Safex Blockchain Explorer

This is the Safex blockchain explorer. This is a fork of Onion Monero Blockchain Explorer

Safex Blockchain Explorer features

The key features of the Safex Blockchain Explorer are:

  • no cookies, no web analytics trackers, no images,
  • by default no JavaScript, but can be enabled for client side decoding and proving transactions,
  • open sourced,
  • made fully in C++,
  • showing encrypted payments ID,
  • showing ring signatures,
  • showing transaction extra field,
  • showing public components of Safex addresses,
  • decoding which outputs and mixins belong to the given Safex address and viewkey,
  • can prove that you send Safex cash to someone,
  • detailed information about ring members, such as, their age, timescale and their ring sizes,
  • showing number of amount output indices,
  • support Safex testnet and stagenet networks,
  • tx checker and pusher for online pushing of transactions,
  • estimate possible spendings based on address and viewkey,
  • can provide total amount of all miner fees,
  • decoding encrypted payment id,
  • decoding outputs and proving txs sent to sub-address.

Compilation on Ubuntu 18.04

Compile latest Safex development version

Download and compile recent safexcore into your home folder:

# first install safex dependecines
sudo apt update

sudo apt install git build-essential cmake libboost-all-dev miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config libssl-dev libcurl4-openssl-dev libgtest-dev libreadline-dev libzmq3-dev libsodium-dev libpcsclite-dev

# go to home folder
cd ~

git clone --recursive

cd safeccore/

# checkout last safex version
git checkout master

Compile and run the explorer

Once the Safex is compiles, the explorer can be downloaded and compiled as follows:

cd ~

# download the source code
git clone

# enter the downloaded sourced code folder
cd safex-blockchain-explorer

# make a build folder and enter it
mkdir build && cd build

# create the makefile
cmake ..

# altearnatively can use: cmake -DSAFEX_DIR=/path/to/safexcore_folder ..
# also can build with ASAN (sanitizers), for example

# compile

To run it:


By default it will look for blockchain in its default location i.e., ~/.safex/lmdb. You can use -b option if its in different location.

For example:

./safex-explorer -b /home/user/non-defult-safex-location/lmdb/

Example output:

Example usage, defined as bash aliases.

# for mainnet explorer
alias xmrblocksmainnet='~/safex-blockchain-explorer/build/safex-explorer --port 8081 --testnet-url "" --enable-pusher --enable-emission-monitor'

# for testnet explorer
