I run a few testnet tools (a faucet, a wallet, an explorer, and now a swap), and people kept landing on them without much idea of how testnets actually work. So I built a hub to tie it together and explain the basics: TestnetHub.
The idea is "learn crypto with fake coins and real protocols". Testnets are practice networks where the coins have no value but the protocols are real, so you can learn how wallets, miners, explorers, nodes, confirmations, fees, and swaps work without touching real BTC, LTC, or XMR. It's not another explorer, wallet, faucet, or swap frontend; it's the map that points to those tools and explains how everything fits together.
What's on it- Step-by-step guides: your first transaction, confirmations, fees, UTXOs, keys and seeds, running a node, broadcasting a raw tx, debugging a stuck tx, RPC safety, regtest, and mining.
- A companion code repo, testnet-examples: short, commented Python and JavaScript recipes for each guide (new key, read the chain, build and broadcast a tx, watch it confirm, Monero daemon and wallet). The read-only ones need no node or keys.
- Per-chain pages for the Bitcoin, Litecoin, and Monero testnets, a glossary, an FAQ, a scams page, and a "why testnet coins have no value" explainer.
- A live status page for the ecosystem services.
- A launchpad into the tools: faucet, pool, wallet, explorer, and swap.
Code is AGPL-3.0, the guides are CC-BY-SA-4.0. Fully static, no framework, no tracking.
