However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Tropykus is a decentralized lending protocol on top of Bitcoin (i.e. second layer compatible with the Ethereum Virtual Machine EVM: RSK) inspired by Compound and Aave protocols. These lending protocols provide a decentralized marketplace for suppliers and borrowers holding crypto assets.

Theft of unclaimed yield

Permanent freezing of unclaimed yield

Temporary freezing of funds

Smart contract unable to operate due to lack of token funds

Block stuffing for profit

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

Theft of gas

Unbounded gas consumption

Any governance voting result manipulation

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

Permanent freezing of funds

Miner-extractable value (MEV)

These accepted impacts are then based on the severity classification system of this bug bounty program. When submitting a bug report, please select the severity level you feel best corresponds to the severity classification system as long as the impact itself is one of the listed items.

Tropykus Smart Contracts

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.2](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. 

All Critical/High/Medium smart contract bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. All bug reports must also come with a suggestion for a fix to be considered for a reward. 

Payouts are handled by the __Tropykus__ team directly and are denominated in USD. However, payouts are done in __USD__, __USDC__, __XUSD__, __BTC__, __RBTC__ or __DOC__, at the discretion of the team.
