Overview

Blockchain transactions are encrypted into hashes and it's not possible to simply understand for someone who doesn't know a lot about cryptography or blockchain technology that what's going on in that transaction. Noves Translate API is a powerful tool that helps you decode a transaction and make it easier to understand.

In this Function example, we will create a multi-chain transaction translator, using Noves Translate API.

Sample Function

The first step here would be to get a Noves API key.

Then Head over to the QuickNode Functions editor and paste the following code in it:

function main(params) {
    // Extract necessary information from params
    const vm = params.user_data.vm;
    const chain = params.user_data.chain;
    const txhash = params.user_data.txhash;
    const apiKey = params.user_data.apiKey;
    

    // Construct the URL
    const url = `https://translate.noves.fi/${vm}/${chain}/tx/${txhash}`;

    // Set up the options for the fetch request
    const options = {
        method: 'GET',
        headers: {
            'accept': 'application/json',
            'apiKey': apiKey
        }
    };

    // Perform the fetch request and return the data as-is
    return fetch(url, options)
        .then(response => {
            if (!response.ok) {
                throw new Error(`HTTP error! status: ${response.status}`);
            }
            return response.json();
        })
        .then(data => {
            // Simply return the data without any processing
            console.log(data);  // This will print the data in the QuickNode logs
            return data;
        })
        .catch(error => {
            console.error('Error:', error);
            return {
                error: error.message
            };
        });
}

In the above code we're getting few things like the vm (virtual machine), chain, transaction hash, and API key from user and sending request to the Noves API and printing the response along with some error handling.

Request

We will send our request with few parameters like vm (virtual machine), chain, transaction hash, and API key.

• vm can be evm for EVM (Ethereum Virtual Machine) blockchains, svm for SVM (Solana Virtual Machine) used by Solana, and cosmos for Cosmos blockchains.
• chain can be the following based on the virtual machine/ecosystem:
  • evm (arbitrum, arbitrum-nova, astar, avalanche, base, berachain-bartio, blast, bsc, camp-testnet, camp-testnet-v2, celo, chiliz, core, cronos, degen, eth, eth-holesky, eth-sepolia, ethxy-testnet, fantom, flow-evm, fraxtal, fuse, gnosis, kava-evm, lightlink, linea, lukso, manta-pacific, mantle, matchain, metis, moonbeam, moonriver, morph-holesky-testnet, morph-testnet, movement-mevm, optimism, orderly-network, plume-testnet, polygon, polygon-zkevm, pulsechain, rari, rollux, rollux-testnet, scroll, sophon-testnet, superposition-testnet, superseed-sepolia, taiko-katla, telos, xai, xdc, zetachain-evm, zetachain-evm-testnet, zksync-era, zora).
  • svm (solana).
  • cosmos (celestia, dymension).
• txhash will be your transaction hash for that particular chain.
• apiKey will be your Noves API Key.

We will invoke the function with the following cURL command. Be sure to also replace the YOUR_API_KEY with your own QuickNode API key and the POST URL with the URL of your Function along with the params mentioned above.

curl -X POST "https://api.quicknode.com/functions/rest/v1/functions/{functionId}/call?result_only=true" \
  -H "accept: application/json" \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "user_data": {
      "vm":"evm",
      "txhash":"0x1cd4d61b9750632da36980329c240a5d2d2219a8cb3daaaebfaed4ae7b4efa22",
      "apiKey":"NOVES_API_KEY",
      "chain":"eth"
    }
  }'
