Institutional market maker Cumberland, asset management platform SwissBorg, and decentralized lending and DEX protocol Fluid have joined Hashi, the Bitcoin financial platform on the Sui ecosystem. Hashi, which has already secured support from over 20 institutions including BitGo and Ledger, aims to unlock over $1 trillion in dormant Bitcoin for DeFi applications. The platform plans to launch its global testnet in July, allowing partners to test integration and verify cryptographic integrity before the mainnet launch.
