Bitcoin-backed finance (BTC, $82,538.32) is set to receive a substantial, well-capitalized liquidity injection.

Sui, the layer-1 blockchain, is preparing to launch Hashi, a new institutional network that enables holders to use Bitcoin as collateral for lending without moving the asset off the Bitcoin ledger. The mainnet is scheduled to roll out in phases later this month.

To back the ecosystem, the initiative has already secured $500 million in capital commitments from a coalition of more than 20 industry partners. While these are commitments rather than immediate deposits, the pre-pledged capital is intended to ensure that when the system debuts, markets can open with deep liquidity instead of starting empty. As the phased rollout begins, the pace at which those pledges convert into deployed, on-platform liquidity will be one of the earliest observable indicators of how the network's new markets take shape.

"Hashi is launching with serious capital and a coalition of industry leaders because institutions want to put Bitcoin to work without giving up the protections they require," said Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs, the original creator of Sui, in an official announcement.

The primary target for this capital is a vast pool of dormant wealth. Sui estimates that roughly $1 trillion worth of Bitcoin is currently sitting idle. Until now, institutional and corporate balance-sheet holders have lacked a compliant, transparent ecosystem through which to safely deploy their native Bitcoin in decentralized finance (DeFi). The constraint is partly structural: Bitcoin's base ledger does not natively support the smart contracts that power DeFi, so BTC used in such applications has historically had to be represented through wrapped or bridged tokens issued on other chains — a step Hashi's on-ledger design is built to remove.

The launch arrives amid a broader shift in Bitcoin-backed finance, in which borrowing is moving far beyond speculative crypto trading. Holders increasingly use bitcoin-collateralized loans to cover real-world expenses such as university tuition, real estate acquisitions, and corporate working capital.

"Public companies and institutions hold enormous amounts of Bitcoin, but their ability to use that capital has been constrained by the technology available to them," said Nathan McCauley, CEO and co-founder of Anchorage Digital, an institutional digital-asset platform and a day-one launch partner that also plans to supply stablecoin liquidity to the network — liquidity that would form the lending side of Hashi's bitcoin-collateralized loan markets. "Connecting our institutional clients with Hashi represents a complete paradigm shift," McCauley added.

How the Architecture Addresses Institutional Constraints

Instead of bridging across blockchains, users securely lock their BTC in a vault address directly on the Bitcoin blockchain. A 2-of-2 multisig secures this address, requiring cryptographic sign-off from both of Hashi's validators. The distinction is notable: bridge-based models require assets to be held by contracts on a destination chain — an architecture that has historically ranked among crypto's most frequently exploited — whereas collateral here remains on the Bitcoin ledger for the life of the loan.

Hashi also maintains a separate, independent guardian layer designed to monitor and slow suspicious collateral movements.
