Impacts in Scope
Network not being able to confirm new transactions (total network shutdown)
Unintended permanent chain split requiring hard fork (network partition requiring hard fork)
Direct loss of funds
Permanent freezing of funds (fix requires hardfork)
Unintended chain split (network partition)
Causing network processing nodes to process transactions from the mempool beyond set parameters
RPC API crash affecting programs with greater than or equal to 25% of the market capitalization on top of the respective layer
Temporary freezing of network transactions by reducing number of blocks produced in an hour to be less than 60. I.e. average block time > 60s.
Increasing network processing node resource consumption by at least 30% without brute force actions, compared to the preceding 24 hours
Shutdown of greater than or equal to 30% of network processing nodes without brute force actions, but does not shut down the network
A bug in the respective layer 0/1/2 network code that results in unintended smart contract behavior with no concrete funds at direct risk
Out of scope
Blockchain/DLT specific
- Incorrect data supplied by third party oracles
- Not to exclude oracle manipulation/flash loan attacks
- Impacts requiring basic economic and governance attacks (e.g. 51% attack)
- Lack of liquidity impacts
- Impacts from Sybil attacks
- Impacts involving centralization risks
All categories
- Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
- Impacts caused by attacks requiring access to leaked keys/credentials
- Impacts caused by attacks requiring access to privileged addresses (including, but not limited to: governance and strategist contracts) without additional modifications to the privileges attributed
- Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
- Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
- Best practice recommendations
- Feature requests
- Impacts on test files and configuration files unless stated otherwise in the bug bounty program
- Impacts requiring phishing or other social engineering attacks against project's employees and/or customers
