Sui will begin a phased mainnet rollout of Hashi later in October with more than $500 million in committed capital for Bitcoin-backed financial markets.
The infrastructure will let holders use native Bitcoin as collateral across lending, borrowing, credit, vaults and structured products on Sui. More than 20 companies have joined the launch coalition, with Anchorage Digital becoming the latest day-one partner.
Native BTC Will Back hBTC On Sui
Hashi keeps depositing Bitcoin secured on the Bitcoin network while minting a corresponding hBTC asset on Sui. That hBTC can then be used by applications built around the infrastructure. When users leave Hashi, the hBTC is burned and the underlying BTC is released.
The structure is intended to let Bitcoin function as programmable collateral without permanently moving the original asset onto another blockchain. The committed liquidity will support Hashi markets, including vaults operated by providers such as Aftermath, Concrete and Fluid.
Anchorage Adds Custody Routes and Stablecoin Liquidity
Anchorage Digital will give institutional clients two ways to access Hashi. One route will use Atlas, its settlement and tri-party collateral infrastructure, for institutions that need assets to remain within qualified custody arrangements.
A second will support direct participation through Anchorage’s institutional self-custody infrastructure.
Anchorage also plans to provide stablecoin liquidity, giving borrowers another source of capital against Bitcoin collateral. Other Hashi participants include BitGo, Bullish, Cumberland, FalconX and Ledger.
Hashi Mainnet Follows July Testnet Launch
Mysten Labs, the original contributor to Sui, developed Hashi as infrastructure for third-party lending platforms, vault providers and other financial applications.
Hashi moved to public testnet in July after an earlier devnet launch. Its security architecture combines multiparty computation, Sui smart contracts and a Guardian Layer that adds another check before Bitcoin collateral can leave the system.
Mainnet access will open progressively as participating companies complete integrations. Sui expects the phased rollout to begin later this month, putting more than $500 million in committed capital behind Hashi’s Bitcoin-backed markets as they move onto mainnet.
