| Abstrakt: | Platform-level gas fees serve as a public, real-time, predictive signal of cross-sectional liquidity risk in blockchain ecosystem tokens. Using a daily panel of 4,224 chain-specific tokens on Ethereum, BNB Chain, and Solana between 2017 and 2025 (2.04 million tokenday observations), gas fees are positively and significantly associated with token-level log Amihud illiquidity on every ecosystem after broad market illiquidity controls and two-way clustering on token and date. The magnitudes differ across chains in ways that line up with their fee-market designs and are economically substantial. A price-based native-token illiquidity factor also co-moves with chain-specific tokens, but the direct congestion measure is more robust to sample composition shifts and absorbs the price-based proxy on BNB Chain. Co-movement through returns and volatility is weak, consistent with the result running through trading frictions rather than expected returns or return variance. The institutional feature behind this result has no analogue in traditional markets, namely that execution costs in every chain-specific token are set in a single, system-level fee market for block space, paid in the chain’s native asset. Because gas fees are public, machine-readable, and available in real time, they offer a leading indicator for monitoring blockchain-market fragility. |
