CrossFi Chain RPC for API connection of blockchain nodes for Web3 developmentConnect your Web3 app to CrossFi Chain (XFI) blockchain

What is CrossFi Chain (XFI) RPC?

CrossFi Chain (XFI) RPC is a communication protocol that allows sending remote procedure calls (RPC) to blockchain nodes using the CrossFi Chain network by Cross Finance. It enables developers to interact with the blockchain and perform actions such as sending transactions, querying information, and subscribing to events.

How can I use XFI RPC to connect to a blockchain node?

To connect to a blockchain node using XFI RPC, you will need to establish a connection to the blockchain node RPC endpoint. This can be done by providing the node's hostname or IP address, along with the appropriate port number and authentication credentials if required. Once connected, you can start making XFI, CrossFi Chain RPC calls to interact with the blockchain.

Which programming languages or libraries support CrossFi Chain (XFI) RPC?

CrossFi Chain (XFI) RPC is supported by various programming languages and libraries. Some popular options include Solidity language, Web3.js and Ether.js libraries. These libraries provide convenient interfaces to interact with the blockchain using CrossFi Chain RPC.

What are some common CrossFi Chain (XFI) RPC methods?

CrossFi Chain (XFI) RPC offers a range of methods to interact with the blockchain. Some common methods include eth_accounts to get a list of addresses owned by the client, eth_blockNumber to get the number of the most recent block, and eth_estimateGas to generate and return an estimate of how much gas is necessary to allow the transaction to complete. You can refer to the CrossFi Chain RPC documentation for a comprehensive list of available methods on CrossFi Chain nodes.

What is CrossFi Chain (XFI) API?

CrossFi Chain (XFI) API is an application programming interface (API) that allows developers to interact with the blockchain using the XFI CrossFi Chain network. It provides a set of endpoints, methods, and data structures that enable developers to retrieve blockchain information, send transactions, and build applications that leverage the blockchain's capabilities.

How can I access the XFI API?

To access XFI API, you need to make HTTP requests to the appropriate endpoints provided by the blockchain node. These endpoints usually require you to specify the HTTP method (such as GET, POST, or PUT) and the necessary parameters in the request body or as query parameters. The API documentation of your chosen CrossFi Chain can provide more details and examples on how to access and use the CrossFi Chain API backed by Cross Finance.

Testnet vs mainnet nodes: What's the difference?

CrossFi Chain mainnet nodes are used for “real” applications with assets having economical value. Testnet CrossFi Chain nodes can only host simulation of dApps with sandbox tokens designed for experiments. Therefore, CrossFi testnet requires no “real” crypto for testing and interactions.

Dedicated vs shared XFI RPC nodes: Are they different?

Dedicated CrossFi Chain nodes should be referred to isolated servers with specific software that only serve one user each. With dedicated nodes, customers don’t need to share the resources with their peers. Shared CrossFi Chain XFI nodes represent cheaper options when the same node is utilized by various clients.
