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 publishes 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.

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