# Sui

> Object model, Move calls, and programmable transactions

The Sui module handles the Move programming language and Sui's object-centric data model.

## Architecture overview

### Transaction model

* **Encoding**: BCS (Binary Canonical Serialization)
* **Object-based**: Resources are objects with unique IDs
* **Move Language**: Type-safe smart contract language
* **Gas Model**: Storage and computation fees

### Key components

The Sui parser handles:

* Object transfers
* Move function calls
* Coin operations (split, merge)
* Programmable transactions
* Package publishing

## Transaction types

### Programmable transactions

Sui's programmable transactions allow multiple operations in a single transaction:

* Multiple Move calls
* Object transfers
* Coin operations
* All executed atomically

### Object model

* **Owned Objects**: Belong to a specific address
* **Shared Objects**: Accessible by multiple transactions
* **Immutable Objects**: Read-only after creation

## Visualization strategy

* **Command Sequence** - Show programmable transaction commands as a sequence of operations
* **Object Information** - Display object IDs and ownership when relevant to the transaction
* **Gas Objects** - Show gas payment details including storage rebates

## Implementation details

Source code available at:

* [Sui Parser](https://github.com/anchorageoss/visualsign-parser/tree/main/src/chain_parsers/visualsign-sui)

## Common operations

* **SUI Transfer** - Transfer of native SUI tokens between addresses
* **Object Transfer** - Moving owned objects from one address to another
* **Move Function Call** - Invoking functions in deployed Move modules
* **Coin Split/Merge** - Operations to divide or combine coin objects
