Key Takeaways Hashi plans a phased mainnet launch later in October. More than $500 million has been committed across its launch coalition. Deposited BTC supports hBTC, the collateral token us
The Sui Foundation said Hashi will begin a phased mainnet rollout later in October. Its coalition includes more than 20 partners, with Aftermath, Concrete and Fluid among the providers expected to run vaults. Hashi supplies the infrastructure, while third parties create the lending, borrowing and other financial products that users will actually access.
The coalition had already expanded with Cumberland, Fluid and SwissBorg ahead of Hashi’s July global testnet. Mainnet now moves that work into a setting where lenders need to supply assets, borrowers need to accept the terms, and vaults need to function under live conditions.
Hashi begins with a Bitcoin deposit. A user sends BTC to a Hashi-generated Bitcoin address; after the required confirmations and delay, the system mints an equivalent amount of hBTC on Sui. That hBTC can then serve as collateral in a lending or other financial application.
BTC stays on the Bitcoin ledger, while hBTC gives the depositor a usable position inside Sui applications. Releasing that BTC requires authorization through Hashi’s MPC committee and Guardian layer, according to the project’s technical documentation. The arrangement moves control away from a single ordinary wallet and into a shared signing structure.
Participation in the committee requires Sui validators to separately register and operate the necessary services; it does not automatically include the entire validator set. On withdrawal, the matching hBTC is burned on Sui before the committee and Guardian authorize a Bitcoin transaction back to the user’s chosen address, less network fees.
Once BTC is represented by hBTC, the next question is who can use that collateral under their own custody rules. Anchorage’s role addresses that part of the launch.
Institutions do not all work under the same custody model. A public company may require regulated collateral arrangements, while a crypto-native fund may prefer to manage its own wallet and interact with applications directly.
Anchorage Digital has set out two ways for clients to reach Hashi. Atlas, its settlement and tri-party collateral infrastructure, is designed for organizations operating under qualified-custody and compliance requirements. Anchorage says assets can remain in qualified custody while being mobilized as collateral.
Its institutional self-custody wallet, Porto, provides the other route for clients seeking direct access to Hashi and the applications built around it. Those choices broaden the range of potential participants, yet the custody path alone does not establish the rate, collateral ratio or liquidation terms of a future loan.
$500M is committed capital, not a live lending balance
Confirmed: Hashi says more than $500 million has been committed across its launch coalition.
Still unknown: how much reaches mainnet at launch, which assets are supplied to each market and how much liquidity borrowers can access.
Committed capital does not automatically become borrowable liquidity. A borrower needs lenders to supply the asset they want to borrow, whether that is a stablecoin or another token. The Sui Foundation has not published a partner-by-partner allocation or a timetable for deploying the committed capital.
That leaves several practical questions for the first live markets: which assets are available, how much collateral they require, what interest rates apply and how liquidations work when Bitcoin’s price falls. The answers will differ between applications because the financial products are being created by independent providers.
Sui says access will expand as launch partners complete their integrations. The resulting loan terms and liquidity depth will show whether the network can serve Bitcoin holders who want financing without selling their holdings.

Hashi is aimed at holders that want to use Bitcoin without moving it onto another blockchain or abandoning the custody controls that govern their balance sheets. Its mainnet design combines Bitcoin-held collateral, Sui-side hBTC and different access routes for regulated institutions and self-directed market participants.
For those users, the size of the coalition is only a starting point. Borrowing costs, collateral requirements, withdrawal reliability and stablecoin depth will determine whether Bitcoin-backed finance on Sui becomes a practical treasury tool.
