A LITTLE MORE CONTEXT
Good questions.
Clear answers.
What does verification mean?
B20 Stocks matches a token contract to the supported registry and checks available market and execution evidence. It reduces impersonation and routing risk; it does not remove market risk or make a trade safe.
Can I swap when the stock market is closed?
DEX markets operate around the clock. A traditional-market reference may be delayed or closed, while a Base DEX quote remains the execution price. Both are shown separately when available.
How are verified routes ranked?
For the exact input amount, eligible executable routes are ranked by minimum received. If coverage is partial or only one route is available, the swap review says so instead of implying a broader comparison.
Who controls my funds?
You do. B20 Stocks never holds funds, private keys, or seed phrases. You confirm each exact-amount approval and transaction in your own wallet on the Verified Swap page.
