Replying to @BTC_OS @LitecoinVM
Much love BOS team!
Thank you for all you do. Cracked devs fr fr!
Congrats to the @LitecoinVM team on the LiteForge testnet launch 🔥
LitVM is powered by BitcoinOS Grail, our zk-proof based bridge infrastructure. Grail lets users lock LTC on Litecoin L1 and receive fully-backed zkLTC.
Zero-knowledge proofs verify the correctness of Litecoin transactions directly, secured by math rather than assumptions.
Originally built for Bitcoin, Grail is now proving that BOS infrastructure extends across UTXO chains. The UTXO superchain is taking shape.

Welcome home, Cardano. 🤝
This unlocks FAR more than people realize for UTXO ecosystems. Bitcoin and Cardano working as one is no longer just an idea—it’s here, powered by @CharmsDev.
MAJOR kudos to the Charms team for all their hard work.

WE ARE SOLD OUT! 😭
My heart is on fire. Thank you to everyone who participated - you’re all incredible. It’s been real. This is what it looks like when a community comes together and actually builds something into existence.
Much love! Can't wait for you to see the reveal.

📍 Final update before we mint tomorrow.
🗓️ Mint Day/Time: March 17th, 3pm UTC.
🔗 Wallet Checker: lunalauncher.io/#bitcoinos-c…
▪ Please use the wallet checker to confirm your eligibility.
▪ Make sure your wallet is funded with $6-7 in BTC to cover mint fees (likely an overestimation).
▪ I will publish an article on X with step-by-step instructions, FAQs, and more when the mint goes live tomorrow.
🕐 The mint will unfold in 3 phases:
▪ Phase 1: GTD WL Holders
Guaranteed whitelist holders will have 48h to mint.
Begins: March 17th, 3pm UTC.
▪ Phase 2: First Come, First Serve
Users who did not secure a GTD whitelist spot may mint any remaining supply. You have 24h.
Begins: March 19th, 3pm UTC.
▪ Phase 3: Public Mint
If supply remains, the mint will open to everyone.
Begins: March 20th, 3pm UTC.
Cheers!
