Sui Lines Up $500 Million for Hashi Bitcoin Collateral Protocol Ahead of Mainnet

Sui is preparing to roll out Hashi in late October 2026, backed by over $500 million in capital commitments from more than 20 partners including Anchorage Digital. The institutional-grade infrastructure allows participants to use Bitcoin as collateral across decentralized finance applications without moving native assets off the Bitcoin network. Hashi anchors BTC in a 2-of-2 multisignature mechanism to mint hBTC voucher tokens on Sui. The protocol, which first launched its testnet on July 22, aims to activate portions of an estimated $1 trillion in dormant institutional Bitcoin.
