What is sub-second settlement?
Sub-second settlement means a payment is confirmed on-chain in less than one second — typically around 500 milliseconds on MoltPe's supported chains (Polygon PoS, Base, Tempo). This is fast enough for real-time API billing, agent-to-agent negotiation, and interactive UIs where waiting for settlement would break the experience. Compare to card rails (T+1 to T+7 business days), SWIFT (2-5 business days), or L1 Ethereum (12 seconds to hours depending on congestion). MoltPe is AI-native payment infrastructure that gives AI agents isolated wallets with programmable spending policies.
The short version
- ~500 ms on MoltPe chains: Polygon PoS, Base, and Tempo all finalize transactions fast enough to feel instant to agents and humans.
- Real-time workflows unlock: An agent can pay for an API call, wait for confirmation, and use the response in a single conversation turn.
- Cards and banks cannot do this: Traditional rails "authorize" instantly but settle days later, which creates chargeback risk and delayed finality.
In more detail
Settlement is the moment a payment is final and irreversible. For cards, authorization happens in milliseconds, but actual settlement takes days and remains subject to chargebacks for months. For SWIFT wires, settlement can take a full business week for cross-border transactions. For L1 Ethereum, settlement happens in 12 seconds per block, but getting enough block confirmations to be confident of finality can push waits to a minute or more during congestion, and gas spikes make it expensive.
For AI agent payments, none of those windows are usable. An agent that pays for an API call and then waits three days for settlement before trusting the response is not an agent — it's a paperwork machine. Sub-second settlement changes the shape of what's possible: the agent pays, the service verifies, the work happens, and the whole loop fits inside a normal request-response. Chained calls across multiple paid APIs become practical.
MoltPe runs on Polygon PoS, Base, and Tempo because those chains have the finality characteristics that make sub-second agent workflows realistic. The combination of fast finality, low fees, and gas abstraction is what turns USDC into a rail agents can actually use.
