useInfiniteReadContracts 
Hook for calling multiple contract read-only methods with "infinite scrolling"/"fetch more" support.
Import 
import { useInfiniteReadContracts } from 'wagmi'Usage 
The example below shows how to demonstrate how to fetch a set of mloot attributes (chestwear, footwear, and handwear) with "fetch more" support.
import { useInfiniteReadContracts } from 'wagmi'
import { abi } from './abi'
const mlootContractConfig = {
  address: '0x1dfe7ca09e99d10835bf73044a23b73fc20623df',
  abi,
} as const
function App() {
  const result = useInfiniteReadContracts({
    cacheKey: 'mlootAttributes',
    contracts(pageParam) {
      const args = [pageParam] as const
      return [
        { ...mlootContractConfig, functionName: 'getChest', args },
        { ...mlootContractConfig, functionName: 'getFoot', args },
        { ...mlootContractConfig, functionName: 'getHand', args },
      ]
    }
    query: {
      initialPageParam: 0,
      getNextPageParam: (_lastPage, _allPages, lastPageParam) => {
        return lastPageParam + 1
      }
    }
  })
}export const abi = [
  {
    inputs: [{ internalType: 'uint256', name: 'tokenId', type: 'uint256' }],
    name: 'getChest',
    outputs: [{ internalType: 'string', name: '', type: 'string' }],
    stateMutability: 'view',
    type: 'function',
  },
  {
    inputs: [{ internalType: 'uint256', name: 'tokenId', type: 'uint256' }],
    name: 'getFoot',
    outputs: [{ internalType: 'string', name: '', type: 'string' }],
    stateMutability: 'view',
    type: 'function',
  },
  {
    inputs: [{ internalType: 'uint256', name: 'tokenId', type: 'uint256' }],
    name: 'getHand',
    outputs: [{ internalType: 'string', name: '', type: 'string' }],
    stateMutability: 'view',
    type: 'function',
  },
] as constimport { http, createConfig } from 'wagmi'
import { mainnet, sepolia } from 'wagmi/chains'
export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})In the above example, we are setting a few things:
- cacheKey: A unique key to store the data in the cache.
- query.initialPageParam: An initial page parameter to use when fetching the first set of contracts.
- query.getNextPageParam: A function that returns the next page parameter to use when fetching the next set of contracts.
- contracts: A function that provides- pageParam(derived from the above) as an argument and expects to return an array of contracts.
Paginated Parameters 
We can also leverage properties like getNextPageParam with a custom limit variable to achieve "pagination" of parameters. For example, we can fetch the first 10 contract functions, then fetch the next 10 contract functions, and so on.
import { useInfiniteReadContracts } from 'wagmi'

})query 
TanStack Query parameters. See the TanStack Query query docs for more info.
Wagmi does not support passing all TanStack Query parameters
TanStack Query parameters, like queryFn and queryKey, are used internally to make Wagmi work and you cannot override them. Check out the source to see what parameters are not supported. All parameters listed below are supported.
enabled 
boolean | undefined
- Set this to falseto disable this query from automatically running.
- Can be used for Dependent Queries.
gcTime 
number | Infinity | undefined
- Defaults to 5 * 60 * 1000(5 minutes) orInfinityduring SSR
- The time in milliseconds that unused/inactive cache data remains in memory. When a query's cache becomes unused or inactive, that cache data will be garbage collected after this duration. When different garbage collection times are specified, the longest one will be used.
- If set to Infinity, will disable garbage collection
initialData 
InfiniteReadContractsData | (() => InfiniteReadContractsData) | undefined
- If set, this value will be used as the initial data for the query cache (as long as the query hasn't been created or cached yet)
- If set to a function, the function will be called once during the shared/root query initialization, and be expected to synchronously return the initialData
- Initial data is considered stale by default unless a staleTimehas been set.
- initialDatais persisted to the cache
initialDataUpdatedAt 
number | ((() => number | undefined)) | undefined
If set, this value will be used as the time (in milliseconds) of when the initialData itself was last updated.
initialPageParam 
number
The initial page parameter to be passed to the query function.
getPreviousPageParam 
This function can be set to automatically get the previous cursor for infinite queries. The result will also be used to determine the value of hasPreviousPage.
(firstPage: InfiniteReadContractsData, allPages: InfiniteReadContractsData[], firstPageParam: number, allPageParams: number[]) => number | undefined | null
getNextPageParam 
This function can be set to automatically get the previous cursor for infinite queries. The result will also be used to determine the value of hasPreviousPage.
(lastPage: InfiniteReadContractsData, allPages: InfiniteReadContractsData[], lastPageParam: number, allPageParams: number[]) => number | undefined | null
meta 
Record<string, unknown> | undefined
If set, stores additional information on the query cache entry that can be used as needed. It will be accessible wherever the query is available, and is also part of the QueryFunctionContext provided to the queryFn.
networkMode 
online' | 'always' | 'offlineFirst' | undefined
- Defaults to 'online'
- see Network Mode for more information.
notifyOnChangeProps 
string[] | 'all' | (() => string[] | 'all') | undefined
- If set, the component will only re-render if any of the listed properties change.
- If set to ['data', 'error']for example, the component will only re-render when thedataorerrorproperties change.
- If set to 'all', the component will opt-out of smart tracking and re-render whenever a query is updated.
- If set to a function, the function will be executed to compute the list of properties.
- By default, access to properties will be tracked, and the component will only re-render when one of the tracked properties change.
placeholderData 
InfiniteReadContractsData | ((previousValue: InfiniteReadContractsData | undefined; previousQuery: Query | undefined) => InfiniteReadContractsData) | undefined
- If set, this value will be used as the placeholder data for this particular query observer while the query is still in the pendingstate.
- placeholderDatais not persisted to the cache
- If you provide a function for placeholderData, as a first argument you will receive previously watched query data if available, and the second argument will be the complete previousQuery instance.
queryClient 
QueryClient | undefined
Use this to use a custom QueryClient. Otherwise, the one from the nearest context will be used.
refetchInterval 
number | false | ((data: InfiniteReadContractsData | undefined, query: Query) => number | false | undefined) | undefined
- If set to a number, all queries will continuously refetch at this frequency in milliseconds
- If set to a function, the function will be executed with the latest data and query to compute a frequency
refetchIntervalInBackground 
boolean | undefined
If set to true, queries that are set to continuously refetch with a refetchInterval will continue to refetch while their tab/window is in the background
refetchOnMount 
boolean | 'always' | ((query: Query) => boolean | 'always') | undefined
- Defaults to true
- If set to true, the query will refetch on mount if the data is stale.
- If set to false, the query will not refetch on mount.
- If set to 'always', the query will always refetch on mount.
- If set to a function, the function will be executed with the query to compute the value
refetchOnReconnect 
boolean | 'always' | ((query: Query) => boolean | 'always') | undefined
- Defaults to true
- If set to true, the query will refetch on reconnect if the data is stale.
- If set to false, the query will not refetch on reconnect.
- If set to 'always', the query will always refetch on reconnect.
- If set to a function, the function will be executed with the query to compute the value
refetchOnWindowFocus 
boolean | 'always' | ((query: Query) => boolean | 'always') | undefined
- Defaults to true
- If set to true, the query will refetch on window focus if the data is stale.
- If set to false, the query will not refetch on window focus.
- If set to 'always', the query will always refetch on window focus.
- If set to a function, the function will be executed with the query to compute the value
retry 
boolean | number | ((failureCount: number, error: ReadContractsErrorType) => boolean) | undefined
- If false, failed queries will not retry by default.
- If true, failed queries will retry infinitely.
- If set to a number, e.g.3, failed queries will retry until the failed query count meets that number.
- Defaults to 3on the client and0on the server
retryDelay 
number | ((retryAttempt: number, error: ReadContractsErrorType) => number) | undefined
- This function receives a retryAttemptinteger and the actual Error and returns the delay to apply before the next attempt in milliseconds.
- A function like attempt => Math.min(attempt > 1 ? 2 ** attempt * 1000 : 1000, 30 * 1000)applies exponential backoff.
- A function like attempt => attempt * 1000applies linear backoff.
retryOnMount 
boolean | undefined
If set to false, the query will not be retried on mount if it contains an error. Defaults to true.
select 
((data: InfiniteReadContractsData) => unknown) | undefined
This option can be used to transform or select a part of the data returned by the query function. It affects the returned data value, but does not affect what gets stored in the query cache.
staleTime 
number | Infinity | undefined
- Defaults to 0
- The time in milliseconds after data is considered stale. This value only applies to the hook it is defined on.
- If set to Infinity, the data will never be considered stale
structuralSharing 
boolean | (((oldData: InfiniteReadContractsData | undefined, newData: InfiniteReadContractsData) => InfiniteReadContractsData)) | undefined
- Defaults to true
- If set to false, structural sharing between query results will be disabled.
- If set to a function, the old and new data values will be passed through this function, which should combine them into resolved data for the query. This way, you can retain references from the old data to improve performance even when that data contains non-serializable values.
Return Type 
import { type UseInfiniteReadContractsReturnType } from 'wagmi'data 
InfiniteReadContractsData
- The last successfully resolved data for the query.
- Defaults to undefined.
dataUpdatedAt 
number
The timestamp for when the query most recently returned the status as 'success'.
error 
null | ReadContractsErrorType
- The error object for the query, if an error was thrown.
- Defaults to null
errorUpdatedAt 
number
The timestamp for when the query most recently returned the status as 'error'.
errorUpdateCount 
number
The sum of all errors.
failureCount 
number
- The failure count for the query.
- Incremented every time the query fails.
- Reset to 0when the query succeeds.
failureReason 
null | ReadContractsErrorType
- The failure reason for the query retry.
- Reset to nullwhen the query succeeds.

boolean
Will be true if the data in the cache is invalidated or if the data is older than the given staleTime.
refetch 
(options: { cancelRefetch?: boolean | undefined; throwOnError?: boolean | undefined }) => Promise<UseQueryResult<InfiniteReadContractsData, ReadContractsErrorType>>
- A function to manually refetch the query.
- throwOnError- When set to true, an error will be thrown if the query fails.
- When set to false, an error will be logged if the query fails.
 
- When set to
