eth_gasPrice

Returns the current gas price on Linea in wei.

Why Linea? Build on Consensys-backed zkEVM L2 with $1B+ TVL and 807% growth in 2025 with 15-30x lower fees than Ethereum mainnet, 6,200 TPS throughput, SWIFT integration with 12+ institutions, and $725M Consensys backing.

Use Cases

The eth_gasPrice method is essential for:

• Transaction pricing - Set appropriate gas prices
• Cost estimation - Calculate transaction costs before sending
• Gas monitoring - Track network congestion
• DeFi operations - Optimize costs for enterprise DeFi (Aave, Renzo), institutional cross-border payments via SWIFT pilots, and zkEVM-native applications

Parameters

This method accepts no parameters.
