</div><a rel="noopener noreferrer nofollow">Mezo</a>, the Bitcoin-native finance platform built by venture studio Thesis, has launched Mezo Prime — an institutional product designed to give corporate treasuries and other professional Bitcoin holders access to on-chain yield and borrowing without leaving regulated custody. The product is built in partnership with Anchorage Digital Bank, with Bullish (NYSE: BLSH) as the core launch customer and a 250 BTC anchor allocation. 
<h2 id="what-mezo-prime-offers">What Mezo Prime offers</h2> Mezo Prime is targeted at firms that hold Bitcoin but, until now, have largely had to choose between leaving it idle in custody or using arrangements that fall short of institutional control, reporting and risk standards. The product addresses that gap through a structure called "Enclaves" — segregated Bitcoin vaults isolated per depositor, with no commingling of assets across accounts and no rehypothecation. Custody is provided by Anchorage Digital Bank, the first federally chartered digital asset bank in the United States, and Mezo Prime is available directly through the Anchorage Digital platform to its existing institutional client base. Bitcoin held in an Enclave can be locked as veBTC to collect protocol fees in BTC, or used as collateral to borrow Mezo's Bitcoin-backed stablecoin <a href="https://financefeeds.com/tag/stablecoins/" rel="noopener noreferrer nofollow">MUSD</a> at a fixed rate. 
<h2 id="bullish-takes-250-btc-anchor-position">Bullish takes 250 BTC anchor position</h2> Bullish, the institutional digital asset exchange that <a href="https://www.bullish.com/" rel="noopener noreferrer nofollow">went public on the NYSE</a> and which acquired CoinDesk in 2023, is the first institution to participate in the product. The exchange has invested 250 BTC into Mezo and will deploy part of its corporate Bitcoin treasury through Mezo Prime while keeping the assets within its existing custody and compliance perimeter. "Bullish was built on the belief that institutional standards and digital asset participation aren't in conflict, and we're delighted to work with Mezo as a launch customer," said Tarun Kapoor, Vice President at Bullish. He singled out the veBTC design as "a great example of that philosophy in practice — mitigating smart contract risk and keeping the underlying BTC secure." 
<h2 id="closing-the-corporate-treasury-gap">Closing the corporate treasury gap</h2> Matt Luongo, co-founder of Mezo and Chief Executive Officer of Thesis, framed the product around the volume of Bitcoin sitting unused on corporate balance sheets. "Over a million Bitcoin sits on corporate balance sheets today, and almost none of it is working," Luongo said. "Mezo Prime changes that. Segregated custody through Anchorage Digital Bank, no rehypothecation, real yield from protocol activity." Nathan McCauley, Co-Founder and Chief Executive Officer of Anchorage Digital, positioned Mezo Prime as a way to bring secure custody and on-chain yield into a single product. "Institutions want to do more with their Bitcoin, but not at the expense of security and control," McCauley said. "Mezo Prime delivers both secure, segregated custody and direct access to on-chain yield in one platform." 
<h2 id="context-mezo-s-institutional-build-out">Context: Mezo's institutional build-out</h2> Mezo Prime is the latest step in a sustained push by Mezo to court institutional Bitcoin holders. The protocol's mainnet went live in May 2025, the MEZO token generation event was completed on 1 April 2026, and on 21 April 2026 MEZO and MUSD <a href="https://mezo.org/blog/mezo-and-musd-are-live-on-bullish-exchange" rel="noopener noreferrer nofollow">listed on Bullish Exchange</a> for institutional and retail trading. Mezo's earlier Anchorage Digital partnership in November 2025 enabled BTC-backed borrowing through Anchorage's Porto self-custody wallet at a 1% fixed rate; Mezo Prime extends that relationship into Anchorage Digital Bank's qualified custody. Mezo's wider product stack includes MUSD, a 100% Bitcoin-backed stablecoin issued against overcollateralised CDPs; veBTC, the yield-bearing Bitcoin position backed by protocol fees; and a native DEX for swaps and liquidity. According to Mezo, the protocol has processed over US$550 million in lifetime MUSD volume and issued more than 2,000 loans, with collateralisation exceeding 168%. 
<h2 id="faq">FAQ</h2><strong>What is Mezo Prime?</strong> Mezo Prime is an institutional Bitcoin yield and lending product launched by Mezo in partnership with Anchorage Digital Bank. It provides segregated "Enclave" vaults — isolated per depositor, with no commingling and no rehypothecation — that can be used to earn protocol fees through veBTC or to mint MUSD, Mezo's Bitcoin-backed stablecoin, against locked BTC collateral. <strong>Who can access Mezo Prime?</strong> The product is available now to Anchorage Digital Bank clients and is delivered directly through the Anchorage Digital platform. Bullish is the launch customer, investing 250 BTC and deploying a portion of its corporate Bitcoin treasury through the product while keeping the assets within its existing custody and compliance infrastructure. <strong>How is Mezo Prime different from Mezo's earlier Anchorage integration?</strong> Mezo's November 2025 partnership with Anchorage Digital enabled institutional borrowing on Mezo through the Porto self-custody wallet at a 1% fixed rate. Mezo Prime extends that integration into Anchorage Digital Bank's qualified custody, with isolated Enclave vaults engineered specifically for treasuries and other professional holders that require segregated custody, no rehypothecation, and audit-grade reporting. Mezo Prime tests a thesis the wider Bitcoin DeFi sector has been working toward for two years: that institutional capital will move on-chain when, and only when, qualified custody, segregation, and protocol yield can be delivered through the same product. Bullish's 250 BTC anchor is a meaningful first datapoint. Whether Mezo Prime converts that into wider corporate treasury allocation — beyond crypto-native firms — will be the practical test through the rest of 2026.
