Security Procedures

The Custodian and the Prime Broker hold the Trust’s private keys in custody in accordance with the terms and provisions of the Prime Broker Agreement. Transfers to and from the Vault Balance and, where held in cold storage, the Trust’s Settlement Balance, require certain security procedures, including but not limited to, multiple encrypted private key shards, usernames, passwords and 2-step verification. Multiple private key shards held by the applicable Custodial Entity or Entities must be combined to reconstitute the private key to sign any transaction in order to transfer the Trust’s assets. Private key shards are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States.

As a result, if any one secure vault is ever compromised, this event will have no impact on the ability of the Trust to access its assets, other than a possible delay in operations, while one or more of the other secure vaults is used instead. These security procedures are intended to remove single points of failure in the protection of the Trust’s assets.

Transfers of SUI to the Vault Balance from the Settlement Balance will be available to the Trust once processed on the Sui Network, subject to the availability of the Prime Broker’s online platform. When SUI is credited to the Settlement Balance, certain movements to allocate the balance among (i) omnibus cold storage wallets and omnibus hot storage wallets on the Prime Broker’s platform; or (ii) omnibus accounts at Coinbase Connected Venues may not be viewable by the Trust via the Prime Broker’s online portal. In addition, on a monthly basis the Custodial Entities will provide the Sponsor with an account statement identifying the amount of cash and SUI in the Trust’s Accounts at the end of the period and listing all account activity during that period.

The process of accessing and withdrawing SUI from the Trust to redeem a Basket by an Authorized Participant follows the same general procedure as transferring SUI to the Trust to create a Basket by an Authorized Participant, only in reverse. See “Description of Creation and Redemption of Shares.”
