Building the Decentralized Lending Desk Bitcoin Deserves

There is no institutional-scale way to borrow against bitcoin today that avoids reintroducing counterparty risk. Nearly 59% of BTC hasn’t moved in over a year because the conditions borrowers want (keep custody, borrow at scale, simple UI) are mutually incompatible in today’s market.

Centralized crypto lenders showed us one version of this failure. Companies like BlockFi, Celsius, and Genesis took BTC, promised yield, and rehypothecated customer collateral to fund their own positions. When the market turned, depositors discovered they weren't secured creditors with a claim on their Bitcoin.

Tradfi prime brokers operate the same way in a more formal wrapper. Rehypothecation is standard practice. Prime brokers will take pledged securities, repledge them in repo markets to borrow cash, and use that cash to extend more credit.  The collateral works, but it works for them. And if you're managing less than $500 million, they won't take your call anyway. 55% of traditional hedge funds now hold crypto exposure, and the average crypto hedge fund manages roughly $130 million. They're stuck using basic exchange accounts with no leverage. These middle-market institutions are too large for retail products and too small for Wall Street.

So the capital stays parked. The long-term holder with 5 BTC who needs a down payment won't hand keys to a company that might rehypothecate. The fund manager with $80M of Bitcoin at Anchorage can’t use DeFi without breaching custody rules, and Goldman won’t service them. Both end up holding an appreciating asset with no path to liquidity except selling.

How can we build institutional-scale credit against bitcoin without reintroducing the counterparty risk Bitcoin eliminates and abstracts away the complexity of defi?

Lending Desk 101

Since the emergence of modern prime brokerage in the 1970s, lending desks have bootstrapped using one of two approaches.

1. The Cantillon Model (Supply-Side Advantage): If you’re a bank or a prime broker backed by one, you start with privileged access to funding. You can tap central bank liquidity, create deposits when you lend, or borrow in repo markets at rates the broader market can’t match. This is the Cantillon dynamic in credit markets. Proximity to money creation confers a structural advantage. You concentrate supply first, let demand follow.
2. The Ownership Model (Alignment Advantage): If you don’t have privileged capital access, you give early capital providers a stake in the desk itself. The early suppliers become aligned with the desk’s long-term success.

A decentralized lending desk cannot use the traditional supply-side cheat. All Bitcoin lent must come from an actual holder. All yield paid must come from actual borrowers or explicit protocol incentives. Additionally, rehypothecation breaks the properties that make Bitcoin valuable as collateral. As such, a decentralized lending desk has to take the ownership route.

However, two-sided markets are notoriously difficult to start from scratch. Borrowers want depth before they commit. Lenders want utilization before they allocate. Neither side moves first without a reason to believe the other will follow.

In a decentralized desk launch, the capital providers become owners of the infrastructure itself. This allows for innovation in supply growth. Ownership gives early suppliers a reason to move first.

Mezo: A Decentralized Lending Desk for Bitcoin

That distinction matters because lending desks are fee businesses. In the traditional model, users provide capital and earn a rate, but the desk’s upside (i.e., how fees are routed, what products get prioritized, and who captures the spread) belongs to the operator and its shareholders.

Mezo inverts that. Instead of treating capital providers as depositors, it turns them into owners of the desk’s economics. When MEZO is locked, it gives holders a say over how the desk allocates incentives and fees, as well as a share of the fees. The supply side shows up because of ownership.

The lending product itself can and should stay boring. Boring is simple.

For the individual holder, that means one-click borrowing. Mezo abstracts the complexity so the user never has to learn bridges, swaps, or multi-step flows to access liquidity.

For the institution bound by custody mandates, the same credit economics arrive through custody-compatible rails. The collateral remains segregated at a qualified custodian, and credit is issued against it without the bitcoin leaving compliant custody. The fund manager gets Mezo prime rates (1% vs 5-8% a traditional prime broker would charge), while satisfying every audit and compliance requirement.

This is also why Mezo’s supply-side design is different from prime brokerage. Traditional prime brokers scale by financing one customer's short position with another customer's long position. When internal matching breaks, desks push the imbalance into external funding markets (repo and securities lending), which extends the chain of dependencies and can amplify stress when margin calls and unwind pressure hit.

Mezo replaces that hidden balance-sheet reuse with an explicit matching market expressed as explicit ownership and fee-routing rather than hidden balance-sheet reuse. Bitcoin lockers supply the collateral and earn base economics. MEZO lockers route fees to specific BTC positions in exchange for incentives or fee exposure. In Mezo, unmatched positions still work. A veBTC position without veMEZO votes earns a base yield rate.
