Burrow

Burrow is a decentralized, non-custodial pool-based interest rates platform that enables users to supply assets to earn interest, and to borrow against them to unlock liquidity. Burrow is similar in nature to Aave, Compound, and other pool-based protocols. Burrow runs natively on the NEAR blockchain, a layer 1, proof-of-stake, sharded blockchain with a WebAssembly runtime.

Rewards by Threat Level

Smart Contract
Critical
USD $25,000 to USD $250,000
High
USD $5,000 to USD $25,000
Medium
USD $1,000 to USD $5,000
Low
USD $1,000

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, and Medium 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, all bug reports must come with a suggestion for a fix in order to be considered for a reward.

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 25 000 for Critical smart contract bug reports.

High smart contract vulnerabilities are capped at 10% of economic damage, primarily based on value at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward for high vulnerabilities of USD 5 000.

Medium smart contract vulnerabilities are capped at 10% of economic damage, primarily based on value at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward for medium vulnerabilities of USD 1 000.

Known issues highlighted in the following audit reports are considered out of scope:

Burrow requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. For individuals, the information needed is proof of address and government-issued photo ID for each authorized representative. For companies, the requirements will vary based on the type of the entity. Payouts are handled by the Burrow team directly and are denominated in USD. However, payouts are done in USDC or USDT.

Program Overview

Burrow is a decentralized, non-custodial pool-based interest rates platform that enables users to supply assets to earn interest, and to borrow against them to unlock liquidity. Burrow is similar in nature to Aave, Compound, and other pool-based protocols. Burrow runs natively on the NEAR blockchain, a layer 1, proof-of-stake, sharded blockchain with a WebAssembly runtime. The Burrow protocol's smart contracts are written in Rust.

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.
