Sui2026-09-15 19:19:31Sui says $1.5 trillion in Bitcoin is idle as Hashi mainnet nears launchSui said in a post on X that more than $1.5 trillion worth of Bitcoin is sitting idle, arguing that using BTC often means handing it over to someone else. The project said Hashi is designed to change that setup by keeping Bitcoin on the Bitcoin network while opening access to financial services on Sui. Sui added that the Hashi mainnet is set to go live soon. The statement frames Hashi as an upcoming bridge between Bitcoin’s base network and Sui-based financial use cases, without requiring BTC to leave the Bitcoin network, according to the company’s post.670
Sui2026-08-22 14:04:48Sui says Hashi mainnet is near after testnet deposits top 2 millionSui said in a post on X that Bitcoin has returned to timelines across the internet, though much of it still sits idle in cold wallets. The project said Hashi is designed to make native Bitcoin usable as programmable collateral on Sui while remaining on the Bitcoin network. Sui also disclosed that Hashi’s testnet has recorded more than 2 million deposits. With that milestone reached, the team said the protocol’s mainnet launch is coming soon. The update focuses on Bitcoin utility on Sui and frames Hashi as infrastructure meant to keep BTC on its original network while extending its use in programmable onchain applications.1400
Sui2026-08-18 09:36:09Sui’s Hashi testnet processed more than 1.1 million Bitcoin deposits in three weeksSui’s Hashi Bitcoin lending protocol has processed more than 1.1 million Bitcoin deposits and 165,000 withdrawals within three weeks of its testnet launch on July 22. As of last week, more than 25 institutions had joined stress testing for the system, according to Bitcoin.com News. Participants named in the report include digital asset custodian BitGo, trading firm Cumberland, as well as Swissborg, Fluid and Ledger, spanning trading, custody infrastructure and wealth management platforms. Hashi lets users deposit native Bitcoin and receive hBTC after Sui validators confirm the transaction, with the minted asset used for on-chain lending and stablecoin borrowing. For security, deposits use a 2-of-2 multisignature setup backed by MPC validator signatures, while withdrawals are subject to review through the Guardian Layer. The project plans to move toward a 2026 mainnet launch after that security layer completes its security review.1420
Hashi2026-08-10 18:59:49Hashi Testnet Panel Now Shows Real-Time Deposits and Withdrawals, Sui Thanks CommunitiesSui said in a post on X that the Hashi testnet dashboard now shows real-time deposit and withdrawal records. The project also thanked the Sui and Bitcoin communities for testing Hashi and helping drive improvements.1960
Hashi2026-08-10 18:59:51Hashi Testnet Processes Over 1.1M Deposits in Three Weeks; Bitcoin Signet Sees Half of Transactions From TestingChainCatcher reports that the Hashi testnet has processed over 1.1 million deposits and 165,000 withdrawals since going live three weeks ago, according to Sui monitoring. Over the past two weeks, more than 50% of Bitcoin Signet transactions came from Hashi testing activity.1990
Bitcoin2026-08-06 06:29:41Hashi’s 25-Plus Institution Stress Test Puts Focus on Where Bitcoin Programmability Should LiveHashi’s testnet on Sui has drawn participation from more than 25 institutions in a push to let Bitcoin take part in DeFi without leaving the Bitcoin network. The article argues that the market debate has shifted: the question is no longer whether BTC should be programmable, but where that programmability should sit. Hashi keeps the underlying BTC in 2-of-2 multisig Bitcoin addresses while execution happens on Sui, a setup the author says improves asset safety but still leaves users relying on two systems at once. Against that backdrop, TuringBitChain, or TBC, is presented as a different route. Rather than splitting assets and contract logic across chains, it says it writes Turing-complete smart contracts directly into the UTXO model at Layer 1. The piece contrasts the two approaches across trust assumptions, architecture, performance claims, developer trade-offs, and institutional readiness, framing the broader contest around whether programmable BTC finance will be built through external execution layers or within UTXO itself.2070
Bitcoin2026-07-30 12:36:31Hashi launches on Sui testnet to put idle Bitcoin capital to workHashi has gone live on Sui testnet in July, opening a live environment for developers, custodians, financial institutions and ecosystem partners to build, integrate and stress-test Bitcoin-backed financial applications before mainnet. The launch is framed around a striking imbalance in the Bitcoin economy: while BTC’s market capitalization stands at roughly $1.31 trillion, only about $4.3 billion is currently deployed in DeFi, according to DefiLlama, or less than 0.33% of the total. In other words, more than 99.6% of Bitcoin remains largely idle in wallets rather than being used in lending, collateralized finance or yield-bearing products. Hashi introduced its Guardian Layer alongside the testnet, adding an independent verification layer on top of its existing threshold-signature model. Under the design described in the article, BTC collateral sits behind a 2/2 multisig structure that requires both MPC signatures from Hashi validators and a Guardian signature before release. The project also said the testnet ecosystem includes more than 25 partners spanning custody, wallets, lending, liquidity, asset management, insurance, oracle services and smart contract auditing.2110
Sui2026-07-24 11:34:26Sui and Mysten Labs launch Hashi testnet for native Bitcoin-backed lendingSui Foundation and Mysten Labs said on July 22 that they have launched the testnet for Hashi, a Bitcoin collateral protocol designed to let BTC support on-chain lending and credit markets without being wrapped into synthetic tokens or moved through a cross-chain bridge. Under the setup described by the teams, Bitcoin remains on the Bitcoin network, while deposits are secured through a 2-of-2 multisignature structure that requires signatures from both Hashi MPC validators and an independent Guardian Layer. Loan terms and collateral positions are recorded on-chain so lenders can review the backing behind each position. More than 25 institutional partners are already testing Hashi’s lending and credit applications, including Bitgo, Cumberland, FalconX, Ledger, Blockdaemon, Bullish, and Sui ecosystem lending platforms Navi and Scallop. Wave Digital Assets has also committed to advancing a three-year tokenization plan for a Bitcoin yield bond on Sui after Hashi reaches mainnet. No mainnet launch date has been announced.1590
