Alchemy Goerli Faucet
I see on the Alchemy faucet that I can receive 0.2 Goerli ETH daily if I am an Alchemy, active user. What is considered an active user by Alchemy so I can increase my daily test eth?

IPFS gateway timeout in NFT API for the alchemy SDK
I am trying to use the alchemy SDK to retrieve metadata for an NFT collection. I am using `getNftsForContract` function and receiving a response with all metadata missing. Here is an example response.
{
"contract": {
"address": "0x9A534628B4062E123cE7Ee2222ec20B86e16Ca8F"
},
"tokenId": "3",
"tokenType": "ERC721",
"title": "",
"description": "",
"timeLastUpdated": "2022-08-23T18:24:49.686Z",
"metadataError": "IPFS gateway timed out",
"rawMetadata": {
"metadata": [],
"attributes": []
},
"tokenUri": {
"raw": "https://ipfs.io/ipfs/Qmcob1MaPTXUZt5MztHEgsYhrf7R6G7wV8hpcweL8nEfgU/meka/3",
"gateway": "https://ipfs.io/ipfs/Qmcob1MaPTXUZt5MztHEgsYhrf7R6G7wV8hpcweL8nEfgU/meka/3"
},
"media": []
}
When I use the endpoint though, the meta is available. I'm not sure if it may be me or its the sdk. Any help?

How to format my balance from a hex number
Using alchemy.core.getBalance(address) I receive the balance in hex value. How do I convert this to something more human readable? I can't seem to find anything about it in the docs.

How can I get Optimism test ETH with Alchemy?
I am trying to test a contract on the Optimism Goerli network, but I can't find a faucet to get funds from. Does Alchemy have an Optimism faucet I can use?

Error: Returned error: insufficient funds for gas * price + value
Hello,
I've to return on an existing project i wrote 9 months ago... but now that I've switched to goerli testnet I got an error regarding the price...
I've done a getBalance and I've got '200000000000000000' wei balance (0.2ETH)
The error code occurs during the sign of the transaction
var nftContract = new web3.eth.Contract(contract.abi, blockChainAddress);
var gasEstimate =await nftContract.methods.mintNFT(publicKey, metadataUri).estimateGas();
var contractData = nftContract.methods.mintNFT(publicKey, metadataUri).encodeABI();
//the transaction
const tx = {
from: publicKey,
to: blockChainAddress,
nonce: nonceToUse,
gas: gasEstimate,
data: contractData
}
try {
var signPromise = await web3.eth.accounts.signTransaction(tx, privateKey);
await web3.eth.sendSignedTransaction(
signPromise.rawTransaction); ///<---- here
console.info("updating Token: " + token);
await updateMintInfomation(token, signPromise.transactionHash, nonceToUse, 'IN_PROGRESS', userToken);
await sleep(waitTimeout); //This is used to wait that the promise has been sent
console.info("The mint function has completed. Waiting for Blockchain response");
} catch (err) {
console.log(err);
throw err;
}
The estimateGasFee is 23400, what can I check please?
Thanks
