Etherscan published a guide to understanding tokenized stocks amid the recent surge in RWA tokenization. Etherscan notes that most stock tokens do not provide ownership of the underlying share, but rather economic exposure to its price akin to a derivative. Examples include Ondo and xStocks, which together issue over 500 tokens. Backpack offers tokens redeemable 1:1 for real shares.
On Etherscan, stock tokens have the same ERC-20 explorer pages as any other token. Some tokens have a logo, issuer website, and reputation checkmark. Etherscan also lists the holder concentration and Gini score; transfer heatmaps showing 24/7 weekend activity; and the verified source contract, including the implementation contract if the token uses a proxy pattern. There's also issues with confusion among assets with hundreds of tokens using the same stock ticker.
One framework worth keeping in mind is that strong onchain mechanics and strong legal structure are two separate axes. A token with transparent contracts, timelocks, and clean redemption queues can still rest on a thin legal claim, subordinated debt against an operating company rather than a ring-fenced vehicle. The chain tells how the token behaves. However, the offering documents states what it actually is and if there's a real claim on the underlying stock.
