Sui Hashi Bitcoin Finance is moving toward its phased mainnet rollout with more than $500 million in capital commitments from launch partners. Sui Foundation announced on October 8 that the network will begin launching later this month, with Anchorage Digital joining more than 20 participating firms to provide institutional access, custody infrastructure and stablecoin liquidity.

The commitment figure represents capital pledged by Hashi’s launch coalition, rather than funds already deposited into the protocol. That distinction is important as mainnet deployment has not yet fully occurred. The rollout will happen in stages, allowing participating custodians, financial platforms and application providers to complete integrations before Bitcoin-backed products become broadly available.

Bitcoin Finance Connects Native BTC With Sui Applications
Hashi is designed to help people maintain their native Bitcoins in the Bitcoin network even when using them as collateral on financial applications running on top of Sui. Once Bitcoin gets deposited, Hashi mints hBTC on Sui, which gets pegged to the BTC that got deposited. The hBTC can be used in various financial applications that are built on Sui.
Once the user exits the platform, the respective hBTC gets burned, and the underlying Bitcoin becomes available in a Bitcoin address. This mechanism helps to separate Bitcoin custody from the financial activities on Sui. Additionally, Hashi allows third parties to build products based on Bitcoin Finance collateral without having to rely on the underlying asset being directly on Sui.
The development of Hashi has been going on for months now. The creator of Sui Mysten Labs launched the testnet of its protocol on July 22. According to TokenPost, on October 7, the Guardian Layer 2-of-2 multisignature involving Hashi validators and a guardian was introduced to the testnet, and over 20 institutional partners have already joined the project as of September 2.
Bitcoin Finance Network Builds Diverse Infrastructure
However, the investment of over $500 million provides Hashi with a sizeable amount of committed capital ahead of mainnet. However, one should consider that the announced figure does not represent the actual total value locked at the moment. It is uncertain what portion of the liquidity in Bitcoin or stablecoins has already been committed to live Hashi contracts.
When users exit the system, the corresponding hBTC is burned and the underlying Bitcoin is released back to a Bitcoin address. Deposits, hBTC circulation, lending and liquidity of stablecoins will provide a better understanding of Hashi’s usage after the mainnet goes online. Initial investments indicate an intent to participate, while actual on-chain metrics will provide a measure of capital utilization in Hashi’s ecosystem.
The consortium of launch partners features BitGo, Bullish, Cumberland, FalconX, and Ledger, as well as over 20 additional participants. Additionally, Sui identified Aftermath, Concrete, and Fluid as Hashi vault operators. Partners include custodians, liquidity providers, lenders, wallet services, and infrastructure companies, ensuring Hashi the necessary channels for utilizing Bitcoin for financial products.
Anchorage Adds Institutional Access
For its entry into Hashi, Anchorage Digital will employ the institutional avenue via the services of Atlas, which provides its settlement and tri-party collateral infrastructure, and Porto, an institutional self-custody wallet service. Anchorage will also offer liquidity in the stablecoin segment.
Anchorage CEO Nathan McCauley said institutions and public companies hold large amounts of Bitcoin but have faced limitations when attempting to use those holdings within decentralized finance. The approach by Anchorage will revolve around linking institutional holdings of Bitcoin with financing options without necessarily compromising the custodial and operational elements.
The institution angle can prove to be key because Bitcoin holders are forced to choose between having exposure to the BTC and being able to access liquidity. Unlike other solutions, Hashi enables one to borrow against Bitcoin finance without having to liquidate the underlying asset. Applications of Hashi include lending, credit markets, vaults and structured products.
Bitcoin Finance Security Strengthens Through Hashi’s Guardian Layer
Hashi employs MPC security, Sui smart contracts, and Guardian Layer for handling the movement of Bitcoin collateral. This collateral system implements a 2-of-2 multisignature scheme where two approvals are needed from Hashi validators and the guardian. The new control layer is implemented as an extra measure before the Bitcoin collateral exits the network.
As more funds enter the protocol, security will continue to be an important issue. According to Sui, the Hashi smart contracts have been verified formally by Certora, while CommonPrefix examined its cryptography in relation to its MPC protocol. However, these verification processes do not eliminate any smart contract, custody, or operation risks in the protocol.
Mainnet Rollout Will Start This Month
October is set as the release date for the phases of the mainnet by Hashi, and access is likely to increase as participating companies get their integrations done. The initial phase will help decide the amount of capital that is put into use, and also determine the amount of BTC that comes into the system, and how soon hBTC adoption increases within Sui platforms.
The key takeaway for the market is that Hashi is moving Bitcoin-backed finance from testing toward live deployment on Sui, while its announced $500 million represents commitments rather than confirmed deposits. The next milestones will be actual mainnet activation, BTC deposits, hBTC issuance, application launches and measurable liquidity.
