Sui’s Hashi targets Bitcoin finance with $500M in commitments

Sui says its Hashi Bitcoin finance network will begin a phased mainnet rollout in October, with more than $500 million in capital commitments from a coalition of more than 20 partners. The Sui Foundation’s announcement says the commitments are intended to support Bitcoin-backed markets on Sui as they come online. They are commitments, not a report that the full sum has already been deposited into Hashi.

Hashi was developed by Mysten Labs, a founding contributor to Sui. It is infrastructure for using Bitcoin as collateral in financial applications on Sui. The basic flow is: a user deposits native BTC into Hashi; Hashi mints hBTC on Sui against that Bitcoin; the user can then use hBTC in applications built on Sui. To exit, the user’s hBTC is burned and the corresponding BTC is released back to the Bitcoin network.

How does Hashi connect Bitcoin to Sui applications?

Bitcoin remains on the Bitcoin network while Hashi coordinates its use as collateral through Sui smart contracts, according to the announcement. The hBTC token represents the deposited Bitcoin on Sui, where applications can use it for lending, borrowing, credit, vaults and structured products. These financial products will be created and offered independently by third parties; Hashi provides the underlying infrastructure.

The distinction matters: hBTC lets applications act on the collateral without moving native Bitcoin into a Sui smart contract. Sui says Hashi uses multiparty computation security, smart contracts and a Guardian Layer. Its collateral uses a 2-of-2 multisignature structure that requires authorization from Hashi validators and the guardian. The guardian can add a check before BTC leaves the system and slow or stop suspicious movement.

What does the $500 million commitment cover?

Sui says the capital comes from Hashi’s launch coalition and is intended to give Bitcoin-backed markets liquidity as the phased rollout progresses. The announcement names Aftermath, Concrete and Fluid among providers expected to run Hashi vaults. It does not say that $500 million in Bitcoin is already locked in those vaults.

The network’s applications could let users borrow stablecoins against BTC, lend into onchain credit markets or use Bitcoin collateral in other products. Those uses depend on third-party applications and their integrations. As Cointelegraph reported, the launch coalition includes more than 20 companies, among them BitGo, Bullish, Cumberland, FalconX and Ledger.

How will institutions access Hashi?

Anchorage Digital has joined as a launch partner, adding two routes for institutional clients. Its Atlas infrastructure will support tri-party settlement for institutions using qualified custody, while its Porto wallet will provide a self-custody route. Anchorage also plans to provide stablecoin liquidity to Hashi, according to Sui.

The rollout is phased. Access will open as launch partners complete integrations, Sui said. The commitments give the network a stated capital base for its planned markets; actual activity will depend on which partners and applications go live and how much capital users put to work.
