##### Monero headers and libraries setup
|

The Onion Explorer uses Monero C++ libraries and headers. Also some functionality
|
||||
in the Explorer for mempool is achieved through [patching](https://github.com/moneroexamples/compile-monero-09-on-ubuntu-16-04/blob/master/res/tx_blob_to_tx_info.patch)
|
||||
the Monero deamon.
