# Gas & Fees

> Curated transaction fee datasets across 55+ EVM chains and Solana on Dune

Dune's gas tables provide transaction-level fee data across 55+ EVM chains and Solana, including fee breakdowns (base fee, priority fee, L1 data fee for L2s), gas pricing, and validator/proposer identification.

## When to Use These Tables

* Analyze transaction costs across chains
* Compare gas pricing and fee structures between L1s and L2s
* Track fee revenue for validators and block proposers
* Understand fee breakdowns (base vs priority vs L1 data costs on rollups)
* Build gas cost estimators or optimize transaction timing

## Query Performance

`gas.fees` is a view over chain-specific incremental tables using `block_month` and `block_date` as partition keys.

```sql theme={null}
-- ✅ Good: chain + time filter
SELECT * FROM gas.fees
WHERE blockchain = 'ethereum'
  AND block_date = DATE '2025-02-01'

-- ✅ L2 analysis with month filter
SELECT * FROM gas.fees
WHERE blockchain = 'base'
  AND block_month >= DATE '2025-01-01'
```

## Methodology

Gas tables are maintained by Dune ([source code](https://github.com/duneanalytics/spellbook)). Each chain has its own underlying gas model reading from the chain's `transactions` table, enriched with native token pricing for USD values.

A key feature is the `tx_fee_breakdown` MAP column, which decomposes fees into their components. For L2s like Base, this breaks down into base fee, priority fee, and L1 data fee — enabling precise rollup cost analysis.

## Example Queries

**Average gas price by chain (today):**

```sql theme={null}
SELECT
  blockchain,
  AVG(tx_fee_usd) AS avg_fee_usd,
  APPROX_PERCENTILE(tx_fee_usd, 0.5) AS median_fee_usd,
  COUNT(*) AS num_transactions
FROM gas.fees
WHERE block_date = CURRENT_DATE
GROUP BY 1
ORDER BY 2 DESC
```

**L2 fee breakdown on Base (base fee vs L1 data cost):**

```sql theme={null}
SELECT
  date_trunc('day', block_time) AS day,
  SUM(tx_fee_breakdown['base_fee']) AS total_base_fee_eth,
  SUM(tx_fee_breakdown['l1_fee']) AS total_l1_fee_eth,
  SUM(tx_fee_usd) AS total_fee_usd
FROM gas.fees
WHERE blockchain = 'base'
  AND block_month >= DATE '2025-01-01'
GROUP BY 1
ORDER BY 1
```
