Atomicity

The property that ensures all parts of a cross-rollup transaction either succeed completely or fail completely, preventing partial execution.

Smart contracts that enable cross-rollup message passing through simple read/write interfaces for dApp communication.

The ability to combine different dApps and protocols across multiple rollups to create complex, interconnected workflows.

A coordination layer that manages cross-rollup transactions and ensures atomic execution using two-phase commit protocols.

A distributed consensus protocol that coordinates atomic execution across multiple rollups by collecting votes before committing transactions.

Transactions that span multiple rollups and execute atomically, enabling complex workflows across different chains.

A token standard that enables seamless asset bridging across OP Stack chains with unified liquidity and fungibility.

The infrastructure component that handles asset transfers between rollups while maintaining atomicity guarantees.

A Layer 2 scaling solution that processes transactions off-chain and submits proofs to the main chain.

Zero-knowledge proofs used for verifying transaction validity without revealing transaction details.

The problem of having separate, isolated liquidity pools on different chains instead of unified pools.

Total Value Locked that is consolidated across multiple rollups rather than fragmented on individual chains.
