If you are a security researcher, developer, or white hat, you can apply here to find out current details of the program and take part.
As the Sei ecosystem continues to grow, the potential for bugs and vulnerabilities can theoretically arise. The Sei Foundation takes security extremely seriously, which is why a Sei bug-bounty program has been launched in collaboration with Immunefi, the leading bug bounty and security services platform for Web3, protecting over $60 billion in user funds.
The bug bounty program incentivizes white hat hackers to report issues, helping maintain a secure and stable platform while rewarding responsible disclosure.
The bug bounty program focuses on identifying vulnerabilities in specific theoretical cases to prevent issues. The following impacts are accepted within this bug bounty program--refer to the Immune-Fi page for an official and up-to-date listing. All other impacts are considered out-of-scope and ineligible:
- Network not being able to confirm new transactions
- Unintended permanent chain split requiring hard fork
- Direct loss of funds
- Permanent freezing of funds
- Unintended chain split
- Temporary freezing of network transactions by delaying one block by 500% or more of the average block time of the preceding 24 hours beyond standard difficulty adjustments
- Causing network processing nodes to process transactions from the mempool beyond set parameters
- RPC API crash affecting projects with greater than or equal to 25% of the market capitalization on top of the respective layer
- 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
- Shutdown of greater than 10% or equal to but less than 30% of network processing nodes without brute force actions, but does not shut down the network
- Modification of transaction fees outside of design parameters
Websites and Applications
- Execute arbitrary system commands
- Retrieve sensitive data/files from a running server such as: /etc/shadow, database passwords, blockchain keys

- Subdomain takeover without already-connected wallet interaction
- 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
- Redirecting users to malicious websites
- Changing details of other users (including modifying browser local storage) without already-connected wallet interaction and with significant user interaction
- Taking over broken or expired outgoing links
- Temporarily disabling user to access target site
