SuiSUI

Sui is a layer-1 blockchain designed for fast, low-cost applications such as DeFi, games and payments. It was created by Mysten Labs, a company founded in 2021 by former engineers from Meta's Diem blockchain project, including Evan Cheng, Adeniyi Abiodun, Kostas Chalkias and George Danezis. The Sui mainnet launched on May 3, 2023. SUI is the network's native token, and it is used to pay fees, to stake and to vote on governance.

Sui uses the Move programming language, which was originally created at Meta for Diem and has been adapted for Sui. Instead of tracking balances in accounts, Sui stores data as objects, each with an owner. Transactions that touch different objects can run in parallel, a design that is meant to deliver fast confirmation and high throughput.

Transactions that involve shared objects, such as swaps in a decentralized exchange, need a global order. Sui handles this with Mysticeti, a consensus protocol that reached the mainnet in 2024 and replaced the earlier Narwhal and Bullshark design. Sui is a delegated proof-of-stake network, so SUI holders can delegate their tokens to validators that secure the chain.

Developers build DeFi applications, games, NFTs and payment tools on Sui, and the network supports stablecoins, including native USDC.

SUI has a hard-capped maximum supply of 10 billion tokens. Only part of that supply was liquid at launch, and the rest is released on a multi-year unlock schedule, so the circulating supply grows over time. Current circulating and total supply figures are shown at the top of this page.

SUI began trading in May 2023 and fell to a low of about $0.36 in October 2023. It rose through 2024 and reached an all-time high above $5 in January 2025. You can see the all-time high and the full price history on the chart above.
