baseFeebase fee=minBaseFeefloor×P4(degree-4 TaylorΣsum over constraintsbacklogi / (Ti × Wi)backlog over target × window)

How the fee works

The fee is the floor multiplied by P4(x), and x is the sum over the chain's constraints of each backlog divided by its target times its window. Long windows ratchet on the average demand, short ones spike on bursts and drain within seconds, and there are no tips to jump the queue. The explainer walks through all of it with robinhood-testnet's own floor and constraint set. How the fee works →

Fee flows

Fee accounts (sampled balances)

Balances are sampled once a minute; none yet.

A balance that drops is a withdrawal, not a refund. Total fees remain Σ gasUsed × baseFee. Receipt poster gas funds the L1 pricer pool; only compute gas is split between infrastructure and network by the minimum base fee in force at each block.

Fees per bucket (ETH), stacked by destination
  • floor to infra
  • congestion to network
  • poster fee to L1 pricer

L1

L1 pricer and attributed batch costs collapsed

L1 values arrive with the slow (60 s) sample.

The L1 pricer adapts its per-unit price so collected L1 fees match the spending ArbOS attributes to batch posters. The attributed amount combines Nitro's calldata and storage accounting, batch extra gas, the effective per-batch charge, and the ArbOS 50+ parent calldata floor. It is not the batch poster's Ethereum receipt total. With blobs and compression the cost per transaction is tiny, so gasUsedForL1 rounds to 0 on a normal transaction. Receipt gasUsedForL1 is the authoritative poster-gas input for allocating user fees.

L2 fees against ArbOS-attributed batch-posting cost (ETH per bucket, log scale)

  • L2 fees 0 ETH
  • ArbOS batch cost 0 ETH
No batch reports in this range.
