# Wallets For use-cases that involve blockchain interaction, either within a single chain or on multi-chain workflows, hot wallets will need to be generated to receive/send transactions. Each wallet is created with it's own private key, which is stored securely within our secrets vault. While wallets can be persistent and used repeatedly, we recommend that you adhere to a single-use principal and ensure that no funds are left in the wallet by the end of your workflow runs. For multi-tenant systems - such as a CEX that needs to receive user deposits - creating a new deposit address for every transaction may not be desirable, however you can still maintain the 'zero funds' method by automatically sweeping remainders to a central custodial address at the end of every workflow. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.wundaflow.com/core-concepts/wallets.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
