Vlad's right that self-custody is the real unlock. Portability gets the headlines, but the interesting part is what you can do with an asset once it's actually in your wallet.
The obvious thing is borrow against it. That's how every mature asset class works - you own something, you can raise cash against it without selling it. Stock Tokens have been missing that layer, and it's not because nobody wants it.
So we built it. Arrow: deposit AAPL, NVDA, TSLA, SPY, PLTR - 24 markets - mint aUSD against them, keep the shares.
On Robinhood Chain, where they already live. Mainnet soon.
