Frequently asked questions about the World Chain API
What is World Chain?
World Chain is a blockchain designed for humans, developed by Worldcoin. It aims to accelerate the adoption of Proof of Personhood and decentralized finance in the age of AI. World Chain provides a platform where verified humans get priority blockspace over bots and a gas allowance for casual transactions, creating an ecosystem focused on utility for everyday life.
What is the World Chain API?
The World Chain API allows developers to interact with the World Chain network through a set of JSON-RPC methods. It supports various operations such as smart contract deployment, transaction processing, and data retrieval, enabling developers to integrate World Chain's functionality into their applications.
How can I get started using the World Chain API?
Explained in World Chain API Quickstart.
Is World Chain EVM compatible?
Yes, World Chain is EVM-compatible. As an Ethereum Layer 2 solution, it allows developers to deploy Ethereum-based smart contracts and applications on the World Chain network, leveraging existing Ethereum development tools and practices.
What API does World Chain use?
World Chain utilizes the JSON-RPC API standard, which is widely used in the Ethereum ecosystem. This provides a familiar and efficient interface for blockchain interactions.
What is a World Chain API key?
When accessing the World Chain network via a service provider, developers need an API key to send transactions and retrieve data. An API key ensures secure and authenticated access to the network.
Which libraries support World Chain?
As an EVM-compatible blockchain, World Chain supports popular Ethereum libraries such as Web3.js and Ethers.js. This allows developers to leverage existing tools and knowledge when building on World Chain.
How does World Chain prioritize human users?
World Chain uses World ID's Proof of Personhood system to verify human users. Verified humans receive priority blockspace and a gas allowance for transactions. This verification is optional and anonymized through zero-knowledge proofs.
