To make use of all Taproot Assets features, you must run litd in integrated mode, meaning all binaries, including LND and tapd are running as part of one binary.
If you do not need to make use of Lightning channels, you may install tapd as a standalone binary with a connection to LND. If LND is compiled from source, it needs to be built using tags=signrpc walletrpc chainrpc invoicesrpc
LND needs to be synced and running on the same bitcoin network as tapd. RPC connections need to be accepted and Macaroons need to be set.. For onchain operations, this LND node should have some funds in its onchain wallet, but does not need open channels to mint, send and receive Taproot Assets on chain.
Compile Taproot Assets from source by cloning the taproot-assets repository. or higher is recommended (you may check what version of go is running with go version).
git clone https://github.com/lightninglabs/taproot-assets.git
cd taproot-assets
checkout <latest version>
make install
Optionally, create a Taproot Assets configuration file under ~/.tapd/tapd.conf on Linux or BSD, ~/Library/Application Support/tapd/tapd.conf in Mac OS or $LOCALAPPDATA/Tapd/tap.conf in Windows.
Within the tapd.conf file you can permanently set your variables, such as directory, macaroon or other paths and how to connect to your LND.
As there is currently no migration path between the SQLite and Postgres backends, the backend needs to be configured when tapd is first initialized.
taproot-assets.proofcourieraddr=universerpc://universe.signet.laisee.org:8443
Using the command line:
tapcli universe federation add --universe_host universe.signet.laisee.org:8443
Run Taproot Assets with the command tapd. Specify how Taproot Assets can reach LND and what bitcoin network to run Taproot Assets with by passing it additional flags.
tapd --network=signet --debuglevel=debug --lnd.host=localhost:10009 --lnd.macaroonpath=/home/ubuntu/.lnd/data/chain/bitcoin/signet/admin.macaroon --lnd.tlspath=/home/ubuntu/.lnd/tls.cert --tapddir=~/.tapd --rpclisten=127.0.0.1:10029 --restlisten=127.0.0.1:8089
For example, to run a second instance of tapd:
tapd --tapddir=~/.tapd-2 --rpclisten=127.0.0.1:10030 --restlisten=127.0.0.1:8090
To interact with this second instance using tapcli:
tapcli --rpcserver=127.0.0.1:10030 --tapddir=~/.tapd-2
You can make use of tapcli profiles to make calls to separate tapd instances on the same machine.
Tapd is included in the Litd bundle. This allows you to run LND and Tapd in the same process and removes the need to configure the two separately.
Lightning Labs currently does not provide a Taproot Asset Universe on Signet. In addition to , users will have to . To properly close channels, both peers will have to configure the same proof courier as well. In the lit.conf:
You may run multiple tapd instances on the same machine, but you will also have to set up multiple LND instances. for how to set up multiple LND instances with a single Bitcoin backend using rpcpolling. When running multiple tapd instances on one machine, don’t forget to set an alternate Taproot Assets directory and API endpoints and specify these when calling tapcli as well.
