Only Senior Best Yield contracts will be considered in scope. Governance and Utilities and ERC-4626 wrappers contracts are not covered under this bug bounty program. Paused contracts are not considered in scope.

Idle is a decentralized protocol dedicated to bringing automatic asset allocation and aggregation to the interest-bearing tokens economy. This protocol bundles stable crypto-assets (stablecoins) into tokenized baskets that are programmed to automatically rebalance based on different management logics.

Theft of unclaimed yield

Permanent freezing of unclaimed yield

Smart contract unable to operate due to lack of token funds

Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)

Temporary freezing of funds

Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield

Permanent freezing of funds

Miner-extractable value (MEV) if can freeze funds or cause protocol insolvency

Protocol insolvency

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System 2.2](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-2/). This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit. 

The final reward for critical bounty payouts is capped at 10% of the funds at risk based on the vulnerability reported.

PoC is required for all levels.

Theft of yield or interest is considered as Medium but may be considered High depending on the amount of funds at risk.

Best practices critiques are not accepted under this program. 

The likelihood of exploitability is also taken into consideration in the
determination of the final payout amount based on the severity of the bug
reported according to the table below:

| | Medium | High | Critical |
|  :-- | :-- | :-- | :-: |
| Almost Certain | $5,000 | $20,000 | $50,000 |
| Likely | $3,000 | $10,000 | $25,000 | 
| Possible | $1,000 | $5,000 | $10,000 |
| Unlikely  | $500 | $1,000 | $5,000 |
| Almost Possible | $100 | $500 | $1,000 |

Payouts are handled by **Idle Finance** governance directly and are denominated
in **USD**. Payouts under $10,000 are done in **USDC**. When payouts are over
$10,000, the first $10,000 is paid in **USDC** and then the rest are paid in
**IDLE** up to the total of $50 000.
