# Instructions to invest on Kroma's blockchain

To be eligible to participate in the Sentinel Token private round on Kroma's blockchain, you need either to own a MemPass NFT of any grade on Kroma or to have been manually whitelisted. Manual whitelisting of 3,000 individuals has already occurred, and no further manual whitelisting will take place.

To purchase a MemPass NFT, visit the Rarible NFT secondary marketplace and acquire any MemPass NFT.
