Beta Finance

Beta Finance is the permissionless money market for borrowing, lending, and shorting crypto assets. This means that anyone at any time is able to create a money market for any crypto asset. Their mission is to offset the volatility in DeFi today by developing critical infrastructure and user tooling to facilitate market efficiency. They stand by the DeFi ethos of "Open Finance For All" and seek to re-define finance by providing a foundational block in DeFi that future projects will be built upon.

The bug bounty program covers its smart contracts and is focused on preventing thefts and freezing of principal of any amount.

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. 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.

Critical bug reports are further capped at 10% of economic damage, primarily based on funds at risk, though considerations may be given to PR and branding effects, at the discretion of the team.

Payouts are handled by the Beta Finance team directly and are denominated in USD. Payouts are done in USDT.

For further reference, all other BTokens can be tracked on Create method here: https://etherscan.io/address/0x38a466b5c0f1d09918fc8e795945bf3ad32d0080

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.

Smart Contracts

• Loss of user funds staked (principal) by freezing or theft
• Theft of unclaimed yield
• Freezing of unclaimed yield
• Temporary freezing of funds for at least 1 hour

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts and Blockchain

• Re-entrancy
• Logic errors
  • including user authentication errors
• Solidity/EVM details not considered
  • including integer over-/under-flow
  • including rounding errors
  • including unhandled exceptions
• Trusting trust/dependency vulnerabilities
  • including composability vulnerabilities
• Oracle failure/manipulation
• Novel governance attacks
• Economic/financial attacks
  • including flash loan attacks
• Congestion and scalability
  • including running out of gas
  • including block stuffing
  • including susceptibility to frontrunning
• Consensus failures
• Cryptography problems
  • Signature malleability
  • Susceptibility to replay attacks
  • Weak randomness
  • Weak encryption
• Susceptibility to block timestamp manipulation
• Missing access controls / unprotected internal or debugging interfaces

The following vulnerabilities are excluded from the rewards for this bug bounty program:

• Attacks that the reporter has already exploited themselves, leading to damage
• Attacks requiring access to leaked keys/credentials
• Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Basic economic governance attacks (e.g. 51% attack)
• Lack of liquidity
• Best practice critiques
• Sybil attacks

The following activities are prohibited by this bug bounty program:

• Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
• 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
• Automated testing of services that generates significant amounts of traffic
• Public disclosure of an unpatched vulnerability in an embargoed bounty
