Sui’s Hashi targets October launch with $500M committed

Sui said on October 8 that Hashi, its Bitcoin finance network, would begin a phased mainnet rollout later this month with more than $500 million in capital commitments from its launch coalition. The Sui Foundation’s announcement says the commitments are intended to support lending, borrowing and other Bitcoin-backed markets. The figure is committed capital, not a report of $500 million in Bitcoin already deposited or active in those markets.

The launch also adds Anchorage Digital, which says it will offer institutional clients routes into Hashi through tri-party settlement and self-custody, and plans to provide stablecoin liquidity. The Cointelegraph report likewise describes the rollout as phased and lists more than 20 coalition members, including BitGo, Bullish, Cumberland, FalconX and Ledger. The announcement does not break down the $500 million by partner or say how much will be available on day one.

How will Hashi connect Bitcoin to Sui applications?

Hashi is designed to let Bitcoin serve as collateral in applications on Sui without moving the underlying BTC off the Bitcoin network. According to Sui, a user deposits BTC into Hashi and receives hBTC on Sui; when the user exits, hBTC is burned and the BTC is released back to Bitcoin. Sui says third parties will build and offer the financial products, including lending, credit, vaults and structured products.

That structure differs from the wrapped or synthetic Bitcoin products that already represent BTC on other networks. In its March introduction of Hashi, Sui argued those products had been slow to gain institutional traction because of concerns about collateral transparency. Hashi’s proposed distinction is that BTC remains on Bitcoin while its collateral use is coordinated through Sui contracts. But hBTC still has to represent that collateral across two networks, so users and lenders will depend on the bridge and custody mechanisms working as intended.

What does the $500 million commitment establish?

It signals partner backing for the launch, but it does not by itself establish market depth, borrowing demand or the amount of BTC that will be deposited. Sui says vault providers such as Aftermath, Concrete and Fluid will support markets, while Anchorage plans to add stablecoin liquidity. The mix matters: BTC collateral alone cannot fund loans denominated in stablecoins, and announced commitments only become useful liquidity when partners complete integrations and make capital available.

Anchorage’s two access routes address different operating preferences. Its Atlas settlement infrastructure is intended for institutions that need qualified custody and tri-party collateral arrangements; its Porto wallet offers a self-custody route. That could widen access beyond crypto-native firms, while adding dependencies on custody operations and partner integrations. The announcement describes Hashi’s security model as using multi-party computation, Sui smart contracts and a Guardian Layer, with a two-of-two multisignature structure requiring authorization from Hashi validators and the guardian. Sui says the guardian can slow or stop suspicious collateral movements. These controls describe the design; they do not establish how it will perform under live market stress.

Which launch signals will show whether Hashi is gaining traction?

The first test is whether the phased rollout brings deposits and usable lending markets online as scheduled. After launch, the clearest measures will be BTC deposited, hBTC in circulation, stablecoin liquidity available to borrowers, and actual borrowing and lending activity. A $500 million commitment gives Hashi a substantial announced starting point compared with a launch that has to attract liquidity one deposit at a time. Whether that translates into sustained use will depend on how much capital partners deploy, how safely users can move in and out, and whether third-party applications offer terms that attract Bitcoin holders without obscuring the risks.
