50    ///
51    /// One powerful use case is pairing this command with the `cast block` command, for example:

53    /// `cast block latest --full --json | reth-bench send-payload --rpc-url localhost:5000

58    ///
59    /// This command fetches transactions from real blocks and packs them into a single
60    /// block using the `testing_buildBlockV1` RPC endpoint.
61    ///
62    /// Example:
63    ///
64    /// `reth-bench generate-big-block --rpc-url http://localhost:8545 --engine-rpc-url
65    /// http://localhost:8551 --jwt-secret ~/.local/share/reth/mainnet/jwt.hex --target-gas

72    /// them in sequence using `newPayload` followed by `forkchoiceUpdated`.
73    ///
74    /// Example:
75    ///
76    /// `reth-bench replay-payloads --payload-dir ./payloads --engine-rpc-url
77    /// http://localhost:8551 --jwt-secret ~/.local/share/reth/mainnet/jwt.hex`

83    /// Engine API rejection behavior. Block hash is recalculated after modifications
84    /// unless `--invalid-block-hash` or `--skip-hash-recalc` is used.
85    ///
86    /// Example:
87    ///
88    /// `cast block latest --full --json | reth-bench send-invalid-payload --rpc-url localhost:5000
