Kiln V1 Bounty
@kilnfi
LiveKiln On-Chain (v1) enables non-custodial platforms to propose an ETH staking offer where users can stake on dedicated validators while remaining the only one able to access their staked assets. The goal of these Ethereum Smart Contracts is to enable:
- Operator to register its validation keys deposit data on the Smart Contract
- Users to deposit on approved and available validation keys
- Manage the Execution and Consensus Layer rewards and exited ETH
- Perform the commission dispatching on these ETH when user performs a withdrawal action
This Bug Bounty is focused on the Staking Smart Contracts only, all items regarding dApps or validation infrastructure are out of scope.
For more information about Kiln On-Chain, please visit https://www.kiln.fi/ Kiln provides rewards in USDC. For more details about the payment process, please view the Rewards & Severity Levels below

Severity Definitions
Smart Contracts severity levels
| Severity level | Impact: High | Impact: Medium | Impact: Low |
|---|---|---|---|
| Likelihood:high | Critical | High | Medium |
| Likelihood:medium | High | Medium | - |
| Likelihood:low | Medium | - | - |
Critical: - Complete loss of funds or permanent freezing of funds
High: - Theft of unclaimed yield, commission/fees or Permanent freezing of unclaimed yield - Temporary freezing of funds > 2 days (excluding potential delay due to an oracle).
Medium: - Smart contracts inoperable due to lack of funds - Griefing or unbounded gas consumption
A PoC is required for the following severity levels:
- Smart Contract:
- Critical
- High
- Medium
Rewards
Rewards for Smart Contract Bugs
| Severity | Reward Amount |
|---|---|
| Critical | $1,000,000 |
| High | $100,000 |
| Medium | $20,000 |
Reward Levels
-
Critical: Upto 1,000,000, Minumum payout 100,000 Rewards will be further capped at 10% of direct funds at risk based on the valid POC provided
-
High: Upto 100,000, Minimum payout 20,000 Rewards will be further capped at 100% of direct funds at risk based on the valid POC provided. In case of a temporary freeze of funds, reward is proportional to the amount of funds locked and increases as the freeze duration increases up until the maximum cap of the High severity levels.
-
Medium: Upto 20,000, Minimum payout $5,000 Rewards will be further capped at 100% of direct funds at risk based on the valid POC provided.
-
The bug bounty will have a hard cap of $1,500,000. In the case of multiple bug findings are submitted that exceed this amount, the rewards will be distributed on a first come first served basis.
Out of Scope
These impacts are out of scope for this bug bounty program. General:
- Consequences resulting from exploits the reporter has already carried out, which lead to damage.
- Issues caused by attacks that require access to leaked keys or credentials.
- Problems arising from attacks that need access to privileged roles (e.g., governance or strategist), except when the contracts are explicitly designed to prevent privileged access to functions that enable the attack.
- Issues relying on attacks triggered by the depegging of an external stablecoin, unless the attacker causes the depegging due to a bug in the code.
- References to secrets, access tokens, API keys, private keys, etc., that are not being used in production.
Smart Contracts:
- Issues arising from incorrect data provided by third-party oracles, with the exception of oracle manipulation or flash loan attacks.
- Attacks that rely on basic economic or governance vulnerabilities, such as a 51% attack.
- Problems related to insufficient liquidity.
- Issues stemming from Sybil attacks.
- Concerns involving risks of centralization.
- Suggestions for best practices.
Roles:
- Operator, Admin and Proxy Admin are trusted to behave properly and in the best interest of the users. They should not be considered as malicious. Submission citing malicious behaviour of these roles will be considered invalid.
Known Issues
Known issues listed and acknowledged below are not eligible for any reward through the bug bounty program.
Specific Types of Issues
- Informational findings.
- Design choices related to protocol.
- Issues that are ultimately user errors and can easily be caught in the frontend. For example, transfers to
address(0). - Rounding errors.
- Relatively high gas consumption.
- Extreme market turmoil vulnerability.
Disclosure
Researchers who submit valid vulnerability reports agree to adhere to the following responsible disclosure process:
- Upon confirmation of a valid vulnerability, Kiln will work diligently to develop and implement a fix.
- Once the fix is deployed to production, Kiln will notify the researcher and initiate a 1-month (30 calendar days) disclosure waiting period.
- During this waiting period, the researcher must maintain strict confidentiality regarding the vulnerability and shall not disclose any information about it to third parties or the public.
- After the 1-month period has elapsed following the production deployment of the fix, the researcher may publicly disclose the vulnerability, provided they have obtained written approval from Kiln regarding the content of the disclosure.
- The researcher agrees to coordinate with Kiln on the timing and content of any public disclosure to ensure all parties are prepared and to minimize potential risks to users.
- If the researcher discovers that the vulnerability has become publicly known before the end of the waiting period, they should immediately notify Kiln. Kiln reserves the right to request an extension of the waiting period in exceptional circumstances, which will be communicated to the researcher in writing.
KYC
