The world of blockchain is evolving rapidly, and staying ahead means having the right tools. We’re excited to announce that CoolWallet now supports the Sui blockchain, one of the most innovative and high-performance networks in the crypto space. This integration allows you to securely store, manage, and interact with SUI—the native token of the Sui network—as well as custom tokens built on its ecosystem.
Whether you're new to cryptocurrency or an experienced user exploring next-gen decentralized applications (DApps), CoolWallet provides a seamless, secure, and user-friendly experience tailored for the Sui blockchain. Read on to discover what makes Sui stand out, why CoolWallet is the ideal companion for your Sui journey, and how to get started today.
What Is Sui Blockchain?
Sui is a cutting-edge Layer-1 blockchain designed for speed, scalability, and developer efficiency. Developed by Mysten Labs, a team of former Meta engineers, Sui leverages advanced technologies like parallel transaction processing and horizontal scaling to deliver unmatched performance—ideal for gaming, DeFi, NFTs, and social applications.
At its core, Sui uses the Move programming language, which takes a unique object-centric approach rather than the traditional account-based model used by most blockchains. In this system, digital assets and smart contracts are treated as individual objects with specific ownership rules and permissions. This design enhances security by eliminating common vulnerabilities such as reentrancy attacks and simplifies how developers build complex DApps.
Thanks to its innovative architecture, Sui can process over 100,000 transactions per second (TPS)—a benchmark that sets new standards in blockchain efficiency and responsiveness. This makes it an attractive platform for high-throughput applications where speed and reliability are critical.

Why Sui Blockchain Stands Out
In a crowded field of Layer-1 blockchains like Ethereum, Solana, and Polkadot, Sui distinguishes itself through a powerful combination of speed, security, and developer flexibility.
Key Advantages of Sui:
- Parallel Transaction Execution: Unlike Ethereum’s sequential processing model—which often leads to network congestion and high gas fees—Sui processes multiple transactions simultaneously. This results in faster confirmations and lower costs.
- High Throughput & Low Latency: With support for over 100,000 TPS, Sui outperforms most existing networks in raw performance.
- Stability Over Competition: While Solana has faced periodic outages under load, Sui’s architecture is built for consistent uptime and resilience.
- Interoperability Without Complexity: While Polkadot emphasizes cross-chain communication, Sui achieves high functionality within a single chain without sacrificing simplicity.
Growing Ecosystem Momentum
Sui isn’t just technically impressive—it’s gaining real-world traction:
- The SUI token reached an all-time high of $5.35 in early January 2025, reflecting strong investor confidence.
- As of January 2025, the Total Value Locked (TVL) in Sui’s DeFi ecosystem exceeded $1.96 billion, signaling robust adoption across lending protocols, decentralized exchanges, and yield-generating platforms.
This rapid growth underscores Sui’s potential to become a leading infrastructure layer for next-generation Web3 applications.
