Your funds are deposited into Orderly Network's settlement smart contracts, and withdrawals always go back to your connected wallet. ## Your trading key When you **enable trading**, your wallet signs a message that creates a trading key in your browser. This key lets SigSig submit orders on your behalf without a wallet pop-up for every order. * The trading key can place and cancel orders. * It **cannot** withdraw your funds — withdrawals always require a signature from your wallet. * It is stored in your browser. If you clear your browser data or switch device, simply enable trading again. ## Using another device Use **Link device** in the header to move your trading session to another device, for example your phone, by scanning a QR code. ## Stay safe * SigSig will never ask for your seed phrase or private key. * Always check that you are on the official SigSig domain before connecting your wallet. * Only sign messages and transactions you understand. --- # 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://docs.sigsig.xyz/core-concepts/wallet-and-security.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.
