Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.3. 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.
Medium and low smart contract bug reports must come with a PoC in order to be considered for a reward.
Critical smart contract vulnerabilities are paid at 10% of economic damage, primarily based on funds at risk. The team may, at its discretion, take into consideration other aspects such as PR and branding effects. However, there is a minimum reward of USD 50 000.
KYC
Notional rewards both foreigners and USA nationals:
- Foreigners must complete the W-8BEN, which is IRS mandated
- USA nationals must complete the W9
Payouts are handled by the Notional team directly and are denominated in USD. However, payouts are done in USDC, DAI, ETH, USDT, or the project token, at the discretion of the team.
Program Overview
Notional is a protocol on Ethereum that facilitates fixed-rate, fixed-term crypto asset lending and borrowing through a novel financial instrument called fCash.
fCash is a tokenized representation of a fCash flow. It represents the amount of tokens (i.e. Dai) that an account is either entitled to receive or obligated to pay at its designated maturity. For example, if an account holds +100 fCash tokens for a maturity on January 1, 2021, it is entitled to 100 Dai at any time greater than or equal to January 1, 2021. Similarly, -100 fCash tokens for the same maturity means that the account is obligated to pay 100 Dai at maturity.

This bug bounty program is focused on their smart contracts and app and is focused on preventing the following impacts:
- Loss of funds
- Voting manipulation
- Any function that is outside the intended behavior of the smart contracts
- Redirection of funds
- Injection of text
KYC required
The submission of KYC information is a requirement for payout processing.
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.
