Exploration of Sui Data Application Scenarios
Introduction
Sui introduces a unique approach where all contracts, NFTs (Non-Fungible Tokens), and Coins can be perceived as Objects. This innovative storage structure operates on the basis of Objects, forming the foundation of Sui’s functionalities. In this article, we will explore the three core aspects related to Objects in Sui: NFT Collections, Token Values, and Package Contracts. Discover how Sui’s Object-based system revolutionizes the blockchain landscape.
- NFT (Collection)
NFTs are unique digital assets that represent ownership of a specific item, artwork, or collectible on the blockchain. In Sui, NFTs are treated as Objects, and their control is governed by a specific contract package. To find the NFT control contract package, we need to identify the package responsible for the minting functionality of the NFTs.
How to Find the NFT Control Contract Package?
To locate the NFT control contract package, we first need to find the package ID (object ID) associated with the NFT. For example, let’s say we want to find the bulk shark NFT package ID with the object ID

Querying All Move_Calls (Transactions) in the Package
Once we have the package ID, we can query all the move_calls (transactions) generated within that package:
<span style="font-weight:bold;color:#a71d5d;">select * from
</span><span style="color:#0086b3;">sui</span><span style="color:#323232;">.</span><span style="color:#0086b3;">move_calls
</span><span style="font-weight:bold;color:#a71d5d;">where</span><span style="color:#323232;"> move_package </span><span style="font-weight:bold;color:#a71d5d;">= </span><span style="color:#183691;">'0xee496a0cc04d06a345982ba6697c90c619020de9e274408c7819f787ff66e1a1'</span><span style="color:#323232;">;
</span><span style="color:#323232;">
</span>
Finding All NFT Objects in the Package
Alternatively, we can find all the NFT objects within the package using the corresponding NFT object type:
<span style="font-weight:bold;color:#a71d5d;">select * from
</span><span style="color:#0086b3;">sui</span><span style="color:#323232;">.</span><span style="color:#0086b3;">objects
</span><span style="font-weight:bold;color:#a71d5d;">where</span><span style="color:#323232;"> object_type </span><span style="font-weight:bold;color:#a71d5d;">= </span><span style="color:#183691;">'0xee496a0cc04d06a345982ba6697c90c619020de9e274408c7819f787ff66e1a1::suifrens::SuiFren<0x8894fa02fc6f36cbc485ae9145d05f247a78e220814fb8419ab261bd81f08f32::bullshark::Bullshark>'</span><span style="color:#323232;">;
</span><span style="color:#323232;">
</span>
- Token Value
Sui’s Coins are also treated as Objects, and each CoinType generates a unique Object ID. As a result, calculating balances requires grouping the same CoinType and Account Address.
How to Query Token Balances?
To query token balances, we need to group the same CoinType and Account Address together and calculate their total balance. For instance, the following SQL query retrieves the top 100 balances for the Sui Coin (CoinType: 0x2::coin::Coin<0x2::sui::SUI>):
<span style="font-weight:bold;color:#a71d5d;">select </span><span style="color:#62a35c;">sum</span><span style="color:#323232;">(storage_rebate) </span><span style="font-weight:bold;color:#a71d5d;">as</span><span style="color:#323232;"> balance, owner_address
</span><span style="font-weight:bold;color:#a71d5d;">from
</span><span style="color:#0086b3;">sui</span><span style="color:#323232;">.</span><span style="color:#0086b3;">objects
</span><span style="font-weight:bold;color:#a71d5d;">where</span><span style="color:#323232;"> object_type </span><span style="font-weight:bold;color:#a71d5d;">= </span><span style="color:#183691;">'0x2::coin::Coin<0x2::sui::SUI>'
</span><span style="font-weight:bold;color:#a71d5d;">group by</span><span style="color:#323232;"> owner_address, storage_rebate
</span><span style="font-weight:bold;color:#a71d5d;">order by</span><span style="color:#323232;"> balance </span><span style="font-weight:bold;color:#a71d5d;">desc
</span><span style="font-weight:bold;color:#a71d5d;">limit </span><span style="color:#0086b3;">100</span><span style="color:#323232;">;
</span><span style="color:#323232;">
</span>
- Package (Contract)
Top Contracts are determined by grouping packages based on the number of interactions they have.
How to Find Top Contracts?
To identify the top contracts, we group the packages by the number of move_calls (transactions) they generate. The following SQL query provides information on the top 100 contracts:
<span style="font-weight:bold;color:#a71d5d;">select </span><span style="color:#62a35c;">count</span><span style="color:#323232;">(</span><span style="color:#0086b3;">1</span><span style="color:#323232;">) </span><span style="font-weight:bold;color:#a71d5d;">as</span><span style="color:#323232;"> score, move_package
</span><span style="font-weight:bold;color:#a71d5d;">from
</span><span style="color:#0086b3;">sui</span><span style="color:#323232;">.</span><span style="color:#0086b3;">move_calls
</span><span style="font-weight:bold;color:#a71d5d;">group by</span><span style="color:#323232;"> move_package
</span><span style="font-weight:bold;color:#a71d5d;">order by</span><span style="color:#323232;"> score
</span><span style="font-weight:bold;color:#a71d5d;">desc
</span><span style="font-weight:bold;color:#a71d5d;">limit </span><span style="color:#0086b3;">100</span><span style="color:#323232;">;
</span><span style="color:#323232;">
