Chainstack vs OpenZeppelin: Node RPC vs Smart Contracts
Chainstack is a managed infrastructure platform that provides RPC endpoints, dedicated node hosting, and subgraph indexing across more than 70 blockchains. OpenZeppelin provides open-source smart contract libraries and security advisory services for onchain application security and execution.
The two platforms address different technical needs. Chainstack operates external network connectivity, routing API traffic through more than 10 global data centers under a 99.99% uptime SLA. Its plans begin at $49 per month after a free 3-million request tier. OpenZeppelin secures the code layer itself, providing audited token standards and access control modules alongside self-hosted Relayer and Monitor utilities under AGPL-3.0 and MIT licenses. While Chainstack delivers data access to chains, OpenZeppelin supplies the standard smart contracts that run on those networks.
Quick verdict
The choice comes down to whether your project requires external node connectivity and RPC routing, or smart contract standards and security validation. Chainstack runs the remote infrastructure needed to read chain state and broadcast transactions, charging monthly subscriptions for dedicated compute and high request volumes. OpenZeppelin provides the audited logic and open-source tooling required to write, deploy, and secure smart contracts. Paid options are limited to custom institutional advisory and audits.
Choose Chainstack if your team needs managed RPC endpoints or dedicated nodes across networks like Ethereum, Solana, and Bitcoin without handling raw node hardware. Needs vary. Paid plans start at $49 per month, with options for flat-rate RPS tiers or self-hosted node orchestration.
Choose OpenZeppelin if you are authoring token contracts, configuring onchain access controls, or looking for institutional smart contract audits. Its contract libraries and self-hosted Relayer and Monitor tools are free under open-source licenses, requiring internal engineers to manage their own operational deployment.

FAQ
Is Chainstack cheaper than OpenZeppelin?
OpenZeppelin is free for its core contract libraries and developer tools, while Chainstack charges monthly fees for paid infrastructure tiers. Chainstack offers a free tier with 3 million monthly request units, but production plans start at $49 per month. OpenZeppelin charges only for custom security audits and advisory programs.
What networks do Chainstack and OpenZeppelin support?
Chainstack supports more than 70 networks, including Bitcoin, Ethereum, Solana, TON, and X Layer for RPC data. OpenZeppelin provides contract standards and tooling across EVM networks like Arbitrum and Base, as well as non-EVM chains such as Solana, Stellar, TRON, Canton, and Midnight.
Does OpenZeppelin host RPC nodes like Chainstack?
No, OpenZeppelin does not provide managed RPC nodes or node hosting. OpenZeppelin provides smart contract libraries, transaction relaying scripts, and security reviews. Teams using OpenZeppelin tooling connect to external RPC providers like Chainstack to communicate with blockchains.
Can you run self-hosted infrastructure on both platforms?
Yes, both platforms offer self-hosted deployment options. Chainstack introduced a Self-Hosted control plane to run nodes on customer-owned infrastructure. OpenZeppelin distributes its Relayer and Monitor tooling under the AGPL-3.0 license for teams managing their own transaction automation pipelines.
