Editorial policySui is a high-performance Layer-1 blockchain built by ex-Meta engineers using the Move programming language — offering a novel object-oriented execution model, sub-second finality, and one of the fastest-growing DeFi ecosystems in 2024–2025 with native DEXs, lending protocols, and a burgeoning NFT and gaming ecosystem.
Sui is a Layer-1 blockchain developed by Mysten Labs, founded in 2021 by Evan Cheng, Adeniyi Abiodun, Kostas Chalkias, George Danezis, and Sam Blackshear — all former members of Meta's Diem (formerly Libra) blockchain project. Sui launched its mainnet in May 2023 and rapidly established itself as one of the fastest-growing new blockchain ecosystems, reaching billions in TVL within its first two years and consistently ranking among the most active chains by daily transactions.
Sui's foundational distinction is its use of the Move programming language — a resource-oriented smart contract language originally developed for Diem — combined with a novel object-centric execution model. Rather than treating blockchain state as a set of accounts with balances (Ethereum's model), Sui treats everything as an object with ownership properties. This allows Sui to parallelise transaction execution for transactions that touch different objects, dramatically increasing throughput without sacrificing safety.
Move was designed from the outset with financial applications in mind — its type system makes it impossible to accidentally duplicate or lose assets (digital resources can only be moved, not copied), a property that eliminates entire categories of smart contract vulnerabilities that have led to hundreds of millions in losses on EVM chains. Sui's variant of Move (Sui Move) extends the original language with the object model, making objects — not accounts — the fundamental unit of state.
The practical consequence of Sui's execution model is performance: because unrelated transactions (those touching different objects) can be processed in parallel without consensus coordination, Sui can achieve throughput that scales with additional hardware rather than being constrained by a serial execution bottleneck. In benchmarks, Sui has demonstrated 297,000 transactions per second in controlled conditions — though real-world DeFi usage produces lower figures due to transactions that share state and require sequential processing.
Cetus Protocol is the leading DEX on Sui, implementing a concentrated liquidity AMM similar to Uniswap V3. Cetus allows liquidity providers to specify price ranges for their capital, improving capital efficiency relative to traditional constant-product AMMs. The CETUS token provides governance rights and staking rewards. Turbos Finance is a competing concentrated liquidity DEX that has attracted significant trading volume, and together Cetus and Turbos form the core DEX infrastructure for the Sui DeFi ecosystem.
Scallop Lend is Sui's primary lending protocol, offering isolated lending markets for SUI, USDC, USDT, wBTC, and other assets. Scallop's design emphasises risk isolation — each market operates independently, preventing cross-market contagion in the event of a bad debt event. Navi Protocol is a competing lending and yield protocol that adds automated portfolio management features on top of core lending functionality.
Aftermath Finance and DeepBook are Sui-native protocols providing additional DEX and liquidity infrastructure. DeepBook, notably, is a shared on-chain order book — a primitive that is difficult to build on Ethereum due to its sequential execution model but becomes feasible on Sui's parallel execution architecture, enabling more sophisticated market-making strategies.
Sui's ecosystem growth has been exceptional for a network that launched in 2023. The combination of Meta alumni credibility, technical innovation in the Move language and object model, and strong venture backing (Mysten Labs raised $300 million in a Series B before mainnet) created favourable conditions for developer adoption and protocol deployment.
The SUI token serves as the network's gas asset and staking token, with validators and delegators staking SUI to participate in consensus and earn staking rewards. Sui's gas pricing model is designed to remain stable relative to computational work even as SUI's price fluctuates — a design choice that protects DeFi protocols from fee spikes during market volatility. The network's rapid TVL growth and active NFT and gaming ecosystems position Sui as one of the most important new Layer-1 environments in DeFi.

Sui DeFi Ecosystem DeFi Ecosystem hosts a growing ecosystem of DeFi applications including decentralised exchanges (DEXs), lending protocols, yield aggregators, liquid staking solutions, and stablecoins. The total value locked across these protocols can be tracked on DeFiLlama's Sui DeFi Ecosystem DeFi Ecosystem chain page.
Assets can be bridged to Sui DeFi Ecosystem DeFi Ecosystem via official cross-chain bridges or third-party aggregators such as Stargate, Across Protocol, or Li.Fi. Always use official or audited bridges, verify contract addresses independently, and start with a small test transfer before moving larger amounts.
Sui DeFi Ecosystem DeFi Ecosystem has a native token used to pay transaction gas fees and, in many cases, participate in network governance or staking. Check the official Sui DeFi Ecosystem DeFi Ecosystem documentation for the current token ticker, total supply, and staking yield.
Transaction costs on Sui DeFi Ecosystem DeFi Ecosystem depend on network congestion and the complexity of the operation. Layer-2 networks typically offer significantly lower fees than Ethereum mainnet. Current gas prices can be checked via the network's block explorer or a gas tracker tool.
Sui DeFi Ecosystem DeFi Ecosystem has its own architecture and may offer Ethereum compatibility via an EVM-compatible execution environment. Check the official documentation for details on cross-chain interoperability and supported standards.
Sui DeFi Ecosystem DeFi Ecosystem is designed to process transactions quickly, with block times and throughput significantly higher than Ethereum mainnet for Layer-2 solutions. Performance specifications including transactions per second (TPS) and average finality time are published in the official Sui DeFi Ecosystem DeFi Ecosystem documentation.
Sui DeFi Ecosystem DeFi Ecosystem is distinguished by its specific consensus mechanism, virtual machine, developer tooling, and ecosystem focus. Key differentiators may include throughput, fee levels, decentralisation trade-offs, and the maturity of its DeFi ecosystem. Reviewing independent comparisons on DeFiLlama and Messari provides objective data.
To begin using Sui DeFi Ecosystem DeFi Ecosystem, install a compatible wallet (MetaMask works for EVM-compatible chains), add the Sui DeFi Ecosystem DeFi Ecosystem network via its official RPC settings, and acquire the native token for gas. Most networks have a dedicated faucet for test tokens on their testnet. Visit the official Sui DeFi Ecosystem DeFi Ecosystem website for a step-by-step onboarding guide.
Arbitrum, Base, and Optimism are the three dominant Ethereum Layer 2 networks for DeFi in 2026. Each has different liquidity depth, fee structures, DeFi ecosystem maturity, and decentralisation trade-offs. This guide helps you choose the right L2 for your needs.
Ethereum and Solana are the two dominant smart contract platforms for DeFi in 2026. They represent fundamentally different design philosophies — Ethereum prioritises decentralisation and security, Solana prioritises speed and low cost. This guide compares both for DeFi users.
