Sui Launches Hashi Bitcoin DeFi Protocol to Unlock $BTC Utility

Sui, a scalable blockchain ecosystem, has unveiled Hashi, a unique Bitcoin finance primitive for institutional-level participation on-chain. Hashi offers a smart-contract-based, trustless model to permit retail and institutional users to get yield, borrow, and lend against Bitcoin ($BTC). As per Sui’s official announcement on X, the market cap of Bitcoin has surpassed $1T, yet DeFi uses its 0.5%, signifying a huge capital efficiency gap. So, Hashi attempts to change this with the provision of native $BTC deployment in borrowing, yield-generating, and lending opportunities.

Introducing Hashi: a new era of Bitcoin finance on Sui.

Bitcoin’s market cap exceeds $1 trillion. < 0.5% of it is used in DeFi.

Exclusive Sui Bitcoin Primitive ‘Hashi’ Unlocks Bitcoin Yield Strategies

Sui’s exclusive Hashi network’s launch on its devnet delivers cutting-edge and seamless Bitcoin finance for institutions. Industry leaders like BitGo, Ledger, Fordefi, FalconX, Erebor Bank, and Bullish have already announced their support for the exclusive project. The protocol allows $BTC-backed lending of stablecoins, automated management of collateral, and structural products. This makes it a basis layer to advance Bitcoin-based finance through Sui.

To start with, stablecoin and $BTC holders leveraging Fordefi, Cubist, Cobo, Blockdaemon, Ledger, and BitGo wallets can allocate assets for diverse yield-generating strategies. Particularly, lending will serve as the main use case, while Hashi will automate asset movement across chains between Sui and Bitcoin. Keeping this in view, builders will additionally get a flexible primitive to create unique financial products, such as improved reward mechanisms and a credit organization for retail and institutional markets.

Strengthening Bitcoin Credit Markets via Cross-Chain Efficiency and Transparent Collateral

As Sui puts it, Hashi permits users to originate credit while enjoying complete transparency, taking into account collateral safety, real-time borrower health statistics, and verifiable rates. CF standards will disseminate data via oracle ecosystems, whereas Cubist will drive $BTC movement as well as collateral efficiency. Overall, the initiative endeavors to establish a new standard benchmark for a transparent and secure Bitcoin-backed lending across worldwide markets.
