Nuggies

Nuggies is a DeFi project currently in alpha with an autocompounding vault. Currently, they have this feature available for ALCX.

For more information about Nuggies, please visit https://www.nuggies.fi/.

The bug bounty program covers its smart contracts and is focused on preventing the following impacts:

• Thefts and freezing of principal of any amount
• Thefts and freezing of unclaimed yield 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 must come with a PoC.

The team is aware of cases where the strategist fee /or gas fee is changed while there are pending rewards, resulting in the pending rewards potentially not being divided perfectly. This is out of scope of the bug bounty program as this can be mitigated by always changing fees when harvest is called.

Payouts are handled by the Nuggies team directly and are denominated in USD. Payouts are done in ETH.

All contracts can be found at https://github.com/nuggiesfinance/platform. However, only the contracts listed in the table are counted as within the scope of the bug bounty program.

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 Unable to call smart contract Smart contract fails to deliver promised returns Smart contract gas drainage Temporary freezing of funds of any amount of time

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
