T+0 Settlement

T+0 settlement, also known as same-day settlement, refers to the process where the exchange of assets and the payment for those assets occur on the exact same day the trade is executed. In traditional finance, settlement cycles have historically been T+2 or T+3, meaning two or three business days pass before the legal transfer of ownership is finalized.

In the context of cryptocurrency and blockchain technology, T+0 is the default state because the atomic nature of transactions allows for instantaneous clearing and settlement upon the confirmation of a block. This mechanism eliminates counterparty risk, as the buyer does not have to wait for a clearinghouse to confirm the transfer, and the seller receives finality immediately.

By removing the time gap between execution and settlement, market participants reduce their exposure to price fluctuations that could occur during the waiting period. Furthermore, T+0 settlement significantly improves capital efficiency, as collateral and funds are not tied up in clearing queues, allowing traders to redeploy assets immediately.

It is a foundational pillar of decentralized finance that differentiates crypto markets from legacy equity markets.
