[SOLVED] How to transfer tokens from cloud function

Moralis General
#1

Is there a way to transfer tokens from Cloud Function?

A couple days ago, I implement the feature with Speedy Nodes. It was working perfectly.

But Moralis decided to remove Speedy Nodes. Itā€™s gone. (Actually Iā€™m still thinking that a bad decision)
After that, my code just returns ā€œSpeedy Nodes are discontinuedā€ error message.

I read a document that Moralis suggests using runContractFunction
But Itā€™s only possible for read public function. There is no way to set private key and transfer my tokens.

I need programatically transfer tokens from server side. Not manually form client side.

Do you have any ideas on this?

Even though Moralis though away Speedy Nodes, I still like Moralis.

It may have changed now but you can try using web3.js in a cloud function. Then you could set up a wallet using your private key and transfer tokens manually.

Speedy node URLs are easily replaced with an RPC URL from another provider like Chainstack which we recommend.

#3

Thank you for the reply!

I set up Chainstackā€™s Polygon Mumbai node. And put the url into Cloud Function like this.

  const web3 = new Moralis.Web3(
    new Moralis.Web3.providers.HttpProvider(
      "https://<username>:<password>@nd-058-264-835.p2pify.com"
    )
  );


.....
.....

  const signResp = await web3.eth.accounts.signTransaction(tx, private_key).then(async (signedTx) => {
    const sentTx = await web3.eth.sendSignedTransaction(signedTx.raw || signedTx.rawTransaction)
      .then(async receipt => {
        logger.info("Transaction code " + receipt.transactionHash);
        result = receipt.transactionHash
      })
      .catch(err => {
        logger.info('1: ' + err.message);
      });

But it always returns Transaction has been reverted by the EVM

Is my way of using Moralis.Web3.providers.HttpProvider wrong?
chainstack doesnā€™t have complicated setting. I guess something is wrong with my Cloud Function.

it could depend on the transaction that you made, what parameters you used

#5

I think nothing special. Actually this one was working with Moralis Speedy Nodes.

  const tx = {
    from: sender_address,
    to: contract_address,
    gas: 100000,
    data: contract.methods.bulksendToken(receiver_addresses, amounts).encodeABI()
  }

  const signResp = await web3.eth.accounts.signTransaction(tx, private_key).then(async (signedTx) => {
    const sentTx = await web3.eth.sendSignedTransaction(signedTx.raw || signedTx.rawTransaction)
      .then(async receipt => {
        logger.info("Transaction code " + receipt.transactionHash);
        result = receipt.transactionHash
      })
      .catch(err => {
        logger.info('1: ' + err.message);
      });
#6

if you try to use a public RPC url then it works? for example what you have in metamask

#7

The public RPC url is like this one?
"https://polygon-mumbai-rpc.gateway.pokt.network"

Itā€™s not working and the error message is all the same. Itā€™s ā€œTransaction has been reverted by the EVMā€

#8

is the transaction sent? do you see it in a blockchain?

#9

I think no. It cannot be seen on blockchain.
This is the full error message.

you can see the transaction here:
