#How Does Bitcoin Fit into the DeFi Ecosystem?
Bitcoin is often referred to as the most significant asset in the world of decentralized finance, or DeFi. Despite its substantial value, much of Bitcoin remains idle, as most DeFi activities occur on platforms like Ethereum. The recent introduction of Hashi, a Bitcoin collateralization protocol on Sui, aims to change this status quo. The protocol is currently in its testnet phase, available at devnet.hashi.sui.io.
#What is the Function of Hashi?
Hashi simplifies the process of utilizing Bitcoin as collateral. Users can deposit their native Bitcoin and receive hBTC, a token on the Sui blockchain. This token can then be employed for institutional lending or stablecoin borrowing, all while ensuring the original Bitcoin stays secure on its blockchain.

#How Does the Guardian Layer Enhance Security?
The protocol integrates advanced security measures involving multi-party computation (MPC) threshold signatures. These signatures require the consensus of at least one-third of validators to minimize risks associated with collusion. An additional feature, known as the Guardian Layer, acts as a protective measure, verifying large withdrawal requests against pre-established thresholds. This essentially creates a safeguard that must be met before any significant amount of Bitcoin exits the system.
#What is the User Experience Like?
When using Hashi, the user initiates the process by depositing Bitcoin. After confirmation by Sui validators, hBTC is minted for smart contract use, with the actual Bitcoin remaining untouched on its native chain. Leveraging move programming language, Hashi enforces stringent asset ownership rules to ensure secure transactions.
#Who is Supporting Hashi?
Hashi has garnered investment from prominent industry names such as SwissBorg, Cumberland, Fluid, BitGo, and Ledger. These partnerships highlight the protocol's credibility and potential within the crypto ecosystem. The primary applications of Hashi include institutional lending against Bitcoin collateral and issuing stablecoins that are backed by verifiable Bitcoin positions.
#What Should Investors Anticipate for July 2026?
Currently, the Hashi testnet operates in a development phase, while a widespread rollout is planned for July 2026. The revenue model is designed around interest spreads. Institutions borrowing using Bitcoin as collateral generate yield through the difference between deposit and borrowing rates. This model is sustainable, independent of token inflation or market speculation.
#Key Considerations for the Future
Investors should closely monitor the performance of the devnet under various conditions and watch for commitments from institutional backers regarding the mainnet launch. The capability of the Guardian Layer to withstand challenges during testing will serve as a critical indicator of success leading into the broader rollout set for July 2026.
