According to The Defiant, the on-chain insurance protocol Firelight based on the Flare network announced on October 15 that its on-chain insurance has launched the Protected Strategies USDC vault for Kraken DeFi Earn, providing a collateral-backed compensation mechanism for specific protocol failures.The independent manager of the vault, Sentora, insures the vault rather than Kraken itself. Depositors do not need to actively choose to participate, but the insurance comes with conditions: Kraken discloses that the compensation limit for each deposit address during each insurance period is $100,000, and the total compensation amount is also constrained by the overall vault limit and available capital. Compensation is issued by Sentora in USDC to eligible wallets, and Kraken does not provide funds or guarantees.Firelight lists six types of failures that are eligible for compensation: smart contract vulnerabilities, oracle failures, governance attacks, and bad debts, depegging, or redemption failures caused by protocol mechanism failures. Insurance only applies to markets and positions recorded during the insurance period. Normal fluctuations, normal liquidations, depegging that operates as designed during redemption, and withdrawal delays caused by high organic utilization are excluded; insider theft, stolen private keys, phishing, and regulatory actions are also not covered.The trigger conditions for redemption failure are if the insured position cannot be withdrawn for more than 72 consecutive hours, or if the amount returned after deducting disclosed fees is less than 90% of fair value. Compensation does not require depositors to file claims themselves, as it is determined by a five-member risk committee through a three-fifths majority vote.On-chain records show that the insurance scale marked as "Kraken DeFi Protected" is $30.5 million.
