You can use Taproot Assets to mint, send and receive assets, verify and export proofs as well as generate profiles to handle your portfolio. |
Use tapcli to begin minting your first asset. We are minting a normal, fungible asset and we'll allow ourselves to increase the supply of this asset in the future by setting the --new_grouped_asset flag.
tapcli assets mint --type normal --name beefbux --supply 100 --meta_bytes 66616e746173746963206d6f6e6579 --new_grouped_asset
This will add your asset to a minting queue called a batch, which allows multiple assets to be created in a single minting transaction. This saves fees and conserves blockspace. To execute the batch and publish your mint transaction to the blockchain run:
tapcli assets mint finalize
You will be given a batch txid, which will have to be included in a block before you can spend your newly created assets. You can also inspect the newly created asset(s) by calling the command
tapcli assets list

The output of this command can be explained as follows:
genesis_point: The first input of the minting transaction
name: The name of the asset as defined at its creation
meta: The metadata as defined at its creation
meta_hash: The hash of the metadata
asset_id: The asset ID is a digest of the information found under asset_genesis in the format sha256(genesis_outpoint || asset_tag || asset_meta || output_index || asset_type).
output index: The output of the minting transaction where the asset will be anchored. This is set to 0 while the transaction confirms
version: The asset protocol version with which this asset was created
asset_type: Whether an asset is “normal” or a collectible
amount: The quantity of this asset held by you
lock_time: An asset can be locked in time, similar to a bitcoin script
relative_lock_time: Relative locktime, analogous to bitcoin script
script version: The script protocol version with which the script was created
script_key: The script key associated with the asset
script_key_is_local: Whether you hold the key associated with this script.
asset_group:
raw_group_key: If the asset belongs to an asset group, its key will be listed here
tweaked_group_key: The tweaked key is needed to later issue more assets of this group
asset_witness: The witness (e.g. signature) used to prove that this asset was issued by the owner of the group key
chain_anchor:
anchor_tx: The raw minting transaction
anchor_txid: The hash of the minting transaction
anchor_block_hash: The hash of the block that the minting transaction was included in. This is set to zeros as the transaction is unconfirmed
anchor_outpoint: The outpoint on the bitcoin blockchain that holds the asset
internal_key: The Taproot key that holds the outpoint containing the asset
merkle_root: The merkle root of the tree that includes the asset
tapscript_sibling: The taproot leaf to the left or right of the leaf committing to the asset. It is used to calculate the merkle root
prev_witnesses: Signatures and data related to previous transfers of this asset
is_spent: Whether this asset has been spent
lease_owner: Similar to leased UTXOs in LND, tapd allows specific UTXOs to be "held" for a certain amount of time, for example while waiting for signatures or channel opens. This prevents the UTXO from being accidentally spent by another process.
lease_expiry: When the UTXO becomes available again for spending.
is_burn: Whether the asset has been burned.
{% embed url="https://www.youtube.com/watch?v=FccI6j0mxuE" %} Tapping into Taproot Assets #5: Mint from the CLI {% endembed %}
Assets that were minted with the flag --new_grouped_asset do not have a fixed supply. A new batch of this asset can be minted later in a way that the two assets are considered of the same asset group, and therefore fungible.
Note: At the moment it is not possible to spend two assets with different asset IDs, even if they belong to the same asset group.
To increase the supply of such an asset, we will need its tweaked_group_key.
tapcli assets mint --type normal --name beefbux --supply 100 --grouped_asset --group_key 02c6ca1985ae9ef257af33bb5e3389f28e798711abcb5326d8f760fdeb90c387b5
We again have to publish the new mint transaction with:
tapcli assets mint finalize
You can also specify a custom fee rate (in sat/kw) using the flag --fee_rate
Now we can check our groups with:
tapcli assets groups

To inspect your balances, run tapcli assets balance. To show the cumulative balance across asset groups, run tapcli assets balance --by_group
Taproot Assets uses universes to communicate information about which assets exist and where in the blockchain they are anchored. A universe can be thought of as a virtual mempool, an explorer or a repository.
Your node will sync with the universe whenever you create a new taproot asset address with an unknown asset ID, or when specifically instructed to. This requires an asset ID or a group key.
tapcli universe sync --universe_host <universe_ip:port> --asset_id <asset id>
Upon successful sync, information about existing assets should be retrieved, alongside their issuance proofs.
As soon as your minted assets have one confirmation on the blockchain, you are able to send them. To send assets, you will need the recipient’s Taproot Assets address. This Taproot Assets address is specific to an asset and amount, so to generate an address, the recipient needs to know an asset’s asset_id, as well as be synced to the issuer’s universe. Taproot Assets address reuse should be avoided.
When generating a Taproot Assets address, the receiver will create their expected Merkle trees, and tweak a Taproot key with it. The resulting key is converted to a Taproot address, where the receiver waits for an incoming transaction.
To generate a Taproot Assets address requesting 21 beefbux, use the following command from the tapd instance of the receiver:
tapcli addrs new --asset_id 6ab81f9b6b72138bc77189ea4afeabcfdb8722d1d5485ddbefc7a344bd9884e6 --amt 21

To send the asset, run the command below from a the tapd instance of the sender. This will generate the appropriate Merkle trees for the recipient and their change outputs, sign the Taproot Assets transaction with their internal Taproot Assets key and publish the Bitcoin transaction. Not that you cannot send unconfirmed assets.

You will notice the transaction id (00f9417fcd1d15006f2717efe0a4d7f296c38d3d84db27d650c25eca8ecb0966) has two inputs. One input is the newly minted asset (easily identifiable by its 1000 sat amount), while the other is from LND’s internal wallet. This second input is used to pay the onchain fees.
There are three outputs. Two outputs of 1000 satoshis each and the change output of LND’s internal wallet. The two 1000 satoshi inputs anchor the proofs of the sender and receiver. Even when the sender spends all of their assets, such an output is still created to carry proof of the transfer.
Once the transaction is confirmed on the Bitcoin Blockchain the sender will attempt to make the proofs available to the recipient via an end-to-end encrypted mailbox, similar to Lightning Node Connect (LNC).
By default, this mailbox is set to your default universe, but you can run your own mailbox through aperture and configure tapd to use it by specifying the --hashmailcourier.addr= flag at startup.
Once the transaction is confirmed on the Bitcoin Blockchain the sender will attempt to make the proofs available to the recipient via a LNC-style end-to-end encrypted mailbox.
