Open-source specification for interacting with digital assets on Solana
Open-source specification for interacting with digital assets on Solana.
The state data of uncompressed NFTs is all stored in on-chain accounts. This is expensive at scale. Compressed NFTs save space by encoding the state data into an on-chain Merkle tree. The detailed account data is not stored on-chain, but in data stores managed by RPC providers. The Metaplex D
igital A
sset S
tandard (DAS) API represents a unified interface for interacting with digital assets on Solana, supporting both standard (Token Metadata) and compressed (Bubblegum) assets.
The API defines a set of methods that RPCs implement in order to provide asset data. In the majority of cases, the data is indexed using Metaplex Digital Asset RPC infrastructure.
The @metaplex-foundation/digital-asset-standard-api
package can be use to interact with Metaplex DAS API.
npm install @metaplex-foundation/digital-asset-standard-api
import { dasApi } from '@metaplex-foundation/digital-asset-standard-api';
umi.use(dasApi());
Examples are provided here and you can learn more about this library's API by reading its generated TypeDoc documentation.
Note The plugin can be used with any RPC that supports the Metaplex DAS API specification. You might need to contact your RPC provider to "enable" the Metaplex DAS API on your endpoint.
mpl-core
Core assets and collections are also indexed by DAS. It is recommended to use this package in conjunction with the mpl-core-das if you are working with Core assets.
💡 You can test each method of the API using the OpenRPC playground.
Name | Description | Example |
---|---|---|
getAsset | Return the metadata information of a compressed/standard asset | ➡ |
getAssetProof | Return the merkle tree proof information for a compressed asset | ➡ |
getAssetsByOwner | Return the list of assets given an owner address | ➡ |
getAssetsByAuthority | Return the list of assets given an authority address | ➡ |
getAssetsByCreator | Return the list of assets given a creator address | ➡ |
getAssetsByGroup | Return the list of assets given a group (key, value) pair | ➡ |
searchAssets | Return the list of assets given a search criteria | ➡ |
⚠️ You should replace the
<ENDPOINT>
with the RPC endpoint to use.
