CrossFi API FAQ

Frequently Asked Questions about the CrossFi API

What is CrossFi?

CrossFi is a blockchain platform designed to enable cross-chain interoperability and decentralized finance (DeFi) solutions. It provides a robust infrastructure for transferring assets between multiple blockchain networks, making it ideal for developers building decentralized applications (dApps) that require seamless cross-chain functionality.

What is the CrossFi API?

The CrossFi API allows developers to interact with the CrossFi network through a set of JSON-RPC methods. It supports operations such as asset transfers across chains, smart contract deployment, and data retrieval, empowering developers to integrate cross-chain functionality into their applications.

How can I get started using the CrossFi API?

For a step-by-step guide, check out the CrossFi API Quickstart.

Is CrossFi EVM compatible?

Yes, CrossFi is EVM-compatible, allowing developers to deploy Ethereum-based smart contracts and applications on its network, while also supporting interoperability with other blockchain ecosystems.

What API does CrossFi use?

CrossFi utilizes the JSON-RPC API standard, enabling efficient blockchain interactions. It provides a consistent and secure interface for cross-chain transactions and other decentralized operations.

What is a CrossFi API key?

When accessing the CrossFi network via a service provider like Alchemy, developers need an API key to send transactions and retrieve data. An API key allows for secure and authenticated access to the network.

Which libraries support CrossFi?

CrossFi supports popular Ethereum-based libraries like Web3.js and Ethers.js, enabling developers to leverage existing tools for cross-chain and DeFi applications.

What programming languages work with CrossFi?

CrossFi supports Solidity for smart contract development due to its EVM compatibility. For off-chain interactions, developers typically use JavaScript, TypeScript, or other widely-used web development languages.

What does CrossFi use for gas?

CrossFi uses its native token, XFI, to pay for transaction fees, gas, and other network operations.

What methods does Alchemy support for the CrossFi API?

You can find the full list of methods supported by Alchemy for the CrossFi API on the CrossFi API Endpoints page.
