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.
