Entry points
Three ways to place an order. The same limits on all of them.
Your wallet in the app, x402 agents calling typed MCP tools and paying per call, and Desk subscribers using the REST API with replay-safe webhooks. Each check is read off your account rather than off the instruction, which is why the surface that asked makes no difference to what is allowed. Sessions are bound to the device that opened them.
Your wallet
Your keys are generated on the device and stay there.
There is no seed phrase held on a Fexr server, which is why there is nothing on our side to leak. The trading permission places orders and cannot withdraw — moving funds out is something only your wallet does, and that is not a limitation we intend to remove. Hardware wallets sign the same way, across 29 networks.
The check
Six checks, in the code that submits the order.
You define a space — how much, which assets, how concentrated, how much leverage, for how long — and nothing inside it needs a confirmation. Every order is checked against it before submission: size against your book, concentration, leverage as distance to liquidation, how old the price behind the decision is, what funding costs, and whether we trade the asset at all. This runs on every path to the exchange. There is no route around it. The rules that stop an order opening a position never apply to closing one — a check that could trap you in a trade would not be a safety feature.
The venue
Orders land on Hyperliquid.
Spot and perpetuals on one onchain order book, with no house taking the other side of your fill. Leaderboards rank on realised performance and every strategy template carries the backtest it was ranked on. A copied strategy runs under your own cap and limits, not the author's, so you do not inherit the risk appetite it was written with.

Intelligence
Reports and signals, with Plus or Desk.
Coverage across crypto, stocks & ETFs and commodities, computed on a schedule rather than assembled by hand, with the reasoning attached. Fexr Plus brings signals, Copilot answers and 5 insight reports per week for $15 a month; Fexr Desk is $2,500 a year for organizations, with unlimited reports within fair use plus the workspace, security and controls to run them across a team. On Free, buy any report as a pay-per-call add-on over x402. A report can inform an order. It cannot widen the permission that order runs under.
