What is USDC's trust score?

USDC (Circle) scores 83/100 on OnChain Benchmark's Stablecoin Quality Rating — the Institutional Grade band, as of Aug 26, 2026 (methodology v1.4-stablecoin).

How is USDC's trust score calculated?

OnChain Benchmark scores USDC across four equally weighted dimensions, each out of 25: reserve quality (23/25), redemption depth (19/25), transparency (20/25), holder concentration (not published — holder base too large or too widely distributed to measure to ground truth). The 83/100 composite reflects the three measured dimensions, renormalized. The full rubric is published at onchainbenchmark.com/methodology.

What does the Institutional Grade band mean?

Under OnChain Benchmark methodology v1.4-stablecoin, stablecoin composite scores band as Verified (≥ 85), Institutional Grade (≥ 70), Monitored (60–69), Elevated Risk (40–59), and Flagged (below 40). USDC scores 83/100, placing it in the Institutional Grade band.
