This whitepaper introduces Klaster—a novel P2P network standard that enables guaranteed conditional execution of transactions across one or more independent blockchains with a single off-chain signature.
Key Concepts
- Interchain Transactions (iTx): A new transaction primitive using Merkle Trees of UserOperations that allows users to sign once and execute across multiple chains
- Klaster Protocol Execution Network (PEN): A peer-to-peer network of node operators responsible for executing interchain transactions with crypto-economic security guarantees
- ERC-4337 & ERC-7579 Compatibility: Built on battle-tested Account Abstraction infrastructure
Use Cases
- Gas-abstracted wallets
- Chain-abstracted dApps
- Multichain payment flows
- One-signature checkout flows
