Ankr

• Name: Ankr
• URL: https://www.ankr.com/
• Category: blockchain infrastructure platform / multichain RPC and indexed API provider / rollup-sidechain and staking control plane
• Summary: Ankr is mostly a managed multichain infrastructure vendor: RPC, indexed APIs, packaged chain services, and staking under one console. The point is not that the menu is long. It is that endpoint policy, indexing access, deployment defaults, and staking operations can all sit inside the same operator surface.
• What it does:
  • Provides public, premium, and enterprise RPC/REST/WebSocket access across 80+ blockchains through its Node API surface
  • Sells higher-level indexed “Advanced APIs” for NFT, token, and cross-chain query workflows so developers can request common blockchain data with fewer calls
  • Offers contract-automation tooling for time-based or event-based smart-contract execution from a dashboard-driven workflow
  • Markets scaling services for launching sidechains or rollups plus additional marketplace components for custom chain deployments
  • Runs staking and liquid-staking products alongside developer tooling, making the platform both app-facing and asset-operation-facing
• Key claims:
  • The homepage says Ankr delivers 56 ms average response time, 99.99% uptime, support for 70+ blockchains, and a DePIN-backed global node footprint spanning 30+ regions and billions of daily RPC requests
  • The docs home says Ankr’s products are all powered by a globally distributed and decentralized network of nodes and groups them into Node API, Advanced API, contract automation, scaling services, staking, and tutorials
  • The Node API docs say developers can interact with 80+ supported blockchains, which is slightly broader than the homepage’s 70+ figure and worth recording as a surface-level coverage discrepancy rather than flattening
  • The Advanced API docs say Ankr optimizes, indexes, caches, and stores blockchain data, supports multi-chain requests in a single call, and exposes NFT, query, and token methods across multiple mainnets and testnets
  • The pricing page shows Ankr selling not just simple HTTPS RPC but also WSS, gRPC, whitelists, statistics, and differentiated rate-limit tiers, which reinforces the control-plane framing
  • The verified GitHub organization exposes JavaScript and Python SDKs plus game and ecosystem tooling, which confirms a broader developer-platform posture beyond a single API gateway
• Whitepaper: No canonical standalone Ankr whitepaper or litepaper surfaced in this pass. The clearest current source of truth is the official site, docs suite, pricing pages, and verified GitHub organization; see ../whitepapers/ankr-primary-sources-2026-04-27.md.

Internal linkages

• Best comparison points for managed chain infrastructure: blockdaemon, validation-cloud, and kiln.

• Use the note when the real question is who controls endpoint policy, indexing access, and deployment defaults rather than who merely serves raw node traffic.
