This question is related with the question below. <https://docs.alchemy.com/discuss/62fb458c95bee000365755ab> const netObj = { // name: 'polygon-amoy', name: 'maticamo', chainId: 80002 } const provider = new ethers.providers.AlchemyProvider(netObj, apiKey); Thanks Akira

We're trying to use Alchemy's Ethereum API service to retrieve Eth and ERC20 txn history and balances. We've noticed that when you send a large batch txn request, sometimes the request gets denied. What is the batch request limit for these transactions?

Hello, <br> As I try to send multiple transactions at the same time, some webhook messages of transactions are not delivered to my server. Can you check why I can't receive webhook messages for this case, please? Thanks,

Hi. we no longer use the service and I'd like to delete my Alchemy account and the associated team.

Hello, Could you provide pricing data in compute units for the following NFT API Calls? 1.Floor price 2. Sales volume per period for NFT 3. Owners per Collections/NFT Token

I was following the tutorial to build a DeFi app called "Buy Me a Coffee" (link: <https://docs.alchemy.com/docs/how-to-build-buy-me-a-coffee-defi-dapp>). However, I encountered some deprecated syntax, which caused me to get stuck at certain steps before deploying it to Ethereum Goerli testnet. I am currently trying to find the correct way to complete the dApp. 1. The command `npx hardhat` will be deprecated; please use `npx hardhat init` instead. 2. In the scripts/buy-coffee.js file, `await buyMeACoffee.deployed()` has been deprecated. Please use `await buyMeACoffee.waitForDeployment()` instead. 3. In the scripts/buy-coffee.js file, `buyMeACoffee.address` has been deprecated. Please use await `buyMeACoffee.getAddress()` instead. 4. In the scripts/buy-coffee.js file, the statement `hre.ethers.utils.formatEther(balanceBigInt)` encounters an error. To resolve this, use ethers directly by adding `const { ethers } = hre;` and then use `ethers.formatEther(balanceBigInt)`. Thank you for your attention.
