* Example if you use viem

```
const params = {
	account: walletClient.account.address,
	to: props.to,
	data: props.data,
	value: props.value ? BigInt(props.value) : undefined,
} as const

const gas = await publicClient.estimateGas(params)

const hash = await walletClient.sendTransaction({
	gas: gas,
	chain: VIEM_CHAINS[props.chainId],
	...params,
})
```
