The evolving world of digital assets runs on data. For developers, analysts, and organizations navigating this landscape, harnessing accurate, timely, and actionable crypto data is fundamental to success. But how can you efficiently access vast ledgers, prices, and on-chain analytics from thousands of cryptocurrencies? Enter cryptocurrency APIs—the engines quietly fueling innovation and insight across the blockchain sector.

What Is a Cryptocurrency API?

An API (Application Programming Interface) is a standardized way for software to communicate and exchange information. A cryptocurrency API specifically facilitates seamless access to crypto-related data and functions. Whether dealing with historical prices, blockchain transactions, token metadata, or real-time market feeds, these APIs offer a programmatic gateway into complex digital asset ecosystems. Instead of manual research across multiple platforms, users can automate data collection, run analytics, or even build trading infrastructure—all with efficient, secure calls to an API endpoint.

The emergence of APIs has democratized access to blockchain data, benefiting projects of all sizes. Whether launching a DeFi dashboard, researching token analytics, or simply syncing exchange prices into spreadsheets, APIs are the backbone of digital asset research and development.

Types of Cryptocurrency APIs and Their Use Cases

Not all crypto APIs are created equal. Various categories reflect the diverse needs of the blockchain community:

  • Market Data APIs: Provide real-time and historical price feeds, trading volume, order books, and metadata for thousands of cryptocurrencies across exchanges. Use cases include price tracking apps, research dashboards, and price alerts.
  • Blockchain APIs: Serve raw blockchain data such as transaction histories, wallet balances, gas fees, and block explorers for networks like Bitcoin, Ethereum, and Solana. Essential for wallet apps, compliance tools, and NFT platforms.
  • Trading APIs: Enable users and bots to execute trades, manage orders, and monitor account activity directly on supported exchanges. Vital for algo-trading platforms, portfolio balancers, and market-making bots.
  • On-chain Analytics APIs: Provide deeper analytics, wallet clustering, smart contract activity, and DeFi/NFT insights to inform risk management, due diligence, or automated research.

The right API opens myriad doors—automating research, developing robust applications, and reducing manual overhead.

Key Features to Look for in a Cryptocurrency API

Choosing a crypto API isn’t just about the breadth of assets covered. Making a strategic selection involves assessing several core attributes:

  • Comprehensive Data Coverage: The API should offer support for major blockchains and tokens, with deep historical and real-time data.
  • Latency and Reliability: Low-latency data delivery is crucial for trading and analytics use cases. High uptime and robust SLAs are non-negotiable for mission-critical projects.

Ethereum Vs. Ethereum Classic: What's the Difference?

Token Metrics Team

MIN

Ethereum and Ethereum Classic are two of the most popular cryptocurrencies in the world today. Both of these digital currencies have exploded in value over the past few years and have become some of the most sought-after investments in the crypto market. 

But what is the key difference between ETH and ETC? 

Ethereum (ETH) and Ethereum Classic (ETC) are both blockchain networks, but they have a few key differences that make them unique. Ethereum is a newer platform that is designed to be more scalable and secure than Ethereum Classic. Ethereum Classic, on the other hand, is an open source blockchain network that has a focus on decentralization, immutability, and censorship resistance. In this article, we'll compare the two networks and explain why Ethereum is the better choice for most investors.

Overview of Ethereum and Ethereum Classic

Ethereum (ETH) is a decentralized blockchain network that runs smart contracts and enables the development of decentralized applications (dApps). Ethereum was created by Vitalik Buterin and officially released in 2015. 

Ethereum Classic (ETC) is an extension (not a clone) of the original Ethereum, which was forked away by the Ethereum Foundation by launching a new protocol just an year later in 2016. 

To be precise, Ethereum Classic was created when the original Ethereum network and currency were split following the DAO hack in 2016. Ethereum and Ethereum Classic are both open source networks that are maintained by their respective development teams. Unlike Bitcoin, both Ethereum and Ethereum Classic use a Proof-of-Work consensus algorithm. Both these networks also use a native digital token to fuel their networks. 

As Ether is the native token of the Ethereum network, you can use it to pay for transaction or computational services on the Ethereum network. Similarly, ETC tokens are used by participants on the Ethereum Classic network.

But, the majority of the crypto crowd still needs a clean chit over the key differences that make them absolutely distinct. 

So, let’s get into it.

Differences between Ethereum and Ethereum Classic

Scalability - Ethereum (ETH) and Ethereum Classic (ETC) are both open-source blockchain networks that allow you to build decentralized applications. However, Ethereum has been designed to be more scalable. That means the network can handle more transactions at a higher speed, making it a better choice for everyday applications. 

Security - While both Ethereum and Ethereum Classic are secure blockchain networks, Ethereum is more scalable and has a better security track record. Ethereum Classic has been dealing with network security issues since its inception. 

Decentralization - Decentralization is one of the core values offered by blockchain networks like Ethereum and Ethereum Classic. Decentralization on the Ethereum network is slightly better than Ethereum Classic, but both networks have a long way to go before they can be considered decentralized. 

Immutability - Immutability is another core value offered by blockchain networks. However, the Ethereum and Ethereum Classic networks are still very far from achieving full immutability. Both networks have suffered from various instances of data manipulation. 

Censorship resistance - Censorship resistance is another core value offered by blockchain networks. However, both Ethereum and Ethereum Classic are far from achieving full censorship resistance. Both networks can be subjected to censorship by governments and other centralized entities. 

ETH vs ETC - Which is the Better Choice for Investors?

While both Ethereum and Ethereum Classic are great investments, we believe Ethereum is the better choice for most investors for a few reasons. First, Ethereum is more decentralized. Second, Ethereum has been around longer than Ethereum Classic. This means the network is more scalable, secure, and well-established than its competitor. Finally, Ethereum has a wider range of applications than Ethereum Classic.

Overall, Ethereum is the better blockchain network when compared to Ethereum Classic.

The Bottom Line

Ethereum and Ethereum Classic, both of these networks have exploded in value over the past few years and have become some of the most sought-after investments in the crypto market.

When the DAO got hacked and lost $50 million, Ethereum needed a solid technology to replace the old one. So, a hard fork was done. But many traditional supporters of Ethereum did not want to go with the hard fork, and they stayed with the old blockchain technology. As a result, Ethereum Classic was born.

In this guide, we will answer what crypto yield farming is and how to do it.

Yield farming is a revolutionary way of earning passive income through cryptocurrency investments. It is a relatively new concept and has gained much attention in the crypto world. Yield farming involves using your cryptocurrency assets and taking advantage of lending platforms, decentralized finance protocols, and staking pools to generate incentives for interest payments, rewards, and capital gains. 

In this descriptive guide to crypto yield farming, you'll learn about the different types of yield farming, the rewards available, and the associated risks. You can earn passive income through yield farming with the right strategies and knowledge. So, let's dive right in and learn about crypto yield farming.

What is Crypto Yield Farming?

Yield farming is a process of using your cryptocurrency assets to generate incentives in the form of:

  • Interest payments, 
  • Rewards, and 
  • Capital gains. 

In other words, it is a form of passive income from cryptocurrency assets. Yield farming can also be considered a strategic investment strategy that allows you to earn income from your idle assets by lending them to other users. This process is similar to how people earn income from their savings accounts. 

These idle assets that you can stake can be your:

  • Computer's processing power
  • A certain amount of coins from your portfolio, or 
  • A certain amount of tokens from your portfolio. 

But how is this beneficial to you? 

Benefits of Yield Farming

Yield farming offers a wide range of benefits for both individuals and businesses. 

  • For individuals, yield farming can be a great way to earn extra income. It can help you diversify your crypto portfolio and hedge against some of the risks associated with investing in cryptocurrencies by generating extra income from your idle assets. This is why they call it an excellent way to earn passive income, which is one of the core benefits of cryptocurrency. 
  • For businesses, yield farming can help you expand your customer base and increase revenue. You can earn income by lending your idle assets while helping people earn interest and build their crypto portfolios. Although yield farming was once primarily used by mining operations, it can now be done by individuals, organizations, and other entities that are involved with cryptocurrency.

How Does Yield Farming Work in Real-time?

So, what do you need to do to get started with yield farming?

To begin with, the yield farmers will need to deposit their coins or tokens into decentralized applications or dApps of their choice for the following: 

  • Crypto trading 
  • Lending, or 
  • Borrowing. 

A few examples of dApps include crypto wallets, DEXs, decentralized social media, and more. Since these investors enhance the liquidity in their chosen dApp, they're referred to as liquidity providers. The crypto that yields farmers' deposits into DeFi protocols gets locked into autonomous smart contracts.

Types of Yield Farming

There are three types of yield farming - lending, providing liquidity, and staking. 

Lending refers to lending your idle cryptocurrency assets to earn interest payments. You are generating revenue through interest payments when you lend your cryptocurrency assets. This process is similar to how people earn interest from their savings accounts. 

Providing liquidity to decentralized apps for traders to trade on can also generate you fees. However, keep in mind that there exists impermanent loss in the process.

Staking refers to lending your coins to earn rewards through coins and staking fees. You are generating revenue through rewards and staking fees when you stake your coins. Rewards can come in the form of coins, tokens, or other types of digital assets. You are lending your coins to earn rewards.

Types of Rewards Available

Rewards are the incentives earned when you lend idle coins and cryptocurrencies to earn interest payments and generate passive income. There are many different rewards available to those who participate in yield farming. Some include interest payments, votes, staking rewards, and airdrops. 

Interest payments: This is the primary reward generated by yield farming. Interest payments are generated when you lend idle coins and cryptocurrencies to other participants. 

Votes: This refers to the ability to vote on certain network issues. 

Staking rewards are rewards generated by staking crypto assets for a certain period. 

Airdrops: This refers to the free crypto coins and tokens resulting from participating in a certain network or blockchain project.

Is Yield Farming Safe and Profitable?

Now that you know the benefits of yield farming, it's also important to know the risks. This is because no investment is risk-free, and the same is true for yield farming. When you decide to earn income from yield farming, you must consider the risks associated with it. Some risks associated with yield farming include network, liquidity, counterparty, and regulatory risks. 

Network risk refers to the risk associated with the security of the network/blockchain and its ability to function as expected. 

Liquidity risk is associated with the ability to liquidate your assets when you need them. 

Counterparty risk refers to the risk associated with the ability of the person/entity with whom you have the contract to fulfill the obligations. 

Regulatory risk is the risk associated with the ability of the government to enact new laws that can affect your earnings.

Smart contract risk is the risk associated with the probability of smart contracts getting hacked due to a bug or backdoor.

That said, there are definitely risks involved that you need to be aware of.

Strategies for Yield Farming

There are many strategies you can use for yield farming. Some of them include lending your idle assets to earn interest payments, staking your coins to earn rewards, and using different DAFs to generate passive income.

Lending your idle assets: This is one of the most common ways to earn income through yield farming. You can use your idle assets, such as your computer's processing power, to lend them to others who need them. 

Staking your coins: This is another popular way to generate passive income through yield farming. You can lend your coins to earn rewards. 

Using different DAFs: This refers to the use of decentralized autonomous funds that can generate passive income.

What's Next for Yield Farming?

Yield farming is a dynamic space that tends to change quickly; it often requires vigilance and time for farmers to cull out the best possible strategies. However, for someone who can manage it, yield farming will be highly profitable in 2023, even in the bearish market.  

That said, yield farming is significantly risky with rug pulls, hacks, impermanent loss, etc.

So, choosing your battle is important before getting into the ring. 

Platforms for Yield Farming

Many different types of yield farming platforms are available for you to use.

You can use these platforms to take advantage of your idle assets to generate income through interest payments and rewards.

Some popular yield farming platforms include Yearn Finance, Lido, and Liquity.

The Bottom Line

Yield farming is a revolutionary way of earning passive income through cryptocurrency investments. It involves using your cryptocurrency assets to take advantage of lending platforms, decentralized finance protocols, and staking pools to generate incentives in interest payments, rewards, and capital gains. While lucrative, it can be a riskier investment depending on the platform you go for and the type of yield you are generating.
