Aurora

Aurora is an EVM-compatible blockchain platform that lets developers launch fully customizable Virtual Chains running as smart contracts on the NEAR Protocol, pairing full Ethereum tooling compatibility with NEAR's low fees, sub-second block times, and fast finality. Developers integrate with Aurora primarily through its Ethereum-compatible JSON-RPC API (public mainnet and testnet endpoints), the Rainbow Bridge for moving assets between Ethereum, NEAR, and Aurora, block explorers, price oracles, data indexers, and the Aurora Cloud platform for spinning up dedicated virtual chains. Aurora ships open-source Rust engine crates and SDK, a Rust command-line interface, and TypeScript widgets for building intents-based cross-chain swaps.

Aurora publishes 1 API on the APIs.io network. Tagged areas include Company, Blockchain, EVM, Web3, and JSON-RPC.

Aurora’s developer surface includes documentation, getting-started guide, engineering blog, support, CLI, authentication, sandbox, and 16 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/aurora: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
