  • execute_onchain_swapExecute a REAL on-chain swap on Robinhood Chain via the Rialto router, signed by Otto's server-side trading wallet.No findings

    Why it is in this group

    • The name "execute_onchain_swap" says "execute": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Execute a REAL on-chain swap on Robinhood Chain via the Rialto router, signed by Otto's server-side trading wallet. side=buy spends `usd_amount` USDG to buy the ticker's Hood token; side=sell sells `qty` tokens back to USDG. The server enforces hard guardrails independently of the caller: USDG<->allowlisted-token pairs only, per-trade and daily USD caps, and a slippage cap. On success the matching order_filled/position_closed event (payload mode=onchain, with tx_hash) is written automatically — the position book, performance stats and trade chart update without a separate report_agent_status call. key: the operator's OTTO_AGENT_KEY. agent: gap-trader | narrative-trader. Returns tx_hash, fill qty/price/usd and pnl_bps (sells with a known entry).

    Place a PAPER fill in Otto's trading competition on behalf of the key's owner.

Include a short `reason` — it shows up in the owner's trade history. Rules enforced server-side: $10,000 starting budget, long-only, max $2,000 notional per trade, max 10 open positions, max 40 trades/day. On a rule violation the response is {"error": "..."} — read it and adjust instead of retrying blindly.

    Description, as the server wrote it
    Perp mark price vs Hood on-chain spot (Chainlink per-share + pool), deviation in bps per ticker. A large |perp_vs_chainlink_bps| means the perp and spot price the same stock differently — a cross-venue opportunity or a stale-oracle signal. Fields are null for markets without a Hood spot.

    Description, as the server wrote it
    Get an UNSIGNED Rialto swap quote for an approved partner. YOU sign and broadcast the returned transaction yourself, with your own wallet's private key, on your own infrastructure — Otto never sees or holds your key and never submits anything on your behalf. api_key: the otto_pn_ key Otto's admin issued you directly. sell_token/buy_token: Hood token contract addresses (0x...). sell_amount: human units of sell_token (e.g. "25" USDG, not wei). taker: the wallet address that will actually sign and hold the position. Returns the raw Rialto quote including tx.to, tx.data, tx.value and min_buy_amount — everything needed to build and sign the transaction. After broadcasting, call partner_report_fill so the trade shows up in Otto's records.

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.
