Summary

Ethereum’s EIP-1559 fee market uses a single base fee that adjusts based on block utilization. Two active proposals extend this: EIP-8037 adds separate pricing for state creation vs. burst (compute) resources, and a minimum base fee floor proposal addresses the near-zero fee collapse expected after Fusaka-era blob scaling reduces congestion pressure. Empirical data (Jan 2025–Jan 2026) shows aggregate demand is highly inelastic (ε ≈ 0.175) while state demand is moderately elastic (εs ≈ 0.3–0.6).

EIP-1559 Fundamentals

The current single-dimension fee market:

  • Block target: 50% of max gas (e.g., 30M target in a 60M max block)
  • Base fee adjustment: ±12.5% per block depending on whether the previous block was above/below target
  • Priority fee: tip to the block proposer on top of base fee
  • Base fee is burned (deflationary pressure)

Problem: All gas is treated equally. A heavy SSTORE (state-creating) operation competes for the same fee space as a lightweight computation. This distorts incentives and makes it hard to price the two resource types separately.

EIP-8037: Multidimensional Fee Market

EIP-8037 introduces separate pricing for two resource dimensions:

  • State gas (S): gas for creating or expanding persistent state (SSTORE, account creation, contract deployment)
  • Burst gas (B): gas for transient computation (all other operations)

Three Aggregation Functions

The key design question is how to combine S and B into a single block limit constraint:

FunctionFormulaBehavior
SumS + B ≤ LSimple; current EIP-1559 equivalent
Maxmax(S, B) ≤ L/2Symmetric constraint; reduces burst throughput
BurstS ≤ L/2 and B ≤ LCaps state; allows full burst capacity

Analysis conclusion: Burst maximizes throughput — up to 8x block capacity for burst-heavy workloads — while keeping state creation bounded. It is the recommended aggregation function.

Repricing Multiplier

When resources are repriced separately, a multiplier m adjusts the relative price of state vs. burst. Setting m=2 (state costs 2× what burst costs) can be used to discourage state bloat without reducing throughput.

Empirical Price Elasticities (2026)

Data from January 2025–January 2026, including three gas limit increases (30M→36M→45M→60M):

Key Results

ResourceElasticityInterpretation
Aggregate demand (εagg)~0.175 (event-based)Highly inelastic; demand fills capacity
State share (η)~0.43 (long-run)Users substitute between state and burst based on price
State (εs)~0.3–0.6Moderately elastic
Burst (εb)~0.0–0.2Nearly inelastic

Critical finding: State and burst are strong substitutes (correlation ≈ -0.99). When capacity increases, demand expands to fill it. This is the capacity-constrained demand model, not independent demand.

Implication for EIP-8037: Setting a higher price for state (m > 1) will cause users to substitute away from state creation toward burst, with η ≈ 0.43 governing the substitution rate. Burst demand barely responds to price changes.

Recovery Formulas

From the estimated model parameters:

εs = εagg + (1 - q₀) × η  ≈ 0.51
εb = εagg - q₀ × η        ≈ 0.08

where q₀ ≈ 0.23 (baseline state share of total gas).

Minimum Base Fee Floor Proposal

Problem: Post-Fusaka blob scaling reduces blob fees to near zero. The EIP-1559 mechanism then adjusts the base fee downward as well. Projections show a potential 96.5% fee revenue collapse once blob capacity is fully expanded and blob fees absorb most demand.

Proposal: Add a hard floor: base_fee_t = max(b_min, f(base_fee_{t-1}, gas_t))

  • b_min = 1 gwei is the proposed minimum
  • Without the floor: base fees collapse toward zero when blocks are consistently under-full
  • With the floor: fee revenue remains positive even in low-congestion environments
  • Benefit: protects validator revenue and burn rate; prevents deflationary model from breaking

Tension: A hard floor means EIP-1559’s smooth adjustment can’t undercut it — it is a price floor, not a dynamic equilibrium. This distorts the fee market when demand is genuinely low.

Priority Fee Anomaly

From the MetaMask priority fee analysis (Mar 2026):

  • MetaMask sets a standard priority fee of 2 gwei — approximately 20× higher than needed in uncongested conditions
  • Correlation between MetaMask user priority fees and actual congestion: -0.0009 (essentially zero)
  • Users who delegate fee setting to wallets significantly overpay during normal conditions
  • This represents a $100M+ annual wealth transfer from users to validators

Implication: Priority fee standardization in wallets is a significant user experience and welfare issue, distinct from the base fee mechanism.

Latency and Fee Revenue

From the APR/latency study:

  • A 50–150ms reduction in block propagation latency → 0.66–1.97% APR uplift for validators
  • Mechanism: faster blocks → less missed attestations → better MEV bid capture
  • Builders in regions with lower latency earn disproportionately from timing advantages

Open Questions

  • Which aggregation function (Sum, Max, or Burst) should EIP-8037 adopt?
  • Should the state/burst price ratio be protocol-determined or market-determined?
  • Should the minimum base fee floor be 1 gwei or some other value?
  • How does EIP-8037 interact with the upcoming gas limit increases and parallel execution?
