eth_gasPrice - Manta RPC Method

Get current gas price on Manta Pacific. Essential for transaction cost estimation for ZK-enabled DeFi, private identity verification, and modular ZK applications via Universal Circuits.

Returns the current gas price on Manta Pacific in wei.

Why Manta? Build on the modular ZK L2 with Celestia DA delivering the lowest fees for 200+ dApps with first L2 on Celestia mainnet, ZK-as-a-Service via Universal Circuits, Polygon CDK integration, and modular OP Stack architecture.

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 ZK-enabled DeFi, private identity verification, and modular ZK applications via Universal Circuits
