# VinuChain Testnet

VinuChain testnet (chain ID `206`) is the parallel public test network. It runs the full ELEMONT binary plus additional experimental stages (VinuBLS12381, VinuLatestEVM, PaybackV2) that are not yet staged on mainnet. Use it to test contracts and integrations against the latest chain features before they reach mainnet. This section covers connecting to testnet, running a private fakenet, and the operator-facing chain upgrade guide.

For all chain IDs, RPC endpoints, and explorer URLs in one place, see [Network Details](/vinuchain/technical-docs/network-details.md).
