# Transaction Propagator The Transaction Propagator is an HTTP endpoint that users may leverage to propagate their transactions faster through Avalanche C-Chain. Any transactions recevied by the Transaction Propagator are immediately relayed throughout Snowsight's validator node network, resulting in much better performance than a public RPC. Similar to the Mempool Stream, users must authenticate by sending their `'signed_key'` in the same payload that contains their transaction. --- # 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.snowsight.chainsight.dev/snowsight/services/transaction-propagator.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.
