Frequently asked questions about the Ink API
What is Ink Chain?
Ink Chain is a high-performance Layer 2 blockchain developed by Kraken, designed to offer users a seamless bridge to DeFi with low transaction costs and fast execution times. It is built on Optimism's Superchain and is compatible with the Ethereum ecosystem, enabling developers to deploy Ethereum-based applications seamlessly on it.
What is the Ink Chain API?
The Ink Chain API facilitates interaction with the Ink network through a collection of JSON-RPC methods. Given its compatibility with the Ethereum ecosystem, developers familiar with Ethereum's JSON-RPC APIs will find working with Ink both intuitive and straightforward.
How can I get started using the Ink API?
Explained in Ink API Quickstart.
Is Ink EVM compatible?
Yes, Ink Chain is fully compatible with the Ethereum Virtual Machine (EVM). This compatibility allows Ethereum developers to port their projects to Ink with minimal changes, taking advantage of the chain's high throughput and low transaction fees.
What API does Ink use?
Ink Chain uses the JSON-RPC API standard for blockchain interactions. This is the same standard used by Ethereum.
What is an Ink API key?
When accessing the Ink network via a node provider like Alchemy, Ink developers use an API key to send transactions and retrieve data from the network.
