Sufficiency

The gathered sources provide strong evidence that USDC settlement on blockchain is near-instantaneous (seconds to sub-second), while traditional rails are slower (multi-day delays). The sources also mention 24/7/365 operation and lower latency. All sub-claims are sufficiently covered.

Sufficiency

Stopping early — skipping 1 further paid fetch(es) to save budget.

Re-evaluate

All sub-claims already well-covered (sufficiency passed with 0 gaps) — skipping re-evaluation to save latency.

§ IIThe reading2 cited

Highconfidence— 2 sources corroborate it with every sub-claim covereddeep research

USDC settlement on blockchain is near-instantaneous, typically completing within seconds to minutes . In optimized environments like Arc, settlement can finalize in under a quarter second (median 178ms) . Traditional fintech payment rails (e.g., ACH, wire transfers) have settlement times ranging from same-day to several days and are limited by business days and hours . Thus, USDC settlement latency is generally lower than traditional fintech payment rails .
