ord
is an index, block explorer, and command-line wallet. It is experimental
software with no warranty. See LICENSE for more details.
Ordinal theory imbues satoshis with numismatic value, allowing them to be collected and traded as curios.
Ordinal numbers are serial numbers for satoshis, assigned in the order in which they are mined, and preserved across transactions.
See the docs for documentation and guides.
See the BIP for a technical description of the assignment and transfer algorithm.
See the project board for currently prioritized issues.
See milestones to get a sense of where the project is and where it's going.

Ordinals is open-source and community funded. The current lead maintainer of
ord
is raphjaph. Raph's work on ord
is
entirely funded by donations. If you can, please consider donating!
The donation address is bc1q8kt9pyd6r27k2840l8g5d7zshz3cg9v6rfda0m248lva3ve5072q3sxelt.
This address is 2 of 4 multisig wallet with keys held by raphjaph, erin, rodarmor, and ordinally.
Bitcoin received will go towards funding maintenance and development of ord
,
as well as hosting costs for ordinals.com.

ord
relies on Bitcoin Core for private key management and transaction signing.
This has a number of implications that you must understand in order to use
ord
wallet commands safely:
-
Bitcoin Core is not aware of inscriptions and does not perform sat control. Using
bitcoin-cli
commands and RPC calls withord
wallets may lead to loss of inscriptions. -
ord wallet
commands automatically load theord
wallet given by the--wallet
option, which defaults to 'ord'. Keep in mind that after running anord wallet
command, anord
wallet may be loaded. -
Because
ord
has access to your Bitcoin Core wallets,ord
should not be used with wallets that contain a material amount of funds. Keep ordinal and cardinal wallets segregated.
Alpha ord
wallets are not compatible with wallets created by previous
versions of ord
. To migrate, use ord wallet send
from the old wallet to
send sats and inscriptions to addresses generated by the new wallet with ord wallet receive
.
ord
is written in Rust and can be built from
source. Pre-built binaries are available on the
releases page.
You can install the latest pre-built binary from the command line with:
curl --proto '=https' --tlsv1.2 -fsLS https://ordinals.com/install.sh | bash -s
Once ord
is installed, you should be able to run ord --version
on the
command line.
On Debian and Ubuntu, ord
requires libssl-dev
when building from source:
sudo apt-get install libssl-dev
You'll also need Rust:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
To build ord
from source:
git clone https://github.com/ordinals/ord.git
cd ord
cargo build --release
Once built, the ord
binary can be found at ./target/release/ord
.
ord
requires rustc
version 1.67.0 or later. Run rustc --version
to ensure you have this version. Run rustup update
to get the latest stable release.
If you wish to contribute there are a couple things that are helpful to know. We
put a lot of emphasis on proper testing in the code base, with three broad
categories of tests: unit, integration and fuzz. Unit tests can usually be found at
the bottom of a file in a mod block called tests
. If you add or modify a
function please also add a corresponding test. Integration tests try to test
end-to-end functionality by executing a subcommand of the binary. Those can be
found in the tests directory. We don't have a lot of fuzzing but the
basic structure of how we do it can be found in the fuzz directory.
We strongly recommend installing just to make running the tests easier. To run our CI test suite you would do:
just ci
This corresponds to the commands:
cargo fmt -- --check
cargo test --all
cargo test --all -- --ignored
Have a look at the justfile to see some more helpful recipes (commands). Here are a couple more good ones:
just fmt
just fuzz
just doc
just watch ltest --all
If the tests are failing or hanging, you might need to increase the maximum
number of open files by running ulimit -n 1024
in your shell before you run
the tests, or in your shell configuration.
We also try to follow a TDD (Test-Driven-Development) approach, which means we use tests as a way to get visibility into the code. Tests have to run fast for that reason so that the feedback loop between making a change, running the test and seeing the result is small. To facilitate that we created a mocked Bitcoin Core instance in test-bitcoincore-rpc.
ord
requires a synced bitcoind
node with -txindex
to build the index of
satoshi locations. ord
communicates with bitcoind
via RPC.
If bitcoind
is run locally by the same user, without additional
configuration, ord
should find it automatically by reading the .cookie
file
from bitcoind
's datadir, and connecting using the default RPC port.
If bitcoind
is not on mainnet, is not run by the same user, has a non-default
datadir, or a non-default port, you'll need to pass additional flags to ord
.
See ord --help
for details.
ord
makes RPC calls to bitcoind
, which usually requires a username and
password.
By default, ord
looks a username and password in the cookie file created by
bitcoind
.
The cookie file path can be configured using --cookie-file
:
ord --cookie-file /path/to/cookie/file server
Alternatively, ord
can be supplied with a username and password on the
command line:
ord --bitcoin-rpc-user foo --bitcoin-rpc-pass bar server
Using environment variables:
export ORD_BITCOIN_RPC_USER=foo
export ORD_BITCOIN_RPC_PASS=bar
ord server
Or in the config file:
bitcoin_rpc_user: foo
bitcoin_rpc_pass: bar
ord
uses env_logger. Set the
RUST_LOG
environment variable in order to turn on logging. For example, run
the server and show info
-level log messages and above:
$ RUST_LOG=info cargo run server
