      • (args): Promise<boolean>

      • Adds an EVM chain to the wallet.

        Parameters

        Returns Promise<boolean>

        Boolean indicating if the token was successfully added. WatchAssetReturnType

        Example

        import { createWalletClient, custom } from 'viem'
        import { mainnet } from 'viem/chains'

        const client = createWalletClient({

  • writeContract: (<const TAbi, TFunctionName, TChainOverride>(args) => Promise<`0x${string}`>)

    Executes a write function on a contract.

    A "write" function on a Solidity contract modifies the state of the blockchain. These types of functions require gas to be executed, and hence a Transaction is needed to be broadcast in order to change the state.

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

    Warning: The write internally sends a transaction – it does not validate if the contract write will succeed (the contract may throw an error). It is highly recommended to simulate the contract write with contract.simulate before you execute it.

    Param: args

    WriteContractParameters

    Returns

    A Transaction Hash. WriteContractReturnType

    Example

    import { createWalletClient, custom, parseAbi } from 'viem'
    import { mainnet } from 'viem/chains'

    const client = createWalletClient({
      chain: mainnet,
      transport: custom(window.ethereum),
    })
    const hash = await client.writeContract({
      address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
      abi: parseAbi(['function mint(uint32 tokenId) nonpayable']),
      functionName: 'mint',
      args: [69420],
    })

    Example

    // With Validation
    import { createWalletClient, custom, parseAbi } from 'viem'
    import { mainnet } from 'viem/chains'

    const client = createWalletClient({
      chain: mainnet,
      transport: custom(window.ethereum),
    })
    const { request } = await client.simulateContract({
      address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
      abi: parseAbi(['function mint(uint32 tokenId) nonpayable']),
      functionName: 'mint',
      args: [69420],
    }
    const hash = await client.writeContract(request)
