Solana Earns $603M in 2025 Blockchain Fees (on-chain transaction costs)—Nansen

The assessment is "likely_true" with high confidence based on strong, consistent evidence from multiple primary sources. Two sources, one from Phemex News and another from the crypto exchange HTX, directly and explicitly attribute the claim to Nansen. They state that according to Nansen, Solana's on-chain fee revenue was $603 million in 2025. This provides direct confirmation of every component of the user's statement.Furthermore, several other sources, including posts on Binance's and Futu's platforms, corroborate the core data point, reporting that Solana's fee revenue for 2025 was indeed $603 million. While these specific summaries do not mention Nansen as the source, the consistency of the exact monetary figure across multiple independent reports strongly suggests they are all referencing the same underlying data. The fact that the most explicit sources name Nansen as the origin makes it highly probable that it is the correct attribution.There is no contradictory evidence among the provided sources. No source refutes the $603 million figure or the attribution to Nansen. The combination of direct attribution by multiple sources and widespread corroboration of the specific data makes the original statement very credible.
