Sui’s Hashi Testnet Goes Live, Targeting a Slice of Bitcoin’s $1.4 Trillion Market

A Bridge Built to Avoid Bridges

The Sui Foundation and Mysten Labs confirmed Hashi’s testnet went unrecorded connected July 22, the latest measurement successful a task designed to fto bitcoin relation arsenic collateral successful onchain lending and recognition markets without wrapping it into a synthetic token oregon bridging it to different concatenation (the 2 approaches that person repeatedly caused losses crossed DeFi).

Sui archetypal announced Hashi astatine the devnet signifier backmost successful March, positioning the protocol arsenic a mode to unlock superior ratio crossed bitcoin’s astir $1.4 trillion market.

“Bitcoin is nary different” from different large assets erstwhile it comes to gathering recognition markets astir it, Mysten Labs Co-Founder and Chief Product Officer Adeniyi Abiodun said, adding that Hashi provides “the infrastructure to physique those markets onchain with the security, transparency, and programmability institutions person been waiting for.”

How Hashi Actually Works

Hashi keeps bitcoin connected the Bitcoin web itself alternatively than moving oregon re-minting it elsewhere. Deposits are secured done a 2-of-2 multisig statement requiring signatures from some Hashi’s multi-party computation (MPC) validators and a abstracted Guardian Layer, a configurable risk-management strategy designed to dilatory oregon artifact suspicious withdrawals earlier collateral tin permission the system.

Loan presumption and collateral positions are past tracked onchain, giving lenders afloat visibility alternatively of relying connected an intermediary’s connection for however overmuch bitcoin really backs a fixed loan.

The operation besides carries a taxation vantage implicit rival designs. Deposits and redemptions are structured, according to ineligible investigation cited by Sui, to debar triggering taxable events nether U.S. taxation law, a meaningful item for institutions weighing whether to enactment bitcoin to enactment alternatively than fto it beryllium idle.

Why the Wrapped-BTC Risk Is Real

The hazard Hashi is built to sidestep isn’t hypothetical, and Sui’s ain ecosystem has already lived done it. Volo Protocol, a liquid staking and bitcoin-finance level besides built connected Sui, mislaid $3.5 cardinal successful an April 2026 exploit aft an attacker compromised a vault admin’s backstage key, draining astir $2.1 cardinal successful wrapped bitcoin (WBTC) from 3 vaults. That’s the nonstop nonaccomplishment mode (i.e. a azygous custodial cardinal controlling wrapped collateral) that Hashi’s multisig-plus-Guardian-Layer plan is meant to marque acold harder to propulsion off.

Sui has taken different paths to bitcoin liquidity too. Threshold’s tBTC went unrecorded connected Sui arsenic a decentralized, non-custodial wrapped bitcoin alternative, and the Sui Bridge separately launched connected mainnet to determination assets similar ether betwixt Ethereum and Sui. Hashi is simply a antithetic stake wherever alternatively than wrapping oregon bridging bitcoin astatine all, it leaves the plus connected Bitcoin’s ain concatenation and settles everything other astir it.

Who’s Already Testing It

More than 25 organization partners are already stress-testing lending and recognition applications connected the testnet, including custody elephantine Bitgo, trading firms Cumberland and FalconX, hardware wallet shaper Ledger, infrastructure supplier Blockdaemon, speech Bullish, and Sui-native lending platforms Navi and Scallop.

Wave Digital Assets has besides committed to a three-year program prioritizing bitcoin-yield-bearing enslaved tokenization connected Sui erstwhile Hashi reaches mainnet, 1 of the clearest signs yet that accepted concern players spot the protocol arsenic much than a DeFi experiment.

That said, Hashi has nary announced mainnet day yet, and the testnet signifier exists specifically truthful builders and institutions tin integrate lending, borrowing, and recognition products earlier existent wealth is astatine stake. If the aviator holds up, Hashi would springiness bitcoin holders a mode to gain output connected autochthonal BTC without the custodial single-point-of-failure hazard that deed Volo Protocol conscionable 3 months ago.
