Meld A Cardano-based DeFi Gets 100M Staked Tokens

In only three days, Meld, a new decentralized financial system that emerged on the Cardano (ADA) blockchain, managed to stake 100 million of its native currency MELD.

Meld announced the milestone on Twitter, with the achievement contributing to the DeFi protocol’s goal of providing services for staking bitcoin as collateral for fiat loans.

According to Meld, it aims to reach the world’s unbanked, while depending on Cardano to target nations with a large crypto population.

Meld’s approach requires customers to deposit cryptocurrency that will be locked in the account before borrowing loans backed by Cardano based on the locked collateral.

In the case of Cardano, you do a soft link of the asset from your wallet to the stake pool. So you’re pledging or you’re voting with your tokens. Your tokens always stay or your coins always stay in your wallet, but they’re locked up and they can’t be used for anything else,

Ken Olling, CEO of Meld

Meld permitted token holders to commit over 620 million ADA, almost $1 billion, in order to create the groundwork for the system. As a result, the platform was able to raise $10 million through a private token sale as part of a fundraising round.

Meld also used the ISPO crowdfunding model, with the staking pool quickly filling up with 64 million ADA. Within five days, the ISPO had four additional pools opened that filled up with 133 million ADA.

Users will be open to choose between a six-month lock or 12 months with a 12 percent and a 15 percent annual percentage rate, respectively.

Meld has also worked with Tingo, an African mobile operator, to incorporate the app.
In addition, the DeFi protocol is collaborating with Polygon, Vent Finance, and ADAmatic to link the Polygon and Cardano blockchains.

Whales Seen Accumulating Cardano (ADA)

Despite the recent price movement for ADA, according to on-chain analytics firm IntoTheBlock, Cardano millionaire addresses are aggressively acquiring. After falling to $0.92 on Jan. 22, ADA has been trading sideways. ADA was trading at $1.06 at the time of publishing.

In just the first month of 2022, the amount owned by addresses with 1-10 million ADA has climbed by 40.65 percent, according to IntoTheBlock. These addresses now possess 24.87 percent of the circulating supply, which is at 33.57 billion ADA, according to the report.

Diverse levels of whales appear to be accumulating in ADA. Since mid-December 2021, the number of Cardano addresses having a balance of 10,000 to 1,000,000 ADA has surged by a whopping 15,000 percent. In late January, these group of investors increased their holdings by $53.6 million in tokens.

Major Firm BlackRock To Create It’s Own Blockchain ETF

According to a filing with the US Securities and Exchange Commission on Jan. 21, BlackRock Inc., the world’s largest asset management business, has applied for an exchange-traded fund (ETF) that focuses on blockchain technology.

The iShares Blockchain and Tech ETF invests in firms that are involved in the “creation, innovation, and application of blockchain and crypto technologies” in the United States and overseas, according to the company.

The NYSE FactSet Global Blockchain Technologies Index is followed by the fund.
According to BlackRock, up to 80% of the ETF assets will be invested in equities that are part of the index. The remaining funds would be used to invest in equity-based futures, options, and swap contracts. Furthermore, the fund will not invest in cryptocurrency, either directly or through crypto asset derivatives.

“Similar to shares of an index mutual fund, each share of the Fund represents an ownership interest in an underlying portfolio of securities and other instruments intended to track a market index,” according to the SEC filing.

Google Going Crypto

As the firm looks to provide a wider range of financial services, including cryptocurrencies, Google has hired veteran PayPal CEO Arnold Goldberg to manage its payments division.

Google’s action comes after years of debating whether or not to invest directly in the embryonic blockchain technology. Twitter’s investment in crypto infrastructure, as well as Facebook’s efforts into the metaverse, look to be catching up to the internet giant.

Also Google hired a new “Founding Leader” for blockchain project, Venkataraman.

According to his LinkedIn page, Venkataraman, who has worked for Google for more than 18 years, brings more than 25 years of experience as a software engineer with firms such as IBM, as well as more than 10 years in paid advertising for the internet giant, to the table.

Pavia Metaverse Project Debuts On Cardano (ADA)

The Metaverse is currently in its early stages. While Ethereum-based metaverse games like The Sandbox have exploded in popularity, investors are also interested in developing applications on secure PoS networks like Cardano. One of the distinctive triggers for ADA’s recent climb is its inclusion, which is interesting.

Pavia, a Cardano-based metaverse project, is identical to Decentraland but for one major difference: it is based on Proof-of-Stake (PoS).

Pavia’s admission into the Cardano ecosystem comes at a time when its own crypto-asset, ADA, has been under constant negative pressure as a result of the market-wide downturn.
However, the NFT activity on top of the network gave the token a much-needed boost, and it now trades at $1.55, up over 14 percent in the previous 24 hours.

Pavia, the Cardano blockchain’s freshly released gaming application, has huge aspirations for this year. At least 100,000 “land parcels” have been released so far, each of which is minted as a unique numbered Cardano NFT (CNFT) based on coordinates. In October and November of last year, more than 60% of the land lots were pre-sold. The remainder will be available in the current quarter.

Pavia has around 8,300 landowners, according to the official website. They cannot, however, visit or install any material into their separate land parcels at this time. The staff was working “to offer the in-game Pavia experience,” according to the website.

Pavia, like other metaverse projects, includes an in-game money called PAVIA that is utilized for usefulness inside the metaverse ecosystem.
After a blockchain snapshot in December 2021, Pavia NFT landholders received a 25% airdrop of this native coin.

Pavia has recently announced a partnership with readyplayer.me, a cross-game avatar platform for the metaverse, to allow users to create their own avatars that are interoperable with over 700 applications and games outside of the Pavia ecosystem.

Pavia plans to bring liquidity to Cardano decentralized exchanges [DEXs] and investigate cross-chain liquidity in the first quarter of 2022.

It also intends to investigate on-platform assets, gamification, and other topics. The project’s goals for the next quarter are to collect all comments and “start building for the in-game Pavia.io experience look and feel,” as well as to double down on interoperability, cross-chain, and cross metaverse. Pavia Plaza will host the first live event in the third and fourth quarters, and Pavia portal testing will commence.

New Fund For Algorand-Focused Products Launched By Borderless Capital

Borderless Capital has launched a $500 million fund investing in digital assets powering the next generation of decentralized applications on top of Algorand (ALGO). The Miami-based company started its first Alogorand-focused fund in June 2019. It initially raised $200 million and invested in more than 100 companies, including BlockDaemon, Six Clovers and Osprey Funds. “There is a huge room to grow from here,” David Garcia, Borderless Capital’s founding managing partner said. Borderless Capital has announced a new fund that will invest in the Algorand ecosystem specifically for products involving DeFi liquidity mining, yield farming, lending, borrowing and trading

The firm will be announcing specific investments of the new fund in the coming months. SkyBridge Capital and NAX revealed a partnership in September to offer decentralized applications and institutional investment opportunities that will be part of the initiative using Algorand.

Solidity Series – Building Your First Hello World

Knowing others is wisdom, knowing yourself is enlightenment.

— Lao Tzu.

It’s the start of decentralization age but how to start programming on decentralize environment?

Ethereum1, considered as second wave of blockchain innovation. The pioneer and first blockchain ecosystem to implement and handle smart contracts. So how do you start developing system and application DApps (Decentralize Apps) in it?

The answer is “Solidity” — a programming language that interface EVM (Ethereum Virtual Machine) and your app.

Prerequisites

In this tutorial we assume you have some basic knowledge in programming.

The main requirements in developing a blockchain app is first its compiler then the secondary requirements but optional are the bootstrap framework like truffle.

  • Node 10 and above

Building Hello World

To start the development, we must get the required dependency in developing a structured smart contract project. The tool and framework that we will be using is truffle, which handles all the bootstrapping procedure and creates the base of your project. Installing it is just breeze, all you have to do is type npm install -g truffle.

Also install ganache which is the old ethereum-test-rpc project. To install ganache you have an option whether to install it on a desktop or a CLI (Command Line Interface) build. For this project I’ll be using the CLI build, so to start we install ganache using the command npm install -g ganache-cli. Both truffle and ganache is under the truffle software development platform.

And now we start building the project, after all dependencies installed we need to create an empty project directory with the command truffle init. As a note, the init sub-command only works on an empty directory. This sub-command will create a base structure for our project.

Project Structure

Below is a structure that I recommend to bootstrap your project.

  • contracts: Storage of smart contracts source.
  • migrations: Migration script to deploy smart contract.
  • test: Test directory for smart contract.
  • truffle-config.js: Truffle configuration for Windows users (for backward compatibility).
  • truffle.js: Truffle configuration for *nix system.

To test if everything’s okay we must run truffle compile.

Running a test RPC for Ethereum

So in order to start, we first need to generate test accounts and run a test environment. Start by typing ganache-cli in a separate non-occupied terminal window. The tool ganache will generates 10 ETH addresses with an initial balance of 100 ether.

Coding your first hello

With ganache-cli running at background, we continue building our hello world project. To start, we must create a new contract using truffle create contract Hello on which this command will create a new file under contracts ⇒ Hello.sol. Edit the newly created file and add a new function that will return the string Hello in EVM.

pragma solidity ^0.4.24;

contract Hello {
	function greeter() public pure returns (string) {
		return "Hello World";
	}
}

In the next step, will be creating and editing the migration file. To create the file execute touch migrations/2_deploy_contracts.js, then edit the new file and link that to the file we created earlier Hello.sol. This is a very crucial step in order to deploy our Hello solidity file on test blockchain environment.

Here are the changes we need in migrations/2_deploy_contracts.js.

var hello = artifacts.require("./Hello.sol");
module.exports = function(deployer) {
	deployer.deploy(hello);
}

After we edit the migration file, we can now connect the truffle project to ganache test blockchain RPC environment. To do that we’ll be editing truffle.js and point it to ganache host and port which is localhost:8545.

module.exports = {
	networks: {
		development: {
			host: "localhost",
			port: 8545,
		},
	},
};

When everything’s done, execute truffle migrate. This command will automatically compile and deploy the smart contract into ganache test blockchain RPC environment. Remember and copy the Hello function address in the output console, we will be using this later.

To test the function if its already deployed in the test environment, we will execute a REPL console using truffle console. Then inside the console, we type Hello.at(address).greeter() (note the address here is the one we copy earlier).

If everything is correct it should output Hello World. That’s it, now you’re on your way to become a blockchain developer.This is the link to the whole source code.

Conclusion

Hey guys, now that you’ve finish the setup you are now on the path of becoming a blockchain software developer. Follow us on our next adventure developing deep into the blockchain ecosystem. Stay tuned for the next follow up series for solidity.
