Parameter catalog

Every governable on-chain parameter, with its default, absolute range, and per-cycle rate limit. Names match the IDs exposed by the supervisory contracts (PoolSupervised, PositionSupervised, OracleSupervised, VaultSupervised).

Pool parameters (per token)

Parameter	Default	Range	Per cycle	Notes
MAX_SUPPLY	1 week	1s – 1y	0.5×–2×	Supply rate-limit ceiling
MIN_SUPPLY	1 day	1s – 1y	0.5×–2×	Supply rate-limit floor
POW_SUPPLY	per token	0–64	0.5×–2×	PoW difficulty for permissionless supply
MAX_BORROW	1 week	1s – 1y	0.5×–2×	Borrow rate-limit ceiling
MIN_BORROW	1 day	1s – 1y	0.5×–2×	Borrow rate-limit floor
POW_BORROW	per token	0–64	0.5×–2×	PoW difficulty for permissionless borrow
POW_SQUARE	per partial_exp	0–64	0.5×–2×	PoW difficulty for permissionless liquidate
WEIGHT_SUPPLY	170	0–255	0.5×–2×	Supply-side weight in the health calculation
WEIGHT_BORROW	255	0–255	0.5×–2×	Borrow-side weight in the health calculation

The effective LTV emerges from the default ratio of WEIGHT_SUPPLY / WEIGHT_BORROW = 170/255 ≈ 66.67%. Similarly, the effective supply (or borrow) rate-limit emerges from the default ratio of MAX_SUPPLY / MIN_SUPPLY = 1w/1d = 7 (or MAX_BORROW / MIN_BORROW); i.e. the supply (or borrow) frequency is rate-limited to at most seven actions in a week — per account.

Position parameters

Parameter	Default	Range	Per cycle	Notes
CAP	per pool	0 – 2¹¹²	0 – 2¹¹²	Cap limit
UTIL	90%	0 – <100%	0.5×–2×	Target utilisation
RATE	10%	0 – <100%	0.5×–2×	Target interest rate at UTIL
SPREAD	10%	0 – 50%	0.5×–2×	Half-spread between supply and borrow APR
MIN_HOLDERS	per pool	0 – MIN_HOLDERS	0.5×–2×	Minimum holder threshold
LOCK_BONUS	10%	0 – SPREAD	0.5×–2×	Supply-rate increase for full lock
LOCK_MALUS	10%	0 – SPREAD	0.5×–2×	Borrow-rate decrease for full lock

Note, that CAP target management is not subject to the usual per cycle change limits in the range of 0.5×–2×! Further, while the actual cap value approaches an arbitrarily increased target asymptotically, a decreased target below the current cap value is applied immediately — which can act as a circuit breaker.

Vault parameters

Parameter	Default	Range	Per cycle	Notes
FEE_ENTRY	0.1%	0 – 50%	0.5×–2×	Skim on depositAssets
FEE_EXIT	1.0%	0 – 50%	0.5×–2×	Skim on redeemAssets

Oracle parameters

Parameter	Default	Range	Per cycle	Notes
DECAY	0.944	0.5 – 1.0	0.5×–2×	EWMA decay (the α in the math); 12-hour half-life at LIMIT = 1h
DELAY	14 days	1w – 3m	0.5×–2×	Delay before a newly-enlisted feed becomes live
LEVEL	per feed	0 – 64	0.5×–2×	PoW difficulty for permissionless retwap
LIMIT	1 hour	1s – 1d	0.5×–2×	Minimum spacing between two TWAP refreshes

Per-call arguments (not parameters)

Some quantities the documentation calls out are call arguments, not stored parameters:

• partial_exp — passed to liquidate(victim, partial_exp). Slice = 2^-partial_exp of the position. POW_SQUARE is the parameter that gates difficulty per-partial_exp.
