The Sui Foundation launched Hashi, a new protocol on March 19, 2026, that allows Bitcoin holders to borrow against their BTC holdings without selling—potentially unlocking billions in stagnant crypto capital for decentralized finance.
The protocol, backed by institutional players BitGo, Ledger, and Bullish, is launching on Sui’s devnet with plans to move to mainnet, where it will enable collateralized lending, yield generation, and tokenized financial products backed by Bitcoin collateral.
At its core, the Hashi protocol introduces a mechanism for Bitcoin holders to access liquidity without parting with their assets. Traditionally, BTC holders seeking liquidity must sell their coins, triggering tax events and forfeiting long-term exposure.
The Hashi protocol changes that equation by enabling collateralized lending, where users can borrow against Bitcoin holdings while maintaining ownership. This approach mirrors traditional finance structures but adapts them for decentralized systems.
“Think of Hashi as the unlock for developers to design solutions opening access to trillions in BTC liquidity,” said Adeniyi Abiodun, highlighting the broader ambition behind the Hashi protocol.
The Hashi protocol relies on advanced cryptographic infrastructure to ensure both security and compliance. It uses multi-party computation (MPC), a method that distributes key control across multiple parties, reducing single points of failure and enhancing asset protection.
In addition, the Hashi protocol incorporates the ERC-3643 token standard, which is specifically designed for permissioned and compliant digital assets. This allows institutions to participate while adhering to regulatory requirements a key factor in bridging traditional finance with crypto.
To further strengthen trust, the Hashi protocol includes insurance coverage provided by Soter and formal verification conducted by Certora. These safeguards aim to ensure that collateral remains secure and that smart contracts behave exactly as intended.
Beyond basic lending, the Hashi protocol is positioning itself as a foundation for more sophisticated financial instruments. Following its devnet phase, the protocol is expected to move to mainnet, where partners like Wave Digital plan to issue structured financial products backed by Bitcoin.
Among these are secured and rated bonds collateralized by BTC, a development that could attract institutional capital seeking predictable returns. The Hashi protocol is designed to support such instruments while maintaining transparency and onchain verification.
This evolution marks a significant step toward integrating Bitcoin into global capital markets, moving it beyond its traditional role as a store of value.
The Hashi protocol will also integrate with native Sui ecosystem platforms, including Navi Protocol and Scallop. These integrations will allow users to access BTC-backed stablecoin loans almost immediately after launch.
For retail users, this means faster access to liquidity and new opportunities to earn yield. For developers, the Hashi protocol provides a toolkit for building applications that leverage Bitcoin in ways previously not possible.
By connecting Bitcoin to DeFi ecosystems, the Hashi protocol is effectively expanding the utility of the world’s largest cryptocurrency.
Despite its promise, the Hashi protocol enters a competitive and evolving landscape. Several projects have attempted to bring Bitcoin into decentralized finance, often facing challenges related to security, liquidity fragmentation, and regulatory uncertainty.
The Hashi protocol seeks to address these issues through its compliance-first design and institutional partnerships. However, its success will depend on adoption, particularly among large capital holders who can drive meaningful liquidity into the system.
Regulatory scrutiny is another factor to watch. As governments increase oversight of crypto lending and tokenized assets, the Hashi protocol’s compliance features may prove to be both a strength and a necessity.
The launch of the Hashi protocol reflects a broader shift in how Bitcoin is being used within the crypto economy. No longer confined to passive holding, BTC is increasingly being integrated into financial systems that generate yield and unlock liquidity.
If successful, the Hashi protocol could redefine Bitcoin’s role, transforming it from a static asset into a dynamic component of decentralized finance.
For now, the devnet launch marks the first step in what could become a major evolution in crypto infrastructure one where the Hashi protocol plays a central role in unlocking the full financial potential of Bitcoin.
