Atomicity

Atomicity guarantees enabled by Rome

Solana guarantees the execution of all transactions within a Rome transaction as atomic, meaning either all transactions that are part of this Rome transaction succeed or none of them succeed. It removes the risk of a transaction in the bundle reverting only on one chain.

This enables trust-less, non-custodial transactions for cross-rollup and cross-chain arbitrage, flash loans, and RWA applications.

Solana is the global state machine for rollups that use Rome, allowing the atomic composition, and ordering/execution of transactions.
