getNetworkParameters

A builder function that returns the interaction to get network parameters.

Network parameters contain important configuration information about the Flow network, including the chain ID, which is essential for signing transactions correctly. This information is crucial for ensuring transactions are submitted to the correct network.

Import

You can import the entire package and access the function:

_10

import * as fcl from '@onflow/fcl';

_10

_10

fcl.getNetworkParameters();

Or import directly the specific function:

_10

import { getNetworkParameters } from '@onflow/fcl';

_10

_10

getNetworkParameters();

Usage

_14

import * as fcl from '@onflow/fcl';

_14

_14

// Get network parameters to verify chain ID

_14

const params = await fcl.send([fcl.getNetworkParameters()]).then(fcl.decode);

_14

_14

console.log('Chain ID:', params.chainId);

_14

console.log('Network:', params.name);

_14

_14

// Use this to verify you're connected to the right network

_14

if (params.chainId === 'flow-mainnet') {

_14

console.log('Connected to Flow Mainnet');

_14

} else if (params.chainId === 'flow-testnet') {

_14

console.log('Connected to Flow Testnet');

_14

}

Returns

_10

export type InteractionBuilderFn = (

_10

ix: Interaction,

_10

) => Interaction | Promise<Interaction>;

A function that processes an interaction object
