Quip Network says it has launched a new Bitcoin wallet architecture that adds post-quantum account protection through Arch Network, a smart-contract layer designed to stay anchored to Bitcoin. The pitch is straightforward: give users a way to move toward quantum-resistant signing without waiting for a Bitcoin soft fork or broader consensus upgrade.

What launched

According to Quip's announcement, the system commits a post-quantum public key to Bitcoin via Arch and uses WOTS+ (Winternitz One-Time Signatures) alongside existing Bitcoin signatures. The company says its arch-sdk is already available, while a consumer wallet app is scheduled to launch next week.

That timing matters because Bitcoin developers are already arguing over how to handle future quantum risk. CoinDesk notes that BIP-361 would eventually phase out quantum-vulnerable addresses on a fixed timeline, while Quip is positioning its wallet as an opt-in path that works on top of Bitcoin as it exists today.

What is verified so far

The conservative version is narrower than the marketing copy. Quip has publicly announced the product, identified Arch Network as the underlying execution layer, and said a third-party audit is still in progress. CoinDesk separately reported that the Bitcoin deployment is new and that the wallet app is not live until next week.

So the real news is not that Bitcoin's quantum problem is solved. It is that a new wallet project is trying to ship near-term, layer-two-based protection before the base layer reaches consensus on a protocol-wide migration path.
