We checked this claim: is it true that
Sui would begin a phased mainnet rollout of its Hashi Bitcoin finance network later in October?
Mysten Labs and the Sui Foundation confirmed Hashi will launch in October 2026 backed by more than $500 million in partner capital commitments
Sui developer Mysten Labs secures $500 million for Bitcoin loans
A phased rollout of the Hashi lending network begins in October with institutional backing, but market impact hinges on actual borrower demand.
In a nutshell
Sui network developer Mysten Labs is rolling out Hashi, a decentralized finance framework that allows investors to borrow against their Bitcoin reserves without selling them, backed by over $500 million in capital commitments from more than 20 institutional firms. While the participation of regulated entities like Anchorage Digital provides compliant custody and settlement, market observers caution that pledged liquidity represents balance sheet commitments rather than active borrowing, leaving the true scale of adoption dependent on actual loan demand once mainnet vaults open.
Highlights
- Mysten Labs scheduled a phased mainnet launch for the Hashi Bitcoin finance network in October 2026.
- More than 20 digital asset firms committed over $500 million in pre-launch capital to support the protocol.
- Federally chartered digital asset bank Anchorage Digital joined as a day-one custody and settlement partner.
- Hashi issues hBTC tokens against locked native Bitcoin to enable lending and borrowing collateralization without asset sales.
- Market analysts noted the $500 million represents pledged partner capital rather than active on-chain total value locked.
From the Editor’s Diary
Headline capital commitments signal institutional interest, but a lending platform's true market footprint is measured only when pledged balance sheets turn into active borrower debt.
Who's involved
Mysten Labs
primary software development firm behind the Sui Layer-1 blockchain
goal → aims to expand Sui's network activity and draw institutional Bitcoin liquidity
Anchorage Digital
federally chartered digital asset bank and custody company
goal → aims to supply institutional settlement rails and regulated storage for Bitcoin decentralized finance
Bitcoin holders and institutions
investment funds and corporate treasuries holding long-term Bitcoin balances
goal → seeking low-risk yields and credit against Bitcoin deposits without selling their underlying tokens
In short
Bitcoin holders can soon borrow cash and earn yields against their cryptocurrency reserves without having to sell them first. Sui developer Mysten Labs will begin rolling out Hashi, a native Bitcoin-backed decentralized finance system, across its blockchain network in October 2026. Hashi lets depositors lock native Bitcoin into regulated vaults, receiving a digital receipt called hBTC on Sui that can serve as collateral in decentralized lending and yield markets.
The initiative makes an immediate influx of institutional liquidity into the Sui ecosystem likely over the coming months. A consortium of over 20 digital asset firms, including BitGo, FalconX, Bullish, and Cumberland, has pledged more than $500 million in pre-launch capital, while US-chartered crypto bank Anchorage Digital has signed on as a launch partner to provide federally supervised custody and settlement services.
Whether this capital actually sparks a sustained lending boom remains uncertain because committed reserves are not the same as active debt. Pledged capital represents liquidity guarantees from balance sheets, rather than operational deposits or completed loans. Hashi's ultimate footprint will depend on how much of that committed sum converts into open borrowing positions once mainnet lending vaults become operational.

How it unfolded
Sui Foundation announces Hashi mainnet launch timeline and backing
The Sui Foundation and Mysten Labs announced at Sui Basecamp on October 8, 2026, that the Hashi Bitcoin lending network will start a phased mainnet launch during October 2026, supported by more than $500 million in institutional backing.
Institutional coalition forms around Bitcoin lending
The launch announcement triggered immediate institutional alliances across trading desks and custodian banks. Anchorage Digital entered the project to manage three-party settlements and wallet connections, while credit platforms such as Fluid prepared to run the underlying loan pools. By October 9, market analysis separated these headline figures from realized usage, emphasizing that the $500 million represents partner pledges rather than active decentralized finance deposits.
Where things stand
Mysten Labs is preparing for the staged rollout of Hashi across October 2026, using an architecture that issues hBTC tokens against audited custody reserves. Market participants are watching to see how quickly partner firms transfer their pledged assets into live lending pools, and whether institutional borrowing demand materializes once the platform opens.
