KuCoin

Discover Kucoin Chain, an EVM-compatible blockchain for decentralized finance. Build scalable dApps using the RPC gateway and tools.

The Kucoin RPC documentation provides developers with a guide to interact with Kucoin’s blockchain network. Kucoin Chain is an EVM-compatible blockchain designed for decentralized finance (DeFi) and asset management. Through the RPC gateway, developers can query blockchain data, submit transactions, and manage smart contracts efficiently. Kucoin’s proof-of-stake (PoS) consensus mechanism ensures low fees and fast transactions, making it ideal for building scalable decentralized applications (dApps).
