https://testnetwallet.netA free, open-source wallet for Bitcoin testnet4 and Litecoin testnet, built for learning and for testing before you touch mainnet. It runs entirely in the browser: your keys are generated locally and never leave it, there's no server I run, and it's a no-build static site, so you can self-host it (clone the repo, drop the folder on any static host, or run it locally) and it works over Tor.
Honest caveat: it's a light wallet, not its own node. Balances, history, broadcasting, and the in-wallet faucet go through public Esplora-style explorer APIs (litecoinspace.org for Litecoin, mempool.space for Bitcoin), so those services see your addresses, like any light/SPV wallet. If you self-host, you can point it at your own Esplora instance for full independence.
Features- BIP39 HD wallet (create or import); Legacy, SegWit (bech32) and Taproot addresses
- Send to multiple recipients, manual sat/vB fees, coin control, OP_RETURN, RBF and CPFP
- Multisig: build/import P2WSH descriptor wallets (BIP48), coordinate a spend over PSBT
- Electrum seed import; message signing/verification (legacy BIP-137 and BIP-322)
- Dev tools: decode a raw tx or PSBT, broadcast raw, build BIP21/QR
- Get free test coins via CypherFaucet, in-wallet
- Optional password encryption-at-rest; installable PWA with some offline functionality
Learning by doing: because it's testnet the coins have no real value, so it's a safe place to see how things actually work instead of just reading about them: derive Legacy/SegWit/Taproot addresses from one seed and compare them, watch a transaction confirm, RBF a stuck fee, decode a raw tx or PSBT to inspect its anatomy, or stand up a multisig and coordinate a spend, all without risking anything. There's a beginner walk-through built in, and it doubles as a sandbox for devs testing flows before mainnet.
Roadmap: Litecoin MWEB (receive-side) is in development; Monero testnet/stagenet are coming back shortly (pending my CORS-enabled nodes syncing); non-custodial cross-chain atomic swaps (adaptor signatures) are further out.
Testnet only, so the coins have no real value. Still in active development; feedback and bug reports welcome.
