> Sui Foundation rolls out Hashi mainnet with Anchorage Digital custody, unlocking $500M in institutional Bitcoin collateral for Move-based decentralized finance.

## TL;DR
- The Sui Foundation launched the phased mainnet deployment of Hashi on October 18, 2026.
- The protocol unlocks institutional Bitcoin liquidity for Move-based decentralized finance protocols.
- More than $500 million in initial capital commitments were secured across twenty institutional partners.
- Qualified custody is managed by federally chartered Anchorage Digital, issuing 1:1 backed hBTC tokens on Sui.

## Key points
- Hashi eliminates multi-sig cross-chain bridge vulnerabilities by utilizing regulated, qualified custodial reserves.
- The hBTC token operates natively on Sui, taking advantage of sub-second finality and object-centric smart contracts.
- Decentralized money markets and automated market makers can integrate hBTC as primary collateral with zero wrapping delay.
- Over twenty institutional liquidity providers committed capital to support deep market depth from day one.
- The rollout marks a strategic expansion of native Bitcoin utility across alternative Layer-1 execution environments.

## What happened

On October 18, 2026, the Sui Foundation officially commenced the phased mainnet deployment of Hashi, an institutional-grade cross-chain liquidity and collateral framework designed to integrate Bitcoin directly into Move-based decentralized finance ecosystems. Developed in collaboration with Mysten Labs and federally chartered digital asset bank Anchorage Digital, the protocol enables institutional Bitcoin holders to deploy their assets into on-chain lending, borrowing, and automated market making with sub-second settlement finality.

Historically, bridging Bitcoin to smart-contract platforms required users to lock capital in centralized wrapped-token contracts or vulnerable multi-signature bridge arrangements. These historical designs generated multi-billion-dollar security exploits and failed to meet the rigorous custody standards demanded by institutional asset managers.

Hashi resolves these vulnerabilities by pairing Anchorage Digital's qualified institutional custody with Sui's object-centric Move runtime. When institutions deposit Bitcoin, reserves are held in segregated, bankruptcy-remote vaults under federal regulatory oversight, while cryptographic proofs automatically mint one-to-one backed hBTC tokens on Sui. Backed by over $500 million in initial liquidity commitments from a coalition of twenty trading firms and decentralized market makers, Hashi establishes immediate depth across core Move liquidity pools.

## Why it matters

Bitcoin remains the preeminent digital asset by market capitalization, yet more than ninety-five percent of circulating BTC supply sits idle in cold storage vaults, disconnected from productive decentralized yield and capital efficiency. For asset allocators holding substantial Bitcoin treasuries, generating low-risk on-chain yield without forfeiting custody assurances has been a persistent industry goal.

By establishing an institutional bridge backed by qualified custody, Hashi unlocks billions of dollars in dormant capital for decentralized credit markets. Decentralized exchanges and lending protocols operating on Sui can now accept native-grade Bitcoin collateral without exposing liquidity providers to wrapped token de-pegging risks or opaque cross-chain bridge governance.

Furthermore, Sui's parallel transaction execution and sub-second transaction finality provide a uniquely performant environment for institutional trading. Unlike congested proof-of-work or serial execution architectures, high-frequency liquidity rebalancing and algorithmic liquidations execute deterministically without causing network spikes or catastrophic collateral liquidations during market volatility.

## Technical details

The technological architecture of Hashi centers around a verifiable multi-party computation (MPC) attestation network coupled with Move smart contract object constraints. Physical Bitcoin custody is orchestrated through Anchorage Digital's segregated institutional vaults, utilizing hardware security modules and multi-signatory threshold signing.

When a deposit transaction confirms on the underlying Bitcoin blockchain, Anchorage's attestation layer emits an audited cryptographic receipt. Sui's native Move consensus ingests this receipt through dedicated consensus-level oracle modules, which programmatically mint the corresponding quantity of hBTC directly into the depositor's designated Sui address.

In the reverse redemption direction, burning hBTC on Sui triggers an immutable on-chain burn receipt. Anchorage's automated withdrawal gateway verifies the cryptographic burn event before initiating an on-chain transfer on the Bitcoin network directly to the user's whitelisted institutional wallet. All collateral reserves are continuously verified by real-time proof-of-reserve oracles that publish cryptographically signed balance sheets to the public ledger every three minutes.

## Market / industry impact

The launch of Hashi marks an important step in the institutional maturation of decentralized finance, demonstrating that regulated compliance infrastructure and decentralized execution layers can merge seamlessly.

For the Sui ecosystem, securing over $500 million in day-one Bitcoin liquidity commitments accelerates total value locked (TVL) growth and establishes a competitive differentiator against rival high-performance Layer-1 networks. As decentralized money markets on Sui incorporate hBTC as pristine collateral, trading volumes across lending protocols such as Scallop and Navi Protocol are projected to expand significantly.

More broadly, the initiative intensifies competition among alternative smart contract platforms vying for Bitcoin liquidity. With major institutional allocators increasingly seeking yield in regulated environments, protocols that offer verifiable custody, sovereign asset segregation, and rapid execution speeds are capturing market share from legacy bridge platforms.

## What to watch next

Market participants will closely monitor collateral utilization rates across primary Sui money markets over the initial thirty-day deployment window, observing whether deposit yields remain attractive as institutional liquidity ramps up.

Analysts will also track the activation of secondary structured financial products, such as delta-neutral basis trading vaults and automated liquidity management vaults built natively on top of hBTC.

Finally, the cryptocurrency industry will observe whether traditional asset managers expand their use of Hashi beyond pure decentralized lending into tokenized sovereign debt and real-world asset collateralization protocols.
