Whether you’re building decentralized trading bots, DeFi apps, or smart contract platforms, accessing powerful off-chain data is key to creating intelligent and profitable on-chain systems.

That’s where the Token Metrics Crypto API comes in.

In this guide, we’ll walk you through how to integrate the Token Metrics API with Chainlink Functions, enabling you to deploy live smart contracts that interact with real-time crypto signals, token prices, and trader grades. You’ll learn how to use more than 20 API endpoints and smart contract adapters to power decentralized apps with actionable data.

If you’re searching for the best crypto API for smart contract development, or you need a free crypto API to start testing on testnets, this article is your ultimate resource.

What Is the Token Metrics Crypto API?

The Token Metrics API is an advanced data interface designed for traders, developers, and Web3 builders. It provides access to over 20 endpoints covering everything from:

  • Token prices
  • AI-powered trading signals (bullish/bearish)
  • Trader and Investor Grades (0–100 scoring system)
  • Quant metrics
  • Support and resistance levels
  • Sentiment analysis

Built by a team of quant analysts, machine learning engineers, and crypto-native researchers, the Token Metrics Crypto API brings hedge-fund-grade intelligence into the hands of everyday builders.

Why Use the Token Metrics API with Chainlink Functions?

Chainlink Functions enable smart contracts to securely retrieve off-chain data from any API. By integrating with the Token Metrics Crypto API, you can bridge institutional-grade analytics into fully decentralized apps—something not possible with basic or unreliable data sources.

Here’s why this combo is so powerful:

  • 🔗 Chainlink decentralizes your execution
  • 🧠 Token Metrics powers your logic with predictive analytics
  • ⚙️ Smart contracts can now act on real market intelligence

This integration enables the creation of intelligent trading bots, dynamic token allocations, and governance proposals backed by hard data—not speculation.

Step-by-Step: How to Integrate Token Metrics API with Chainlink Functions

Let’s walk through how to connect the best crypto API—Token Metrics—with Chainlink Functions to build and deploy a live smart contract.

1. Clone the GitHub Repo

Start by cloning the GitHub repository that contains the full codebase. This includes:

  • A set of ~20 pre-built smart contracts
  • API adapter logic
  • Sample scripts to interact with the contracts
  • A detailed README with setup instructions

Each smart contract is tailored to one Token Metrics API endpoint—meaning you can plug and play any dataset, from prices to sentiment scores.

2. Set Up Your Environment

The README provides a full list of recommended environment variables, including:

  • API_KEY for Token Metrics
  • LINK_TOKEN_ADDRESS
  • CHAINLINK_SUBSCRIPTION_ID
  • ORACLE_ADDRESS

Once your .env is ready, you can start compiling and deploying.

3. Build and Deploy a Sample Trading Bot Smart Contract

In this walkthrough, the developer built a Solidity smart contract that:

  • Pulls live data from Token Metrics (price, signal, grade)
  • Evaluates the signal (e.g., bullish)
  • Executes a buy trade if the signal is positive

The contract is compiled in Remix IDE, connected via MetaMask (on testnet), and deployed using testnet ETH and LINK tokens.

After deployment, you’ll receive a contract address that can be added to your Chainlink subscription.

4. Create a Chainlink Subscription

To fund your contract for data requests:

  1. Go to the Chainlink portal
  2. Create a new subscription (testnet or mainnet)
  3. Fund it with some LINK
  4. Add your deployed smart contract as a consumer

This allows your contract to make external data calls using Chainlink’s decentralized oracle network.

5. Run a Script to Invoke Real-Time Token Metrics Data

Using the provided JavaScript scripts, you can interact with the smart contract and test data flow:

  • Check the bot’s active status
  • Retrieve token price, trading signal, and grade
  • See how the smart contract responds to live market conditions

In the demo, the bot received a bullish signal, saw that the grade was high, and executed a buy trade accordingly. This logic can be expanded into full-scale trading strategies, rebalancing rules, or even on-chain governance triggers.

Why Token Metrics API Is the Best Crypto API for Smart Contracts

Here’s what makes the Token Metrics Crypto API the best crypto API for building advanced, data-driven dApps:

✅ Institutional-Grade Signals

Get access to proprietary AI trading signals, used by hedge funds and institutional desks.

✅ 20+ Endpoints for Every Use Case

Whether you need sentiment data, grades, price trends, or quant models, it’s all there.

✅ Real-Time and Back-Tested

The data is not just live—it’s tested. Token Metrics backtests every signal against market conditions.

✅ Easy to Integrate

Pre-built smart contract adapters make it easy to use the API in Chainlink, Remix, or any EVM-compatible environment.

✅ Free Crypto API Tier Available

Start testing on testnets with a free crypto API key. Upgrade later for full production access.

What Is an ETF in Crypto? A Complete Guide for Crypto Investors in 2025

Token Metrics Team
8 min
MIN

The world of crypto investing is expanding at lightning speed. With growing institutional adoption and mainstream interest, new financial instruments are emerging to make crypto more accessible to everyday investors. One of the most impactful of these tools is the Exchange-Traded Fund (ETF) — and in 2025, crypto ETFs are playing a crucial role in shaping the future of digital asset investing.

📊 What Is an ETF?

An ETF (Exchange-Traded Fund) is a type of investment fund traded on traditional stock exchanges, just like individual stocks. ETFs hold a basket of assets such as stocks, bonds, commodities—or, in this case, cryptocurrencies.

When you buy shares of an ETF, you’re investing in a diversified portfolio managed by an institution. Instead of buying each asset individually, ETFs let you gain exposure to a group of assets through a single security.

🪙 What Is a Crypto ETF?

A crypto ETF is a special type of ETF that tracks the price of one or more cryptocurrencies, such as Bitcoin, Ethereum, or a basket of altcoins. These ETFs allow investors to gain exposure to crypto markets without needing to buy, store, or manage digital assets directly.

Crypto ETFs are listed on traditional financial exchanges (like Nasdaq or NYSE) and can be purchased via brokerage accounts—making them ideal for both institutional investors and crypto-curious retail traders.

🔍 Types of Crypto ETFs

There are two main categories of crypto ETFs:

1. Spot Crypto ETFs

  • Directly hold the underlying cryptocurrency (e.g., Bitcoin, Ethereum).
  • Track the real-time price of the asset.
  • Considered the most accurate and direct method of gaining crypto exposure.
  • Example: BlackRock’s iShares Bitcoin Trust.

2. Futures-Based Crypto ETFs

  • Do not hold actual cryptocurrency.
  • Invest in futures contracts that speculate on the asset’s future price.
  • Prone to “tracking errors” and additional management fees.
  • Example: ProShares Bitcoin Strategy ETF (BITO).

In 2025, spot ETFs have become more popular, especially after multiple approvals in major markets like the U.S., Canada, and Hong Kong.

✅ Benefits of Crypto ETFs

Crypto ETFs offer a range of advantages for investors seeking exposure to digital assets without managing crypto wallets or private keys.

1. Accessibility

  • Trade crypto exposure from a traditional brokerage account.
  • No need for crypto exchanges, wallets, or DeFi protocols.

2. Regulation and Security

  • Managed by licensed institutions and regulated by bodies like the SEC.
  • Custody solutions are handled by professionals (e.g., Coinbase Custody, Fidelity Digital).

3. Diversification

  • Some ETFs offer exposure to a basket of cryptocurrencies, reducing risk.
  • Others may focus on specific sectors like DeFi or metaverse tokens.

4. Tax and Retirement Account Eligibility

  • Can be included in IRAs, 401(k)s, and tax-advantaged portfolios in some jurisdictions.

⚠️ Risks of Crypto ETFs

While crypto ETFs simplify access, they are not risk-free.

1. Management Fees

  • ETFs charge annual fees (0.20%–1.00%), which can affect long-term gains.

2. Lack of Full Ownership

  • You don’t hold the actual coins, so you can’t use them for staking, yield farming, or DeFi.

3. Volatility

  • Crypto markets are still highly volatile. ETF prices can fluctuate rapidly.

4. Tracking Errors (Futures ETFs)

  • Futures-based ETFs often lag behind the spot price of the cryptocurrency.

💡 Why Crypto ETFs Matter in 2025

The launch and adoption of crypto ETFs signal mainstream validation of the crypto market.

  • Over $60 billion has poured into Bitcoin and Ethereum ETFs since early 2024.
  • Institutional players like BlackRock, Fidelity, and ARK Invest are leading issuers.
  • Spot Bitcoin ETFs helped propel BTC above $118,000 in July 2025.
  • Regulatory green lights from the SEC, MAS, and other regulators mark a shift in global crypto policy.

Crypto ETFs reduce barriers to entry and give traditional investors a safe, regulated way to participate in the digital economy.

What Is ETF Trading? A Beginner’s Guide to Exchange-Traded Funds in 2025

Token Metrics Team
8 min

In today’s fast-paced financial markets, ETF trading has become one of the most popular and accessible investment strategies. Whether you're a traditional investor or a crypto enthusiast, understanding how ETF trading works can help you make smarter, more diversified investment decisions.

📈 What Is an ETF?

An ETF (Exchange-Traded Fund) is an investment fund that trades on stock exchanges, similar to individual stocks. Each ETF holds a collection of assets, such as:

  • Stocks (like the S&P 500)
  • Bonds
  • Commodities (like gold or oil)
  • Currencies
  • Cryptocurrencies (Bitcoin, Ethereum, etc.)

When you buy a share of an ETF, you're buying a fractional interest in the entire basket of assets. This makes ETFs a powerful tool for diversification, even for beginners.

💹 What Is ETF Trading?

ETF trading refers to the buying and selling of ETF shares on an exchange—just like you would with Apple or Tesla stock. The value of an ETF changes throughout the trading day, based on the underlying value of its assets.

ETF trading is commonly used for:

  • Portfolio diversification
  • Hedging strategies
  • Thematic investing (e.g., AI, clean energy, DeFi)
  • Speculating on short-term price movements

You can trade ETFs via your online brokerage, investment app, or even through certain retirement accounts (like IRAs).

🔄 How Does ETF Trading Work?

Here’s a simplified version of how ETF trading works:

  1. ETF Provider Creates the Fund
    A company like BlackRock or Fidelity creates an ETF that holds a specific basket of assets.

  2. ETF Listed on an Exchange
    The ETF is listed on public stock exchanges such as the NYSE or Nasdaq.

  3. Investors Buy and Sell Shares
    Investors trade ETF shares just like stocks—prices fluctuate throughout the day.

  4. Market Makers Maintain Liquidity
    Authorized participants ensure ETF prices closely match the value of the underlying assets (called the Net Asset Value or NAV).

🪙 What About Crypto ETFs?

In 2025, crypto ETFs have emerged as one of the fastest-growing segments of the ETF market.

Crypto ETFs allow investors to gain exposure to cryptocurrencies without owning the actual coins. These ETFs are regulated, secure, and accessible through traditional finance platforms.

There are two types:

  • Spot Crypto ETFs (hold actual crypto assets like Bitcoin or Ethereum)
  • Futures Crypto ETFs (track the price of crypto futures contracts)

Example: BlackRock’s iShares Bitcoin Trust (IBIT) is a spot Bitcoin ETF with billions in assets under management (AUM) in 2025.

✅ Benefits of ETF Trading

ETF trading offers unique advantages for both retail and institutional investors:

1. Diversification

Instead of buying dozens of individual stocks, ETFs offer broad exposure to sectors, themes, or markets in a single trade.

2. Liquidity

ETFs trade like stocks—buy or sell at any time during market hours. This makes them more flexible than traditional mutual funds.

3. Cost Efficiency

Many ETFs have low expense ratios, often under 0.25%. You avoid the high fees associated with actively managed funds.

4. Accessibility

Trade ETFs using any brokerage account. You don’t need to be an accredited investor or a crypto expert.

5. Tax Advantages

ETFs are generally more tax-efficient than mutual funds due to the in-kind creation/redemption process.

⚠️ Risks of ETF Trading

ETF trading, like all investing, carries risks:

1. Market Risk

ETF prices can go up or down depending on market conditions.

2. Liquidity Risk

Not all ETFs are highly traded. Low volume can lead to wide bid/ask spreads and slippage.

3. Tracking Error

Some ETFs fail to perfectly mirror their benchmark, especially futures-based crypto ETFs.

4. Sector Risk

Thematic ETFs (e.g., blockchain, AI) can be highly concentrated and volatile.

The cryptocurrency world continues to evolve rapidly, and one of the most significant milestones in recent years has been the approval and rise of Bitcoin ETFs. If you’ve ever wondered, “What is a Bitcoin ETF and why is it important?” — this guide breaks it down in simple terms.

In this highly informative blog, we’ll explore:

  • What a Bitcoin ETF is
  • Types of Bitcoin ETFs
  • Benefits and risks
  • Why Bitcoin ETFs matter for crypto adoption
  • How to analyze Bitcoin ETFs using Token Metrics tools

📈 What Is a Bitcoin ETF?

A Bitcoin ETF (Exchange-Traded Fund) is a financial product that allows investors to gain exposure to the price movements of Bitcoin without having to own or manage actual Bitcoin.

Just like buying a stock, investors can purchase shares of a Bitcoin ETF through traditional brokerage accounts. These shares represent ownership in a fund that tracks the price of Bitcoin.

In essence, a Bitcoin ETF bridges the gap between traditional finance and crypto investing.

🔄 How Does a Bitcoin ETF Work?

Bitcoin ETFs are created and managed by large financial institutions or asset managers. These funds:

  1. Buy Bitcoin directly (in spot ETFs), or
  2. Invest in Bitcoin futures contracts (in futures ETFs)
  3. Issue ETF shares that track the price performance of Bitcoin

These shares are then listed on stock exchanges like the NYSE, Nasdaq, or CBOE, where they can be bought or sold just like regular stocks.

🔍 Types of Bitcoin ETFs

There are two main types of Bitcoin ETFs:

1. Spot Bitcoin ETFs

  • Hold actual Bitcoin in custody
  • Track the real-time market price of Bitcoin
  • Provide direct exposure to Bitcoin’s price
  • Approved in the U.S. starting in early 2024 (e.g., BlackRock’s iShares Bitcoin Trust)

2. Futures-Based Bitcoin ETFs

  • Track Bitcoin futures contracts (derivatives)
  • Do not hold actual Bitcoin
  • Subject to contango and tracking errors
  • Were the first type approved (e.g., ProShares BITO)

In 2025, spot ETFs are considered superior due to their more accurate and direct exposure.

✅ Benefits of Bitcoin ETFs

Bitcoin ETFs offer several key advantages:

1. Accessibility

Investors can buy Bitcoin exposure through traditional brokerage platforms like Fidelity, Schwab, or Robinhood—no need for crypto wallets or private keys.

2. Regulation and Security

ETFs are regulated by institutions like the SEC and are managed by trusted financial firms, offering greater transparency and investor protection.

3. Tax Efficiency

Buying and selling ETFs may provide more favorable tax treatment compared to transacting in physical Bitcoin directly.

4. Institutional Adoption

Bitcoin ETFs enable pension funds, hedge funds, and banks to legally and easily gain exposure to BTC. Inflows from these entities have driven billions into Bitcoin in 2024 and 2025.

⚠️ Risks of Bitcoin ETFs

Despite their benefits, Bitcoin ETFs come with a few risks:

1. Price Tracking Errors

Futures ETFs may deviate from Bitcoin’s spot price due to volatility and contract rollover costs.

2. Management Fees

ETF providers charge an annual fee (0.20%–1.00%), which can reduce long-term returns.

3. Lack of Custody Control

You don’t actually own Bitcoin when you hold an ETF—so you can’t transfer it or use it for DeFi or crypto payments.

4. Market Volatility

Bitcoin remains a highly volatile asset. ETF shares may still experience massive price swings.

🏛️ Why Bitcoin ETFs Matter in 2025

The approval and adoption of Bitcoin ETFs mark a turning point in mainstream crypto acceptance. Here’s why:

  • Over $60 billion has flowed into U.S.-listed Bitcoin ETFs since January 2024
  • Institutions like BlackRock, Fidelity, and ARK Invest now actively manage Bitcoin exposure
  • Bitcoin ETF holdings reduce circulating supply, contributing to BTC’s price surge past $118,000 in mid-2025
  • Countries outside the U.S., including Canada and Hong Kong, are expanding their Bitcoin ETF offerings
