Estimate gas fees - Polygon Developer Docs

Polygon zkEVM is deprecated. It is no longer recommended for new integrations and references on this page reflect historical context only. New chains and applications should use Polygon Chain or Polygon CDK.

Polygon Gas Station provides gas price recommendations for Polygon Chain mainnet and Amoy testnet. It queries the RPC for eth_feeHistory and computes the 10th, 25th, and 50th percentiles of priority fees across the last 15 blocks. These become the safeLow, standard, and fast predictions.

On Polygon Chain mainnet, a minimum priority fee of 25 gWei is required.

Field	Description
`safeLow`	Conservative fee estimate (GWei). Use for non-urgent transactions.
`standard`	Moderate fee estimate (GWei). Suitable for most transactions.
`fast`	Higher fee estimate (GWei). Use when faster inclusion is needed.
`estimatedBaseFee`	Current base fee in GWei.
`blockNumber`	The latest block mined when the recommendation was made.
`blockTime`	Average block time in seconds for the network.

Polygon Chain overview: how gas, finality, and the EIP-1559 base fee work on Polygon.
Polygon RPC endpoints: connect to the network from a wallet or backend.
Open Money Stack Payments API: if you’re estimating gas for payment flows, the OMS handles fee selection and gas accounting for you.
