What is an Agent Gas Policy?

1 min read Updated

Rules for agent gas fee spending — maximum prices, per-transaction limits, total budgets preventing overpayment during network congestion.

WHY IT MATTERS

Gas is the hidden cost. During congestion, prices spike 100x. An agent ignoring gas can burn its budget on fees alone.

Policies set: max gas price (don't transact above X gwei), per-tx limits, budget allocation (max Y% to gas).

Smart policies consider timing — wait for lower prices if not urgent.

HOW POLICYLAYER USES THIS

PolicyLayer enforces gas policies — max prices, limits, and budgets keep infrastructure costs predictable.

FREQUENTLY ASKED QUESTIONS

Should gas count toward spending limits?
Usually yes. Gas is a real cost. PolicyLayer can track gas separately or include it in overall spending caps.
What about L2 gas?
L2 gas is much cheaper but still worth monitoring. On Base, typical gas is under $0.01, but it can spike during high demand.
EIP-1559 implications?
PolicyLayer supports both legacy and EIP-1559 gas pricing. Max fee per gas and priority fee can both be policy-controlled.
