SUI (SUI): how object-based design enables DeFi experiences this year

Explore how SUI’s object-based architecture is reshaping DeFi in 2025, offering faster transactions and new financial primitives.

  • Object‑oriented smart contracts on SUI unlock composable DeFi building blocks.
  • Higher throughput and lower fees create more accessible liquidity pools.
  • Real‑world asset tokenization gains traction with platforms like Eden RWA.

Sui, a Layer‑1 blockchain launched by Mysten Labs, has gained attention for its unique object-based design that diverges from the conventional account‑based model of Ethereum. In 2025, DeFi developers are increasingly turning to Sui’s architecture to create more efficient, composable protocols and to integrate real‑world assets (RWAs) into Web3 ecosystems.

For crypto‑intermediate retail investors, understanding how this technical shift translates into new investment opportunities and risk profiles is crucial. The article examines the core mechanics of object‑based smart contracts, evaluates their impact on DeFi primitives such as liquidity pools and synthetic derivatives, and explores how platforms like Eden RWA are leveraging Sui’s capabilities to democratize luxury real‑estate ownership.

By the end of this piece you will know:

  • The fundamental differences between object‑based and account‑based blockchains.
  • How Sui’s design enables faster, cheaper DeFi interactions.
  • The practical implications for tokenized real‑world assets and potential use cases.

Background: Object-Oriented Smart Contracts in 2025

Sui introduces a novel data model where the primary unit of state is an “object” rather than an account balance. Each object has its own ownership, capabilities, and lifecycle governed by a Move‑based language that enforces fine-grained access control.

In contrast to Ethereum’s account model—where every transaction updates a single global state map—Sui partitions the ledger into isolated objects. This reduces contention, allowing parallel execution of transactions that touch different objects. The result is higher throughput (up to 30k TPS in testnets) and lower gas costs.

Regulatory bodies such as the SEC and MiCA are increasingly scrutinizing blockchain innovations that promise greater transparency and reduced systemic risk. Sui’s deterministic object model aligns well with auditability requirements, making it attractive for compliant DeFi protocols that seek to bridge institutional trust with decentralized execution.

How It Works: From Objects to Financial Primitives

The workflow on Sui can be broken down into three stages:

  • Object Creation and Ownership: A developer deploys a Move module that defines an object type (e.g., LiquidityPool). Upon deployment, the module creates an instance of this object with initial parameters.
  • Capability Management: Each object carries capabilities—permissions that can be transferred or revoked. For example, only the pool’s admin capability may mint new liquidity tokens.
  • Transaction Execution: When a user interacts (e.g., swaps tokens), the transaction references the relevant objects. Since objects are isolated, Sui can execute multiple such transactions concurrently, dramatically improving scalability.

Key actors include:

  • Issuers: Protocol developers who deploy modules and create object instances.
  • Custodians: Off‑chain entities that hold collateral backing tokenized assets.
  • Investors: End users who transact with protocol objects via wallets like MetaMask or Ledger.

Market Impact & Use Cases

The shift to object‑based contracts opens several new DeFi use cases:

  • Composable Liquidity Pools: Protocols can create nested pools where each sub‑pool is an object, enabling dynamic fee structures and multi‑asset swaps without global state locks.
  • Synthetic Derivatives: Synthetic tokens can be minted as objects tied to real‑world asset indices. Their value updates via oracle feeds, while the underlying synthetic contract remains a distinct object that can be transferred or burned independently.
  • Tokenized Real‑World Assets (RWAs): Asset owners create an RWA token object representing fractional ownership. Smart contracts enforce dividend distributions and voting rights as separate objects, ensuring clear separation of duties.

Transaction Speed Minutes to hours Milliseconds to seconds
Fee Structure Banking fees + brokerage Gas < 0.1 USD per tx

Risks, Regulation & Challenges

While object‑based design offers clear benefits, several risk factors remain:

  • Smart Contract Vulnerabilities: Move is still a young language; bugs in capability handling can lead to loss of ownership or unauthorized minting.
  • Custodial Risk for RWAs: Physical assets are held off‑chain by custodians. A breach or insolvency could jeopardize token holders.
  • Liquidity Constraints: Despite higher throughput, liquidity for niche objects (e.g., luxury villa tokens) may still be thin, affecting price discovery.
  • Regulatory Uncertainty: Jurisdictions vary on recognizing blockchain‑issued ownership. Sui’s deterministic model helps compliance, but cross‑border operations may still face legal hurdles.

Outlook & Scenarios for 2025+

Looking ahead, three scenarios emerge:

  • Bullish: Wider institutional adoption of Sui protocols leads to robust secondary markets and increased tokenized asset listings.
  • Bearish: A high‑profile Move language exploit undermines confidence in object‑based contracts, causing a shift back to account‑based chains.
  • Base Case: Steady incremental growth; more DeFi protocols migrate to Sui while maintaining parallel operations on Ethereum for liquidity.

Retail investors should assess whether the protocol’s governance structure aligns with their risk tolerance and whether the underlying asset (e.g., a luxury villa) has sufficient demand to sustain price stability.

Eden RWA: A Concrete Example of Tokenized Real Estate on Sui

Eden RWA is an investment platform that democratizes access to French Caribbean luxury real estate by combining blockchain with tangible, yield‑focused assets. The platform uses Ethereum’s ERC‑20 tokens for fractional ownership but integrates with the Sui network’s object model to enhance efficiency and composability.

  • ERC‑20 Property Tokens: Each luxury villa (e.g., in Saint‑Barthélemy or Martinique) is represented by a dedicated ERC‑20 token issued by an SPV (SCI/SAS).
  • SPVs and Custody: The real property is owned by a special purpose vehicle, ensuring clear legal ownership separate from the on‑chain tokens.
  • Rental Income in Stablecoins: Rental payments are automatically distributed to token holders in USDC via audited smart contracts.
  • Quarterly Experiential Stays: A quarterly draw selects a token holder for a free week in one of the villas, adding utility beyond passive income.
  • DAO‑Light Governance: Token holders vote on key decisions—renovation budgets, sale timing—without imposing heavy governance overhead.

Eden RWA’s architecture demonstrates how object‑based contracts can be layered over existing ERC‑20 standards to create transparent, yield‑generating real‑world asset products that appeal to both retail and institutional participants.
