    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Any wallet's profit and loss on Base, from public chain data. Wallet: its stock tokens since 1 Oct 2026, average cost from the wallet's own USDC trades on any venue (DEX or orderbook), realised and unrealised per token; transfers are never priced. Strategies: one row per strategy (live and cancelled orders it placed, incl. its RiverAccount): fills, USDC spent and received, tokens bought and sold, and P&L at today's prices (value now minus what was put in). Robinhood Chain is not counted yet (stated in notes).

    Why it is in this group

    • The name "compare_issuers" says "compare": a word for reading.
    Description, as the server wrote it
    Where a tokenized stock is cheapest: each issuer's token (ST0x, Coinbase, Robinhood) priced per share for a $100 buy, against the stock's own price (US, or the home exchange's in dollars), with the gap in % and the lowest issuer. From quotes taken every 5 minutes (biggest stocks) or hourly; the time is in the answer. Not a live quote: for an executable best-price buy use trade_link with usd. Up to 12 tickers.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
