getBlock

A builder function that returns the interaction to get the latest block.

Use with 'fcl.atBlockId()' and 'fcl.atBlockHeight()' when building the interaction to get information for older blocks.

Consider using the pre-built interaction 'fcl.block(options)' if you do not need to pair with any other builders.

Block ID is SHA3-256 hash of the entire block payload. This hash is stored as an ID field on any block response object (ie. response from 'GetLatestBlock').

Block height expresses the height of the block on the chain. The latest block height increases by one for every valid block produced.

Import

You can import the entire package and access the function:

_10

import * as sdk from "@onflow/sdk"

_10

_10

sdk.getBlock(isSealed)

Or import directly the specific function:

_10

import { getBlock } from "@onflow/sdk"

_10

_10

getBlock(isSealed)

Usage

_10

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

_10

_10

const latestSealedBlock = await fcl.send([

_10

fcl.getBlock(true) // isSealed = true

_10

]).then(fcl.decode);

Parameters

isSealed (optional)

• Type: boolean
• Description: If the latest block should be sealed or not. See block states

export type InteractionBuilderFn = (

ix: Interaction

_10

) => Interaction | Promise<Interaction>
