eth_gasPrice
Polygon / https://triport.io/polygon
Minimum tier: Free
Last updated:
eth_gasPrice returns the node's current best estimate of the gas price on
Polygon mainnet (chain ID 0x89 / 137), encoded as a 0x-prefixed hexadecimal
string in wei. It takes no parameters. The value represents what the node
considers a competitive price for a legacy (pre-EIP-1559) transaction.
Use it when you need a single, simple gas-price figure — for example, when
constructing a legacy type: 0x0 transaction that carries a flat gasPrice
field, or for a quick fee-level readout in a dashboard.
Prefer EIP-1559 fee methods on Polygon. Since the Bhilai hardfork, Polygon
uses the EIP-1559 fee market (a per-block baseFeePerGas plus a priority tip),
so a single gasPrice value is a coarse fallback. For accurate fee estimation
on EIP-1559 transactions (maxFeePerGas / maxPriorityFeePerGas), use
eth_maxPriorityFeePerGas or
eth_feeHistory and add a tip. eth_gasPrice remains
useful for legacy transactions and for rough, human-readable estimates. Note
that Polygon gas prices typically sit well above Ethereum's — values around
30 gwei are common.
