Leverage Module

Abstract

This document specifies the x/leverage module of the Umee chain.

The leverage module allows users to supply and borrow assets, and implements various features to support this, such as a token accept-list, a dynamic interest rate module, incentivized liquidation of undercollateralized debt, and automatic reserve-based repayment of bad debt.

The leverage module depends directly on x/oracle for asset prices, and interacts indirectly with x/uibc, x/gravity, and the cosmos x/bank module as these all affect account balances.

Concepts

Accepted Assets

At the foundation of the leverage module is the Token Registry, which contains a list of accepted types.

This list is controlled by governance. Assets that are not in the token registry are nor available for borrowing or supplying.

Once added to the token registry, assets cannot be removed. In the rare case where an asset would need to be phased out, it can have supplying or borrowing disabled, or in extreme cases, be ignored by collateral and borrowed value calculations using a blacklist.

uTokens

Every base asset has an associated uToken denomination.

uTokens do not have parameters like the Token struct does, and they are always represented in account balances with a denom of UTokenPrefix + token.BaseDenom. For example, the base asset uumee is associated with the uToken denomination u/uumee.

Supplying and Borrowing

Users have the following actions available to them:

• Supply accepted asset types to the module, receiving uTokens in exchange.

  Suppliers earn interest at an effective rate of the asset's Supplying APY as the uToken Exchange Rate increases over time.

  Additionally, for assets denominations already enabled as collateral, the supplied assets immediately become collateral as well, causing their borrow limit to increase.

  If a user is undercollateralized (borrowed value > borrow limit), collateral is eligible for liquidation and cannot be withdrawn until the user's borrows are healthy again.

  Care should be taken by undercollateralized users when supplying token amounts too small to restore the health of their borrows, as the newly supplied assets will be eligible for liquidation immediately.

• Enable or Disable (MsgSetCollateral) a uToken denomination as collateral for borrowing.

  Enabling uTokens as collateral stores them in the leverage module account, so they cannot be transferred while in use. Disabling uTokens as collateral returns them to the user's account. A user cannot disable a uToken denomination if it would reduce their Borrow Limit below their total borrowed value.

  If the user is undercollateralized (borrowed value > borrow limit), enabled collateral is eligible for liquidation and cannot be disabled until the user's borrows are healthy again.

• MsgWithdraw supplied assets by turning in uTokens of the associated denomination. Withdraw respects the uToken Exchange Rate. A user can always withdraw non-collateral uTokens, but can only withdraw collateral-enabled uTokens if it would not reduce their Borrow Limit below their total borrowed value.

• MsgMaxWithdraw supplied assets by automatically calculating the maximum amount that can be withdrawn. This amount is calculated taking into account the available uTokens and collateral the user has, their borrow limit, and the available liquidity and collateral that can be withdrawn from the module respecting the min_collateral_liquidity of the Token.

• MsgBorrow assets of an accepted type, up to their Borrow Limit.

  Interest will accrue on borrows for as long as they are not paid off, with the amount owed increasing at a rate of the asset's Borrow APY.

• MsgMaxBorrow borrows assets by automatically calculating the maximum amount that can be borrowed. This amount is calculated taking into account the user's borrow limit and the module's available liquidity respecting the min_collateral_liquidity and max_supply_utilization of the Token.

• MsgRepay assets of a borrowed type, directly reducing the amount owed.

  Repayments that exceed a borrower's amount owed in the selected denomination succeed at paying the reduced amount rather than failing outright.

• MsgLiquidate undercollateralized borrows a different user whose total borrowed value is greater than their Liquidation Threshold.

  The liquidator must select a reward denomination present in the borrower's uToken collateral. Liquidation is limited by Close Factor and available balances, and will succeed at a reduced amount rather than fail outright when possible.

  If a borrower is way past their borrow limit, incentivized liquidation may exhaust all of their collateral and leave some debt behind. When liquidation exhausts the last of a borrower's collateral, its remaining debt is marked as bad debt in the keeper, so it can be repaid using module reserves.

Reserves

A portion of accrued interest on all borrows (determined per-token by the parameter ReserveFactor) is set aside as a reserves, which are automatically used to pay down bad debt.

Rather than being stored in a separate account, the ReserveAmount of any given token is stored in the module's state, after which point the module respects the reserved amount by treating part of the balance of the leverage module account as off-limits.

For example, if the module contains 1000 uumee and 100 uumee are reserved, then only 900 uumee are available for Borrow and Withdraw transactions. If 40 uumee of reserves are then used to pay off a bad debt, the module account will have 960 uumee with 60 uumee reserved, keeping the available balance at 900 uumee.

Oracle Rewards

At the same time reserves are accrued, an additional portion of borrow interest accrued is transferred from the leverage module account to the oracle module account to fund its reward pool. Because the transfer happens instantaneously and the accounts are separate, there is no need to module state to track the amounts.

Derived Values

Some important quantities that govern the behavior of the leverage module are derived from a combination of parameters, borrow values, and oracle prices. The math and reasoning behind these values will appear below.

As a reminder, the following values are always available as a basis for calculations:

• Account token and uToken balances, available through the bank module.
• Total supply of any uToken denomination, stored in leverage module State.
• The leverage module account balance, available through the bank module.
• Collateral uToken amounts held in the leverage module account for individual borrowers, stored in leverage module State.
• Borrowed denominations and adjusted amounts for individual borrowers, stored in leverage module state).
• Interest scalars for all borrowed denominations, which are used with adjusted borrow amounts
• Total adjusted borrows summed over all borrower accounts.
• Leverage module Parameters
• Token parameters from the Token Registry

The more complex derived values must use the values above as a basis.

Adjusted Borrow Amounts

Borrow amounts stored in state are stored as AdjustedBorrow amounts, which can be converted to and from actual borrow amounts using the following relation:

AdjustedBorrow(denom,user) * InterestScalar(denom) = BorrowedAmount(denom,user)

When interest accrues on borrow positions, the InterestScalar of the denom is increased and the adjusted borrow amounts remain unchanged.

uToken Exchange Rate

uTokens are intended to work in the following way:

The total supply of uTokens of a given denomination, if exchanged, are worth the total amount of the associated token denomination in the lending pool, including that which has been borrowed out and any interest accrued on it.

Thus, the uToken exchange rate for a given denom and associated uDenom is calculated as:

exchangeRate(denom) = [ ModuleBalance(denom) - ReservedAmount(denom) + TotalBorrowed(denom) ] / TotalSupply(uDenom)

In state, uToken exchange rates are not stored as the can be calculated on demand.

Exchange rates satisfy the invariant exchangeRate(denom) >= 1.0

Supply Utilization

Supply utilization of a token denomination is calculated as:

supplyUtilization(denom) = TotalBorrowed(denom) / [ ModuleBalance(denom) - ReservedAmount(denom) + TotalBorrowed(denom) ]

Supply utilization ranges between zero and one in general. In edge cases where ReservedAmount(denom) > ModuleBalance(denom), utilization is taken to be 1.0.

Borrow Limit

Each token in the Token Registry has a parameter called CollateralWeight, always less than 1, which determines the portion of the token's value that goes towards a user's borrow limit, when the token is used as collateral.

A user's borrow limit is the sum of the contributions from each denomination of collateral they have deposited.

  collateral := GetBorrowerCollateral(borrower) // sdk.Coins
  for _, coin := range collateral {
    borrowLimit += GetCollateralWeight(coin.Denom) * TokenValue(coin) // TokenValue is in usd
  }

For tokens with hith historic prices enabled (indicated by a HistoricMedians parameter greater than zero), each collateral TokenValue is computed with PriceModeLow, i.e. the lower of either spot price or historic price is used.

Historic Borrow Limit, Value

The leverage module also makes use of the oracle's historic prices to enforce an additional restriction on borrowing.

The logic is:

• For any MsgBorrow, MsgMaxBorrow, MsgDecollateralize, MsgWithdraw, or MsgMaxWithdraw
• The borrower’s borrowed value must be less than their borrow limit, with borrowed value being computed using PriceModeHigh, i.e. the higher of either spot price or historic price is used.
• Where historic prices are defined as the Median of the last N historic medians from the oracle module with N = Token.HistoricMedians in the leverage registry
• Else the transaction fails

Liquidation Threshold

Each token in the Token Registry has a parameter called LiquidationThreshold, always greater than or equal to collateral weight, but less than 1, which determines the portion of the token's value that goes towards a borrower's liquidation threshold, when the token is used as collateral.

A user's liquidation threshold is the sum of the contributions from each denomination of collateral they have deposited. Any user whose borrow value is above their liquidation threshold is eligible to be liquidated.

  collateral := GetBorrowerCollateral(borrower) // sdk.Coins
  for _, coin := range collateral {
     liquidationThreshold += GetLiquidationThreshold(coin.Denom) * TokenValue(coin) // TokenValue is in usd
  }

Borrow APY

Umee uses a dynamic interest rate model. The borrow APY for each borrowed token denomination changes based on that token Supply Utilization.

The Token struct stored in state for a given denomination defines three points on the Utilization vs Borrow APY graph:

• At utilization = 0.0, borrow APY = Token.BaseBorrowRate
• At utilization = Token.KinkUtilization, borrow APY = Token.KinkBorrowRate
• At utilization = 1.0, borrow APY = Token.MaxBorrowRate

When utilization is between two of the above values, borrow APY is determined by linear interpolation between the two points. The resulting graph looks like a straight line with a "kink" in it.

Supplying APY

The interest accrued on borrows, after some of it is set aside for reserves, is distributed to all suppliers (i.e. uToken holders) of that denomination by virtue of the uToken exchange rate increasing.

While Supplying APY is never explicitly used in the leverage module due to its indirect nature, it is available for querying and can be calculated:

SupplyAPY(token) = BorrowAPY(token) * SupplyUtilization(token) * [1.0 - ReserveFactor(token)]

Close Factor

When a borrower is above their borrow limit, their open borrows are eligible for liquidation. In order to reduce the severity of liquidation events that can occur to borrowers that only slightly exceed their borrow limits, a dynamic CloseFactor applies.

A CloseFactor can be between 0 and 1. For example, a CloseFactor = 0.25 means that a liquidator can at most pay back 25% of a borrower's current total borrowed value in a single transaction.

Two module parameters are required to compute a borrower's CloseFactor based on how far their TotalBorrowedValue exceeds their BorrowLimit (both of which are USD values determined using price oracles)

portionOverLimit := (TotalBorrowedValue / BorrowLimit) - 1
// e.g. (1100/1000) - 1 = 0.1, or 10% over borrow limit

if portionOverLimit > params.CompleteLiquidationThreshold {
  CloseFactor = 1.0
} else {
  CloseFactor = Interpolate(             // linear interpolation
    0.0,                                 // minimum x
    params.CompleteLiquidationThreshold, // maximum x
    params.MinimumCloseFactor,           // minimum y
    1.0,                                 // maximum y
  )
}

Note that close factor is always 1.0 if borrowed value is below the module parameter SmallLiquidationSize.

Total Supplied

The TotalSupplied of a token denom is the sum of all tokens supplied to the asset facility, including those that have been borrowed out and any interest accrued, minus reserves.

TotalSupplied(denom) = ModuleBalance(denom) - ReservedAmount(denom) + TotalBorrowed(denom)

State

The x/leverage module keeps the following objects in state:

• Registered Token (Token settings)*: 0x01 | denom -> Token
• Adjusted Borrowed Amount: 0x02 | borrowerAddress | denom -> sdk.Dec
• Collateral Setting: 0x03 | borrowerAddress | denom -> 0x01
• Collateral Amount: 0x04 | borrowerAddress | denom -> sdk.Int
• Reserved Amount: 0x05 | denom -> sdk.Int
• Last Interest Accrual (Unix Time): 0x06 -> int64
• Bad Debt Instance: 0x07 | borrowerAddress | denom -> 0x01
• Interest Scalar: 0x08 | denom -> sdk.Dec
• Total Borrowed: 0x09 | denom -> sdk.Dec
• Totak UToken Supply: 0x0A | denom -> sdk.Int

The following serialization methods are used unless otherwise stated:

• sdk.Dec.Marshal() and sdk.Int.Marshal() for numeric types
• []byte(denom) | 0x00 for asset and uToken denominations (strings)
• address.MustLengthPrefix(sdk.Address) for account addresses
• cdc.Marshal and cdc.Unmarshal for gogoproto/types.Int64Value wrapper around int64

Note that collateral settings and instances of bad debt are both tracked using a value of 0x01. In both cases, the 0x01 means true ("enabled" or "present") and a missing or deleted entry means false. No value besides 0x01 is ever stored.

Adjusted Total Borrowed

Unlike all other quantities in state, AdjustedTotalBorrowed values are not present in imported and exported genesis state.

Instead, every time an individual AdjustedBorrow is set during ImportGenesis, its respective token's AdjustedTotalBorrowed is increased by the same amount. Thus, it is indirectly imported as the sum of individual positions.

Similarly, AdjustedTotalBorrowed is never set independently during regular operations. It is modified during calls to setAdjustedBorrow, always increasing or decreasing by the change in the individual borrow being set.

Queries

See leverage query proto for list of supported queries.

Additionally, the query liquidation-targets is only enabled if the node is started with a flag:

# Enabled
umeed start --enable-liquidator-query

# Enabled
umeed start -l

# Disabled
umeed start

Messages

See leverage tx proto for list of supported messages.

Update Registry Proposal

Update-Registry gov proposal will adds the new tokens to token registry or update the existing token with new settings.

Under certain conditions, tokens will be automatically deleted:

• The token has been blacklisted by a previous proposal or the current one
• The token has not been supplied to the module, so there are no uTokens, borrows, or collateral associated with it.

The conditions allow for mistakenly registered tokens which have never been used to be removed from the registry. It is not safe to remove a token with active supply or borrows, so those stay listed in the registry when blacklisted.

CLI

umeed tx gov submit-proposal [path-to-proposal-json] [flags]

Example:

umeed tx gov submit-proposal /path/to/proposal.json --from umee1..

// Note `authority` will be gov module account address in proposal.json
umeed q auth module-accounts -o json | jq '.accounts[] | select(.name=="gov") | .base_account.address'

Events

See leverage events proto for list of supported events.

Params

See leverage module proto for list of supported module params.

End Block

Every block, the leverage module runs the following steps in order:

• Repay bad debts using reserves
• Accrue interest on borrows

Sweep Bad Debt

Borrowers whose entire balance of collateral has been liquidated but still owe debt are marked by their final liquidation transaction. This periodic routine sweeps up all marked address | denom bad debt entries in the keeper, performing the following steps for each:

• Determine the about of Reserves in the borrowed denomination available to repay the debt
• Repay the full amount owed using reserves, or the maximum amount available if reserves are insufficient
• Emit a "Bad Debt Repaid" event indicating amount repaid, if nonzero
• Emit a "Reserves Exhausted" event with the borrow amount remaining, if nonzero

Accrue Interest

At every epoch, the module recalculates Borrow APY and Supplying APY for each accepted asset type, storing them in state for easier query.

Borrow APY is then used to accrue interest on all open borrows.

After interest accrues, a portion of the amount for each denom is added to the state's ReservedAmount of each borrowed denomination.

Then, an additional portion of interest accrued is transferred from the leverage module account to the oracle module to fund its reward pool.
