Fetching Block Gas Parameters

The gasParameters method allows you to retrieve gas metrics for the current block on the OP_NET network. These parameters include the total gas used, target gas limit, base gas price, and Exponential Moving Average (EMA) of gas prices.

---

Method

gasParameters(): Promise<BlockGasParameters>;

• Returns:
  • Promise<BlockGasParameters>: An object containing gas metrics for the current block.

Object Definitions

BlockGasParameters Object

Property	Type	Description
blockNumber	bigint	The number of the block being analyzed.
gasUsed	bigint	The total amount of gas used in the block.
targetGasLimit	bigint	The target gas limit for the block.
ema	bigint	The Exponential Moving Average of gas prices.
baseGas	bigint	The base gas price for the block.
gasPerSat	bigint	The amount of gas equivalent to one satoshi.

Example Usage

const gasParameters = await provider.gasParameters();

console.log("Block Gas Parameters:", gasParameters);
console.log("Block Number:", gasParameters.blockNumber);
console.log("Gas Used:", gasParameters.gasUsed);
console.log("Base Gas Price:", gasParameters.baseGas);

Best Practices

• Ensure your application dynamically adapts to changes in baseGas and gasPerSat for accurate transaction fee estimations.
• The gas parameters provide insights into the network's gas usage and pricing model, which is crucial for optimizing transaction costs.
