Sui announces Hashi for BTC DeFi infrastructure

Sui has introduced Hashi, a Bitcoin-focused infrastructure layer designed to let native BTC function as collateral inside the network’s decentralized finance ecosystem. The project is being positioned as a way to unlock Bitcoin-backed lending and credit markets without relying on wrapped tokens or conventional cross-chain bridges.

The infrastructure aims to keep Bitcoin settlement anchored to its native chain while making collateral utility available on Sui. A global testnet is approaching, but Hashi is not yet live as a mainnet lending venue.

Hashi Targets Wrapped-BTC-Free Lending

Hashi’s core pitch is using native Bitcoin as collateral without converting it into a wrapped asset. That distinction matters for institutions and large holders that remain cautious about bridge risk, custodian assumptions and synthetic BTC representations.

Project materials describe the system as using multi-party computation and regulated pricing layers to maintain verifiable control over deposited Bitcoin. The goal is to create collateral workflows that preserve Bitcoin custody assurances while enabling borrowing and credit activity on Sui.

The structure also targets the large pool of idle BTC sitting outside DeFi markets. If Hashi can provide credible collateral access without wrapping or bridging, it could give Bitcoin holders a more direct path into lending and liquidity strategies.

Testnet Will Define the Practical Scope

A coalition of infrastructure and market participants has aligned around Hashi’s planned testnet phase, with reported backers including BitGo, FalconX, Ledger, Cumberland, SwissBorg and Fluid. Their interest reflects demand for Bitcoin collateral infrastructure with fewer bridge-related assumptions.

The project’s institutional framing remains dependent on testnet validation. Hashi still needs to show how custody controls, pricing, liquidation logic and user access work under realistic market conditions.

Key lending parameters remain not yet published, including supported markets, collateral ratios, liquidation thresholds, interest-rate models and participation requirements. Those details will determine whether Hashi becomes a practical credit primitive or remains an infrastructure concept.

Hashi gives Sui a clear strategy for bringing native Bitcoin into DeFi collateral markets. The next useful indicators will be testnet access, technical documentation, liquidation design, partner participation, security review and whether the system can move toward mainnet without introducing the same trust risks it aims to avoid.
