Sui Module

The Sui module parses transactions for the Sui blockchain, which uses the Move programming language and an 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.
