It is part of the Fast ecosystem, but unlike the standard Fast model which requires attaching a tip to the transaction, Broadcast Tx does not require users to pay extra for a tip within the transaction, making it more suitable as a low-barrier, fast sending entry point. Currently, Broadcast Tx offers methods `SendTx` which are used to send single transactions. It's important to note that while Broadcast Tx belongs to the Fast ecosystem, it is not equivalent to a private transmission channel with full transaction protection capabilities. Transactions sent via Broadcast Tx still enter the public propagation path and therefore *DO NOT* have MEV protection capabilities. ### In what scenarios should you choose Broadcast Tx * No tips needed, lower barrier to entry\ Unlike the standard Fast model, Broadcast Tx does not require adding tips to transactions, making it more suitable for users who want to quickly integrate but do not want to modify the transaction incentive structure. * Suitable for scenarios where speed is a requirement but MEV protection is not currently emphasized\ If your priority is to send transactions out as quickly as possible, rather than hiding transactions or mitigating risks like sandwiches and frontrunnings through private paths, then Broadcast Tx would be a more straightforward option. --- # 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.blockrazor.io/transaction-submission/transaction-sending/ethereum.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.
