News linked to both this project and an event.
Sui Foundation and Mysten Labs launched the Bitcoin mortgage protocol Hashi testnet on July 22, allowing 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 by a 2-of-2 multi-signature mechanism that requires simultaneous signatures from Hashi's multi-party computation validators and an independent Guardian Layer. Loan terms and collateral positions are recorded on-chain, allowing lenders to view the collateral backing. Over 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 the Hashi mainnet launch. Hashi has not yet announced a mainnet launch date. Sui previously unveiled the Hashi development network phase in March, positioning the protocol as a solution to improve capital efficiency for the approximately 1.4 trillion dollar Bitcoin market.
Scallop, a lending protocol in the Sui ecosystem, announced on X that a vulnerability was discovered in a subsidiary contract related to Scallop’s sSUI reward pool, resulting in the loss of approximately 150,000 SUI. The affected contract has been frozen. Scallop stated that its core contracts remain secure and only the sSUI reward pool is impacted; all other reward pools are unaffected and secure. Scallop will fully cover 100% of the losses and will release further updates as soon as possible.
