The explosive growth of crypto assets and decentralized protocols has fueled demand for accurate, real-time blockchain data. Whether you’re building an application, performing due diligence, or exploring on-chain analytics, knowing how to access transactions and wallet balances is crucial. But do crypto APIs actually provide this level of on-chain data—and how can you use it effectively?

What Are Crypto APIs and Why Are They Essential?

Crypto APIs (Application Programming Interfaces) are software gateways that let applications interact with blockchains and related services without managing full nodes or direct infrastructure. These APIs power wallets, portfolio trackers, analytics dashboards, and AI-driven research tools with everything from price feeds to in-depth blockchain data.

Why use a crypto API? Running your own blockchain node can be resource-intensive, requiring disk space, bandwidth, security practices, and ongoing maintenance. An API abstracts this complexity, providing developers and analysts with curated endpoints for questing data on-demand. This is particularly valuable for applications that need:

  • Up-to-date transaction histories
  • Current wallet balances across tokens and networks
  • Wallet activity details
  • Aggregated analytics, like smart money flows and DeFi positions

The Types of On-Chain Data Crypto APIs Provide

On-chain data refers to all the information stored directly on blockchain ledgers. Crypto APIs tap into different layers of this data, including:

  • Transaction Data: Hashes, timestamps, senders, receivers, transferred assets, gas fees, and contract interactions.
  • Wallet Balances: Query current holdings of native coins (like ETH or BTC) and tokens (such as ERC-20s), and sometimes even NFTs.
  • Historical Address Activity: Complete transactional history of wallets, letting you analyze behavioral trends or audit activity.
  • Smart Contract Events: Details about token transfers, liquidity provision, swaps, or governance votes.
  • Network/Protocol Stats: Blockchain metrics like block times, mining data, and node health, important for infrastructure and analytics teams.

Modern crypto APIs go beyond simple read-access, offering data enrichment features such as address labels, scam alerts, and portfolio reconstruction. This enables AI-driven tools and traders to make sense of raw blockchain transactions with greater ease.

How Do Crypto APIs Fetch and Deliver On-Chain Data?

The process of serving real-time, reliable on-chain data is complex. Here’s how reputable API providers typically operate:

  1. Node Infrastructure: Providers run full nodes for each supported blockchain, ingesting every new block.
  2. Data Indexing: Data is parsed, structured, and indexed for fast lookups—allowing APIs to serve requests instantly, even for complex queries.
  3. Aggregation & Enrichment: Some platforms aggregate data across multiple chains or enhance raw data with analytics, labels, or risk scores, helping to contextualize wallet activity.
  4. API Layer Exposure: RESTful or GraphQL endpoints expose this information for developers and researchers.

For example, querying for a wallet’s balance generally involves calling an endpoint such as /address/{wallet}/balances, which returns all supported tokens and quantities for that wallet, directly from on-chain sources. Transaction history requests retrieve confirmed transfers and contract activities, often with additional tags for clarity.

Key Use Cases for On-Chain Transaction and Balance Data

On-chain data accessed via crypto APIs has become foundational in several scenarios:

  • Tracking Portfolio Value: Automated tools instantly aggregate wallet balances and transaction histories across multiple addresses, networks, and asset types.
  • Due Diligence & Audit: On-chain data reveals the actual movement of funds, enabling independent scrutiny for compliance, proof-of-reserves, and forensic analysis.
  • Developing dApps & DeFi Services: Most wallets, swaps, and lending apps rely on APIs to provide balance updates, confirm transactions, and fetch historical activity.
  • On-Chain Analytics: Researchers and AI models monitor whale activity, wallet clustering, and token flows to identify ecosystem trends.
  • Risk Management: Platforms use API-provided on-chain labels to detect scam addresses, risky protocols, or suspicious transaction patterns.

In addition, many quantitative research teams and AI-driven crypto tools ingest on-chain data through APIs to fuel predictive models, market research, and smart contract insights.

Choosing a Crypto API Provider: Essential Parameters

With dozens of API solutions available, consider the following when selecting a crypto API for on-chain data:

  • Data Completeness: Ensure the API supports the networks and asset types you need (e.g., native coins, tokens, NFTs).
  • Latency & Reliability: Fast data delivery and high uptime are critical for real-time trading applications and research automation.
  • Rate Limits & Pricing: Be mindful of free tier restrictions versus your anticipated query volume.
  • Data Enrichment: Does the provider offer wallet labels, scam detection, or analytics layers?
  • Documentation & Support: Robust docs and support channels make integrations smoother and troubleshooting faster.

If you’re integrating advanced analytics or AI-driven insights, prioritize API providers that combine raw on-chain access with actionable, processed intelligence.

FAQs on Crypto APIs and On-Chain Data

Can I access wallet balances and transaction histories via crypto APIs?

Yes, leading crypto API providers typically offer endpoints to retrieve wallet balances (for both native cryptocurrencies and supported tokens) and to view transaction histories, directly sourced from underlying blockchain ledgers. This streamlines personal portfolio tracking, due diligence, and analytics development.

Are crypto API data outputs reliable and up-to-date?

Reputable API providers maintain robust blockchain node infrastructure and update their databases in real time or near-real time. However, reliability also depends on network congestion, API rate limits, and provider-specific infrastructure. Always review service status and latency commitments before integrating for mission-critical use cases.

Do all crypto APIs support on-chain data for NFTs and Layer-2 networks?

No, coverage varies between providers. Some APIs offer comprehensive data across layer-1 (e.g., Ethereum, Bitcoin) and select layer-2 chains, while others may focus on specific asset classes or blockchains. Likewise, NFT balance and transaction endpoints are only available with APIs that index non-fungible token contracts. Always confirm network and asset support with your chosen provider.

How can developers integrate crypto API on-chain data into their apps?

Most APIs provide REST or GraphQL endpoints that can be queried using common programming languages or HTTP tools. Comprehensive documentation and SDKs (where available) guide developers through authentication, request parameters, and data formatting, making it straightforward to embed wallet balances, transaction lists, or on-chain analytics into web, desktop, or mobile applications.

What are the main benefits of using an API over running a own node?

Using a crypto API saves significant time and resources. Infrastructure, sync issues, storage maintenance, and security are handled by the provider. APIs also enrich data, aggregate multi-chain information, and simplify compliance and access controls, which can be much more complex and costly to reproduce independently.

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.

What is XRP (Ripple) Crypto - A Comprehensive Guide

Token Metrics Team
7 minutes

‍Cryptocurrencies have quickly become an important part of the global financial system, allowing users to make secure, low-cost transactions without needing a bank or other financial institution. One of the most popular and well-known cryptocurrencies is XRP (Ripple), a digital asset designed specifically for payments, remittances, and other forms of financial transactions. 

In this beginner’s guide to XRP, we'll look at how this cryptocurrency works, its benefits, and how it differs from other digital assets. We'll also discuss the process for buying and selling XRP and some potential issues that users need to be aware of. Whether you're new to cryptocurrency or just looking to learn more about XRP, this guide should provide a comprehensive overview of this digital asset and its potential uses.

What Is XRP (Ripple)?

XRP/Ripple is a blockchain network and digital token created to facilitate low-cost, secure, and fast international payments. Unlike other cryptocurrencies, XRP was designed from the beginning to be used for these financial transactions instead of a more general purpose like Bitcoin, Ethereum, and Litecoin. 

XRP can transfer money across borders quickly and with extremely low fees, making it ideal for banks, payment providers, and other financial institutions. XRP can complete these transfers quickly due to its use of a consensus protocol that allows it to confirm transactions within just 4 seconds. 

The XRP token is used to pay network fees for these transfers and is also used by financial service providers as a source of liquidity for cross-border payments. However, the XRP token is not required to use the Ripple network.

Benefits of Using XRP

There are many benefits to using XRP, including:

  • Low fees
  • Fast transaction times
  • High scalability
  • A large network of liquidity providers. 

These benefits make it an ideal choice for banks and other financial institutions that need to process international payments quickly and cheaply. Individuals can also use XRP to make international transfers, but they'll need to purchase the asset before doing so. XRP has advantages over other cryptocurrencies, including Bitcoin, as it was designed specifically for financial transactions. ‍

"Ripple can process almost 1500 transactions per second, compared to Ethereum's 21 and Bitcoin's 7."

How does an XRP Transaction Work?

To send money from one person to another, the sender must create a transaction sent to the network and verify. This process also involves creating an "offer" where the sender specifies the amount of XRP and the network fee. Once completed, the sender's wallet submits the transaction to the network and the fee. 

The network then forwards the transaction to one of the XRP "liquidity providers," who will purchase the amount of XRP specified by the sender and release it to the receiver of the transaction. These liquidity providers hold large amounts of XRP and sell it to other users. After the transaction has been verified by the network and the fee paid, the receiver will receive the money in his or her account.

How to Buy and Sell XRP?

Anyone with access to internet can purchase XRP and store it in a digital wallet. However, some exchanges require users to undergo a verification process before they can begin trading. In addition, most exchanges charge a small trading fee for each transaction, which can add up if you buy and sell frequently. 

Once you've obtained XRP, you can store it in a digital wallet, allowing you to access it from anywhere and providing you with control over the private keys.

Various wallets are available for storing digital assets, including hardware and paper wallets.

Potential Issues with XRP

Like all cryptocurrencies, XRP has potential network risk and governance issues. The community has debated these issues since XRP was first created, but they still need to be resolved.

XRP has a large network of validators that are responsible for verifying transactions. However, the network is centralized, which means it is vulnerable to a single point of failure. If the validators decide to act maliciously, they may be able to prevent other transactions from being verified or even reverse transactions that have already been approved.

XRP vs. Other Cryptocurrencies

XRP is different from most other cryptocurrencies because it was created specifically for financial transactions. This means that Ripple can process almost 1500 transactions per second, compared to Ethereum's 21 and Bitcoin's 7. XRP differs from other digital assets because it is not mined like other cryptocurrencies.

XRP Price History Over The Years

Ripple's token, XRP, became available in 2013 when the company conducted its first fundraising round. Following this initial coin offering (ICO), the price of XRP remained relatively low for several years, with the coin's price dropping below $0.01 in 2016.

However, XRP saw a significant spike in value in 2017, increasing by more than 36,000%. Since then, the price has fluctuated, but it has remained relatively high, and at the time of writing, the price of XRP stands at just under $0.50.

XRP Mining

Unlike other cryptocurrencies, Ripple was not designed to be mined like Bitcoin and Ethereum. Ripple's creators created 100 billion XRP tokens at the start of the project and distributed them to investors.

However, new XRP tokens are added to the network every few months through a process known as "escrow," where the network creates enough tokens to provide liquidity to the global financial system.

XRP Wallets

Some of the best XRP wallets you can use to store your coins in include:

  • Ledger
  • Trezor
  • Coinbase
  • Binance
  • Kraken

Top Exchanges To Buy XRP

Now that you know what XRP is, you can simply create your account in any of the exchange platforms below, complete your KYC and instantly buy your XRP tokens.

  • Binance
  • Kraken
  • Huobi
  • Bitfinex
  • eToro

Is XRP a Good Investment?

Owing to the technical analysis of the XRP, it is expected to reach a minimum price of $0.54 and a maximum of $0.64. Hence, the average trading price at $0.56. Experts believe that this crypto asset has great potential in terms of growing in value.

Having said that, it is always suggested for you to do your own research before arriving at a decision.

The Future of XRP

Ripple aims to create a global network of financial institutions and payment providers that use XRP for cross-border payments. If this vision is achieved, Ripple's cryptocurrency could become one of the world's most widely used digital assets, with billons of dollars flowing through the network daily.

There are some challenges that Ripple will have to overcome to achieve this goal. For example, Ripple needs to expand its network to include more financial institutions while convincing them to use XRP instead of their existing payment networks. 

The Bottom Line

Ripple has streamlined the process of global payment network while providing a useful service for existing financial institutions. Although there is also uncertainty about whether the XRP token should remain centralized or if it should be decentralized, it is one of the coins to keep an eye on.
