    Gets address for ENS name.

    • Docs: https://viem.sh/docs/ens/actions/getEnsAddress
    • Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/ens

    Remarks

    Calls resolve(bytes, bytes) on ENS Universal Resolver Contract.

    Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to normalize ENS names with UTS-46 normalization before passing them to getEnsAddress. You can use the built-in normalize function for this.

    Example

    import { createPublicClient, http } from 'viem'
    import { mainnet } from 'viem/chains'
    import { normalize } from 'viem/ens'
    
    const client = createPublicClient({

    • Docs: https://viem.sh/docs/ens/actions/getEnsAvatar
    • Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/ens

    • Docs: https://viem.sh/docs/actions/public/getFilterChanges

    • If the filter was created with createContractEventFilter or createEventFilter, it returns a list of logs.
    • If the filter was created with createPendingTransactionFilter, it returns a list of transaction hashes.
    • If the filter was created with createBlockFilter, it returns a list of block hashes.

  • readContract: <

        | readonly unknown[],

        const args extends unknown,
    >(
        args: ReadContractParameters<abi, functionName, args>,
    ) => Promise<ReadContractReturnType<abi, functionName, args>>

    Calls a read-only function on a contract, and returns the response.

    • Docs: https://viem.sh/docs/contract/readContract
    • Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/contracts_reading-contracts

    Remarks

    A "read-only" function (constant function) on a Solidity contract is denoted by a view or pure keyword. They can only read the state of the contract, and cannot make any changes to it. Since read-only methods do not change the state of the contract, they do not require any gas to be executed, and can be called by any user without the need to pay for gas.

    Internally, uses a Public Client to call the call action with ABI-encoded data.

    Example

    import { createPublicClient, http, parseAbi } from 'viem'
    import { mainnet } from 'viem/chains'
    import { readContract } from 'viem/contract'
    
    const client = createPublicClient({

    • Docs: https://viem.sh/docs/actions/public/waitForTransactionReceipt
    • Example: https://stackblitz.com/github/wevm/viem/tree/main/examples/transactions_sending-transactions
    • JSON-RPC Methods:
      • Polls eth_getTransactionReceipt on each block until it has been processed.
      • If a Transaction has been replaced:
        • Calls eth_getBlockByNumber and extracts the transactions
        • Checks if one of the Transactions is a replacement
        • If so, calls eth_getTransactionReceipt.

    Remarks

    The waitForTransactionReceipt action additionally supports Replacement detection (e.g. sped up Transactions).

    Transactions can be replaced when a user modifies their transaction in their wallet (to speed up or cancel). Transactions are replaced when they are sent from the same nonce.

    There are 3 types of Transaction Replacement reasons:

    • repriced: The gas price has been modified (e.g. different maxFeePerGas)
    • cancelled: The Transaction has been cancelled (e.g. value === 0n)
    • replaced: The Transaction has been replaced (e.g. different value or data)

    Example

    import { createPublicClient, http } from 'viem'
    import { mainnet } from 'viem/chains'
    
    const client = createPublicClient({
      chain: mainnet,
      transport: http(),
    })
    const transactionReceipt = await client.waitForTransactionReceipt({
      hash: '0x4ca7ee652d57678f26e887c149ab0735f41de37bcad58c9f6d3ed5824f15b74d',

  • watchBlockNumber: (args: WatchBlockNumberParameters) => WatchBlockNumberReturnType

    Watches and returns incoming block numbers.

    • Docs: https://viem.sh/docs/actions/public/watchBlockNumber
    • Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/blocks_watching-blocks
    • JSON-RPC Methods:
      • When poll: true, calls eth_blockNumber on a polling interval.
      • When poll: false & WebSocket Transport, uses a WebSocket subscription via eth_subscribe and the "newHeads" event.

    Example

    import { createPublicClient, http } from 'viem'
    import { mainnet } from 'viem/chains'
    
    const client = createPublicClient({
      chain: mainnet,
      transport: http(),
    })
    const unwatch = await client.watchBlockNumber({
      onBlockNumber: (blockNumber) => console.log(blockNumber),
    })
    Copy

  • watchBlocks: <
        includeTransactions extends boolean = false,
        blockTag extends BlockTag = "latest",
    >(
        args: WatchBlocksParameters<
            Transport,
            undefined
            | Chain,
            includeTransactions,
            blockTag,
        >,
    ) => WatchBlocksReturnType

    Watches and returns information for incoming blocks.

    • Docs: https://viem.sh/docs/actions/public/watchBlocks
    • Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/blocks_watching-blocks
    • JSON-RPC Methods:
      • When poll: true, calls eth_getBlockByNumber on a polling interval.
      • When poll: false & WebSocket Transport, uses a WebSocket subscription via eth_subscribe and the "newHeads" event.

    Example

    import { createPublicClient, http } from 'viem'
    import { mainnet } from 'viem/chains'
    
    const client = createPublicClient({
      chain: mainnet,
      transport: http(),
    })
    const unwatch = await client.watchBlocks({
      onBlock: (block) => console.log(block),
    })
    Copy

  • watchContractEvent: <
        const abi extends Abi
        | readonly unknown[],
        eventName extends string,
        strict extends undefined | boolean = undefined,
    >(
        args: WatchContractEventParameters<abi, eventName, strict, Transport>,
    ) => WatchContractEventReturnType

    Watches and returns emitted contract event logs.

    • Docs: https://viem.sh/docs/contract/watchContractEvent

    Remarks

    This Action will batch up all the event logs found within the pollingInterval, and invoke them via onLogs.

    watchContractEvent will attempt to create an Event Filter and listen to changes to the Filter per polling interval, however, if the RPC Provider does not support Filters (e.g. eth_newFilter), then watchContractEvent will fall back to using getLogs instead.

    Example

    import { createPublicClient, http, parseAbi } from 'viem'
    import { mainnet } from 'viem/chains'
    
    const client = createPublicClient({
      chain: mainnet,
      transport: http(),
    })
    const unwatch = client.watchContractEvent({
      address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
      abi: parseAbi(['event Transfer(address indexed from, address indexed to, uint256 value)']),
      eventName: 'Transfer',
      args: { from: '0xc961145a54C96E3aE9bAA048c4F4D6b04C13916b' },
      onLogs: (logs) => console.log(logs),

  • watchEvent: <

        strict extends undefined
        | boolean = undefined,
    >(
        args: WatchEventParameters<abiEvent, abiEvents, strict, Transport>,
    ) => WatchEventReturnType

    Watches and returns emitted Event Logs.

    • Docs: https://viem.sh/docs/actions/public/watchEvent
    • JSON-RPC Methods:
      • RPC Provider supports eth_newFilter:
        • Calls eth_newFilter to create a filter (called on initialize).
        • On a polling interval, it will call eth_getFilterChanges.
      • RPC Provider does not support eth_newFilter:
        • Calls eth_getLogs for each block between the polling interval.

    Remarks

    This Action will batch up all the Event Logs found within the pollingInterval, and invoke them via onLogs.

    watchEvent will attempt to create an Event Filter and listen to changes to the Filter per polling interval, however, if the RPC Provider does not support Filters (e.g. eth_newFilter), then watchEvent will fall back to using getLogs instead.

  • watchPendingTransactions: (
        args: WatchPendingTransactionsParameters<Transport>,
    ) => WatchPendingTransactionsReturnType

    Watches and returns pending transaction hashes.

    • Docs: https://viem.sh/docs/actions/public/watchPendingTransactions
    • JSON-RPC Methods:
      • When poll: true
        • Calls eth_newPendingTransactionFilter to initialize the filter.
        • Calls eth_getFilterChanges on a polling interval.
      • When poll: false & WebSocket Transport, uses a WebSocket subscription via eth_subscribe and the "newPendingTransactions" event.

    Remarks

    This Action will batch up all the pending transactions found within the pollingInterval, and invoke them via onTransactions.

    import { createPublicClient, http } from 'viem'
