A new bitcoin lending system is set to debut with $500 million in commitments

The primary target for this capital is a massive pool of dormant wealth. Sui estimates that roughly $1 trillion worth of Bitcoin is currently sitting idle. Until now, institutional and corporate balance-sheet holders have lacked a compliant, transparent ecosystem to safely deploy their native Bitcoin in decentralized finance (DeFi).

This launch comes amid a broader shift in Bitcoin-backed finance, where borrowing is moving far beyond speculative crypto trading. Bitcoin holders now use bitcoin-collateralized loans to cover real-world expenses like university tuition, real estate acquisitions, and corporate working capital.

“Public companies and institutions hold enormous amounts of Bitcoin, but their ability to use that capital has been constrained by the technology available to them,” said Nathan McCauley, CEO and co-founder of Anchorage Digital, a day-one launch partner that also plans to supply stablecoin liquidity to the network.

“Connecting our institutional clients with Hashi represents a complete paradigm shift,” McCauley added.

Here’s how the system overcomes these institutional constraints. Instead of bridging across blockchains, users securely lock their BTC in a vault address directly on the Bitcoin blockchain. A 2-of-2 multisig secures this address, requiring cryptographic sign-off from both Hashi’s validators. Hashi also has a separate, independent guardian layer designed to monitor and slow suspicious collateral movements.
