ThunderCore

ThunderCore is an EVM-compatible layer-1 public blockchain with roughly one-second block times and single-block finality, using TT as its native gas token (chain ID 108). Its external protocol is Ethereum-compatible, so standard Ethereum JSON-RPC methods, wallets, and Solidity toolchains (Hardhat, Foundry, Truffle, Remix) work against the public RPC and WebSocket endpoints, alongside a BlockScout explorer API, official subgraphs on The Graph, a cross-chain bridge, and a public testnet with a faucet. Backed by Pantera Capital.

ThunderCore is listed with 4 APIs on the APIs.io network. Tagged areas include Company, Crypto, Blockchain, EVM, and JSON-RPC.

The ThunderCore catalog on APIs.io includes 1 event-driven AsyncAPI specification.

ThunderCore’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, sandbox, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/thundercore: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
