Atomic Settlement
A securities transaction settlement mechanism in which payment and securities delivery are completed simultaneously and indivisibly—either both legs succeed or both are fully reversed. It relies on the atomic execution of smart contracts, eliminating the risk of delivery-versus-payment failure.
Timeline (last 90 days)
Atomic settlement means payment and delivery are completed simultaneously in the same on-chain transaction, with the whole thing rolling back if either party fails; it is usually implemented via smart contracts on EVM chains, on the premise that the delivery result can be confirmed on-chain or by a verifiable oracle.
Atomic settlement refers to the simultaneous and inseparable completion of both legs of a transaction—payment and securities delivery—at the same moment, such that either both succeed or both are reversed.
Atomic settlement relies technically on the atomic execution of smart contracts, where a transaction is only finally committed to the ledger when both the cash token and the securities token simultaneously satisfy the exchange conditions.
Atomic settlement in cross-chain or cross-ledger scenarios requires additional interoperability protocols (such as Hash Time-Locked Contracts, HTLC, or trusted intermediary layers) to guarantee atomicity.
