Polygon PoS Gas Tracker

How fees work on Polygon PoS

Gas on Polygon PoS, now called Polygon Chain in its docs, is paid in POL, which replaced MATIC as the network's gas and staking token. Prices are quoted in gwei of POL. Blocks are produced by the Bor layer, while the Heimdall layer periodically publishes checkpoints of those blocks to Ethereum. Your fee depends on the gas your transaction uses and the gas price you set.

Polygon supports EIP-1559 through Type 2 transactions. The base fee is set automatically based on how full the previous block was, and it is burned. On top of it you pay a priority fee, calculated as the lower of your max priority fee and your max fee minus the base fee. Legacy Type 0 transactions still work, but they use a single gas price instead of separate fields.

Polygon Chain mainnet enforces a minimum priority fee of 25 gwei, so a tip below that value will not be accepted. The part of fees that is not burned goes to validators. Each block producer on Bor receives a percentage of the fees in its blocks, and the rest is shared among validators working at the Heimdall layer. This differs from Ethereum, where the full tip goes to one validator.

The Polygon Gas Station returns fee suggestions at three levels: safeLow for non-urgent transactions, standard for most use, and fast for quick inclusion. Each level includes a max priority fee and a max fee in gwei, along with the estimated base fee and block time. The mainnet endpoint is gasstation.polygon.technology/v2, and it builds estimates from the 10th, 25th, and 50th percentiles of tips over the last 15 blocks.

Fees rise when blocks fill up, since the base fee climbs after full blocks and users compete with higher tips. A practical tip is to use a Type 2 transaction with a max priority fee at or just above the 25 gwei minimum, check the Gas Station first, and pick the fast tier only when timing matters.

How we measure Polygon PoS gas

Every 5 minutes our server calls eth_feeHistory for the last 20 blocks on a live public Polygon PoS RPC endpoint (last: api.zan.top). Slow, standard and fast are the next block’s base fee plus the 25th, 50th and 75th percentile of priority tips paid in those blocks. Block use: 11% of the gas target on average.
