# eth\_sendEndOfBlockBundle ```json { "jsonrpc": "2.0", "id": 1, "method": "eth_sendEndOfBlockBundle", "params": [ { txs, // Array[String], A list of signed transactions to execute in an atomic bundle, list can be empty for bundle cancellations blockNumber, // (Optional) String, a hex-encoded block number for which this bundle is valid. Default, current block number revertingTxHashes, // (Optional) Array[String], A list of tx hashes that are allowed to revert or be discarded targetPools, // Array[String], A list of pool addresses that this bundle is targeting replacementUuid, // (Optional) String, any arbitrary string that can be used to replace or cancel this bundle replacementSeqNumber, // (Optional) Number, monotonically increasing sequence for bundles sharing the same replacementUuid. Later bundles must have a higher sequence or they are dropped. If 0 or omitted, ordering falls back to builder receive time. } ] } ``` After building a block, any end-of-block bundle that contains a target pool that has been modified will be simulated at the end-of-block state. Successfully simulated bundles are then added to the block.\ \ Note: end-of-block bundles are handled with the same atomicity and revert guarantees as normal bundles. --- # 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.titanbuilder.xyz/api/eth_sendendofblockbundle.md?ask= ``` The question should be specific, self-contained, and written in natural language.
