Briefings

Analysis of Ethereum execution data from July 2025 to October 2026 reveals that priority fees at the front of blocks increased by 9.5 to 12.3 times the average fee in the middle of blocks, while overall swap priority fees fell by 75% from 2025 to 2026. The primary driver of this shift was a decline in zero-tip transactions, which dropped from 17.8% to 8.8% of front-of-block swaps. Titan accounts for nearly half of these zero-tip transactions, while BuilderNet accounts for 10% of front zero-tip swaps. The data is sourced from TEMBRI execution data and Xatu canonical execution, covering 115,000 blocks across sixteen sampled days.

Key points

• Priority fees at the front of Ethereum blocks increased by 9.5 to 12.3 times the average priority fee in the middle of blocks between July 2025 and October 2026.
• Zero-tip transactions at the front of blocks decreased from 17.8% to 8.8% of total swaps, with Titan accounts for nearly half of these zero-tip transactions.

Context

This analysis uses execution data from TEMBRI and Xatu to measure priority fees, positions, and transaction classification across sixteen sampled days. The findings indicate a structural shift in block front payment dynamics driven by transaction type distribution and zero-tip transaction frequency.

Limitations

Data covers only sixteen sampled days with 115,000 blocks; execution data cannot distinguish between direct transfers to builders, bundled transactions, or builder-exclusive flows. Measurements are limited to execution data only, excluding mempool, relay, and direct-payment data which are in progress. Some values are ranges or medians, and uncertainty exists regarding builder-specific breakdowns.
