cBTC: Post-Quantum Bitcoin Exposure

Bitcoin was built for the era of digital independence. But a new era demands new protection.

We don't want to argue about when exactly a quantum computer will break ECDSA. We want BTC holders to have a working option today.

That's why we're building cBTC — a quantum hedge for Bitcoin on the Cellframe platform.

This is not an attempt to "replace Bitcoin". It's a practical path for those who want quantum-safe exposure to BTC without unnecessary drama and without waiting for the market to eventually agree on something.

Why Cellframe

Because post-quantum cryptography is not in our roadmap or future plans — it's already live. Natively. NIST algorithms, hot-swappable without a hard fork, a unique two-level sharding architecture, UTXO model. No retrofitting. No 60–70% throughput drop.

What cBTC is

A snapshot of Bitcoin's UTXO set. The user proves ownership of their address — receives cBTC 1:1 to a post-quantum address on Cellframe. The original BTC stays with them.

This is not a wrapped token. It's a balance imprint, moved into a quantum-safe environment.

What this approach offers

cBTC is not designed as an abstract theory. Its architecture is built from day one for real use cases: storage, transfers, liquidity, DeFi, and treasury tools.

This doesn't mean everything is already running at full scale. But it means we're not building a "token for the sake of a token" — we're building a system that can become a real instrument as soon as the ecosystem gains sufficient liquidity and support.

The technology is ready. The next step is growth around it.

Room to maneuver

Our solution leaves freedom for both the user and Bitcoin as a project.

You can stay in cBTC as a standalone quantum-safe asset. You can return to classical BTC through dedicated redemption channels. And if the Bitcoin community ever adopts its own quantum-safe upgrade — we'll have a compatible path for that scenario as well.

We're not closing doors. We're creating a transition to where security already works.

If you believe in an idea of Bitcoin that looks beyond the current cycle — join us.

The post-quantum era does not begin with panic.

It begins with those who build it first.

#cBTC — a quantum hedge for Bitcoin on Cellframe. A solution that delivers.
