Austin, Texas, March 17th, 2026, Chainwire
Maestro today went live with Mezzamine, the Bitcoin-native credit market for the mining economy, deploying its first live program with Sazmining, a leading Mining-as-a-Service provider powered by 100% renewable energy. The facility allows institutional Bitcoin holders to deploy idle BTC and earn an estimated 8–9% BTC annual yield, backed by hashrate and delivered through mining rewards.
Mezzamine is the first open on-chain capital market for Bitcoiners: miners can tap into BTC growth capital to expand hashrate, and institutional investors can earn Bitcoin yield by financing hashrate mining. In doing so, it offers a native Proof-of-work yield akin to POS rewards.
New Bitcoins are mined every 10 min, with Mezzamine BTC holders can earn and share block rewards with miners. To achieve this, we've built the first on-chain Bitcoin credit market, enabling native yield through institutional-grade structured instruments powered by real mining operations” — Marvin Bertin, Co-Founder & CEO, Maestro
Addressing the BTC Miner Financing Gap
Bitcoin mining secures the network, yet the capital markets supporting the mining industry remain underdeveloped.
Historically, miners have had limited financing options: borrowing USD against BTC collateral or raising via equity, the latter largely available only to public companies. Because miners generate revenue in BTC while most liabilities are denominated in dollars, the industry has been exposed to persistent currency risks that repeatedly destabilized operators in market downturns, most notably in 2022, resulting in numerous miner bankruptcies.
The result is a structural gap in Bitcoin’s financial infrastructure: ample BTC capital is seeking yield, but most BTC credit products break down in bear markets.
A New Category of BTC Structured Credit
Mezzamine launched the first BTC-native structured credit facility that aligns with mining profitability cycles and provides bear market protection for miners and investors. The structured credit product integrates miner cycle-aware BTC price and miner fleet hedging to stabilize loan performance across market regimes.
With Mezzamine, mining operations deliver base yield across moderate and bullish markets, while embedded BTC hedging mechanisms protect investors in bear markets.
The structure intentionally shifts economics across the cycle: miners pay higher financing costs in bull markets in exchange for greater credit capacity and resiliency in bear markets.
"Mining is the only way to generate new bitcoin, and Mezzamine lets us finance that capability in bitcoin itself — no dilution, no fiat liabilities. For a 100% renewable mining operation like Sazmining, this is exactly the kind of capital structure the industry has needed." — Kent Halliburton, CEO, Sazmining
The Inaugural Program: Sazmining
Sazmining pioneered Bitcoin Mining-as-a-Service, earning Bitcoin revenue via a customer-aligned model, while managing the full mining stack for its customers across renewable-powered data centers in Paraguay, Norway, North America, and South America. Its operations currently span more than 4,000 mining rigs generating approximately 1.75 BTC per week at roughly 0.67 EH/s, with all facilities powered by hydropower and other carbon-free energy sources.
Sazmining grew 350% year-over-year in 2025 and is targeting 60% additional hashrate growth in 2026. The Mezzamine facility is designed to finance that expansion, funding new rig deployments and site acquisition over a 12-to-18-month horizon without requiring Sazmining to assume fiat-denominated liabilities.
"Mezzamine leverages the power of on-chain rails and Bitcoin liquidity to bridge the gap between capital financing, energy, and Bitcoin mining. As a result, mining will become more decentralized, creating arbitrage opportunities for investors and a more secure network for Bitcoiners." — Varderes Barsegyan, Co-Founder & CTO, Maestro
Pipeline and Platform Expansion
Maestro reports more than 1,500 BTC in borrower demand from qualified mining operators currently exploring financing. Eligible participants include publicly traded mining companies, mid-sized operators, and infrastructure providers.
As additional programs come online, Maestro plans to introduce an on-chain secondary market and tradable mining credit-backed instruments, where miners and BTC holders can participate in a decentralized capital market.
Eligibility and Access
The Sazmining program is open to institutional investors, corporate treasuries, asset managers, family offices, and registered investment advisers with a minimum allocation of $100,000 equivalent. All participants complete standard KYC/AML onboarding prior to deployment. The program is available to participants in eligible jurisdictions, subject to applicable regulatory requirements.
