kandi X-RAY | eth-multisig-v4 Summary

eth-multisig-v4 is a JavaScript library typically used in Blockchain, Cryptocurrency, Ethereum, Bitcoin applications. eth-multisig-v4 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.
Multi-sig contract suitable for use as a 2-of-3 multisig wallet. The core functionality of the wallet is implemented in the WalletSimple contract. It is initialized with 3 signer addresses, two of which must participate in order to execute a transaction from the wallet. Auxillary contracts called Forwarders can be deployed with a WalletSimple contract initialized as its "parent". Any funds that the forwarder receives will be sent on back to the parent wallet. This enables omnibus-style wallets to create many addresses that are all controlled by the same wallet.

eth-multisig-v4 Key Features

Functions as a 2-of-3 multisig wallet for sending transactions.

Support for synchronous (single transaction) approvals containing multiple signatures through the use of ecrecover.

ERC20 tokens and ether can be sent out from the main wallet through a multisig process.

‘Safe Mode’ can be set on a wallet contract that prevents ETH and ERC20 tokens from being sent anywhere other than to wallet signers.

Transactions can be sent in batches through a batch function (sendMultiSigBatch) to save on fees if a user needs to perform multiple transactions.

Slightly different implementations exist for non-eth chains, which require signatures to include a networkId to protect against cross-chain replay of signatures.

Deployed with a single, permanent parent address.

Automatically flushes any ETH received to the parent address.

Able to flush ERC20 tokens received to the parent address through a separate transaction (flushForwarderTokens).

Wallets and forwarders are deployed as proxy instances to a single implementation, to save on deployment fees.

Wallets and forwarders are deployed using CREATE2 to allow addresses to be generated on demand, but only deployed upon first use.

Wallets include a batch function to save on fees when sending multiple transactions.

SequenceId is now simply a strictly increasing nonce.

QUESTION

Why on printing I get value of null from API call in Loop

Asked 2022-Apr-16 at 03:06

COIN LIST is an array of crypto coins(["BTCUSDT",...]). I try to get the price using getPriceAction and RSI from getRSI and these two functions are working when I try to console DATA. But when I try to print the response after the completion of the loop. It prints the empty array and the length is 0 of this array. I want to store the DATA object (consisting of SYMBOL, closing price and RSI) as an element in the response array

 import { COIN_LIST } from "./COIN_LIST.js";
    import { getPriceAction } from "./PRICE_ACTION.js";
    import { getRSI } from "./RSI.js";

async function main() {
  try {
    let response = await [];
    await COIN_LIST.forEach((element, i) => {
      setTimeout(() => {
        let data = { symbol: element };
        getPriceAction(element, "4h").then((res) => {
          data.closingPrice = res;
          getRSI(res).then((res) => {
            data.RSI = res.reverse();
            data.closingPrice = data.closingPrice.reverse();
            response.push(data);
            console.log(data)
          });
        });
      }, i * 1000);
    });
    console.log(response);
  } catch (error) {
    console.log(error.message);
  }
}
main();

After the completion of the loop, the promises didn't get resolved yet, that's why it print an empty array. One way to achieve what you need is using await for(...), or wait for all promises to be resolved, and then print the results.

import { COIN_LIST } from "./COIN_LIST.js";
import { getPriceAction } from "./PRICE_ACTION.js";
import { getRSI } from "./RSI.js";

async function main() {
  try {
    let response = []; //---> don't need that `await`
    const promises = []; //---> array of promises
    COIN_LIST.forEach((element, i) => {
      setTimeout(() => {
        let data = { symbol: element };
        const promise = getPriceAction(element, "4h").then((res) => {
          data.closingPrice = res;
          getRSI(res).then((res) => {
            data.RSI = res.reverse();
            data.closingPrice = data.closingPrice.reverse();
            response.push(data);
            console.log(data)
          });
        });
        promises.push(promise) //---> save the reference to a promise
      }, i * 1000);
    });
    await Promise.all(promises) //---> await for all promises to be resolved, then print the result
    console.log(response);
  } catch (error) {
    console.log(error.message);
  }
}
main();
