Anchorage opens a qualified-custody route for bitcoin treasury firms into Sui's Hashi

Depositing bitcoin into Hashi produces collateral on Sui. The cash a treasury company wants has to come from someone lending stablecoins there. Anchorage says it wants to add stablecoin liquidity to the network ^[8]. The $500 million is a set of promises, and Sui has not said how much of it will be in Hashi contracts on the first day, Cryptopolitan reported ^[9].

Sui sizes the opportunity generously. It says more than $1 trillion in bitcoin is largely going unused because institutions lack tools with the controls they need ^[20]. The launch pledges come to 0.05% of that ^[17]. Sui's existing DeFi is the closer comparison. Phantom said in August it would stop supporting the chain after its DeFi value locked fell below $1 billion ^[15], so $500 million, if all of it arrived, would equal more than half of that figure ^[18].

On the Atlas route the treasury company sells no bitcoin and does not deal with Sui contracts itself ^[5]. Anchorage, which says it is the first crypto bank in the US with a federal charter ^[7], stands between the balance sheet and the loan market. "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 and the limitations of the DeFi space," Nathan McCauley, Anchorage's CEO and co-founder, said ^[16].

The engineering has a longer record than the market does. Mysten Labs built the framework and has run a global testnet since July 22 ^[10]. Certora formally verified the smart contracts, and CommonPrefix reviewed the security of the MPC protocol ^[13].

If the pledges convert and Anchorage's stablecoins arrive in size, a treasury company borrows against bitcoin that never left qualified custody. Should hBTC be minted faster than lenders show up, the loan a company can raise is capped by markets that sat under $1 billion in August ^[15]. The third case is that the more than 20 pledging firms ^[3] are themselves the lenders, in which case depth arrives with the launch.

We think the custody design is the finished part of Hashi and lending depth is the open one. The third case is the counter-thesis, and it may hold. Our view is wrong if Sui reports first-phase contract balances close to the full $500 million ^[2] and hBTC loan markets fill without Anchorage having to seed them.
