Coinbase stock (COIN) has a tokenised version, COINx, a blockchain based asset that represents Coinbase Global shares. Each COINx token is backed 1:1 by real Coinbase shares held in regulated custody. Coinbase is a cryptocurrency platform that lets people buy, sell, store and stake digital assets, and it also serves institutions with trading and custody. Founded in 2012, it became a public company on Nasdaq in 2021 and supports the Base layer 2 network. Because its revenue is linked to crypto trading activity, its share price often moves with the crypto market. Holding COINx gives you indirect exposure to Coinbase shares, but it is not the same as owning the underlying shares and does not come with shareholder rights.
