Simulate contracts to get error messages before user tries it
const { data, error, status } = useSimulateContract({
abi: BookingFactoryABI,
address: process.env.NEXT_PUBLIC_BOOKING_FACTORY_ADDRESS as any,
functionName: 'createBooking',
args: [1n, 'simulate'],
})
Estimate gas price for transaction to check if user has enough balance
useEffect(() => {
const a = async () => {
if (publicClient) {
const a = await estimateContractGas(publicClient, {
abi: BookingFactoryABI,
address: process.env.NEXT_PUBLIC_BOOKING_FACTORY_ADDRESS as any,
functionName: 'createBooking',
args: [1n, 'simulate'],
})
console.log(a, 'gasss')
}
}
a()
}, [publicClient])
Watch contract events to to retrieve write transaction reults
useEffect(() => {
if (publicClient) {
publicClient.watchContractEvent({
abi: BookingFactoryABI,
eventName: 'BookingCreated',
onLogs: (logs) => {
console.log(logs)
},
})
}
}, [publicClient])
Wait for transaction receipt after on success in writecontractasync to get events for that transaction
await writeContractAsync(
{
abi: BookingFactoryABI,
address: process.env.NEXT_PUBLIC_BOOKING_FACTORY_ADDRESS as any,
functionName: 'createBooking',
args: [influencersRequired, bookingId],
},
{
onError: (error) => {
setIsLoading(false)
},
onSuccess: async (hash) => {
if (publicClient) {
const receipt = await waitForTransactionReceipt(publicClient, {
hash,
})
const bookingIdInBytes = keccak256(toBytes(bookingId))
const log = receipt.logs.find((log) => log.topics[1] === bookingIdInBytes)
if (log) {
await axios.post('/api/booking/set-blockchain-address', {
booking_id: bookingId,
blockchain_address: log.topics[0],
})
// window.open('/dashboard/my-bookings', '_self')
}
}
setIsLoading(false)
},
},
)
