In addition to fungible, "normal" assets, Taproot Assets supports the creation and transfer of collectible, non-fungible assets. A digital collectible can take on any form. The collectible itself may be referenced in the form of a hash or text, or may be directly embedded in the meta data itself. When minting a collectible, you have the option to pass any kind of data via `--meta_bytes`, such as text, images encoded data of any form or even a binary blob. Alternatively, any file can be passed to tapd with the `--meta_file_path` flag. Meta data is limited to 1MB per asset. Example: `tapcli assets mint --type collectible --name theone --meta_bytes "One of a kind" --supply 1` `tapcli assets mint finalize` ## Collections Multiple collectibles can be grouped together into a collection. Each asset has its own asset ID, while the collection itself can be identified by its group key. To create such a collection, the `--new_group_emission` flag has to be set, and each subsequent collectible has to set the `--grouped_asset` flag as well as reference the first collectible by its name. Multiple collectibles can be minted in a batch. `tapcli assets mint --type collectible --name member001 --meta_bytes 546170726f6f742041737365747320436c7562204d656d62657220303031 --supply 1 --new_group_emission` `tapcli assets mint --type collectible --name member002 --meta_bytes 546170726f6f742041737365747320436c7562204d656d62657220303032 --grouped_asset --supply 1 --group_anchor member001` `tapcli assets mint --type collectible --name member003 --meta_bytes 546170726f6f742041737365747320436c7562204d656d62657220303033 --grouped_asset --supply 1 --group_anchor member001` `tapcli assets mint finalize` At this point there is no option to "close" a batch or limit future emissions of that group. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.lightning.engineering/lightning-network-tools/taproot-assets/collectibles.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
