Sui is preparing to launch Hashi, an institutional network designed to enable Bitcoin-backed lending while keeping BTC on the Bitcoin blockchain. The mainnet rollout is scheduled to begin in phases later this month, with the initiative securing $500 million in capital commitments from a coalition of more than 20 industry partners ahead of launch.
The commitments are intended to provide an initial foundation for liquidity as the network becomes operational. However, pledged capital does not necessarily represent funds already deposited or immediately available for lending. The distinction will be important in assessing how much liquidity Hashi can attract and deploy once its markets open.
Developed within the Sui ecosystem, Hashi targets institutional and corporate Bitcoin holders seeking to generate returns from their assets without transferring BTC to another blockchain. Sui estimates that approximately $1 trillion worth of Bitcoin remains idle, representing a potentially substantial source of collateral for lending and decentralized finance. Unlocking that capital, however, depends on institutions having access to infrastructure that meets their requirements for security, transparency and operational oversight.
The initiative reflects a broader expansion of Bitcoin-backed finance beyond speculative trading. Bitcoin-collateralized borrowing is increasingly being considered for practical funding needs, including real estate purchases, education expenses and corporate working capital. For companies holding Bitcoin on their balance sheets, the ability to borrow against those assets could provide access to liquidity without requiring an outright sale of their holdings.
Anchorage Digital is among Hashi’s launch partners and plans to provide stablecoin liquidity to the network. Its participation highlights the importance of connecting institutional custody and financial services with decentralized lending infrastructure. The project’s ability to attract further institutional participants will depend partly on whether its security arrangements and lending mechanisms satisfy the operational requirements of larger capital providers.
Hashi’s architecture is designed to avoid conventional cross-chain bridging. Users lock their BTC in a vault address directly on the Bitcoin blockchain, with a 2-of-2 multisignature arrangement requiring cryptographic authorization from both Hashi validators. A separate guardian layer is designed to monitor collateral movements and slow suspicious activity, adding another layer of oversight.
Although these mechanisms are intended to address institutional security concerns, their effectiveness will depend on implementation, validator coordination and the procedures governing access to collateral. The structure also makes the network’s operational safeguards and recovery processes important considerations for prospective participants.
The initial $500 million in commitments gives Hashi a substantial starting point, but it does not by itself establish the amount of lending activity the network will ultimately support. Adoption will depend on how much committed capital becomes available, the demand for Bitcoin-backed borrowing, the terms offered to borrowers and lenders, and institutional confidence in the network’s security model.
The phased mainnet rollout will therefore be an important test of whether Bitcoin holders can access decentralized credit while retaining their assets on Bitcoin’s native ledger. If Hashi converts its commitments into active liquidity and attracts sustained institutional demand, it could help expand the role of Bitcoin as collateral in digital-asset finance.
