Learn more about Ink

What is Ink?

Ink is an Ethereum Layer 2 built by Kraken on the OP Stack, part of the Optimism Superchain. It’s a DeFi-focused chain with 1-second block times, full EVM compatibility, and ETH as its native gas token — no separate ecosystem token.

How do I get an Ink RPC endpoint?

Create a free Chainstack account and sign in. Click Add node, select Ink, and deploy a Global Node on Mainnet. When the node is running, open Access and credentials to copy your HTTPS and WebSocket endpoints.

What is the difference between an Ink Global Node and a Dedicated Node?

An Ink Global Node provides shared, auto-scaling RPC access through geo-balanced infrastructure. A Dedicated Node provides isolated op-reth compute resources, predictable performance, and greater control over node configuration.

Does Ink use a native token?

No. Ink uses ETH as its gas token — unlike some other exchange-launched L2s, it doesn’t introduce a separate ecosystem token.

Is the Ink RPC API compatible with Ethereum?

Yes. Ink is fully EVM-compatible and exposes the standard Ethereum eth_* JSON-RPC and WebSocket interface — the same tooling (ethers.js, web3.py, Hardhat, Foundry) works without modification.

What are the uptime and performance guarantees?

Chainstack Global Nodes and Dedicated Nodes are built for highly available, low-latency production access, with a 99.99% uptime SLA available on Dedicated deployments depending on plan and service terms.

How can I monitor Ink node usage and performance?

Use node analytics on Chainstack to track request volume, response time, and node health from one place.

Notes for Ink API

Ink runs the op-reth execution client and exposes the standard Ethereum JSON-RPC and WebSocket API. Use ethers.js, web3.py, or any standard EVM SDK. Ink Mainnet has chain ID 57073, 1-second block times, and ETH as its gas token. Chainstack currently offers Ink on Mainnet only.

You can also access Ink through the Chainstack MCP server — query onchain data, deploy nodes, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.

Build on Ink with reliable RPC nodes

Reliable, scalable Ink RPC access for DeFi and consumer crypto applications, fully managed by Chainstack.

Consistent performance for every request
