Klaster

Klaster is an execution protocol in the chain abstraction space that aims to complete a set of operations across several chains with one signature. It bundles multichain actions into an iTx: a group of UserOperations arranged as a Merkle tree, where the user signs only the root hash and each leaf maps to a specific call on a specific chain.

Execution is handled by a public network whose nodes must stake to accept work, quoting the combined gas and fee across chains, executing as committed and facing slashing if they fail. On the account side it plugs in as an ERC-7579 module for Safe, Biconomy and ZeroDev implementations, with ERC-4337 providing the abstraction layer and undeployed accounts created lazily at precomputed addresses. Cross-chain rebalancing or borrowing thus collapses into one confirmation, with gas payable in assets on any chain.
