Overview
- Sui announced on Oct. 8 that Hashi will start a phased mainnet rollout later in October backed by more than $500 million in capital commitments from a coalition of over 20 partners.
- Anchorage Digital joined the launch coalition and will give institutional clients two access routes through its Atlas tri‑party settlement system and Porto self‑custody wallet while also planning to supply stablecoin liquidity.
- Hashi keeps deposited Bitcoin on the Bitcoin blockchain and issues an hBTC token on Sui that is minted against deposited BTC and burned on exit to release the underlying coins.
- Security uses threshold cryptography with a 2‑of‑2 multisignature arrangement plus an independent guardian rate‑limiter, and Hashi’s smart contracts and MPC design have received third‑party reviews.
- The immediate next steps are partner integrations, converting pledged capital into on‑chain deposits, the first live hBTC mints and monitoring how the guardian rate‑limiter and vault integrations affect withdrawals under stress.
