What an agent can do, and what it cannot
An AI agent trading on Fensory can place orders and cannot move funds out. Fensory holds a scoped key that can sign trades only. Fensory enforces four controls on the account: a kill-switch, an access expiry, a market allow-list and a per-order cap. Fensory AG is based in Switzerland. The service is not available to US persons.
Enforced on the account, not in the prompt
A limit written into a prompt is a request. Every order placed through Fensory passes the backend first, where the controls you set decide whether it is allowed to exist.
Four controls
Kill-switch
Switch agentic trading off in the app, and every trading tool starts failing immediately.
Enforced on: The account, not the conversation.
Access expiry
Set when agentic trading access expires. After that time, new trading actions are refused until access is enabled again.
Enforced on: The account, checked before a new trading action.
Market allow-list
The agent trades only the markets you have approved. Perpetual futures and spot are authorised separately, so enabling one does not enable the other.
Enforced on: The account. Markets outside the list are unreachable.
Per-order cap
A hard ceiling on the size of any single order. A $100 cap means no order is ever $101.
Enforced on: The account, checked before the order reaches a venue.
What the agent cannot do
- Withdraw, transfer or bridge funds. Fensory holds a scoped key that can sign trades only.
- Trade a market outside your allow-list.
- Place a single order above your per-order cap.
- Keep trading after access expires.
- Keep trading after you switch agentic trading off.
The cap is per order, not a limit on total losses. Orders inside your limits can still lose money, and perpetual futures can lose more than the margin committed.

Questions people ask
- Can the agent withdraw my funds?
- No. Fensory holds a scoped key that can sign trades only. It cannot withdraw, transfer or bridge funds. Deposits and withdrawals are transactions you sign yourself in the Fensory app.
- What stops it spending more than I intended?
- A hard cap on the size of any single order, which you set in the app. It is checked on the account before the order reaches a venue, so a $100 cap means no order is ever $101. The cap is per order, not a limit on total losses.
- Where are the limits enforced?
- On the account. Every order passes the backend first, and an order outside your allow-list or above your per-order cap does not reach a venue. Nothing depends on the assistant reading, remembering or respecting an instruction.
- What happens if my assistant account is compromised?
- The account controls still apply, whatever the assistant is told. Whoever controls it could place orders in markets you approved and under your cap, and those orders can lose money. It cannot withdraw, transfer or bridge funds. Switch agentic trading off in the app to stop it.
- How long does the agent keep access?
- The agent trading key lasts 180 days, then you re-approve it in the app.
- Does Fensory hold my assets?
- Fensory does not custody customer funds. Tokenized equities and treasuries can settle on-chain to a wallet you control. Hyperliquid spot balances and perpetual-futures margin remain at the venue.
