Call Notes

Withdrawals Contract

  • Not many changes since last week
  • Waiting for feedback before continuing the implementation _ 3 possibilities 1. Declare that the GNO token on the GC is a canonical token _ Mint it when the contract has not enough tokens _ Violates the first principles of the GNO token 2. Mint an GNO on GC token when the contract has not enough tokens _ Violates the bridge pledge logic 3. Do not issue a token when the contract has not enough tokens, but instead leave a note that in the future the user will be able to receive funds if they will be on the withdrawal contract (violates the logic of creating an mGNO token because of staking) E.g. “promissory”GNO
