Frequently Asked Questions

What are the uptime and performance guarantees?

We offer a 99.99%+ uptime SLA on our dedicated Ink RPC nodes, backed by enterprise-grade infrastructure optimized for low-latency and high-throughput performance.

How long does it take to activate access after submitting a request?

You will receive your connection credentials after our support team processes your request, which typically takes 1–2 business days.

What pricing or billing options are available for RPC access?

We offer flexible monthly and annual billing plans. Dedicated node deployment requires a Pro plan subscription and higher.

Dedicated Node compute per hour price starts from $0.50 across all paid subscription plans.

Can I monitor usage or performance metrics of my node?

Yes, we provide a user dashboard with real-time metrics, including request counts, latency, and system health, allowing you to monitor and optimize your usage.

Learn more about Ink

What is Ink?

Ink! is Parity’s Rust-based smart-contract language for Substrate chains; it compiles to Wasm and adds type safety and testing tools.

How to get Ink RPC endpoint?

Open a free Chainstack account, then access your console. Hit Add node, pick the Ink network, and spin up your node with one click. Once it’s up, click Access & credentials and take your personal RPC endpoint into your dApp.

How to run an Ink node?

Launch an Ink-compatible Global Node on Chainstack to test Wasm contracts fast. Reserve a Dedicated Node for enterprise Substrate chains. Self-hosting needs Rust nightly toolchains, Wasm-opt passes, and relay topologies.

What is Ink RPC API?

Ink! contracts run on Substrate, whose nodes expose RPCs like contracts_call and contracts_subscribe. Developers pass SCALE-encoded inputs and receive raw byte outputs. Frontier adds eth-style wrappers for EVM compatibility.

How much does it cost to run a Ink RPC?

Running a Substrate node with ink! contract pallets costs about US $100-180 / month. Build pipelines and Wasm optimizations add people-hours. Using Chainstack’s Substrate RPC often wins on cost.

Is Ink RPC free?

Substrate dev nodes are free, yet community RPC can vanish. Chainstack’s free tier offers 3 million Ink/Frontier calls that stay online.

How to setup a Ink RPC?

Copy the Frontier RPC/WebSocket URL for your ink! chain in Chainstack. Provide that endpoint to Polkadot{.js} or to your Rust SDK to deploy Wasm contracts.

Notes for Ink API

When communicating with an Ink 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.

Kraken's EVM-compatible L2 built on the OP Stack, focused on DeFi and crypto-native applications.

You can also access Ink 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.
