- It is HIGHLY recommended that you join the #monero-dev IRC channel if you are developing software that uses Monero. Due to the nature of this open source software project, joining this channel and idling is the best way to stay updated on best practices and new developments in the Monero ecosystem. All you need to do is join the IRC channel and idle to stay updated with the latest in Monero development. If you do not, you risk wasting resources on developing integrations that are not compatible with the Monero network. The Monero core team and community continuously make efforts to communicate updates, developments, and documentation via other platforms – but for the best information, you need to talk to other Monero developers, and they are on IRC. #monero-dev is about Monero development, not getting help about using Monero, or help about development of other software, including yours, unless it also pertains to Monero code itself. For these cases, checkout #monero.
- Our Vulnerability Response Process encourages responsible disclosure
- We are also available via HackerOne
The Monero Research Lab is an open forum where the community coordinates research into Monero cryptography, protocols, fungibility, analysis, and more. We welcome collaboration and contributions from outside researchers! Because not all Lab work and publications are distributed as traditional preprints or articles, they may be easy to miss if you are conducting literature reviews for your own Monero research. You are encouraged to get in touch with the Monero research community if you have questions, wish to collaborate, or would like guidance to help avoid unnecessarily duplicating earlier or known work.
The Monero research community is available on IRC in #monero-research-lab on Libera, which is also accessible via Matrix.
- You can subscribe to an announcement listserv to get critical announcements from the Monero core team. The announcement list can be very helpful for knowing when software updates are needed.
The CLI wallet is available in different languages. If you want to help translate it, see our self-hosted localization platform, Weblate, on translate.getmonero.org. Every translation must be uploaded on the platform, pull requests directly editing the code in this repository will be closed. If you need help with Weblate, you can find a guide with screenshots here. Â
If you need help/support/info about translations, contact the localization workgroup. You can find the complete list of contacts on the repository of the workgroup: monero-translations.

Monero is a private, secure, untraceable, decentralised digital currency. You are your bank, you control your funds, and nobody can trace your transfers unless you allow them to do so.
Privacy: Monero uses a cryptographically sound system to allow you to send and receive funds without your transactions being easily revealed on the blockchain (the ledger of transactions that everyone has). This ensures that your purchases, receipts, and all transfers remain private by default.
Security: Using the power of a distributed peer-to-peer consensus network, every transaction on the network is cryptographically secured. Individual wallets have a 25-word mnemonic seed that is only displayed once and can be written down to backup the wallet. Wallet files should be encrypted with a strong passphrase to ensure they are useless if ever stolen.
Untraceability: By taking advantage of ring signatures, a special property of a certain type of cryptography, Monero is able to ensure that transactions are not only untraceable but have an optional measure of ambiguity that ensures that transactions cannot easily be tied back to an individual user or computer.
Decentralization: The utility of Monero depends on its decentralised peer-to-peer consensus network - anyone should be able to run the monero software, validate the integrity of the blockchain, and participate in all aspects of the monero network using consumer-grade commodity hardware. Decentralization of the monero network is maintained by software development that minimizes the costs of running the monero software and inhibits the proliferation of specialized, non-commodity hardware.
This is the core implementation of Monero. It is open source and completely free to use without restrictions, except for those specified in the license agreement below. There are no restrictions on anyone creating an alternative implementation of Monero that uses the protocol and network in a compatible manner.
As with many development projects, the repository on GitHub is considered to be the "staging" area for the latest changes. Before changes are merged into that branch on the main repository, they are tested by individual developers in their own branches, submitted as a pull request, and then subsequently tested by contributors who focus on testing and code reviews. That having been said, the repository should be carefully considered before using it in a production environment, unless there is a patch in the repository for a particular show-stopping issue you are experiencing. It is generally a better idea to use a tagged release for stability.
Anyone is welcome to contribute to Monero's codebase! If you have a fix or code change, feel free to submit it as a pull request directly to the "master" branch. In cases where the change is relatively small or does not affect other parts of the codebase, it may be merged in immediately by any one of the collaborators. On the other hand, if the change is particularly large or complex, it is expected that it will be discussed at length either well in advance of the pull request being submitted, or even directly on the pull request.
Monero is a 100% community-sponsored endeavor. If you want to join our efforts, the easiest thing you can do is support the project financially. Both Monero and Bitcoin donations can be made to donate.getmonero.org if using a client that supports the OpenAlias standard. Alternatively, you can send XMR to the Monero donation address via the donate command (type help in the command-line wallet for details).

Monero uses a fixed-schedule software upgrade (hard fork) mechanism to implement new features. This means that users of Monero (end users and service providers) should run current versions and upgrade their software on a regular schedule. Software upgrades occur during the months of April and October. The required software for these upgrades will be available prior to the scheduled date. Please check the repository prior to this date for the proper Monero software version. Below is the historical schedule and the projected schedule for the next upgrade. Dates are provided in the format YYYY-MM-DD.

Approximately three months prior to a scheduled software upgrade, a branch from master will be created with the new release version tag. Pull requests that address bugs should then be made to both master and the new release branch. Pull requests that require extensive review and testing (generally, optimizations and new features) should not be made to the release branch.
The following table summarizes the tools and libraries required to build. A
few of the libraries are also included in this repository (marked as
"Vendored"). By default, the build uses the library installed on the system
and ignores the vendored sources. However, if no library is found installed on
the system, then the vendored source will be built and used. The vendored
sources are also used for statically-linked builds because distribution
packages often include only shared library binaries (.so) but not static
library archives (.a).

[1] On Debian/Ubuntu libgtest-dev only includes sources and headers. You must
build the library binary manually. This can be done with the following command sudo apt-get install libgtest-dev && cd /usr/src/gtest && sudo cmake . && sudo make
then:
- on Debian:
sudo mv libg* /usr/lib/ - on Ubuntu:
sudo mv lib/libg* /usr/lib/
[2] libnorm-dev is needed if your zmq library was built with libnorm, and not needed otherwise

Clone recursively to pull-in needed submodule(s):
git clone --recursive https://github.com/monero-project/monero
If you already have a repo cloned, initialize and update:
cd monero && git submodule init && git submodule update
Note: If there are submodule differences between branches, you may need
to use git submodule sync && git submodule update after changing branches
to build successfully.
Monero uses the CMake build system and a top-level Makefile that invokes cmake commands as needed.
-
Install the dependencies
-
Change to the root of the source code directory, change to the most recent release branch, and build:
cd monero git checkout release-v0.18 makeOptional: If your machine has several cores and enough memory, enable parallel build by running
make -j<number of threads>instead ofmake. For this to be worthwhile, the machine should have one core and about 2GB of RAM available per thread.Note: The instructions above will compile the most stable release of the Monero software. If you would like to use and test the most recent software, use
git checkout master. The master branch may contain updates that are both unstable and incompatible with release software, though testing is always encouraged. -
The resulting executables can be found in
build/release/bin -
Add
PATH="$PATH:$HOME/monero/build/release/bin"to.profile -
Run Monero with
monerod --detach -
Optional: build and run the test suite to verify the binaries:
make release-test
NOTE:
core_teststest may take a few hours to complete. -
Optional: to build binaries suitable for debugging:
make debug
-
Optional: to build statically-linked binaries:
make release-static
Dependencies need to be built with -fPIC. Static libraries usually aren't, so you may have to build them yourself with -fPIC. Refer to their documentation for how to build them.
-
Optional: build documentation in
doc/html(omitHAVE_DOT=YESifgraphvizis not installed):HAVE_DOT=YES doxygen Doxyfile
-
Optional: use ccache not to rebuild translation units, that haven't really changed. Monero's CMakeLists.txt file automatically handles it
sudo apt install ccache
Tested on a Raspberry Pi Zero with a clean install of minimal Raspbian Stretch (2017-09-07 or later) from https://www.raspberrypi.org/downloads/raspbian/. If you are using Raspian Jessie, please see note in the following section.
-
apt-get update && apt-get upgradeto install all of the latest software -
Install the dependencies for Monero from the 'Debian' column in the table above.
-
Increase the system swap size:
sudo /etc/init.d/dphys-swapfile stop sudo nano /etc/dphys-swapfile CONF_SWAPSIZE=2048 sudo /etc/init.d/dphys-swapfile start
-
If using an external hard disk without an external power supply, ensure it gets enough power to avoid hardware issues when syncing, by adding the line "max_usb_current=1" to /boot/config.txt
-
Clone Monero and checkout the most recent release version:
git clone https://github.com/monero-project/monero.git cd monero git checkout v0.18.4.0 -
Build:
USE_SINGLE_BUILDDIR=1 make release
-
Wait 4-6 hours
-
The resulting executables can be found in
build/release/bin -
Add
export PATH="$PATH:$HOME/monero/build/release/bin"to$HOME/.profile -
Run
source $HOME/.profile -
Run Monero with
monerod --detach -
You may wish to reduce the size of the swap file after the build has finished, and delete the boost directory from your home directory
If you are using the older Raspbian Jessie image, compiling Monero is a bit more complicated. The version of Boost available in the Debian Jessie repositories is too old to use with Monero, and thus you must compile a newer version yourself. The following explains the extra steps and has been tested on a Raspberry Pi 2 with a clean install of minimal Raspbian Jessie.
-
As before,
apt-get update && apt-get upgradeto install all of the latest software, and increase the system swap sizesudo /etc/init.d/dphys-swapfile stop sudo nano /etc/dphys-swapfile CONF_SWAPSIZE=2048 sudo /etc/init.d/dphys-swapfile start
-
Then, install the dependencies for Monero except for
libunwindandlibboost-all-dev -
Install the latest version of boost (this may first require invoking
apt-get remove --purge libboost*-devto remove a previous version if you're not using a clean install):cd wget https://sourceforge.net/projects/boost/files/boost/1.72.0/boost_1_72_0.tar.bz2 tar xvfo boost_1_72_0.tar.bz2 cd boost_1_72_0 ./bootstrap.sh sudo ./b2
-
Wait ~8 hours
sudo ./bjam cxxflags=-fPIC cflags=-fPIC -a install
-
Wait ~4 hours
-
From here, follow the general Raspberry Pi instructions from the "Clone Monero and checkout most recent release version" step.
Binaries for Windows are built on Windows using the MinGW toolchain within MSYS2 environment. The MSYS2 environment emulates a POSIX system. The toolchain runs within the environment and cross-compiles binaries that can run outside of the environment as a regular Windows application.
Preparing the build environment
-
Download and install the MSYS2 installer, either the 64-bit or the 32-bit package, depending on your system.
-
Open the MSYS shell via the
MSYS2 Shellshortcut -
Update packages using pacman:
pacman -Syu
-
Exit the MSYS shell using Alt+F4
-
Edit the properties for the
MSYS2 Shellshortcut changing "msys2_shell.bat" to "msys2_shell.cmd -mingw64" for 64-bit builds or "msys2_shell.cmd -mingw32" for 32-bit builds -
Restart MSYS shell via modified shortcut 9E88 and update packages again using pacman:
pacman -Syu
-
Install dependencies:
To build for 64-bit Windows:
pacman -S mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-openssl mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium mingw-w64-x86_64-hidapi mingw-w64-x86_64-unbound
To build for 32-bit Windows:
pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-zeromq mingw-w64-i686-libsodium mingw-w64-i686-hidapi mingw-w64-i686-unbound
-
Open the MingW shell via
MinGW-w64-Win64 Shellshortcut on 64-bit Windows orMinGW-w64-Win64 Shellshortcut on 32-bit Windows. Note that if you are running 64-bit Windows, you will have both 64-bit and 32-bit MinGW shells.
Cloning
-
To git clone, run:
git clone --recursive https://github.com/monero-project/monero.git
Building
-
Change to the cloned directory, run:
cd monero -
If you would like a specific version/tag, do a git checkout for that version. eg. 'v0.18.4.0'. If you don't care about the version and just want binaries from master, skip this step:
git checkout v0.18.4.0
-
If you are on a 64-bit system, run:
make release-static-win64
-
If you are on a 32-bit system, run:
make release-static-win32
-
The resulting executables can be found in
build/release/bin -
Optional: to build Windows binaries suitable for debugging on a 64-bit system, run:
make debug-static-win64
-
Optional: to build Windows binaries suitable for debugging on a 32-bit system, run:
make debug-static-win32
-
The resulting executables can be found in
build/debug/bin
The project can be built from scratch by following instructions for Linux above(but use gmake instead of make).
If you are running Monero in a jail, you need to add sysvsem="new" to your jail configuration, otherwise lmdb will throw the error message: Failed to open lmdb environment: Function not implemented.
Monero is also available as a port or package as monero-cli.
You will need to add a few packages to your system. pkg_add cmake gmake zeromq libiconv boost.
The doxygen and graphviz packages are optional and require the xbase set.
Running the test suite also requires py-requests package.
Build monero: env DEVELOPER_LOCAL_TOOLS=1 BOOST_ROOT=/usr/local gmake release-static
Note: you may encounter the following error when compiling the latest version of Monero as a normal user:
LLVM ERROR: out of memory
c++: error: unable to execute command: Abort trap (core dumped)
Then you need to increase the data ulimit size to 2GB and try again: ulimit -d 2000000
Check that the dependencies are present: pkg_info -c libexecinfo boost-headers boost-libs protobuf readline libusb1 zeromq git-base pkgconf gmake cmake | more, and install any that are reported missing, using pkg_add or from your pkgsrc tree. Readline is optional but worth having.
Third-party dependencies are usually under /usr/pkg/, but if you have a custom setup, adjust the "/usr/pkg" (below) accordingly.
Clone the monero repository recursively and checkout the most recent release as described above. Then build monero: gmake BOOST_ROOT=/usr/pkg LDFLAGS="-Wl,-R/usr/pkg/lib" release. The resulting executables can be found in build/NetBSD/[Release version]/Release/bin/.
The default Solaris linker can't be used, you have to install GNU ld, then run cmake manually with the path to your copy of GNU ld:
mkdir -p build/release
cd build/release
cmake -DCMAKE_LINKER=/path/to/ld -D CMAKE_BUILD_TYPE=Release ../..
cd ../..Then you can run make as usual.
By default, in either dynamically or statically linked builds, binaries target the specific host processor on which the build happens and are not portable to other processors. Portable binaries can be built using the following targets:
make release-static-linux-x86_64builds binaries on Linux on x86_64 portable across POSIX systems on x86_64 processorsmake release-static-linux-i686builds binaries on Linux on x86_64 or i686 portable across POSIX systems on i686 processorsmake release-static-linux-armv8builds binaries on Linux portable across POSIX systems on armv8 processorsmake release-static-linux-armv7builds binaries on Linux portable across POSIX systems on armv7 processorsmake release-static-linux-armv6builds binaries on Linux portable across POSIX systems on armv6 processorsmake release-static-win64builds binaries on 64-bit Windows portable across 64-bit Windows systemsmake release-static-win32builds binaries on 64-bit or 32-bit Windows portable across 32-bit Windows systems
You can also cross-compile static binaries on Linux for Windows and macOS with the depends system.

The required packages are the names for each toolchain on apt. Depending on your distro, they may have different names. The depends system has been tested on Ubuntu 18.04 and 20.04.
Using depends might also be easier to compile Monero on Windows than using MSYS. Activate Windows Subsystem for Linux (WSL) with a distro (for example Ubuntu), install the apt build-essentials and follow the depends steps as depicted above.
The produced binaries still link libc dynamically. If the binary is compiled on a current distribution, it might not run on an older distribution with an older installation of libc. Passing -DBACKCOMPAT=ON to cmake will make sure that the binary will run on systems having at least libc version 2.17.
DISCLAIMER: These packages are not part of this repository or maintained by this project's contributors, and as such, do not go through the same review process to ensure their trustworthiness and security.

The build places the binary in bin/ sub-directory within the build directory
from which cmake was invoked (repository root by default). To run in the
foreground:
./bin/monerodTo list all available options, run ./bin/monerod --help. Options can be
specified either on the command line or in a configuration file passed by the
--config-file argument. To specify an option in the configuration file, add
a line with the syntax argumentname=value, where argumentname is the name
of the argument without the leading dashes, for example, log-level=1.
To run in background:
./bin/monerod --log-file monerod.log --detachTo run as a systemd service, copy
monerod.service to /etc/systemd/system/ and
monerod.conf to /etc/. The example
service assumes that the user monero exists
and its home is the data directory specified in the example
config.
If you're on Mac, you may need to add the --max-concurrency 1 option to
monero-wallet-cli, and possibly monerod, if you get crashes refreshing.
See README.i18n.md.
There is a new, still experimental, integration with Tor. The feature allows connecting over IPv4 and Tor simultaneously - IPv4 is used for relaying blocks and relaying transactions received by peers whereas Tor is used solely for relaying transactions received over local RPC. This provides privacy and better protection against surrounding node (sybil) attacks.
While Monero isn't made to integrate with Tor, it can be used wrapped with torsocks, by setting the following configuration parameters and environment variables:
--p2p-bind-ip 127.0.0.1on the command line orp2p-bind-ip=127.0.0.1in monerod.conf to disable listening for connections on external interfaces.--no-igdon the command line orno-igd=1in monerod.conf to disable IGD (UPnP port forwarding negotiation), which is pointless with Tor.DNS_PUBLIC=tcporDNS_PUBLIC=tcp://x.x.x.xwhere x.x.x.x is the IP of the desired DNS server, for DNS requests to go over TCP, so that they are routed through Tor. When IP is not specified, monerod uses the default list of servers defined in src/common/dns_utils.cpp.TORSOCKS_ALLOW_INBOUND=1to tell torsocks to allow monerod to bind to interfaces to accept connections from the wallet. On some Linux systems, torsocks allows binding to localhost by default, so setting this variable is only necessary to allow binding to local LAN/VPN interfaces to allow wallets to connect from remote hosts. On other systems, it may be needed for local wallets as well.- Do NOT pass
--detachwhen running through torsocks with systemd, (see utils/systemd/monerod.service for details). - If you use the wallet with a Tor daemon via the loopback IP (eg, 127.0.0.1:9050),
then use
--untrusted-daemonunless it is your own hidden service.
Example command line to start monerod through Tor:
DNS_PUBLIC=tcp torsocks monerod --p2p-bind-ip 127.0.0.1 --no-igdA helper script is in contrib/tor/monero-over-tor.sh. It assumes Tor is installed already, and runs Tor and Monero with the right configuration.
TAILS ships with a very restrictive set of firewall rules. Therefore, you need to add a rule to allow this connection too, in addition to telling torsocks to allow inbound connections. Full example:
sudo iptables -I OUTPUT 2 -p tcp -d 127.0.0.1 -m tcp --dport 18081 -j ACCEPT
DNS_PUBLIC=tcp torsocks ./monerod --p2p-bind-ip 127.0.0.1 --no-igd --rpc-bind-ip 127.0.0.1 \
--data-dir /home/amnesia/Persistent/your/directory/to/the/blockchainAs of April 2022, the full Monero blockchain file is about 130 GB. One can store a pruned blockchain, which is about 45 GB.
A pruned blockchain can only serve part of the historical chain data to other peers, but is otherwise identical in
functionality to the full blockchain.
To use a pruned blockchain, it is best to start the initial sync with --prune-blockchain. However, it is also possible
to prune an existing blockchain using the monero-blockchain-prune tool or using the --prune-blockchain monerod option
with an existing chain. If an existing chain exists, pruning will temporarily require disk space to store both the full
and pruned blockchains.
For more detailed information see the 'Pruning' entry in the Moneropedia
This section contains general instructions for debugging failed installs or problems encountered with Monero. First, ensure you are running the latest version built from the GitHub repo.
We generally use the tool gdb (GNU debugger) to provide stack trace functionality, and ulimit to provide core dumps in builds which crash or segfault.
- To use
gdbin order to obtain a stack trace for a build that has stalled:
Run the build.
Once it stalls, enter the following command:
gdb /path/to/monerod `pidof monerod`Type thread apply all bt within gdb in order to obtain the stack trace
- If however the core dumps or segfaults:
Enter ulimit -c unlimited on the command line to enable unlimited filesizes for core dumps
Enter echo core | sudo tee /proc/sys/kernel/core_pattern to stop cores from being hijacked by other tools
Run the build.
When it terminates with an output along the lines of "Segmentation fault (core dumped)", there should be a core dump file in the same directory as monerod. It may be named just core, or core.xxxx with numbers appended.
You can now analyse this core dump with gdb as follows:
gdb /path/to/monerod /path/to/dumpfile`Print the stack trace with bt
- If a program crashed and cores are managed by systemd, the following can also get a stack trace for that crash:
coredumpctl -1 gdbType gdb /path/to/monerod
Pass command-line options with --args followed by the relevant arguments
Type run to run monerod
There are two tools available:
Configure Monero with the -D SANITIZE=ON cmake flag, eg:
cd build/debug && cmake -D SANITIZE=ON -D CMAKE_BUILD_TYPE=Debug ../..You can then run the monero tools normally. Performance will typically halve.
Install valgrind and run as valgrind /path/to/monerod. It will be very slow.
Instructions for debugging suspected blockchain corruption as per @HYC
There is an mdb_stat command in the LMDB source that can print statistics about the database but it's not routinely built. This can be built with the following command:
cd ~/monero/external/db_drivers/liblmdb && makeThe output of mdb_stat -ea <path to blockchain dir> will indicate inconsistencies in the blocks, block_heights and block_info table.
The output of mdb_dump -s blocks <path to blockchain dir> and mdb_dump -s block_info <path to blockchain dir> is useful for indicating whether blocks and block_info contain the same keys.
These records are dumped as hex data, where the first line is the key and the second line is the data.
Because of the nature of the socket-based protocols that drive monero, certain protocol weaknesses are somewhat unavoidable at this time. While these weaknesses can theoretically be fully mitigated, the effort required (the means) may not justify the ends. As such, please consider taking the following precautions if you are a monero node operator:
- Run
monerodon a "secured" machine. If operational security is not your forte, at a very minimum, have a dedicated a computer runningmonerodand do not browse the web, use email clients, or use any other potentially harmful apps on yourmonerodmachine. Do not click links or load URL/MUA content on the same machine. Doing so may potentially exploit weaknesses in commands which accept "localhost" and "127.0.0.1". - If you plan on hosting a public "remote" node, start
monerodwith--restricted-rpc. This is a must.
Certain blockchain "features" can be considered "bugs" if misused correctly. Consequently, please consider the following:
- When receiving monero, be aware that it may be locked for an arbitrary time if the sender elected to, preventing you from spending that monero until the lock time expires. You may want to hold off acting upon such a transaction until the unlock time lapses. To get a sense of that time, you can consider the remaining blocktime until unlock as seen in the
show_transferscommand.
