Grand Cayman, Cayman Islands, June 23rd, 2026, ChainwireSui aims to transition more of Bitcoin’s $1.2T market cap into verifiable, productive onchain products.Hashi, Sui’s native bitcoin finance primitive, gains more institutional support ahead of the scheduled launch of its global testnet this July. Sui, where money moves as freely as messages, announced today that Cumberland, Fluid, and SwissBorg have joined the Hashi ecosystem, Sui’s native bitcoin finance primitive, weeks ahead of its scheduled global testnet launch this July. The expanding coalition addresses a critical bottleneck in crypto: solving the persistent capital inefficiency by unlocking over a trillion dollars of immobile BTC into DeFi safely. Previous market cycles demonstrated the systemic dangers of relying on opaque, centralized credit intermediaries such as Celsius, Voyager, and Genesis to generate utility from dormant assets. Hashi replaces centralized balance-sheet trust with verifiable smart contract logic.But with a strict separation for safety by design, Bitcoin remains securely on the native Bitcoin blockchain. Sui smart contracts handle the cryptographic and programmatic rights to enable its use as financial collateral.“Hashi was built to unlock the productive use of Bitcoin at a scale the industry hasn't seen before,” Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs, the original contributor to Sui. “We believe Bitcoin will become one of the largest sources of collateral in finance as the world moves onchain, and Hashi provides the foundation to make that possible on Sui.”Built for Institutional Bitcoin FinanceHashi is a foundational primitive setting a new standard for how builders can create bespoke, Bitcoin-backed financial products with risk parameters and loan terms that are fully verifiable onchain. In just a few weeks’ time, institutions, custodians, wallet providers, and developers can begin freely testing the infrastructure that will support Bitcoin-backed lending, borrowing, and credit origination on Sui.
