Two principles make that concrete: you sign in with a wallet, and the platform is non-custodial end to end. ### Signing in with a wallet There is no password to leak. You sign in by signing a message with your wallet, which proves you control it without handing over anything that can move funds. A session lasts a set period and can be revoked everywhere at once from your account, so you are always in control of where you are signed in. ### Non-custodial by construction * **NFA never holds a key that can move your funds.** Trades are signed in your browser and settle to your own wallet on Polymarket. * **Your positions are on-chain and yours.** NFA reads them from public data to show your portfolio; it cannot touch them. * **Funding and redemption go to your wallet**, never to NFA. ### Programmatic access If you build on NFA, you create an API key from your account. The key is shown once, at creation, and stored only as a secure hash afterward, so it cannot be recovered or leaked from the platform later. Keys are scoped to your account and can be revoked at any time. See The MCP server for how agents use them. {% hint style="success" %} The short version: NFA gives you analysis and a place to act on it. It never becomes a custodian of your funds, and it never asks you to trust it with more than a signature. {% endhint %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://nfa.gitbook.io/nfa-docs/platform-and-reliability/accounts-and-safety.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
