Maestro Launches First Bitcoin-Native Institutional Credit Market

Austin, Texas — Maestro has officially launched Mezzamine, the first Bitcoin-native credit market for the mining economy, deploying its inaugural program with Sazmining, a Mining-as-a-Service provider powered entirely by renewable energy.

The facility allows institutional Bitcoin holders to deploy idle BTC and earn an estimated 8–9% BTC annual yield, backed directly by mining hashrate and rewards.

“New Bitcoins are mined every 10 minutes. With Mezzamine, BTC holders can earn and share block rewards with miners. We’ve built the first on-chain Bitcoin credit market, enabling native yield through institutional-grade instruments powered by real mining operations.” - Marvin Bertin, Co-Founder & CEO, Maestro

Closing the BTC Miner Financing Gap

While Bitcoin mining secures the network, the capital markets supporting miners remain underdeveloped. Historically, miners could only borrow USD against BTC or raise equity, leaving them exposed to currency risk, which contributed to widespread bankruptcies in 2022.

“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 operation like Sazmining, this is exactly what the industry has needed.” - Kent Halliburton, CEO, Sazmining

Mezzamine directly addresses this gap by connecting BTC holders seeking yield with miners seeking capital, creating a self-contained ecosystem for Bitcoin-native financing.

A New Class of BTC Structured Credit

Mezzamine introduces the first BTC-native structured credit facility, designed to align with mining profitability cycles and protect both miners and 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.” - Maestro Leadership

By integrating miner cycle-aware BTC pricing and fleet hedging, Mezzamine stabilizes loan performance across different market conditions, delivering predictable Bitcoin yield.

Sazmining operates over 4,000 renewable-powered rigs across Paraguay, Norway, and the Americas, generating approximately 1.75 BTC per week at 0.67 EH/s. The Mezzamine facility will fund additional rig deployment and site expansion over 12–18 months, all without fiat liabilities.

“Mezzamine leverages on-chain rails and Bitcoin liquidity to bridge capital financing, energy, and mining. This decentralizes mining, creates arbitrage opportunities for investors, and strengthens the Bitcoin network.” - Varderes Barsegyan, Co-Founder & CTO, Maestro

Pipeline and Platform Expansion

Maestro reports 1,500+ BTC in demand from qualified miners, including public companies and mid-sized operators. Future programs will feature an on-chain secondary market and tradable mining credit-backed instruments, creating a fully decentralized BTC credit ecosystem.

Eligibility: Institutional investors, corporate treasuries, asset managers, family offices, and registered investment advisers with a minimum allocation of $100,000 equivalent. KYC/AML onboarding required.
