[Bitcoin Collateral Protocol Hashi Testnet Goes Live in $1.4 Trillion Market, Over 25 Institutions Participate in Testing] Odaily Planet Daily News – On July 22, Sui Foundation and Mysten Labs launched the testnet for the Bitcoin collateral protocol Hashi, enabling BTC to provide collateral support for on-chain lending and credit markets without being wrapped into synthetic tokens or bridged across chains. Hashi keeps Bitcoin on the Bitcoin network, with deposits secured through a 2-of-2 multi-signature mechanism requiring simultaneous signatures from Hashi multiparty computation validators and the independent Guardian Layer. Loan terms and collateral positions are recorded on-chain, allowing lenders to review collateral support details. More than 25 institutional partners are testing Hashi's lending and credit applications, including Bitgo, Cumberland, FalconX, Ledger, Blockdaemon, Bullish, as well as Sui ecosystem lending platforms Navi and Scallop. Wave Digital Assets has committed to advancing a three-year Bitcoin yield bond tokenization plan on Sui after Hashi's mainnet launch. Hashi has not yet announced a mainnet launch date. Sui previously revealed the Hashi development phase in March, positioning the protocol as a solution to enhance capital efficiency in the approximately $1.4 trillion Bitcoin market.
