+.P
+Checksum protection may be used as protection against address typos.
+.P
+It uses the value of the address itself as input to an algorithm, which results in altering the case of the letters in the hexadecimal address.

+.P
+This tool deserializes a wire-format transaction and outputs its fields in human-readable form. It does not require a node to operate, and does not apply transaction state.

+The transaction wire-format is an ordered concatenation of transaction values, which in turn is serialized using the Recurive Length Prefix (RLP) format. \fBeth-decode\fP accepts the RLP-encoded transaction as a hex string.
