The asset

Native currency of the Sui network (layer 1 smart-contract platform, Move language, delegated proof of stake) Issuer: Mysten Labs, Inc., a for-profit company conceived in 2021 by Evan Cheng, Adeniyi Abiodun, Sam Blackshear, George Danezis and Kostas Chalkias (former Meta employees, Diem project); the Sui Foundation, a non-profit entity described as independent, supports research and development.

SUI pays the gas and storage fees of the Sui network, is used for staking delegated to validators and gives a right to vote on protocol upgrades. The supply is capped at 10 billion SUI; 41.18% were unlocked as of October 7, 2026 according to Tokenomist (third-party source), with unlocks scheduled through 2030.

Why this verdict

  1. Permissible purpose : met. SUI pays the gas fees needed to execute transactions on the Sui network and gives a right to vote on protocol upgrades; the use is described by the official documentation (Sui Foundation).
    • « SUI is the asset denomination needed to pay the gas fees required to execute transactions or other operations on the network. » Sui (documentation, tokenomics) (2026-10-07)
    • « SUI tokens play an important role in governance by acting as a right to participate in onchain voting on issues such as protocol upgrades. » Sui (documentation, tokenomics) (2026-10-07)
  2. No riba : met. Holding SUI pays nothing in itself: staking rewards go only to tokens delegated to validators and come from the epoch's computation fees plus a temporary subsidy, with no loan. Staking is covered in autres_constats.
    • « The total amount of stake rewards is calculated as the sum of computation fees accrued throughout the epoch plus the epoch's stake reward subsidies. » Sui (documentation, tokenomics) (2026-10-07)
    • « Users of the network hold their own SUI, which they can delegate to validators of their choice as part of a validator's stake. » Sui (documentation, tokenomics) (2026-10-07)
  3. No gambling : met. A spot purchase is of a network's native token, used to pay gas; a US-listed fund (Grayscale Sui Staking ETF) holds SUI. It is not a contract on a price difference. SUI does not appear in the list of examples of “digital commodities” in the SEC-CFTC interpretation of March 17, 2026, a non-exhaustive list.
  4. No excessive gharar : met. The supply cap (10 billion), the absence of a free distribution (airdrop) and the principle of staggered unlocking are published; Mysten Labs and the Sui Foundation, identified entities, are still described as exerting influence over development. No anonymous party controlling issuance, the treasury or the keys was found; the composition of the foundation's governing bodies was not read (see lacunes).
    • « The total supply of SUI tokens on Mainnet is capped at 10,000,000,000 SUI. » Sui (documentation, tokenomics) (2026-10-07)
    • « Over 50% of SUI tokens are in the Community Reserve which is initially managed by the Sui Foundation. » Sui Foundation (blog) (2023-04-15)
  5. Real ownership : met. SUI is held in a personal wallet; delegated staking wraps the tokens in a “self-custodial” object with no transfer of ownership. The freezing of addresses by validators (May 2025, see autres_constats) falls under the network's governance.
  6. No fraud or manipulation : met. No sanction or deception toward SUI buyers was found: SUI appears neither in the SEC complaint against Binance (June 5, 2023) nor in the one against Coinbase (June 6, 2023), and the founders are named. The 100 largest wallets hold about 16% of circulating SUI (information, not a signal under the rule of October 6, 2026).
  7. Réseau ouvert et généraliste : met. un outil neutre
    • « Sui uses a delegated proof of stake (DPoS) consensus mechanism where validators lock a certain amount of SUI as collateral » Sui (documentation, tokenomics) (2026-10-07)

Tolerance case

T1. SUI is the native currency of a public, general-purpose network (payments, applications, games) on delegated proof of stake. Mysten Labs raised funds through investor sales, but SUI gives no right to any company revenue; no share of impermissible income is published or estimated (T2 case not quantifiable, not applied). The entry conditions for the full set of validators were not read (see lacunes).
