Perun SDK & Wallet Infrastructure

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. The framework provides developer infrastructure through the Perun SDK (Go library) for full access to core state channel logic with customizable channel setup and settlement, and Perun Node for multi-user/device support in IoT environments.

Developer Infrastructure

The Perun SDK offers modular wallet functionality that can be integrated into Web3 applications, supporting agent-to-agent payments for autonomous AI systems, IoT micropayments, cross-chain swaps, and custom state channel logic integration. Developers gain access to:

• Customizable channel setup and settlement logic
• Multi-device wallet support for IoT environments
• Cross-chain payment capabilities via Perun-X
• Offline payment support (NFC and Bluetooth)
• State channel wallet integration for embedded devices

Threshold Cryptography Integration

PolyCrypt's threshold cryptography expertise enhances the Perun framework with distributed key management capabilities. The company develops threshold signature schemes (TSS) for multi-party wallet custody, multi-device wallet implementations supporting hardware and mobile clients, and secure key generation and rotation protocols. This enables wallet solutions where cryptographic operations require cooperation from multiple parties or devices, eliminating single points of failure in key management.

Technical Capabilities

The framework is designed for ultra-low latency applications, micropayment networks, embedded devices, identity solutions, and general application logic. It provides blockchain-agnostic development supporting Ethereum, Polkadot, Cardano, Solana, and other major networks. The modular architecture allows easy integration with existing environments while maintaining provable security via virtual channel technology with state-of-the-art cryptographic guarantees.

Use Cases

Typical implementations include real-time payment systems, offline payment networks, cross-chain asset swaps, autonomous agent economies, IoT micropayment infrastructure, multi-device wallet setups with threshold security, and decentralized applications requiring high throughput and low latency. The framework has been deployed in partnership with organizations including Bosch, Cardano, Polkadot, Solana, and operates under Hyperledger Labs.
