Critical Reward Calculation

Mainnet assets:

Reward amount is 10% of the funds directly affected up to a maximum of:

$100,000

Rewards for Smart Contract vulnerabilities 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 and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

The amount of funds at risk affects the final severity classification of the bug report. A vulnerability resulting in the direct loss of protocol funds of 10% or greater remains classified as Critical. However, they are reclassified as High if the impact is less than 10% but greater than 0.1%. If the impact is less than 0.1%, they are reclassified as Medium.

Bug reports are required to include a complete issue description and instructions to reproduce the issue or a PoC. Reports that include a solution to fix the problem have a higher likelihood of receiving the full reward under the respective severity classification tier.

The final reward is determined at the sole discretion of the Alpaca Finance team.

Payouts are handled by the Alpaca Finance team directly and are denominated in USD. However, payouts are done in USDT.

Program Overview

Alpaca Finance is the largest lending protocol allowing leveraged yield farming on Binance Smart Chain. It helps lenders to earn safe and stable yields, and offers borrowers undercollateralized loans for leveraged yield farming positions, vastly multiplying their farming principals and resulting profits.

Furthermore, Alpacas are a virtuous breed. That’s why, Alpaca is a fair-launch project with no pre-sale, no investor, and no pre-mine. So from the beginning, it has always been a product built by the people, for the people. Or as they like to say: by the Alpacas, for the Alpacas.

More information about Alpaca Finance can be found on their website, https://www.alpacafinance.org/.

This bug bounty program is focused around its smart contracts and is mostly concerned with the prevention of the loss of user funds.

No KYC information is required for payout processing.

Proof of Concept

Proof of concept is always required for all severities.

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.
