Layer-2 Scaling & State Channel Framework

PolyCrypt provides production-ready Layer-2 blockchain scaling solutions through two flagship frameworks: Perun and Erdstall. These technologies enable developers and blockchain platforms to achieve massive scalability improvements while maintaining security and decentralization.

Perun State Channel Framework

Perun is an open-source off-chain framework built on state channel technology that enables real-time payments and complex business logic across multiple blockchains. As a Layer-2 solution, Perun allows transactions to execute off-chain while maintaining blockchain-backed security through cutting-edge cryptographic research. The framework provides unlimited scalability through instant, energy-efficient transactions with massively increased throughput, cross-chain functionality connecting users across different blockchain networks, provable security via virtual channel technology with state-of-the-art cryptographic guarantees, and unique offline payment capabilities supporting NFC and Bluetooth transactions without internet connectivity.

Erdstall Scaling Platform

Erdstall is a second-layer blockchain scaling solution that enables instant, gas-free, and confidential transactions on any blockchain. Built on smart contracts and an off-chain prover operating within a Trusted Execution Environment (TEE), Erdstall provides plug-and-play scaling technology delivering over 2000 transactions per second with zero gas costs for users and no on-chain checkpoints required. The platform eliminates gas fees for end users while providing instant finality and a trustless operator model, supports arbitrary smart contract execution (not limited to payments), offers privacy-by-default transaction handling, and enables easy user onboarding with superior performance.

Cross-Chain Capabilities

Through the Perun-X component, the framework enables trustless cross-chain asset exchanges between different blockchain networks without reliance on bridges or custodians. This capability leverages state channel technology to enable atomic swaps across blockchain networks with instant finality and cryptographic security guarantees, eliminating bridge security risks and dependency on custodial services.

Developer Offerings

Developers can leverage the Perun SDK (Go library) for full access to core state channel logic with customizable channel setup and settlement, deploy Perun Node for multi-user/device support in IoT environments, or integrate Erdstall as a plug-and-play scaling layer. The frameworks are modular and easily integrable with existing environments, designed for ultra-low latency applications, micropayment networks, embedded devices, identity solutions, and general application logic.

Supported Networks

Both platforms are blockchain-agnostic with demonstrated integrations across Ethereum, Polkadot, Cardano, Solana, Stellar, Internet Computer, and Nervos Network. The frameworks have been deployed in partnership with organizations including Bosch, Cardano Foundation, Web3 Foundation, and operate under Hyperledger Labs.

Use Cases

Typical implementations include real-time payment systems, offline payment networks, NFT marketplaces and trading platforms requiring high throughput, cross-chain asset swaps, autonomous agent economies, IoT micropayment infrastructure, DeFi protocols needing instant transactions with zero gas costs, gaming platforms, confidential NFTs (cNFTs), and decentralized applications requiring high throughput and low latency.
