Postquant Labs, the developer behind the quantum computing protocol quip.network, has announced the public launch of QuipSwap, a Bridgeless Swap Protocol designed to eliminate cross-chain security vulnerabilities and counter the cryptographic risks posed by advancing quantum computing.

The protocol is the industry's first mechanism for executing trustless cross-chain transactions without relying on bridges, oracles, or wrapped assets — infrastructure components that have historically served as the primary attack vectors behind billions of dollars in exploits. The 2022 breaches of the Ronin Network and Wormhole bridges, each of which resulted in losses running into the hundreds of millions of dollars, remain among the largest thefts in the industry's history.

Traditional cross-chain solutions depend on centralized intermediaries or smart contract bridges to move assets between isolated blockchains, creating persistent custody and manipulation risks. Wrapped assets add a further trust layer, since the token circulating on a destination chain depends on a custodian or authorized minter honoring its backing. QuipSwap departs from this model with a peer-to-peer architecture in which two counterparties agree to a swap and effectively exchange wallet access across chains through a synchronized, trustless process.

"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," Colton Dillion, CEO and co-founder of Postquant Labs, explained in a written statement.

"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," he added.

Quantum Resistance and Technical Validation

The launch comes amid growing urgency around quantum resistance. As quantum hardware matures, the cryptographic primitives securing current blockchains — most notably the elliptic-curve signatures underpinning networks such as Bitcoin and Ethereum — face potential compromise. Standardization efforts are moving in parallel: in 2024, the U.S. National Institute of Standards and Technology finalized its first post-quantum cryptography standards, giving the industry reference algorithms to migrate toward. Postquant Labs contends that isolated chain upgrades are inadequate because a transaction is only as secure as its weakest link; every intermediary layer must be quantum-resistant to guarantee end-to-end protection. Because no major blockchain currently supports native quantum computation and no existing bridge or exchange handles quantum-resistant transactions, the team built proprietary infrastructure to close the gap.

"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," said Dr. Richard Carback, Chief Technology Officer and co-founder of Postquant Labs, in a written statement. "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," he added.

Following a successful live claim demonstration at ETHDenver in February, the team finalized the core codebase and put the protocol through extensive testing alongside a formal security audit conducted by Oak Security, a blockchain security auditing firm.

Concurrently, quip.network has rolled out quantum-resistant wallets for Bitcoin, Ethereum, and Solana, presently in beta, to reinforce blockchain infrastructure against anticipated quantum threats. All research underpinning the network remains open-source, with the aim of establishing an industry-wide quantum computing standard that ensures long-term resilience across heterogeneous blockchain environments. With the wallets still in beta and QuipSwap newly public, open-source review and real-world usage of both are the practical tests now in front of the project.
