More collaterals and debt limits​

BorrowOperations handles minting new stablecoins. Debt can be minted in withdrawBold, _openTrove (which is used in the batch manager and elsewhere too, so be careful), and _moveTokensFromAdjustment. Simple debt limit is just a uint256 stored in the TroveManager of each branch, and accessible to the CollateralRegistry via the index of the collateral. Getters and setters are added.

Does not handle the situation where interest accrued goes over the debt limit.

Debt limit can be raised by governance by a max factor of 2 at a time, by calling the CollateralRegistry which then calls the TroveManager for that collateral branch.

Debt limit can be lowered to any amount at any time. (Still must use the timelock)

LP Token Collateral​

New contracts for Aerodrome LP token support:

  • Gauge staking through AeroManager
  • AERO reward accounting with a 10% default claim fee, capped at 20%
  • Individual Stability Pools for LP branches
  • Composite price feeds for LP tokens
  • Redeemability configured per branch
