ZAN review
RPC, indexing, alerts and streaming for teams building across blockchain networks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZAN provides cloud-based blockchain infrastructure for developers and teams that need API access to public networks. Its Node Service offers JSON-RPC over HTTPS and WebSocket, while a single API key can provide access to 20+ blockchains. The published Node Service plans list 27+ supported chains. Solo developers, small teams and larger organizations can also use a Contract Indexer to parse and query contract data, set up event alerts, and stream supported-chain data through gRPC. SDK options include ZAN SDK, ethers, web3.js, web3.py and web3j.
The plan structure gives developers a free starting point, then increases credits, approximate request capacity, API-key allowances and throughput at each listed paid tier. Free includes 150 million credits per month, approximately 15 million requests, up to 3 API keys and 270 credits per second. Growth costs $49 per month and includes 330 million credits, approximately 25 million requests, up to 10 API keys and 2,700 credits per second. Pro is $299 per month, with 2.3 billion credits, approximately 150 million requests, up to 30 API keys and 6,700 credits per second. Enterprise is custom. The higher tiers make sense when request volume or throughput exceeds the free allowance.
ZAN’s strongest fit is teams that need managed RPC access alongside indexing and event delivery, rather than a standalone endpoint. Dedicated single-tenant nodes, API key security settings, and Solana transaction routing through Trading Boost add infrastructure options; gRPC streaming is available for supported chains. The main boundary is scope: documented services focus on access, data retrieval, alerts and routing, not contract authoring, testing or deployment. Teams looking for a complete smart-contract development workflow should compare other platforms, while those assembling their own tools around multi-chain RPC and on-chain data may find ZAN a closer match. Community is the listed support channel.
