/**
* Executes a write function on a contract.
*
* - Docs: https://viem.sh/docs/contract/writeContract
* - Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/contracts_writing-to-contracts
*
* 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](https://viem.sh/docs/glossary/terms) is needed to be broadcast in order to change the state.
*
* Internally, uses a [Wallet Client](https://viem.sh/docs/clients/wallet) to call the [`sendTransaction` action](https://viem.sh/docs/actions/wallet/sendTransaction) with [ABI-encoded `data`](https://viem.sh/docs/contract/encodeFunctionData).
*
* __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`](https://viem.sh/docs/contract/writeContract#usage) before you execute it.__
*
* @param client - Client to use
* @param parameters - {@link WriteContractParameters}
* @returns A [Transaction Hash](https://viem.sh/docs/glossary/terms#hash). {@link WriteContractReturnType}
*
* @example
* import { createWalletClient, custom, parseAbi } from 'viem'
* import { mainnet } from 'viem/chains'
* import { writeContract } from 'viem/contract'
*
* const client = createWalletClient({
* chain: mainnet,
* transport: custom(window.ethereum),
* })
* const hash = await writeContract(client, {
* address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
* abi: parseAbi(['function mint(uint32 tokenId) nonpayable']),
* functionName: 'mint',
* args: [69420],
* })
*
* @example
* // With Validation
* import { createWalletClient, http, parseAbi } from 'viem'
* import { mainnet } from 'viem/chains'
* import { simulateContract, writeContract } from 'viem/contract'
*
* const client = createWalletClient({
* chain: mainnet,
* transport: http(),
* })
* const { request } = await simulateContract(client, {
* address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
* abi: parseAbi(['function mint(uint32 tokenId) nonpayable']),
* functionName: 'mint',
* args: [69420],
* }
* const hash = await writeContract(client, request)
