# Lethean Wallets

### CLI Wallet (recommended for testnet)

The command-line wallet is the most complete and tested option. Available for Linux x86_64.

- [CLI usage guide](/docs/use/wallets/using-lethean-cli-wallet-ubuntu)

### Browser Extension

**Lethean Companion** (v1.1.10) — a MetaMask-like extension that connects web apps to your wallet. Built and tested against the testnet.

- [How to use](/docs/use/companion)

### Wallet RPC

For automated services, exchanges, and bots — run the wallet CLI in RPC mode:

```bash
./lethean-wallet-cli --wallet-file my-wallet --password "" \
  --daemon-address 127.0.0.1:36941 \
  --rpc-bind-port 36944 --rpc-bind-ip 127.0.0.1
```
