Chainstack introduces World Chain Mainnet support

We’re excited to announce that Chainstack now supports World Chain — an OP Stack Layer 2 rollup built to prioritize verified humans onchain. Starting today, you can deploy production-ready World Chain Mainnet nodes on Chainstack in under two minutes, with full debug and trace namespace support.

Why build on World Chain?

World Chain is an EVM-compatible Layer 2 rollup built on the OP Stack and part of the Optimism Superchain, designed from line one for applications that benefit from verified-human participation. Where general-purpose L2s optimize for throughput and treat every address the same, World Chain inverts the model — verified humans are first-class citizens, and the network’s economics reflect that.

• Priority for verified humans: Users who verify with World ID receive priority blockspace and partial gas subsidies, protecting the network from bot-dominated activity and giving real users a smoother onchain experience.
• Zero-knowledge proof-of-humanness: World ID uses zero-knowledge proofs so users can prove they’re unique humans without revealing their identity — a primitive that unlocks sybil-resistant airdrops, one-person-one-vote governance, and human-gated applications that weren’t possible before.
• Ethereum-secured through the Superchain: World Chain settles to Ethereum through the OP Stack, inheriting Ethereum’s security guarantees while giving developers L2 economics and shared interoperability with Optimism, Base, and every other Superchain member.
• Full EVM compatibility: Solidity contracts, ethers.js, viem, Foundry, Hardhat — everything you already use for Ethereum and Optimism works on World Chain without modification. Any OP Stack contract ports directly.
• Reach real users at scale: World Chain is home to World App, giving developers a distribution channel to over 15 million verified people across 160 countries — the largest verified-human user base onchain.

For developers, World Chain Mainnet is the on-ramp to a chain where sybil resistance is a protocol-level primitive, not something you have to solve at the application layer.

Build better with World Chain on Chainstack

Running World Chain Mainnet on Chainstack gives you reliable access and predictable performance for any workload — from mini-app deployments and identity-gated applications to indexing, analytics, and consumer-facing dApps. Chainstack provides:

• Global Nodes — geo-balanced RPC endpoints for scalable, low-latency access to World Chain Mainnet
• Full and Archive nodes — recent state or full history from genesis, matched to your workload
• Full debug and trace namespaces on archive — debug_* and trace_* methods for transaction replay, call tracing, and smart-contract debugging
• Standard Ethereum JSON-RPC compatibility — HTTPS and WebSocket endpoints that work with any EVM toolchain you already have

How to get started with World Chain on Chainstack

1. Log in to the Chainstack console (or create an account)
2. Create a new project
3. Select World Chain as your blockchain protocol
4. Choose Mainnet and Global Node
5. Deploy the node
6. Open Access and credentials and copy your HTTPS and WebSocket endpoints

Bringing it all together

With support for World Chain Mainnet, Chainstack extends its infrastructure coverage into the Optimism Superchain — and specifically into the emerging category of identity-native applications. Whether you’re building mini apps, sybil-resistant DeFi, identity-gated grants, or any product that touches World Chain, Chainstack provides the low-latency, production-grade RPC infrastructure to scale with confidence.
