Capital & Leverage

How syndicate capital, risk points, and leverage controls work

TL;DR: Syndicates back pools with single-sided capital. Exposure is governed by a 20-point risk budget, mutex exclusivity, and a concentration-based leverage ladder. At launch, the configured max leverage is 3x.

Single-Sided Liquidity

Underwriters participate by depositing a single asset (e.g., USDC) into the CapitalPool. There's no LP pairing, no governance token requirement, and no impermanent loss.

  • Asset choice - Deposit USDC (or wstETH on the LST instance)
  • External yield - Idle capital (not backing active claims) earns DeFi yield via whitelisted adapters (Aave, Compound)
  • Full withdrawal - Get back your principal + earned premiums + yield, minus any claim losses

Capital Pledges

When you allocate capital to a pool, you create a pledge - a commitment to back policies sold from that pool.


  • Total pledges can exceed your deposit when the syndicate remains inside the risk budget and leverage ladder
  • There is no live fixed per-pool concentration cap in the current underwriting model
  • Your capital can be pledged across multiple pools simultaneously, subject to mutex and pool-specific caps
  • Pledges can be adjusted as pools change or as you rebalance

Risk Points

Each pool has a risk point cost based on its rating. Lower-rated pools consume more of the syndicate's point budget per dollar of pledged capital.

Risk Point Costs

When a syndicate allocates to a pool, points used scale with both the pool's rating and the size of the pledge relative to syndicate principal.

Live Formula
Points Used = Point Cost × (Pledge Amount / Syndicate Principal)

Larger allocations and weaker ratings both push the total higher. Across all pledges, the sum must stay at or below 20.

Lower-rated pools spend budget faster

Every allocation draws from the same 20-point underwriting budget. Safer pools leave more room to diversify; weaker ratings consume capacity more aggressively.

Budget Rules

Points used scale linearly with both the rating cost and the share of syndicate principal committed to a pool. A book can stay diversified only if it preserves room under the cap.

Total Risk Budget
20 points

Across all active pledges, total point usage must remain at or below this threshold.

AAA and AA

Most flexible for spreading capital across multiple pools.

Watch closely
BBB and below

Budget burns faster and leverage headroom narrows quickly.

Important caveat
Points are not the only limit

Concentration can still reduce leverage before the point budget is full.


Leverage Ladder

Risk points are only one side of the limit. The other side is the largest single-pool share in the syndicate. As concentration rises, the protocol reduces effective leverage.

At launch, governance intends to configure the syndicate max leverage at 3x, and the live leverage ceiling is the lower of:

  • the configured max leverage ratio
  • the concentration ladder derived from the syndicate's largest pledge

Concentration Bands

Largest Single-Pool Share of PrincipalEffective Max Leverage
0% - 15%3.0x
15% - 30%scales from 3.0x down to 2.5x
30% - 50%scales from 2.5x down to 2.0x
50% - 70%scales from 2.0x down to 1.5x
70% - 100%scales from 1.5x down to 1.0x

That means the protocol no longer uses a fixed per-pool cap or override model. Concentration is handled directly by the leverage ladder instead.

Worked Example

You deposit 100,000 USDC and allocate:

AllocationPool RatingPoint CostPoints Used
$40K → Aave USDCAAA1 × (40/100) = 0.40.4
$35K → Compound cDAIAA2 × (35/100) = 0.70.7
$25K → Vault Protocol XA3 × (25/100) = 0.750.75
$20K → Yield Farm YBBB4 × (20/100) = 0.80.8
$120K total pledge2.65 / 20 used

This book is at 1.2x leverage, uses 2.65 / 20 points, and its largest pool is 40% of principal. At that concentration, the leverage ladder still permits more total pledge than 1.2x, so the syndicate is comfortably inside both constraints.

Largest Pool Share

Leverage means concentration still matters. Low point usage does not guarantee spare capacity if one pool grows too large. The concentration ladder can become the binding limit before the point budget is exhausted.


Mutex Groups

Pools that cover correlated risks are grouped into mutex (mutual exclusion) groups. A syndicate cannot allocate to more than one pool in the same mutex group at the same time.


This is stricter than the legacy docs model. Correlated pools do not get a blended surcharge; the second conflicting allocation is rejected outright.


Capital Adequacy Ratio

Syndicates must maintain a minimum 50% capital adequacy ratio to write new business. This means the syndicate's principal must be at least 50% of its total pledged exposure.

If losses erode a syndicate's principal below this threshold, the protocol blocks new intent reservations (quoting) until the ratio recovers — either through new deposits or pledge reductions.

Solvency gating. This mirrors Lloyd's Solvency Capital Requirement (SCR). Syndicates below the threshold can still manage existing policies and process claims, but cannot take on new risk until recapitalized.


Premium Distribution

When policyholders pay premiums, the gross premium is split as follows:


  • Referral reward is 5% when a valid referral code is used, otherwise this slice stays with the underwriter
  • Protocol fee is 10%
  • Backstop premium is 20%
  • Underwriter premium receives the remainder: 65% with a referral, or 70% without one

So the live underwriting economics are a fixed split of gross premium, with only the referral portion being conditional on whether a valid referral code was attached.
