Learn more about Kroma

What is Kroma?

Kroma is an optimistic rollup that plans a trustless transition to zk proofs; it rolls up to Ethereum and emphasizes Korean gaming projects.

How to get Kroma RPC endpoint?

Create a free account at Chainstack and log in to the console. Click Add node, pick Kroma (mainnet or testnet), and deploy a dedicated node in seconds. When the node shows as running, go to Access & credentials to copy your HTTPS and WebSocket RPC endpoints.

How to run a Kroma node?

Kick off a Global Node on Chainstack and Kroma’s optimistic stack is ready to query. Go Dedicated Node when you need sandboxed sequencer feeds. Self-hosters must maintain op-node, plan the zk-transition, and monitor Korean RPC clusters.

What is Kroma RPC API?

Kroma’s RPC is Optimism-compatible today but plans a zk transition accessible through kroma_getZkStatus. Standard eth_* calls deploy contracts, while sequencer endpoints handle Korean gaming micro-payments. Both optimistic and zk finality can be queried in one place.

How much does it cost to run a Kroma RPC?

A Kroma node sits near US $100-180 / month, with future zk-proof modules likely boosting CPU cost. Frequent releases mean higher engineer hours. Chainstack’s Kroma RPC is the cost-efficient alternative for nearly all use cases.

Is Kroma RPC free?

Kroma’s public RPC is free, yet Korean gaming spikes lead to timeouts. Chainstack’s no-charge tier supports 3 million dependable Kroma requests.

How to setup a Kroma RPC?

Copy the Kroma RPC URL in Chainstack. Enter it into your wallet’s RPC list or into your provider config to switch calls to Kroma.

Notes for Kroma API

When communicating with a Kroma node, the client implements a JSON-RPC specification based on the OP Stack. The recommended libraries are ethers.js for JavaScript or web3.py for Python.

OP Stack-based ZK rollup that combines optimistic and ZK proving mechanisms.

You can also access Kroma directly through the Chainstack MCP server — query live on-chain data, deploy nodes, request testnet funds from the faucet, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.
