Sui's Hashi Bitcoin collateral network will launch with more than $500 million in committed liquidity from over 20 partner organizations, the Sui Foundation announced on October 8, 2026 at the project's Basecamp conference.

The capital is described by the foundation as committed funding intended as initial liquidity for launch, not deposits already parked inside the protocol. Anchorage Digital stands out as the most prominent institutional partner.

The digital asset infrastructure firm will route clients to Hashi through two products: the Atlas tri-party collateral settlement system, which operates within qualified custody, and the Porto self-custody wallet. Anchorage is also contributing stablecoin liquidity to support early market activity.

What is Hashi and how does it work?

Hashi keeps native BTC on the Bitcoin network itself. Smart contracts running on Sui coordinate how that collateral is deployed across lending, borrowing, credit, vaults, and structured products.

The protocol mints hBTC, a tokenized representation of Bitcoin on Sui. Holders can move between hBTC and native BTC through built-in deposit and withdrawal mechanisms tied to the threshold-signature scheme.

Security rests on threshold cryptography, commonly called multi-party computation (MPC). Each Sui address adopts a 2-of-2 multisig arrangement, meaning two distinct keys must sign before any movement is finalized.

A guardian rate-limiter sits on top of that cryptographic stack. Its job is to cap the velocity of fund flows, so a bad actor cannot drain the system in a single attempt.

The foundation frames the design as a direct response to two complaints Bitcoin purists raise about most bridging solutions: trust-dependent wrapping and centralized custody of the underlying reserve.

Why does Anchorage Digital matter?

Anchorage's participation through a qualified-custody settlement system gives regulated players a familiar compliance framework, the foundation argued. Banks, registered investment advisers, and corporate treasurers typically already understand tri-party collateral workflows from traditional finance.

Beyond Anchorage, capital is expected to flow into early applications through vault providers including Aftermath, Concrete, and Fluid. These protocols typically run automated lending and yield strategies against deposited collateral.

How did Hashi get to mainnet?

Hashi's testnet went live on July 22, 2026. The 78-day interval between testnet deployment and the Basecamp announcement produced a phased mainnet timeline.

The Sui Foundation confirmed that the phased rollout is expected to begin later in October 2026, without specifying individual phase dates.

What should institutions track next?

Three data points will determine whether Hashi converts headline commitments into recurring operational use:

• Conversion of the $500 million-plus in commitments into live on-chain liquidity
• hBTC adoption metrics across Aftermath, Concrete, and Fluid
• Bitcoin volume routed by Anchorage clients through Atlas or Porto

The rate-limiter design presents a trade-off worth monitoring. It slows attackers, but it also constrains legitimate withdrawals during periods of market stress, the precise moment when holders demand quickest access to their coins.
