    Rewards are distributed among SRs according to Immunefi’s Standardized Competition Reward Terms and includes All Star Pool and Podium Pool reserved for All Star Program participants.

    Rewards are denominated in USD and distributed in USDC on Ethereum.

    Flat Rewards: The reward pool is $30,000 USD if any bug is found. That means that even if 1 Low severity bug is found, the whole reward pool is unlocked and has to be fully distributed between security researchers.

    If not a single bug is found (Insights do not count as bugs) the reward pool is $4,500 USD. Private known issues, meaning known issues that were not publicly disclosed, are valid and unlock the corresponding reward pool.

    Proof of Concept (PoC) Requirements A runnable PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and Rules.

    Program Overview

    Folks Finance is a leading DeFi platform providing innovative tools for lending, borrowing, trading and managing digital assets, all in one place.

    Folks Finance has built an implementation of Wormhole’s Native Token Transfers (NTT) for Algorand. Wormhole NTT is a framework for transferring tokens across blockchains without liquidity pools. Unlike traditional wrapped assets, NTT maintains your token's native properties on every chain. This ensures that you retain complete control over crucial aspects, such as metadata, ownership, upgradeability, and custom features.

    Responsible Publication

    Category 3: Approval Required

    Prohibited Activities

    Default prohibited activities
    • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
    • Any testing with pricing oracles or third-party smart contracts
    • Attempting phishing or other social engineering attacks against our employees and/or customers
    • Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
    • Any denial of service attacks that are executed against project assets
    • Automated testing of services that generates significant amounts of traffic
    • Public disclosure of an unpatched vulnerability in an embargoed bounty
    • Any other actions prohibited by the Immunefi Rules

    Feasibility Limitations

    The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

    Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
