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.

10 Best Crypto Trading Strategies for Traders in 2023

Marcus K
8 minutes
MIN

Crypto trading has emerged as a popular and lucrative form of investment over the past few years. As the crypto market continues to grow and evolve, more and more traders are turning to various strategies to help them navigate the market and increase their profits.

A successful crypto trading strategy requires a deep understanding of the market, technical analysis, risk management, and a willingness to adapt to changing market conditions.

In this post, we will explore the best crypto trading strategies to use in 2023.

Top 10 Crypto Trading Strategies

Let's explore some of the most popular crypto trading strategies, their advantages and disadvantages, and how to implement them effectively. Whether you're a seasoned trader or a beginner, understanding these strategies can help you make informed decisions and achieve your trading goals.

Here are the 10 crypto trading strategies that traders commonly use:

1. HODLing an asset

HODLing, as it is commonly known in the cryptocurrency world, refers to the practice of holding onto a cryptocurrency for the long term, rather than selling it for a short-term gain. The term originated in 2013 when a user on a Bitcoin forum misspelled the word "hold" as "hodl" in a post encouraging others to resist the temptation to sell during a price drop. HODL also commonly come to stand for "hold on for dear life" among crypto investors.

The basic idea behind HODLing is that cryptocurrencies are still in their early stages of development and have the potential for significant long-term growth. By holding onto a cryptocurrency for the long term, investors hope to benefit from its potential future value, rather than just its current market price.

However, HODLing does involve risks, as the cryptocurrency market is highly volatile and can experience significant price swings in a short amount of time. Therefore, it's important to conduct research and due diligence before deciding to HODL a particular cryptocurrency, and to have a solid understanding of the market trends and the underlying technology and fundamentals of the cryptocurrency in question.

2. Swing Trading Strategy

Swing trading consists of buying and holding a cryptocurrency for a short period of time, usually a few days or weeks, with the aim of profiting from price movements within that time frame. The goal is to capture short-term price swings or "swings" in the market.

Swing traders often use technical analysis to identify potential entry and exit points for their trades. They look for chart patterns, such as trend lines, support and resistance levels, and moving averages, to determine the direction of the market and the optimal time to buy or sell a cryptocurrency.

3. Scalping Trading Strategy

Crypto scalping is a trading strategy that involves making small, quick profits by buying and selling cryptocurrencies within a short time frame, usually a few minutes to an hour. Scalpers aim to profit from small price movements, taking advantage of short-term volatility in the market.

To be successful at crypto scalping, traders need to be able to quickly identify opportunities and act fast. They often use technical analysis to identify short-term trends and support and resistance levels to determine entry and exit points for their trades. Scalpers may also use trading bots or automated algorithms to execute their trades quickly and efficiently.

Furthermore, scalpers need to be disciplined and patient, as it can take time to identify profitable trades and execute them quickly.

4. Technical Analysis

Technical analysis is a trading strategy that involves studying historical market data, such as price charts and volume, to identify patterns and trends that can help predict future price movements of a cryptocurrency. It's based on the idea that past market behavior can help inform future market behavior.

In technical analysis, traders use various tools and indicators to analyze market data and make trading decisions. Some of the most commonly used indicators include moving averages, trend lines, support and resistance levels, and relative strength index (RSI). Traders may also use chart patterns, such as head and shoulders, triangles, and flags, to identify potential price movements.

Technical analysis can be useful in predicting short-term price movements of a cryptocurrency, but it does have limitations. It cannot account for unexpected events, such as regulatory changes, technological advancements, or other external factors that can affect the cryptocurrency market.

5. Fundamental Analysis

Fundamental analysis is a basic yet powerful trading strategy that promotes studying the underlying factors that influence the value of a cryptocurrency. These factors can include the technology and development of the cryptocurrency, the market demand for it, the regulatory environment, and other macroeconomic factors that can affect the cryptocurrency market.

In fundamental analysis, traders look at a cryptocurrency's fundamentals, such as its whitepaper, development team, partnerships, adoption rate, and market share, to determine its long-term value and potential for growth.

One of the key advantages of fundamental analysis is that it can provide insights into the long-term value and potential of a cryptocurrency, beyond just short-term price movements. It can also help traders identify undervalued or overvalued cryptocurrencies and make informed investment decisions based on their analysis.

6. Arbitrage Trading Strategy

Arbitrage is a trading strategy that involves taking advantage of price differences between different cryptocurrency exchanges or markets to make a profit. In the context of cryptocurrency, arbitrage involves buying a cryptocurrency on one exchange where it is priced lower and simultaneously selling it on another exchange where it is priced higher, thereby profiting from the price difference.

To successfully execute an arbitrage trade, traders need to be able to identify price discrepancies quickly and act fast. This often involves using trading bots or automated algorithms to scan multiple exchanges simultaneously and identify potential arbitrage opportunities.

7. News Based Trading Strategy

News-based trading is a trading strategy that involves using news events and announcements to make trading decisions. This strategy involves monitoring news sources, such as financial news outlets, social media, and official announcements, to identify events or news that could potentially impact the cryptocurrency market.

When a news event is announced, traders will analyze the information and try to predict how it will affect the price of a particular cryptocurrency. Based on their analysis, traders may enter or exit positions in anticipation of the market's reaction to the news.

News-based trading can be a profitable strategy if done correctly, as news events can have a significant impact on the cryptocurrency market.

For example, a positive announcement from a major company about adopting a cryptocurrency can lead to an increase in demand and drive up prices. Conversely, negative news such as a security breach or regulatory crackdown can lead to a decrease in demand and drive down prices.

8. Market Making Strategy

Market making is a trading strategy used by professional traders to provide liquidity to the market. In the context of cryptocurrency, market makers buy and sell cryptocurrencies with the goal of making a profit by buying at a lower price and selling at a higher price, while also providing liquidity to the market.

Market makers do this by placing limit orders on both sides of the order book, buying at a lower price and selling at a higher price than the current market price. By doing so, they provide liquidity to the market, ensuring that buyers and sellers can easily execute their trades without significant slippage.

Market making can be yielding profits as market makers earn a profit from the bid-ask spread, which is the difference between the highest price that a buyer is willing to pay for a cryptocurrency (the bid) and the lowest price that a seller is willing to sell for (the ask).

9. Position Trading Strategy

Position trading involves holding a position in a cryptocurrency for an extended period of time, typically weeks, months, or even years. Position traders aim to profit from long-term trends and market movements by taking a position in a cryptocurrency and holding it for an extended period, regardless of short-term fluctuations in price. 

Position traders typically use fundamental analysis to identify cryptocurrencies with strong long-term potential and then hold the position for an extended period of time, waiting for the market to move in their favor.

This strategy can be used to capture long-term trends and take advantage of long-term market movements, potentially resulting in significant profits. In addition to this, traders can monetize from reinvesting their profits to increase the size of the position. 

10. Algorithmic Trading Strategy

This is one analytical trading strategy that uses computer programs to execute trades based on pre-programmed instructions, also known as algorithms. In the context of cryptocurrency, algorithmic trading can be used to buy and sell cryptocurrencies based on market conditions, technical indicators, or other factors.

Algorithmic trading programs can be customized to suit a trader's specific needs and can be used to automate the trading process, allowing traders to execute trades more quickly and efficiently. These programs can analyze market data in real-time, making trading decisions based on predefined rules and criteria.

When done correctly, it can help traders to react quickly to changing market conditions and take advantage of short-term opportunities. Also, algorithmic trading programs can help to remove emotions from the trading process, allowing traders to stick to their trading plan and avoid making impulsive decisions.
