uToken_exchange_rate:
type: string
description: >-
uToken Exchange Rate is the amount of base tokens received
when withdrawing 1 uToken. For example, a uToken exchange rate
of 1.5 means a supplier receives 3 uumee for every 2 u/uumee
they wish to withdraw. The same applies in reverse: supplying
3 uumee would award 2 u/uumee at that time.
supply_APY:
type: string
description: >-
Supply APY is the current interest rate suppliers are
receiving for their deposits. For example, 0.11 would mean 11%
APY. Supply APY is always less than borrow APY.
borrow_APY:
type: string
description: >-
Borrow APY is the current interest rate borrowers are being
charged on their loans. For example, 0.2 would mean 20% APY.
supplied:
type: string
description: >-
Supplied is the total amount of tokens supplied to the the
system by all suppliers, including any interest earned. This
includes that tokens which have been borrowed out or enabled
as collateral, but excludes reserves. Supplied is denominated
in base tokens, so exponent must be applied to convert to
symbol denom.
reserved:
type: string
description: >-
Reserved is the total amount of tokens held in reserve by the
module for emergencies. Reserves are always excluded from
total supply, borrow, collateral, and liqduidity queries.
Reserves are denominated in base tokens, so exponent must be
applied to convert to symbol denom.
collateral:
type: string
description: >-
Collateral is the total amount of uTokens collateralized by
all borrowers. Collateral is denominated in uTokenso, so both
uToken exchange rate and exponent must also be applied to
convert to symbol denom. For example, if collateral is 4000000
u/uumee and uToken exchange rate is 1.2, then 5 UMEE have been
collateralized.
borrowed:
type: string
description: >-
Borrowed is the total amount of debt in this token held across
all borrowers. It is denominated in base tokens, so exponent
must be applied to convert to symbol denom.
liquidity:
type: string
description: >-
Liquidity is the amount of a token that has been supplied but
not yet borrowed or reserved. It is denominated in base
tokens, so exponent must be applied to convert to symbol
denom.
maximum_borrow:
type: string
description: >-
Maximum Borrow is the amount of a token that is available for
borrowing, including that which has already been borrowed out.
This amount is less than total supply due to safety limits. It
is denominated in base tokens, so exponent must be applied to
convert to symbol denom. For example, if borrowed is 3000000
uumee and maximum borrow is 4000000 uumee, then 1 UMEE is
currently available for borrowing.
maximum_collateral:
type: string
description: >-
Maximum Collateral is the amount of a token that can be
collateralized, including that which is already collateral.
This amount is less than total supply due to safety limits. It
is denominated in uTokens, so both uToken exchange rate and
exponent must be applied to convert to symbol denom. For
example, if collateral is 4000000 u/uumee, uToken exchange
rate is 1.2, and maximum borrow is 7000000 uumee, then a
maximum of 2 additional UMEE is permitted to be
collateralized.
minimum_liquidity:
type: string
description: >-
Minimum Liquidity is the minimum amount of liquidity in the
module required by safety limits, based on the current
collateral. It is denominated in base tokens, so exponent must
be applied to convert to symbol denom. For example, if
liquidity is 9000000 uumee and minimum liquidity is 8000000
uumee, then a maximum of 1 additional UMEE is currently
available for borrowing or withdrawal.
uToken_supply:
type: string
description: >-
uToken Supply is the total amount of a base token's associated
uToken in circulation.
available_borrow:
type: string
description: >-
Available Borrow is the maximum additional amount of base
tokens than can be borrowed based on current liquidity and
system safety limits. It can also be calculated by
MIN(maximum_borrow - borrowed, liquidity - minimum_liquidity).
It is denominated in base tokens, so exponent must be applied
to convert to symbol denom. A negative availability means
safety limits have been exceeded and borrowing is temporarily
unavailable.
available_withdraw:
type: string
description: >-
Available Withdraw is the maximum amount of uTokens than can
currently be withdrawn based on liquidity and system safety
limits. It can also be calculated by (liquidity -
minimum_liquidity). It is denominated in uTokens, so both
uToken exchange rate and exponent must be applied to convert
to symbol denom. A negative availability means safety limits
have been exceeded and withdrawal is temporarily unavailable.
available_collateralize:
type: string
description: >-
Available Collateralize is the maximum additional amount of
uTokens than can be collateralized based on current liquidity
and system safety limits. It can also be calculated by
(maximum_collateral, - collateral). It is denominated in
uTokens, so both uToken exchange rate and exponent must be
applied to convert to symbol denom. A negative availability
means safety limits have been exceeded and additional
collateral cannot be created until more liquidity is present.
oracle_historic_price:
type: string
description: >-
Oracle Historic Price is the historic USD value of a token.
Historic price is defined as the median of the last N historic
median prices from the oracle module, with N being this
token's HistoricMedians in the leverage registry. Current
price is used if required medians is zero. Price is nil when
the oracle is down or insufficient historic medians are
available.

Complete Liquidation Threshold determines how far between

Close Factor determines the portion of a borrower's
position that can be
liquidated in a single event. Minimum Close Factor is
Close Factor at
liquidation_threshold. 0.1 means that that 10% of the
borrower position can
be liquidated when the borrowed value passes the

close_factor scales linearly between minimum_close_factor

reaching its maximum when borrowed value passes
complete_liquidation_threshold. We can put it into the

blacklist:

Blacklist should only be used to eliminate an asset
