Postquant Labs Launches the First Quantum Cross-Chain Swaps

Where traditional cross-chain solutions rely on centralized intermediaries or smart contract bridges to move assets between blockchains, Quip’s new protocol utilizes a peer-to-peer (P2P) mechanism that completely upsets the previous paradigm. The protocol enables two parties to agree to a swap and effectively exchange wallet access across chains in a synchronized, trustless manner.

Colton Dillion, CEO and co-founder of Postquant Labs, said:

“If one party claims their side of the trade, the counterparty immediately receives their claim key too—no take-backs. You can be on any chain and treat it like a P2P swap. No intermediaries holding your funds, no oracles to manipulate, no bridges to hack, and no endless waiting for quantum-resistant upgrades. It’s a huge win for everyone who isn’t a bad actor and eliminates several looming quantum threats. Users get to keep their favorite assets and strategies on their favorite chains while still participating in the Quip ecosystem, with full access to our quantum computer network no matter where they hold funds.”

The timing of this launch addresses a key, often-overlooked vulnerability: quantum resistance. As quantum computing advances, the cryptographic foundations of current blockchains are becoming open to exploitation. The Quip team argues that simply upgrading a single chain is insufficient since, for a transaction to be truly quantum-resistant, every layer it traverses must also be immune to quantum attacks.

Dr. Richard Carback, Chief Technology Officer and co-founder at Postquant Labs, said:

“You can’t run a distributed computation network where your own miners can break your cryptography. No chain supports quantum computation, so we had to build our own. No bridge or exchange supports quantum-resistant transactions either, so we had to fill the void.  Our bridgeless, peer-to-peer protocol sidesteps the problem entirely by removing the intermediaries that would otherwise need to be upgraded. It’s the only path to a truly secure, quantum network that you can access from anywhere”

Following a successful demonstration of the live claim process at ETHDenver in February, the Quip team has completed the core codebase. The protocol has undergone rigorous testing and a formal security audit conducted by Oak Security, with results announced as part of today’s public launch.

Alongside QuipSwap, quip.network has successfully deployed quantum-resistant wallets across Bitcoin, Ethereum, and Solana, currently in beta testing, hardening blockchain infrastructure against the quantum threat before it arrives. All research underpinning quip.network is open-source, built with the goal of establishing a global quantum computing standard for the industry.
