Pure stake API service in javascript

post by harish on Jul 12, 2021

I got error in this line

let params = await algodclient.getTransactionParams();
console.log(params);

This line returns [object object].

Below is the full code:

const algosdk = require('algosdk');

//Retrieve the token, server, and port values for your installation in the algod.net
//and algod.token files within the data directory or use a standup instance if available

//TestNet
const token = "your token";
const server = "http://your.server";
const port = 8080;

//Recover the account

var mnemonic = "awake used crawl list cruel harvest useful flag essay speed glad salmon camp sudden ride symptom test kind version together project inquiry diet abandon budget";

var recoveredAccount = algosdk.mnemonicToSecretKey(mnemonic);
console.log(recoveredAccount.addr);
//check to see if account is valid
var isValid = algosdk.isValidAddress(recoveredAccount.addr);
console.log("Is this a valid address: " + isValid);

//instantiate the algod wrapper
let algodclient = new algosdk.Algod(token, server, port);
//submit the transaction
(async() => {
    //Get the relevant params from the algod
    let params = await algodclient.getTransactionParams();
    console.log("here" + params);
    let endRound = params.lastRound + parseInt(1000);
    let fee = await algodclient.suggestedFee();

// create LogicSig object and sign with our secret key
    let program = new Uint8Array(Buffer.from("ASABICI=", "base64"));
    console.log("program " + program);
    let lsig = algosdk.makeLogicSig(program);
    lsig.sign(recoveredAccount.sk);

//create a transaction
    let txn = {
        "from": recoveredAccount.addr,
        "to": "SOEI4UA72A7ZL5P25GNISSVWW724YABSGZ7GHW5ERV4QKK2XSXLXGXPG5Y",
        "fee": params.fee,
        "amount": 200000,
        "firstRound": params.lastRound,
        "lastRound": endRound,
        "genesisID": params.genesisID,
        "genesisHash": params.genesishashb64
    };

// create logic signed transaction.
    let rawSignedTxn = algosdk.signLogicSigTransaction(txn, lsig);

//Submit the lsig signed transaction
    let tx = (await algodclient.sendRawTransaction(rawSignedTxn.blob));
    console.log("Transaction : " + tx.txId);

})().catch(e => {
    console.log(e);
});

What I have to change?

If you are using PureStake API, you need to use the code samples there:

https://developer.purestake.io/code-samples

The way the token is sent in PureStake API is slightly different.
