Captive insurance is a form of self-insurance where an entity creates a wholly-owned subsidiary to provide insurance for itself. This subsidiary, known as a "captive insurer," underwrites the risk of its parent company. Captive insurance allows the parent company to retain premiums and control the risk management process.
Due to the underlying nature of the risk, typical insurance/re-insurance carriers will not provide coverage for this type of risk.

Please read the https://forums.manifoldfinance.com/t/captive-insurance-and-fold-staking/562 forum post for more information regarding the motivations behind this mechanism.
- The parent entity provides capital to the captive insurer.
- The captive insurer collects premiums from the parent entity.
- The captive insurer provides coverage for the parent entity's risks.
- Claims are processed and paid by the captive insurer.
Caution
Disclaimer: This is not a regulated insurance product. This is a self-insurance mechanism that is designed to provide coverage for the risks associated with the Manifold Finance Relay and XGA Auction Platform.
Depositing into the FoldCaptiveStaking contract enables you to underwrite the risk of missing out on blocks due to service outages of the Manifold Finance Relay. This provides a financial safety net for validators connected to the Manifold Finance Relay.
The Relay provides Validators connected to it unique MEV opportuinities via the XGA Auction. Read more about the Auction at docs.xga.com. If the relay experiences an outage, Manifold Finance covers the cost of lost opportunities for validators that participate.
Staking $FOLD tokens transfers LP deposit ownership to the FOLDstaking contract. The contract owners can claim $FOLD balances permanently for insurance claims through the claimInsurance function.
Important
Fees earned are retained into a indemnity fund that first pays out. In the event that the losses exceed the assets in the fund, it is only then that a claim can be made against the Vault.
By underwriting the service risk of the Manifold Finance Relay and XGA Auction Platform, stakers earn yield in $ETH. $FOLD is not the reward token paid to stakers.
LPs receive rewards for staking, which includes swap fees and automated compounding of accrued fees. This incentivizes optimal compounding times concerning gas costs.
Multiple V3 positions can be deposited. The reward amount is determined by the duration and share of the total liquidity deposited in the vault, paid from the contract's WETH balance.
Withdrawals, after initiation, are pro-rated over 14 days if they exceed a certain percentage of the pool's total liquidity.
Rewards are calculated without considering the entire stake duration, instead looping through each week. Claiming rewards or removing liquidity resets the deposit's timestamp, reducing total rewards.
The reward calculation formula is as follows:
(position stake / total staked) x (stake duration / average stake duration)
Note
The Average stake duration is factored in, following the "sunshine & rainbow" design doc from Pangolin Exchange's SAR Mechanism.see docs.pangolin.exchange/faqs/understanding-sar
Depositors can choose the price range (ticks) for their UNIv3 NFT by creating it externally and calling the deposit function with DepositParams. A vote affects deposits of stakers with no personal preference, using a time-weighted median for the price range.
Uniswap automatically handles fee collection and redepositing, enhancing LP earnings. Bunni's compound function increases the value of share tokens, while FOLDstaking.sol rewards are based on deposit duration and total size across all price ranges.
Bunni pays rewards pro rata to the contribution per price range, while FOLDstaking.sol pays rewards based on deposit duration and total size relative to the pool's total liquidity across all price ranges.
We thank @ZeframLou for his tireless work on improving mechanism design in the industry.

Currently, claimInsurance does not have the logic necessary to 'validate' a claim. This is because the management of captive insurance claims is handled by us, which is why it is called Captive Insurance.
Until the L2 Construct is implemented for v2 supporting multiple relays, this is fine. However, we should outline and document how exactly a claim is substantiated. Typically, the insured party must provide notice to their insurance carrier for potential claims. Therefore, it is up to the underlying LST/Validator/Node Operator to initiate this process, it is not up to us to initialize the process for paying out a claim.
