Returns the [`BatchTransaction`] as a [`Bytes`].

Build a block using the provided transactions and push it through the engine.

Return the latest recovered block as seen by the local blockchain provider.

Get the block number.

Processes a send error, updating internal state accordingly. - [`TxManagerError::NonceTooLow`] increments the nonce-too-low counter. - [`TxManagerErr

Appends an entry to the buffer. If the buffer is at capacity, the oldest entry is evicted first.

Read the raw data of the first channel, if it's timed-out or closed. Returns an error if there is nothing new to read.

Returns a mutable reference to the inner RNG.

Appends a transaction, preserving sequencer order.

Seek to the first non-deleted latest version at or after `start_key`. Logic: - Try exact key first (above). If alive, return it. - Otherwise hop to ne
