Sufficiency

Sub-claim "The new fee schedule replaced the previous pricing model and…": 20% covered by S1

Sufficiency

The source confirms a new fee schedule with volume tiers based on trailing 30-day volume, but it does not mention reductions in maker/taker rates for most tiers, and the effective date is September 20, 2022, not October 2022.

Re-evaluate

Sub-claim "The fee update introduced a new tiered fee structure based o…": 100% covered by S1 — The article explicitly states Coinbase Exchange will implement a new fee structure and that volume tiers are calculated based on trailing 30-day volume.

Re-evaluate

Sub-claim "The updated fees reduced maker and taker rates for most volu…": 10% covered — The article mentions lowering the monthly trading volume required for mid and upper tiers but does not mention maker/taker rate changes or specific benefits for high-volume traders.

Re-evaluate

Sub-claim "The new fee schedule replaced the previous pricing model and…": 50% covered by S1 — The article confirms a new fee schedule replacing the previous one, but states it was implemented on September 20, 2022, not October 2022.

Re-evaluate

Only the first claim is fully covered. The second claim is not supported by the gathered content, and none of the skipped sources appear relevant to Coinbase fee schedules. The third claim is partially covered but contradicted on the effective date; no skipped source addresses this either. Therefore, purchasing additional sources is not justified.

§ IIThe reading1 cited
Lowconfidence2 sub-claims remain below the evidence threshold

> ⚠ Low confidence — 2 sub-claims remain below the evidence threshold within budget. Treat this as provisional.

Based on the provided source, the key finding is that Coinbase Exchange implemented a new fee structure on September 20, 2022, which lowered the monthly trading volume required to qualify for the mid and upper tiers of the fee schedule. The calculation for volume tiers continues to be based on trailing 30-day volume .

The provided source does not contain specific information about the fee update introducing a new tiered fee structure based on 30-day trading volume (as opposed to modifying existing tiers), whether it reduced maker and taker rates for most volume tiers, or whether the new fee schedule replaced the previous pricing model and took effect in October 2022. Therefore, I cannot confirm these subclaims based solely on the provided text.
