address, C))

Migrate

  • Alice, Bob, and Carol can each hand Joe their shares.
  • Joe has everything he needs to create the migration proof
