Building crypto functionality can be challenging for many Web3 businesses due to inadequate coding skills or resources. But what if these businesses do not need to build or redesign such functionality and can instead use existing solutions?
This is what crypto widgets offer. They allow businesses to embed crypto functionality such as exchanges or payments, market data tracking, tickers, and portfolio views in their products. And since widgets directly integrate into a business’s app or website, they create a smooth, unified experience for users without redirecting them to another platform. All this happens while businesses can still modify colors and logos or set the widget up to match their design.
In this guide, we break down five of the best crypto widgets business teams can use to embed crypto functionality in their products. We evaluate them based on their asset coverage, customization model, and who they are best for.
Our evaluation finds ChangeNOW to be the best crypto exchange widget for integrating swap functionality into Web3 businesses. The widget combines broad asset coverage with over 1,500 cryptocurrencies available for exchange on more than 110 networks. Businesses can deploy it with minimal technical effort, customize it to match their products, and earn commission revenue from completed swaps.
The list of the best crypto widgets:
- ChangeNOW
- Swapzone
- CoinGecko

Overview: ChangeNOW Crypto Exchange Widget is a ready-made solution that allows businesses to put crypto swaps on their products in a couple of hours. This means users swap right where they are instead of getting routed elsewhere. In return, these businesses earn a commission on every transaction they facilitate, starting from 0.4% or higher, since there is an option to customize the commission based on specific assets/pairs. All this happens with a simple development setup that often does not require engineers.
Asset coverage: The ChangeNOW widget supports over 1,500 crypto assets, available for exchange on more than 110 networks and over 2M exchange pairs. New assets are constantly being added, so businesses always have access to the latest and most trending assets.
Customization: The widget offers several customization options to match brands’ designs. Businesses can set the widget to make it a classic rectangle or a landscape banner-style layout, set a default language or let users pick their own. They can also match the widget’s primary and background colors to their site’s design, and switch on a dark theme.
Best for: The exchange widget is suitable for small Web3 projects that already work with digital assets, including crypto news websites, exchanges, wallets, and other crypto-related services.
Swapzone
Overview: Swapzone Swap Widget is a feature that allows any website or application to embed swap options. Once embedded, users on these platforms can trade any asset from the entire Swapzone exchange crypto selection without leaving the platform. A key benefit of the swap widget is that it outputs data directly from the Swapzone aggregator to display the best price to users. Businesses embedding the widget earn a percentage of the service fee on every transaction made. The reward scheme is cumulative, meaning the higher the monthly volume, the greater the profits for businesses, with revenue-sharing rates ranging from 0.05% to 0.25% per swap across five commission tiers. Partners with higher volumes can also negotiate custom profit-sharing agreements.
Asset Coverage: The widget provides swap support for more than 1,000 crypto assets, including all those listed by Swapzone’s aggregator partners.
Customization: Businesses adding the Swapzone widget into their products can choose the theme they like, either dark or light, and the orientation, either horizontal or vertical. They can also choose their custom default tokens from various pairs available or whether they want Swapzone’s logo to be shown or not.
Best for: Crypto exchange comparison sites, portfolio trackers, and established Web3 platforms with steady swap volume.
CoinGecko
Overview: Unlike the first two providers, which offer swap widgets, the CoinGecko widget operates as a tool for displaying cryptocurrency market data. The widget is made up of several services termed the ‘widget library,’ which includes a coin ticker, coin price chart, coin converter, coin heatmap, coin list/market table, and a random coin widget. All these visualizers focus on data display pulled from CoinGecko’s own price/market data and include referral links and buttons that direct users to external trading platforms.
Asset Coverage: The widget supports tens of thousands of coins tracked by CoinGecko, though individual widgets only display selected assets.
Customization: Each CoinGecko widget has configurable width and height, theme (either dark or light), currency, locale, and (for some) number of coins shown.
Best For: Crypto media, blogs, and portfolio sites that want live price/market data display.
MoonPay
Overview: MoonPay widget is a fiat-to-crypto on/off-ramp. Its architecture allows websites or applications to embed both fiat-to-crypto purchases and crypto-to-fiat payouts directly into their interfaces. For a buy transaction, the user picks an asset and payment method, then completes the flow inside the widget itself. Businesses can integrate it as a fully hosted widget for fast deployment or use MoonPay’s headless SDK to build a custom UI. One requirement worth flagging is that every user must pass KYC and risk-management checks in line with applicable laws. Also, the widget is not available in every country, and some of its features are also restricted by region.
Asset Coverage: The widget supports 100+ cryptocurrencies across major chains and multiple fiat payment rails, including cards, Apple Pay, Google Pay, bank transfers, and several local payment methods. Availability depends on the region.
Customization: Businesses can customize the widget to feel like a native part of their site or application. This can be done by adjusting button and background colors, choosing which cryptocurrencies customers can buy or sell, setting their own fees, or adding their logo to the transaction emails sent to customers. The widget also allows businesses to pre-fill user information such as their wallet address, email, selected token, fiat currency, amounts, and preferred payment methods.
Best For: Wallets, exchanges, and Web3 apps that need users to fund their accounts with fiat or cryptocurrency.
CoinMarketCap
Overview: CoinMarketCap operates as a market data widget similar to CoinGecko. The widget lists support for three layout formats on its official tools page: a coin ticker, coin price marquee, and coin price blocks. The ticker displays coin prices and can include fields such as market capitalization or trading volume. The marquee format operates as a running ticker, while the coin price blocks are used to present assets in separate price panels. All these solutions pull their data from the CoinMarketCap core dataset.
Asset Coverage: All three CoinMarketCap widgets cover tens of thousands of tracked cryptocurrencies. However, the number and type of assets that appear depend on what businesses configure.
Customization: The widget allows site owners to select a visual format, such as a ticker, marquee, or price blocks, and configure the assets to display. Businesses can also choose which stats to surface (ticker/rank/market cap/volume) and the theme, either light or dark.
Best For: News sites, blogs, and portfolio trackers.
Conclusion
As the crypto user base grows, so does the pressure on businesses to build products that meet their needs. But as we have seen, businesses no longer need an in-house developer team to address the issue. Widgets let them add crypto functionality in hours. And in most cases, this happens while they earn revenue.
The providers we have discussed above offer a good list to choose from. If your business wants users to swap crypto without leaving your page, ChangeNOW and Swapzone are the strongest options. If you need users to buy crypto with fiat, MoonPay fits that role. And if you simply want to display live prices and market data, CoinGecko and CoinMarketCap provide that. The secret is to match the widget to the right use case, and it will actually deliver on what your users need.
