The Sui Foundation has introduced Hashi, a decentralized primitive designed to enable compliant, BTC-backed lending and yield opportunities for institutional and retail participants.
On 19 March 2026, the Sui Foundation announced the upcoming devnet launch of Hashi, a Sui-based primitive that integrates native bitcoin ( BTC) into onchain financial services. Industry giants including Bitgo, Bullish, FalconX, and Ledger have committed to the platform to unlock capital efficiency for the $1.4 trillion bitcoin market.
Hashi utilizes multi-party computation (MPC) and the ERC-3643 standard to allow users to lend or borrow against BTC without selling the underlying asset. The protocol features institutional-grade insurance from Soter and formal verification from security firms like Certora to ensure mathematical certainty and collateral safety.
Following the devnet phase, Hashi will move to mainnet where partners like Wave Digital plan to issue secured, rated bonds collateralized by bitcoin. Native Sui protocols such as Navi and Scallop will also provide immediate access to BTC-backed stablecoin loans for the broader community.
“Think of Hashi as the unlock for developers to design solutions opening access to trillions in BTC liquidity,” said Adeniyi Abiodun, Co-Founder and CPO of Mysten Labs.
