A C is thin but real. Real transfers and real wallets, sized small enough that leaving a position is the risk, not the entry. Heavy, sustained flow across a wide set of wallets. This is the top of the activity scale: liquidity is present right now, not historically.
For cbBTC specifically, the base median score is 5 across 198 tokens and the highest score on the chain is 94. cbBTC sits +46 against that median, and it is one of 9 base tokens currently graded C.
The scanner reads transfer logs for the contract over the last 500 blocks and counts transfers, distinct sending and receiving wallets, mints, burns, and the share held by the largest wallet. Blocks are pulled in chunks against a private Alchemy endpoint with public gateways only as fallback, and coverage is recorded per call: if the reads do not cover the window, the response says PARTIAL instead of inventing a quiet token.
A 500-block window means different wall-clock time per chain. On Base that is the recent past rather than a daily average, which is the point: activity is the one thing a price chart cannot show you and a token list cannot fake.
Verdict, $0.02. The same measurement on demand for cbBTC or any contract, with the transfer count, wallet count, mint and burn activity, concentration, and a plain-English bottom line.
