Immunefi Bug Bounty
Immunefi is the leading bug bounty and security services platform for Web3, guarding over $25 billion in user funds across crypto projects. Immunefi hosts bug bounties for blockchain projects across all chains and networks by providing a forum bringing builders and hackers together, enabling hackers to report bugs privately and responsibly for projects to fix vulnerabilities securely.
- Websites and Applications (App Frontend): live since 21 February 2023
- Smart Contracts: live since 10 May 2023
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 bug reports must come with a Proof-of-Concept (PoC) and an end-effect that impacts an Asset in Scope to be considered for a reward. Bug reports must include an executable PoC in order to prove the impact. Exceptions may be made in cases where the vulnerability is objectively evident by simply mentioning its existence and location. Though please note, in such a case, the bug reporter may be required to provide a PoC at any point in time.
Smart Contract
Level | Payout (Up To) | PoC Required |
|---|---|---|
Critical | USD $1,000,000 | ✅ |
High | USD $25,000 | ✅ |
Medium | USD $10,000 | ✅ |
Websites and Applications
Level | Payout | PoC Required |
|---|---|---|
Critical | USD $10,000 | ✅ |
High | USD $5,000 | ✅ |
Medium | USD $2,000 | ✅ |
Payouts are handled by the LEVEL team directly and are denominated in USD, but payouts are distributed in LVL tokens. The bug bounty program has the following hard caps:
- Smart Contracts: $1,000,000
- Websites and Applications: $10,000
In the event that multiple bug reports are submitted that exceed this amount, the rewards will be provided on a first come first served basis.

Websites and Applications
Target | Type |
|---|---|
https://app.level.finance/ | Websites and Applications - App frontend |
The entire LEVEL codebase can be found at https://github.com/level-fi. The scope of this bug bounty program is restricted to Assets in Scope, shown above.
For reference purposes, the public testnet can be found at https://test.level.finance/. Please note, program rules prohibit testing on the public testnet.
In the case that an impact is found that does not fit into the Assets in Scope but can be found below in the Impacts in Scope, you are encouraged to submit it for consideration by the team.
Only the following impacts are accepted within this bug bounty program. All other impacts are not considered in-scope, even if they affect something in the Assets in Scope.
Smart Contract
Impact | Level |
|---|---|
Theft of governance funds | Critical |
Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield | Critical |
Loss of user funds by freezing, theft, or manipulation of the price of LLP | Critical |
Permanent freezing of funds | Critical |
Protocol Insolvency | Critical |
Theft of unclaimed yield | High |
Permanent freezing of unclaimed yield | High |
Block stuffing for profit | Medium |
Griefing (e.g. no profit for an attacker but damage to the users or the protocol) | Medium |
Websites and Applications
Impact | Level |
|---|---|
Execute arbitrary system commands | Critical |
Retrieve sensitive data/files from a running server such as /etc/shadow, database passwords, and blockchain keys (this does not include non-sensitive environment variables, open source code, or usernames) | Critical |
Taking down the application/website | Critical |
Taking state-modifying authenticated actions (with or without blockchain state interaction) on behalf of other users without any interaction by that user, such as changing registration information, commenting, voting, making trades, withdrawals, etc. | Critical |
Subdomain takeover with already-connected wallet interaction | Critical |
Direct theft of user funds | Critical |
Malicious interactions with an already-connected wallet such as modifying transaction arguments or parameters, substituting contract addresses, submitting malicious transactions | Critical |
Injecting/modifying the static content on the target application without Javascript (Persistent) such as HTML injection without Javascript, replacing existing text with arbitrary text, arbitrary file uploads, etc. | High |
Changing sensitive details of other users (including modifying browser local storage) without already-connected wallet interaction and with up to one click of user interaction, such as email or password of the victim, etc. | High |
Subdomain takeover without already-connected wallet interaction | High |
Changing non-sensitive details of other users (including modifying browser local storage) without already-connected wallet interaction and with up to one click of user interaction, such as changing the first/last name of user, or en/disabling notification | Medium |
Injecting/modifying the static content on the target application without Javascript (Reflected) such as reflected HTML injection or loading external site data | Medium |
Redirecting users to malicious websites (Open Redirect) | Medium |
The following vulnerabilities are excluded from the rewards of this bug bounty program:
All Categories

- Attacks requiring access to leaked keys/credentials
- Attacks requiring access to privileged addresses (governance, strategist), except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
- Broken link hijacking is out of scope
Smart Contracts and Blockchain/DLT
- Basic economic governance attacks (e.g. 51% attack)
- Lack of liquidity
- Best practice critiques
- Sybil attacks
- Centralization risks
Websites and Applications

httponly”) without demonstration of impact - Server-side non-confidential information disclosure such as IPs, server names, and most stack traces
- Vulnerabilities used only to enumerate or confirm the existence of users or tenants
- Vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
