Revest Finance proposes a new protocol for the packaging, transfer, and storage of fungible ERC-20 tokens as non-fungible tokenized financial instruments, leveraging the ERC-1155 Non-Fungible Token (NFT) standard for ease of access and universality of commerce.
Using this product, ownership of underlying assets may be traded in ways that do not affect the value of the underlying asset, leading to a new meta-layer of commerce. Discover the mechanics, governance, and monetization of this protocol with targeted use-cases.

Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
All Critical/High severity 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. In addition, Critical bug reports must also come with a suggestion for a fix in order to be considered for a reward.
The following known issues are considered to be out of scope of this program:
- All previously highlighted issues in the audit report here: https://solidity.finance/audits/Revest/
- A reentrancy vulnerability in FNFTHandler, where the active contract is currently being replaced (However, any new variations of attacks that can be executed on the new active contract would still be considered as in scope).
- A known vulnerability in TokenVault within the “handleMultipleDeposits” method. This is understood, documented, and will never be called by live code.
- Any bugs relating to vulnerabilities in their oracles and the UniswapV3 oracle full coverage problem (Impacted oracles are currently disabled from their UI). Vulnerability is understood to never lead to theft-of-value, only early-unlocks.
Rewards for critical smart contract vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum reward of USD 50 000 for Critical smart contract bug reports.
Critical website and application bug reports will be rewarded with USD 30 000 only if the impact leads to a direct loss in funds or a manipulation of the votes or the voting result, as well as the modification of its display leading to a misrepresentation of the result or vote. All other impacts that would be classified as Critical would be rewarded no more than USD 10 000.
Payouts are handled by the Revest team directly and are denominated in USD. However, payouts are done in USDC.

All smart contracts of Revest can be found at https://github.com/Revest-Finance/RevestContracts. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.
If any Critical or High severity impact can be caused to any other asset managed by Revest that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project.
Impacts in scope
Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.
