KuCoin’s Web3 Wallet now officially supports Sui mainnet assets, allowing users to hold, send, receive and manage tokens, NFTs and other assets, connect to Sui-based decentralized applications and use cross-chain swaps without leaving the self-custodial wallet. The integration reduces the need to switch between wallets, bridges or third-party tools and broadens access to Sui’s ecosystem. Sui, developed by Mysten Labs and launched as a mainnet in 2023, highlights transaction finality in under one second and positions its horizontal-scaling and low-latency design for applications including gaming, decentralized finance and social platforms. KuCoin first listed SUI for spot trading in May 2023 and enabled USDC deposits on the Sui network in October 2024. The wallet expansion forms part of KuCoin’s broader multi-chain push, which included support for Robinhood Chain, 0G, Monad and HyperEVM during 2025 and into 2026. There were no immediate signs of a significant change in SUI’s price or trading volume after the announcement.
