# Checker system constants
constants:
# ====================================================================================
# General constants
# ====================================================================================
# [percent] - Yearly burrow fee percentage
burrow_fee_percentage: 5/1000
# [percent] - Percentage kept by the cfmm contract from the return asset
cfmm_fee: 2/1000
# [tok] - Number of collateral tokens to be given for the creation of a burrow.
# Does NOT count towards the burrow's collateral balance.
creation_deposit: 1_000_000
# [dimensionless] - Factor used for setting the liquidation limit
fliquidation: 19/10
# [dimensionless] - Factor used for setting the minting limit
fminting: 21/10
# [dimensionless?] - Maximum yearly imbalance rate
imbalance_limit: 5/100
# [dimensionless] - Factor used to scale down the imbalance rate. The higher the value, the
# faster the imbalance rate saturates.
imbalance_scaling_factor: 3/4
# [percent] - The percentage of additional collateral that we charge when liquidating a burrow
# in order to penalize it for liquidation
liquidation_penalty: 1/10
# [percent] - The percentage of a burrow's collateral that we offer to whoever triggers
# the burrow's liquidation
liquidation_reward_percentage: 1/1000
# [cNp/s] - Protected index epsilon. The higher this value is, the faster the protected
# index catches up with the actual index. Currently calculated as 0.05cNp
# per minute. Basically {[(0.05 / 100) / 60 = 5/600_000 = 1/120_000]}
# so the inverse is simply 120_000.
protected_index_inverse_epsilon: 120_000
# ====================================================================================
# Touch constants
# ====================================================================================
# The number of liquidation slices to process every time `touch` is called
number_of_slices_to_process: 5
# [kit/s] - We want the reward in the first bracket to be 0.1 kit / minute, so we just
# divide by 60 to get roughly how much should it be per second.
# See {!Checker.calculate_touch_reward} for its use.
touch_low_reward: 1/600
# [kit/s] - We want the reward in the second bracket to be 1 kit / minute, so we just
# divide by 60 to get roughly how much should it be per second.
# See {!Checker.calculate_touch_reward} for its use.
touch_high_reward: 1/60
# [s] - Parameter used for calculating the current reward for touching the checker
# contract. See {!Checker.calculate_touch_reward} for its use.
touch_reward_low_bracket: 600
# ====================================================================================
# Liquidation auction constants
# ====================================================================================
# [nP/s?] - How fast a descending option price drops per second. Currently we want it
# to drop by around 1cNp per minute, so we just divide by 60 to get roughly
# how much it should be per second.
auction_decay_rate: 1/6000
# [nP] - Every bid in an ascending auction needs to improve over the previous bid by
# at least 0.33 cNp.
bid_improvement_factor: 33/10000
# [blocks] - The maximum number of blocks that can pass between two (ascending) bids
# during an auction. The auction should expire if more blocks than this
# number pass between two bids.
max_bid_interval_in_blocks: 20
# [s] - The maximum number of seconds that can pass between two (ascending) bids
# during an auction. The auction should expire if more than this many seconds
# pass between two bids. Currently set to 20min ([20min * 60sec/min = 1200s]).

# Maximum height of the tree used as liquidation queue.
# The maximum number of elements will be between [2**(n-1)] and [2**(n-2)].
