Score: 61.0/100. Best raw efficiency in the series, tempered by cross-reseller weight, warranty, and voltage inconsistencies.

Kaiko – Crypto Data Aggregator Review

Score: 60.0/100. Massive institutional coverage and a real frontrunning catch, but its new investors include an exchange and two trading firms.

Bitquery – Crypto Data Aggregator Review

Score: 56.5/100. Unusually candid backend documentation, alongside an inconsistent founding date and a reported Binance investment.

GoldRush – Crypto Data Aggregator Review

Score: 64.5/100. A well-documented three-layer pipeline across 100+ chains, though its decoding logic is proprietary with no external review.

Pyth Network – Crypto Data Aggregator Review

Chainlink – Crypto Data Aggregator Review

Score: 69.25/100. The most battle-tested three-layer aggregation design in DeFi, tempered by disclosed LINK concentration under Chainlink Labs.
