- 6 of the 6 listed web3 & blockchain hackathons publish a prize pool, the largest $10,000. 1 of those is quoted in a currency other than the rupee; the card shows the organizer's own figure and the rupee value is only used to sort them into prize bands.

- How do I register for a hackathon listed here?
- Every listing here links back to the organizer's registration page — Devfolio and Unstop — and registration happens there, not on Jamao. Nothing is behind a login and no listing is paid placement. Running one? Claim your listing from its page, or add it free at jamao.in/create, and it stops being overwritten by the import.
