Hashi Announces Institutional Partnerships Ahead of July 2026 Sui Testnet
The strategy is to create a non‑custodial, high‑throughput gateway that lets Bitcoin holders use their native BTC as collateral in Sui’s decentralized finance (DeFi) ecosystem. By keeping the physical Bitcoin in cold storage on the Bitcoin blockchain and managing only the cryptographic rights on Sui, Hashi seeks to eliminate the trade‑off that has historically forced users to surrender ownership of their BTC to centralized custodians.
Hashi’s architecture relies on a dual‑layered cryptographic design. The first layer retains the actual BTC in secure, off‑chain custody. The second layer, written in the Move programming language, controls the state transitions that enable borrowing, lending, and liquidation on Sui. Formal mathematical verification is applied to the Move contracts to guarantee that the logic behaves exactly as specified, reducing the risk of bugs or exploits.
The three new partners bring complementary capabilities to the protocol.
* Cumberland is the crypto‑assets arm of DRW Holdings, a global proprietary trading firm. Cumberland’s market‑making expertise is expected to provide deep liquidity and order‑book depth, allowing large institutional positions to be executed with minimal slippage.
* SwissBorg is a European digital wealth‑management platform with more than one million retail and high‑net‑worth users. SwissBorg’s involvement is aimed at creating compliant access pathways that let its client base borrow against idle BTC through Hashi’s institutional portal.
* Fluid is a decentralized lending protocol known for its capital efficiency. Fluid’s integration will enable real‑time, algorithmic management of interest rates, liquidation curves, and treasury pools, aligning the protocol’s risk profile with the expectations of conservative asset managers.
Hashi’s earlier collaborations with BitGo, FalconX, and Bullish have already established a foundation of regulated custody, prime brokerage, and exchange services. The new trio expands that foundation into the realms of market making, wealth management, and lending.
The July 2026 testnet is described as a “simulation runway” that will allow institutional engineers, database managers, and cryptographic auditors to stress‑test the protocol under conditions of high volatility and load. The testnet will validate transaction throughput, latency, and the integrity of the liquidation engine before the mainnet launch.
Industry observers see the partnership as a response to the failures of centralized lenders such as Celsius, BlockFi, and Voyager. Those collapses highlighted the risk of opaque balance sheets and leveraged positions that were not backed by transparent collateral. Hashi’s design, by contrast, keeps the BTC on the Bitcoin chain and uses on‑chain, mathematically verified contracts to manage collateral, thereby removing counterparty risk.
The collaboration also signals growing confidence among institutional players that a high‑performance smart‑contract platform can accommodate the scale and regulatory requirements of large‑value Bitcoin holders. By providing a bridge that preserves ownership while enabling productive use of capital, Hashi may help unlock idle BTC that has been held in cold storage for years.
The protocol’s developers have stated that the testnet will be the final step before a production‑ready mainnet. Successful completion of the testnet would pave the way for Bitcoin to circulate as collateral in Sui’s DeFi markets, potentially reshaping how institutional capital interacts with the broader cryptocurrency ecosystem.
As of the latest public statements, the Hashi team has not announced a specific mainnet launch date. The focus remains on ensuring that the testnet meets performance and security benchmarks set by the protocol’s partners.
In summary, Hashi’s integration of Cumberland, SwissBorg, and Fluid ahead of its July 2026 testnet represents a coordinated effort to bring institutional Bitcoin capital into a non‑custodial, mathematically verified DeFi environment on Sui. The partnership aims to provide liquidity, compliance, and efficient lending, while the upcoming testnet will validate the protocol’s readiness for a broader market rollout.
