About AnyAlt

AnyAlt is a CeDeFi platform offering a developer-friendly SDK that facilitates seamless cross-chain swaps and fiat-to-crypto transactions. It enables users to purchase any token, including low-cap altcoins, using fiat currencies across multiple networks, streamlining the onboarding process for Web3 applications.

CeDeFi cross-chain swaps

AnyAlt is an advanced developer infrastructure designed to streamline cross-chain execution and remove barriers between blockchain ecosystems. As users and assets become increasingly distributed across multiple networks, AnyAlt empowers Web3 applications to seamlessly bridge, swap, and interact with assets across chains—all with minimal code. The protocol combines powerful bridging logic, asset routing, and customizable last-mile execution, simplifying complex multi-chain operations for both developers and end-users.

At the heart of AnyAlt are two core components: the cross-chain swap engine and the last-mile transaction system. These features allow developers to not only move assets across chains but also trigger final smart contract actions—such as token purchases, NFT mints, or vault deposits—directly on the destination chain. With additional support for fiat on-ramps in over 190 countries, a modular SDK, and an open-source widget, AnyAlt enables Web3 teams to deliver a frictionless user experience while accessing deeper liquidity across 13 chains and 50+ protocols.

AnyAlt stands as a transformative cross-chain infrastructure solution built for Web3 protocols seeking to eliminate fragmentation between blockchain networks. With an emphasis on plug-and-play simplicity, it enables developers to embed full-stack cross-chain functionality into dApps without rebuilding token bridges or routing logic from scratch. Its unique combination of bridge aggregation, DEX aggregation, and fiat support allows protocols to connect users with any asset on any chain, using a single, integrated transaction flow.

A standout feature of AnyAlt is its support for last-mile transactions. Unlike basic bridges that stop at token transfer, AnyAlt allows developers to specify what should happen next—whether it's staking a token, calling a smart contract, or purchasing an NFT. This capability turns AnyAlt into a full-stack transaction engine that completes the user journey in one seamless experience. It also improves conversion rates by eliminating the need for users to visit external bridges or DEXs.

AnyAlt is designed for broad compatibility. It integrates easily with wallets from EVM-compatible chains, Solana, and even Bitcoin. The infrastructure includes a customizable, open-source widget and a powerful SDK for teams that prefer to build their own UI. Whether you’re building an IDO platform, an NFT marketplace, a GameFi app, or an AI investment agent, AnyAlt offers the modular tools to support complex user flows across ecosystems.

Security is also a critical focus. While AnyAlt does not operate its own bridge protocol—thus eliminating direct risk—it carefully curates the bridges it aggregates, requiring external audits and removing vulnerable integrations proactively. This design ensures that users and developers benefit from maximum flexibility without inheriting unnecessary risk. With support from ecosystem partners like Onramper and integrations across platforms like Aave, AnyAlt is becoming the invisible backend for the next generation of decentralized apps.

AnyAlt delivers a robust set of benefits and features that simplify cross-chain infrastructure and elevate user experience:

Bridge and DEX Aggregation: Connect to over 50 bridges and liquidity providers across 13 chains to enable cross-chain token swaps from any asset to any asset.
Last-Mile Transaction Execution: Automate project-specific actions after a swap, such as NFT purchases, token staking, or vault deposits—all in a single seamless flow.
Fiat On-Ramp Support: Accept payments in 190+ currencies using over 130 payment methods, reducing entry barriers for global users.
Customizable Widget: The AnyAlt widget provides a responsive UI that developers can integrate and brand within minutes.
Powerful SDK: Offers complete flexibility to build custom user interfaces while leveraging AnyAlt’s transaction engine.
Open-Source Architecture: All widget and SDK components are fully open-sourced, enabling endless customization and transparency.
Gas Refueling: Automatically supports native token refueling during swaps to ensure users can pay gas fees on destination chains.
Security via Curation: AnyAlt does not host its own protocol, avoiding direct exploit risk; instead, it only integrates audited, secure bridges.

AnyAlt makes it easy to implement cross-chain transaction infrastructure with either a widget or a developer SDK:

Step 1: Request an API Key
Visit the AnyAlt website and request your API key to begin your integration.
Step 2: Install the Widget
Use your preferred package manager to install the widget along with required dependencies: npm install @anyalt/widget @tanstack/react-query
Step 3: Wrap Your App in Providers
Set up QueryClientProvider and WidgetProvider using the default or a custom theme to enable widget functionality.
Step 4: Use the Widget
Add the AnyaltWidget component in your app, configure the swap and final tokens, and define transaction callbacks.
Step 5: Customize Your Experience
Leverage the open-source flexibility of the widget or use the AnyAlt SDK to build fully branded UIs with the same cross-chain power.
Step 6: Test Live
Try the live demos for token purchases and vault deposits to see how your flows can work in production.

AnyAlt FAQ

AnyAlt is a bridge aggregator rather than a bridge protocol, which means it doesn’t expose itself to the risks associated with direct bridge exploits; instead, it curates and integrates only audited, secure third-party bridges, and quickly disables any that report vulnerabilities to protect user transactions—learn more at AnyAlt.
Yes, with AnyAlt’s last-mile transaction feature, you can define a custom smart contract call—like staking, NFT minting, or token buying—that executes automatically after a successful cross-chain swap, providing a seamless end-to-end user experience through the AnyAlt widget or SDK.
If a security issue is detected in a supported bridge, AnyAlt acts immediately by pausing that integration, notifying affected users, and collaborating with the bridge provider to contain the risk, ensuring user safety without compromising other parts of the system—this makes AnyAlt a more resilient and secure solution.
Absolutely. With AnyAlt’s cross-chain swap + last-mile execution, you can let users purchase your token from any chain or token source, routing the transaction directly to your smart contract in one click—just configure your token address using the widget or SDK on AnyAlt.
Yes, the AnyAlt widget supports custom wallet setups and allows you to pass your own wallet connection to the interface, making it flexible for dApps with existing wallet management systems—perfect for projects that want full UX control without losing AnyAlt’s functionality.
