TL;DR:
Sui, the layer-1 blockchain, launched Hashi, a platform designed to integrate Bitcoin liquidity into the decentralized finance ecosystem. The goal is to transform an asset that largely remains static into a productive instrument, without requiring holders to sell their positions.
Only a minimal fraction of circulating Bitcoin actively participates in the DeFi ecosystem. Hashi seeks to reverse that proportion by offering mechanisms for lending, borrowing and yield generation managed through smart contracts.

What sets SUI’s product apart from similar previous attempts is the quality of the players involved. BitGo, Bullish, FalconX and Ledger form the core of the institutional backing, covering the areas of custody, liquidity and infrastructure, which are exactly the variables that determine whether a traditional financial institution decides to commit real capital to a protocol.
Joining that group are firms specialized in data, security and transparency, along with CF Benchmarks and Cubist for price and asset flow management, and auditing group Certora for system verification. It is an architecture that deliberately aims to reduce the limitations that have historically kept institutional capital away from the DeFi market.

Rather than relying on wrapped assets, a mechanism that has historically carried complexity and risk issues, SUI uses smart contracts to track Bitcoin across chains. The system links Bitcoin addresses directly to onchain activity, giving users real visibility into collateral, loans and ongoing transactions.
For risk management, the platform incorporates an insurance layer through Soter Insure, which features Bitcoin-denominated policies. Both premiums and claims are settled in BTC, eliminating any mismatch against external assets.
SUI’s roadmap contemplates expansion into structured products, automated vaults and Bitcoin-backed bonds. Firms such as Wave Digital are already exploring how to use the system for BTC-tied capital raising operations. If adoption matches the infrastructure, Hashi could gradually but steadily redefine Bitcoin’s role within decentralized finance.
