The Sui blockchain is experiencing unprecedented momentum. With its native token surging and Total Value Locked (TVL) surpassing $500 million, the ecosystem is entering what many are calling its "breakout year." At the heart of this growth stands **Scallop**, a leading DeFi protocol with over $100 million in TVL—solidifying its position as a foundational pillar in Sui’s rapidly expanding landscape.
To explore the drivers behind this surge, a recent Twitter Space hosted by BlockBeats featured key players shaping Sui’s future: Kriss, CEO of Scallop; Cyn, Head of Asia Ecosystem at Sui Foundation; Irwin, DeFi Lead at OKX; and Mr. Block, a prominent crypto KOL. The discussion unpacked Sui’s technological edge, Scallop’s strategic role, and how incentive programs are fueling adoption—while offering insights into what comes after the initial hype.
Why Sui? Unpacking the Chain’s Core Advantages
Sui isn’t just another high-performance blockchain—it’s redefining how smart contracts and digital assets interact on-chain.

Speed Through Parallel Execution
One of Sui’s most significant innovations lies in its consensus mechanism. Unlike traditional blockchains that process transactions sequentially, Sui uses parallel execution to handle multiple transactions simultaneously—provided they don’t conflict. This means faster finality, lower fees, and near-instant settlement times, making it ideal for real-time applications like gaming and decentralized exchanges (DEXs).
As Kriss explained, Sui’s Move-based object model allows transactions to “jump the queue” when independent, eliminating bottlenecks common on EVM chains.
Move Language: Security by Design
Security remains a top concern across DeFi, especially after countless exploits on Ethereum and Solana. Sui addresses this through Move, a programming language originally developed by Meta’s Diem team.
Move enforces strict resource ownership rules—assets can’t be duplicated or accidentally deleted. Every permission check is baked into the framework, reducing developer burden and minimizing vulnerabilities.
“With Move, you focus on business logic—not reinventing access controls,” said Kriss. “It’s like having 80–90% of security checks already built-in.”
This contrasts sharply with Solidity, where developers must manually implement safeguards—a major source of bugs and exploits.
Object-Centric Architecture
While most blockchains use account-based models, Sui treats every asset as an independent object—similar to NFTs. Your USDC isn’t just a balance in a central contract; it’s your personal object, owned and controlled directly.
This design eliminates single points of failure. Even if a lending protocol is compromised, core assets remain safe because they’re not pooled in a central contract.
Irwin highlighted how this architecture enhances composability: “Each token being an object opens doors for innovation in gaming, identity, and DeFi.”
Scallop: More Than Just a Lending Protocol
While often categorized as a lending platform on DefiLlama, Scallop offers far more than basic borrowing and lending.
It serves as a comprehensive DeFi infrastructure layer for the Sui ecosystem, providing:
- Multi-asset lending and borrowing
- Flash loans
- Swap and bridge UI tools
- Developer SDKs (SuiKit)
- Native yield-bearing tokens (S Coin)
Built for Safety and Composability
Scallop leverages Sui’s Move language to prevent common attack vectors:
- No fake address attacks: Impossible due to Move’s strict object ownership.
- Oracle manipulation resistance: Scallop uses Pyth Network with plans to integrate Switchboard and Super Oracle in a modular “X-Oracle” consensus layer.
- Open-source transparency: It’s the only fully open-source lending protocol on Sui.
Its risk model combines elements from Compound V3, Solend V2, and Euler Finance—featuring a three-tier interest rate model and soft liquidations. Instead of selling off all collateral during undercollateralization, Scallop only recovers enough to restore health—preserving user assets.
Empowering Developers with SDKs
Scallop’s SuiKit is now the largest unofficial TypeScript SDK on Sui—used by wallets like Suiet and platforms like Typus Finance.
Developers can integrate flash loans with just four lines of code—compared to 78+ lines required on Aave. This dramatically lowers the barrier to entry for new projects building on Sui.
The Role of Incentives: Fueling Early Adoption
User incentives have played a crucial role in accelerating Sui’s TVL growth.
Dual-Layer Reward System
Scallop runs its own incentive program alongside Sui Foundation initiatives:
- Lending APR + S Coin staking rewards: Users earn base interest from borrowers, plus auto-compounded yields from staking their $S Coin.
- Average APR: 15–20%
- No lock-up period—full liquidity retained
For borrowers, the math gets even more compelling:
- Borrowing SUI earns up to 7.13% APR in rewards, while paying only ~0.73% in interest
- Net gain: ~6.4% return just for borrowing
👉 See how smart incentives are driving DeFi growth across new ecosystems.
Leveraged Yield Strategies
Advanced users are combining strategies for higher returns:
- Convert SUI → fsUI (liquid staking token with ~4% yield)
- Deposit fsUI as collateral
- Borrow SUI at negative net cost
- Restake borrowed SUI or deposit into other yield-generating protocols
This creates a leveraged yield loop, amplifying returns without requiring additional capital.
Active Airdrop Campaign
Scallop is currently running a points-based pre-launch airdrop campaign:
- Users earn “Pearls” based on activity
- Pearls will convert to native tokens post-launch
- Final phase ongoing—last chance to qualify
Cyn confirmed that multiple DeFi projects plan token launches in Q1–Q2 2025, suggesting more airdrops are imminent.
Additionally, Sui Foundation continues its Odyssey series—gamified onboarding quests—and teased upcoming ZK-focused campaigns like ZK Send.
Beyond DeFi: Building a Sustainable Ecosystem
While DeFi dominates today, long-term success depends on diversification.
Gaming and IP: The Next Frontier
Cyn emphasized that gaming is a strategic priority for Sui:
- Over 40 game partners onboarded
- Major titles like NHN’s mobile game and Soul Reaper Samurai expected in 2025
- Potential for in-game integration of DeFi features (e.g., Scallop-powered lending)
Just as NFTs propelled Solana in 2021, gaming could be Sui’s next catalyst—driving sustained user engagement beyond yield chasing.
The Challenge of Fragmentation
Mr. Block raised concerns about liquidity fragmentation across chains:
“There are 30+ major lending protocols—one per chain. Where does liquidity come from? VC funding is stretched thin.”
He warned that identical codebases deployed across chains create unsustainable competition—unless protocols find unique value propositions.
Scallop’s differentiation lies not in novelty, but in execution quality, team strength, and ecosystem integration.
Post-Incentive Survival: What Comes Next?
All good things end—including generous reward programs. So how do protocols retain users?
Flywheel Effect Through Composability
Kriss envisions Scallop evolving into infrastructure for higher-level protocols:
- Projects like Kai Finance, Typus Finance, and Sui Pearl are already building on Scallop
- These could become future innovators—powered by Scallop’s secure base layer
- Similar to how Orca supports Jupiter on Solana
This creates a self-reinforcing cycle: base-layer protocols enable new apps → apps attract users → users generate fees → fees sustain base-layer development.
Focus on Security and Risk Management
Irwin stressed that survival during bear markets hinges on:
- Robust risk controls
- Smooth liquidation mechanisms
- Proven resilience through black swan events
Protocols like Uniswap and Curve endured past crashes—earning institutional trust. Scallop aims to follow that path.
Native Stablecoins & Cross-Chain Bridges
Cyn highlighted upcoming developments:
- Native USDC/USDT integration will unlock new levels of TVL and trading volume
- Planned native bridge between Ethereum and Sui to ease asset transfers
- Development of ZK Login and ZK Send for enhanced privacy and usability
These upgrades will reduce reliance on third-party bridges and improve user experience.
