Essential tools and information for building on KalyChain.
RPC Endpoints
KalyChain runs a single public network (chain ID 3890, native token KMT). The former
mainnet 3888 and testnet 3889 were retired at the relaunch, along with their endpoints.
| Type | URL | Chain ID |
|---|---|---|
| HTTP | https://mainrpc.kalychain.io/rpc | 3890 |
| WSS | wss://mainrpc.kalychain.io/ws | 3890 |
Explorer
Testnet
There is no public testnet at present. A new one is planned; this page will list its endpoints and faucet when it launches.
Tooling Compatibility
KalyChain is fully compatible with standard EVM developer tools:
- Hardhat: Use standard configuration with KalyChain RPCs
- Foundry: Fully supported
- Remix IDE: Connect via "Injected Provider - MetaMask"
- Ethers.js / Web3.js: Standard implementation
Verification
Contracts can be verified on the block explorer using the standard API or direct source code upload.
