**getEnsAddress**

(`args`) => `Promise`<`GetEnsAddressReturnType`>

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](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `getEnsAddress`. You can use the built-in [`normalize`](https://viem.sh/docs/ens/utilities/normalize) function for this.

**Example**

```ts
import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'
import { normalize } from 'viem/ens'

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
})
const ensAddress = await client.getEnsAddress({
  name: normalize('wevm.eth'),
})
// '0xd2135CfB216b74109775236E36d4b433F1DF507B'
```

**getEnsAvatar**

(`args`) => `Promise`<`GetEnsAvatarReturnType`>

Gets the avatar of an ENS name.

* Docs: <https://viem.sh/docs/ens/actions/getEnsAvatar>

**Remarks**

Calls [`getEnsText`](https://viem.sh/docs/ens/actions/getEnsText) with `key` set to `'avatar'`.

Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS names](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `getEnsAddress`.

**Remarks**

Calls `reverse(bytes)` on ENS Universal Resolver Contract to "reverse resolve" the address to the primary ENS name.

**Example**

```ts
import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
})
const ensName = await client.getEnsName({

})
// 'wevm.eth'
```

**getEnsResolver**

(`args`) => `Promise`<`` `0x${string}` ``>

Gets resolver for ENS name.

* Docs: <https://viem.sh/docs/ens/actions/getEnsResolver>
* Examples: <https://stackblitz.com/github/wevm/viem/tree/main/examples/ens>

**Remarks**

Calls `findResolver(bytes)` on ENS Universal Resolver Contract to retrieve the resolver of an ENS name.

Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS names](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `getEnsAddress`.

* JSON-RPC Methods: [`eth_getFilterChanges`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getfilterchanges)

**Remarks**

A Filter can be created from the following actions:

* [`createBlockFilter`](https://viem.sh/docs/actions/public/createBlockFilter)

**readContract**

<`abi`, `functionName`, `args`>(`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](https://viem.sh/docs/clients/public) to call the [`call` action](https://viem.sh/docs/actions/public/call) with [ABI-encoded `data`](https://viem.sh/docs/contract/encodeFunctionData).

**Example**

```ts
import { createPublicClient, http, parseAbi } from 'viem'
import { mainnet } from 'viem/chains'
import { readContract } from 'viem/contract'

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
})
const result = await client.readContract({
  address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
  abi: parseAbi(['function balanceOf(address) view returns (uint256)']),
  functionName: 'balanceOf',
  args: ['0xA0Cf798816D4b9b9866b5330EEa46a18382f251e'],
})
// 424122n
```

  chain: mainnet,
  transport: http(),
})

Simulates/validates a contract interaction. This is useful for retrieving **return data** and **revert reasons** of contract write functions.

* Docs: <https://viem.sh/docs/contract/simulateContract>
* Examples: <https://stackblitz.com/github/wevm/viem/tree/main/examples/contracts\\_writing-to-contracts>

**Remarks**

This function does not require gas to execute and ***does not*** change the state of the blockchain. It is almost identical to [`readContract`](https://viem.sh/docs/contract/readContract), but also supports contract write functions.

Internally, uses a [Public Client](https://viem.sh/docs/clients/public) to call the [`call` action](https://viem.sh/docs/actions/public/call) with [ABI-encoded `data`](https://viem.sh/docs/contract/encodeFunctionData).

**Example**

```ts
import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
})
const result = await client.simulateContract({
  address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
  abi: parseAbi(['function mint(uint32) view returns (uint32)']),
  functionName: 'mint',
  args: ['69420'],
  account: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
})
```

**transport**

`TransportConfig`<`string`, `EIP1193RequestFn`> & `Record`<`string`, `any`>

The RPC transport

**type**

`string`

The type of client.

**uid**

`string`

A unique ID for the client.

**uninstallFilter**

(`args`) => `Promise`<`boolean`>

Destroys a Filter that was created from one of the following Actions:

* [`createBlockFilter`](https://viem.sh/docs/actions/public/createBlockFilter)
* [`createEventFilter`](https://viem.sh/docs/actions/public/createEventFilter)
* [`createPendingTransactionFilter`](https://viem.sh/docs/actions/public/createPendingTransactionFilter)
* Docs: <https://viem.sh/docs/actions/public/uninstallFilter>
* JSON-RPC Methods: [`eth_uninstallFilter`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_uninstallFilter)

**Example**

```ts
import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'
import { createPendingTransactionFilter, uninstallFilter } from 'viem/public'

const filter = await client.createPendingTransactionFilter()
const uninstalled = await client.uninstallFilter({ filter })
// true
```

**verifyHash**

(`args`) => `Promise`<`boolean`>

Verify that a hash was signed by the provided address.

* Docs <https://viem.sh/docs/actions/public/verifyHash>

**verifyMessage**

(`args`) => `Promise`<`boolean`>

Verify that a message was signed by the provided address.

Compatible with Smart Contract Accounts & Externally Owned Accounts via [ERC-6492](https://eips.ethereum.org/EIPS/eip-6492).

* Docs <https://viem.sh/docs/actions/public/verifyMessage>

**verifySiweMessage**

(`args`) => `Promise`<`boolean`>

Verifies [EIP-4361](https://eips.ethereum.org/EIPS/eip-4361) formatted message was signed.

Compatible with Smart Contract Accounts & Externally Owned Accounts via [ERC-6492](https://eips.ethereum.org/EIPS/eip-6492).

* Docs <https://viem.sh/docs/siwe/actions/verifySiweMessage>

**verifyTypedData**

(`args`) => `Promise`<`boolean`>

Verify that typed data was signed by the provided address.

* Docs <https://viem.sh/docs/actions/public/verifyTypedData>

**waitForTransactionReceipt**

(`args`) => `Promise`<`TransactionReceipt`>

Waits for the [Transaction](https://viem.sh/docs/glossary/terms#transaction) to be included on a [Block](https://viem.sh/docs/glossary/terms#block) (one confirmation), and then returns the [Transaction Receipt](https://viem.sh/docs/glossary/terms#transaction-receipt). If the Transaction reverts, then the action will throw an error.

* 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`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getTransactionReceipt) on each block until it has been processed.
  * If a Transaction has been replaced:
    * Calls [`eth_getBlockByNumber`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getblockbynumber) and extracts the transactions
    * Checks if one of the Transactions is a replacement
    * If so, calls [`eth_getTransactionReceipt`](https://ethereum.org/en/developers/docs/apis/json-rpc/#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**

```ts
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`) => `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`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_blocknumber) on a polling interval.
  * When `poll: false` & WebSocket Transport, uses a WebSocket subscription via [`eth_subscribe`](https://docs.alchemy.com/reference/eth-subscribe-polygon) and the `"newHeads"` event.

**Example**

```ts
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),
})
```

**watchBlocks**

<`includeTransactions`, `blockTag`>(`args`) => `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`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getBlockByNumber) on a polling interval.
  * When `poll: false` & WebSocket Transport, uses a WebSocket subscription via [`eth_subscribe`](https://docs.alchemy.com/reference/eth-subscribe-polygon) and the `"newHeads"` event.

**Example**

```ts
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),
})
```

**watchContractEvent**

<`abi`, `eventName`, `strict`>(`args`) => `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`](https://viem.sh/docs/contract/watchContractEvent#pollinginterval-optional), and invoke them via [`onLogs`](https://viem.sh/docs/contract/watchContractEvent#onLogs).

`watchContractEvent` will attempt to create an [Event Filter](https://viem.sh/docs/contract/createContractEventFilter) 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`](https://viem.sh/docs/actions/public/getLogs) instead.

**Example**

```ts
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**

<`abiEvent`, `abiEvents`, `strict`>(`args`) => `WatchEventReturnType`

Watches and returns emitted [Event Logs](https://viem.sh/docs/glossary/terms#event-log).

* Docs: <https://viem.sh/docs/actions/public/watchEvent>
* JSON-RPC Methods:
  * **RPC Provider supports `eth_newFilter`:**
    * Calls [`eth_newFilter`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_newfilter) to create a filter (called on initialize).
    * On a polling interval, it will call [`eth_getFilterChanges`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getfilterchanges).
  * **RPC Provider does not support `eth_newFilter`:**
    * Calls [`eth_getLogs`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getlogs) for each block between the polling interval.

**Remarks**

This Action will batch up all the Event Logs found within the [`pollingInterval`](https://viem.sh/docs/actions/public/watchEvent#pollinginterval-optional), and invoke them via [`onLogs`](https://viem.sh/docs/actions/public/watchEvent#onLogs).

`watchEvent` will attempt to create an [Event Filter](https://viem.sh/docs/actions/public/createEventFilter) 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`](https://viem.sh/docs/actions/public/getLogs) instead.

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
})
const unwatch = client.watchEvent({
  onLogs: (logs) => console.log(logs),
})
```

**watchPendingTransactions**

(`args`) => `WatchPendingTransactionsReturnType`

Watches and returns pending transaction hashes.

* Docs: <https://viem.sh/docs/actions/public/watchPendingTransactions>
* JSON-RPC Methods:
  * When `poll: true`
    * Calls [`eth_newPendingTransactionFilter`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_newpendingtransactionfilter) to initialize the filter.
    * Calls [`eth_getFilterChanges`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getFilterChanges) on a polling interval.
  * When `poll: false` & WebSocket Transport, uses a WebSocket subscription via [`eth_subscribe`](https://docs.alchemy.com/reference/eth-subscribe-polygon) and the `"newPendingTransactions"` event.

**Remarks**

This Action will batch up all the pending transactions found within the [`pollingInterval`](https://viem.sh/docs/actions/public/watchPendingTransactions#pollinginterval-optional), and invoke them via [`onTransactions`](https://viem.sh/docs/actions/public/watchPendingTransactions#ontransactions).
