Sui is a Layer 1 blockchain with an object-oriented data model. This guide covers Sui-specific features when using Dfns wallets.

​
Object model

Sui uses an object-based model where everything is represented as an object, including:
  • Coins (fungible tokens)
  • NFTs
  • Custom objects
Dfns indexes all objects owned by your wallet.

​
Coin objects

When you receive SUI tokens, they are stored as coin objects. Multiple transfers result in multiple coin objects. Dfns automatically manages coin merging when needed for transfers.

​
Transfers

Use the Transfer Asset endpoint for Sui transfers:
  • Native SUI: Use kind: Native with amount in MIST (1 SUI = 1,000,000,000 MIST)
  • Coins: Use kind: Coin with the coin identifier

​
SDK integration

For full transaction control, use the Dfns SDK with @mysten/sui. See the Sui integration example.
