Postquant Labs has announced the launch of QuipSwap, a bridgeless protocol designed to enable trustless peer-to-peer cross-chain asset swaps without bridges, oracles, or wrapped tokens.
Key Takeaways
QuipSwap enables trustless P2P cross-chain swaps without bridges, oracles, or wrapped assets
The protocol uses synchronized P2P wallet access exchange via claim key mechanisms
Quantum-resistant wallets deployed across Bitcoin, Ethereum, and Solana in beta
Formal security audit completed by Oak Security after ETHDenver demonstration
Bridgeless Protocol Addresses Cross-Chain Security
Postquant Labs, the developer behind quantum computing protocol quip.network, has announced the public launch of QuipSwap, its Bridgeless Swap Protocol. The protocol represents the first solution to enable trustless cross-chain transactions without bridges, oracles, or wrapped assets, components that have historically been the primary vectors for billions of dollars in losses from hacks and exploits. Where traditional cross-chain solutions rely on centralized intermediaries or smart contract bridges to move assets between blockchains, QuipSwap utilizes a peer-to-peer mechanism. The protocol enables two parties to agree to a swap and effectively exchange wallet access across chains in a synchronized, trustless manner. This connects to the broader cross-chain security landscape covered in CoinGecko's $3.63B crypto hacks report and Bitcoin's quantum fix proposal.
Synchronized P2P Swap Mechanism
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.

The timing of this launch addresses a key 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, CTO and co-founder, emphasized that the company's approach to quantum computing infrastructure is designed to address security challenges that arise when distributed networks rely on cryptographic systems vulnerable to quantum attacks.
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.
— Dr. Richard Carback, CTO and co-founder of Postquant Labs
Security Audit and ETHDenver Demonstration
Following a successful demonstration of the live claim process at ETHDenver in February, the Quip team 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 the public launch. Alongside QuipSwap, quip.network has successfully deployed quantum-resistant wallets across Bitcoin, Ethereum, and Solana, currently in beta testing. All research underpinning quip.network is open-source, built with the goal of establishing a global quantum computing standard for the industry. This connects to the Bitcoin's first quantum-safe transaction.
Looking Ahead
The launch of QuipSwap represents a significant step toward addressing two of the most pressing challenges in blockchain technology: cross-chain security and quantum resistance. By eliminating the need for bridges and oracles, the protocol removes the attack vectors that have accounted for billions in losses. The quantum-resistant wallets deployed across Bitcoin, Ethereum, and Solana could provide a foundation for securing blockchain infrastructure against future quantum computing threats.
