Happy Friday, Maestros!

This is a different kind of newsletter this week. No external spotlight. Instead, we're sharing a milestone of our own: the first onchain BTC payment from Mezzamine's Sazmining loan landed on April 14th.

Meanwhile, Strategy executed a $2.54B BTC purchase, spot ETFs extended a five-day inflow streak, public miners dumped a record 32,000 BTC in Q1 as the AI pivot accelerates, American Bitcoin surged 12% after deploying 11,298 new ASICs in Alberta, and over 100 crypto firms pushed the Senate to finally move on market structure legislation.

Going to the Bitcoin Conference in Vegas? So are we. We’d love to meet and talk shop.

💡Proof of Payment: Mezzamine's First Onchain BTC Yield

On April 14th, the first BTC payment was transferred onchain to the Mezzamine loan contract. Fixed 9% APY. Paid in BTC.

No points. No promises. Just yield, backed by proof-of-work.

🧠 In One Line

Idle BTC just became a working asset. And now it’s proven.

🔍 Why This Payment Matters

The first payment isn’t symbolic, it’s validation.

Mining revenue is reaching lenders as designed.
The 9% target is being met in real BTC.
And the loan performs on mining economics, not price.

For institutions, that difference matters.

⚡ How It Works

Sazmining operates 4,000+ rigs, producing ~1.75 BTC per week across Paraguay, Norway, and North America.

A fixed share of that output is paid to the Mezzamine credit facility and distributed to lenders.

No fiat conversion.
No margin calls.
No currency mismatch.

📌 Investor Takeaway

The first payment closes the loop. Bitcoin credit, backed by real hashrate, settled onchain. The borrower pipeline now exceeds 1,500 BTC from mid-sized and publicly traded miners. New programs are coming.

🚀 Why It’s Trending

Miners sold 32,000+ BTC in Q1.
Hashprice is near cycle lows.

The industry needs capital that’s native to Bitcoin.

This is that structure.
