Bitcoin: Hashi Unlocks $1.4T BTC Collateral on Sui
Hashi, a Bitcoin finance native primitive on Sui developed by Mysten Labs, aims to use Bitcoin as programmable collateral without moving it from its native chain. It secures deposited assets with a 2-of-2 multisig and manages loan terms via Move smart contracts on the Sui chain. Hashi's testnet has reported 2M+ test deposits with over 25 partners testing. Mainnet launch is the next milestone, with potential to connect Bitcoin liquidity to Sui DeFi protocols.
