Fees
The two cost streams you can pay, what sets each one, and where to read the live numbers.
There are two separate cost streams in the app, and they never mix. Trading fees are charged by the venue and paid from your trading collateral. AI suggestion calls are charged per call and paid from your Agent Wallet. This page explains both.
Live numbers come from the venue, not from us
We do not set venue trading fees, and they change. The app reads your current fee tier from the venue and shows it in the order ticket before you confirm. The numbers below are the venue's standard starting tier — your own rate is what the ticket displays, and it only goes down as your volume grows.
Two cost streams at a glance
| Cost stream | Who charges it | Paid from | When |
|---|---|---|---|
| Trading fees | the venue | your trading collateral | on each trade you place |
| AI suggestion calls | the paid AI provider | your Agent Wallet (USDC) | per call, only on a cache miss |
Trading fees
These are the costs of placing and holding a perpetual position. They belong to the venue, and the app surfaces them the same way across every exchange.
Words you will see:
- Maker means your order rests on the book and waits to be matched.
- Taker means your order fills against an order that is already there.
- Funding is a recurring payment exchanged between longs and shorts to keep the perpetual price near the spot price. It is not a fee the app charges.
- Builder fee is a small venue-side routing fee you approve once during Venue Onboarding.
- Gas is the network cost of an on-chain action.
Hyperliquid
The first live venue. The trading-fee row is the standard starting tier; your live, tier-adjusted rate is read from the venue and shown in the order ticket.

| Funding | varies | varies | paid hourly between longs and shorts, not charged by the app |
| Builder fee | 0.035% | 0.035% | a flat routing fee, approved once at onboarding |
mock-venue
The synthetic venue used for development and demos. It does not touch real money and charges no real fees. Any numbers it shows are simulated.
AI suggestion calls
Paid AI suggestions are settled from your Agent Wallet in USDC, using the x402 payment standard. This balance, the Agent Balance, is completely separate from your trading collateral.
Three rules keep this honest:
- You pay per call, not per session. You are charged when your chosen AI Agent actually runs, and only if it is a paid Agent.
- A repeat question is free. The app caches recent answers. Ask the same thing again inside the freshness window and you get the cached result at no cost.
- A bad request never costs you anything. Before paying, the app checks that the symbol is listed, the leverage is under the cap, and your Agent Balance covers the call. If any check fails it returns an error and calls no Agent.
| Item | Amount | Paid from | Notes |
|---|---|---|---|
| Per-call Agent price | read live from the Agent | Agent Wallet (USDC) | the price is quoted before the call runs |
| Cached answer | free | n/a | within the freshness window |
| Invalid request | free | n/a | rejected before any Agent is called |
The Agent Wallet holds USDC across Base and Polygon, and a call routes to whichever chain has the funds. You can deposit, withdraw, and revoke the spending delegation at any time. See self-custody for the exact scope of what that wallet can do.
