Run a Litecoin testnet node

Why run a node #

A node lets you validate the chain yourself instead of trusting a third party, and it gives you full RPC access to explore and broadcast. The Litecoin testnet is small, so it's a friendly first node. MWEB is built into Litecoin Core, so you get that too.

Install #

Download Litecoin Core from the official Litecoin project and install it. It ships two programs you'll use: litecoind (the daemon) and litecoin-cli (the command-line client).

Configure #

Create a litecoin.conf. A minimal, safe testnet config:

# litecoin.conf
testnet=1
server=1

[test]
# Bind RPC to localhost only (this is the default; shown for clarity)
rpcbind=127.0.0.1
rpcallowip=127.0.0.1
# Prefer cookie auth (auto-generated .cookie) over a plaintext password

Leaving rpcpassword out means Litecoin Core uses cookie authentication: it writes a temporary .cookie file that litecoin-cli reads automatically. That's safer than a password in a config file. The [test] section scopes settings to testnet.

Start & sync #

litecoind -testnet                       # start the daemon
litecoin-cli -testnet getblockchaininfo  # check sync progress

Watch the block height climb until it matches the network. When getblockchaininfo shows you're at the tip, you're synced.

Use it #

litecoin-cli -testnet getnewaddress          # a fresh receive address
litecoin-cli -testnet getbalance             # your balance
litecoin-cli -testnet sendtoaddress <addr> 0.1
litecoin-cli -testnet sendrawtransaction <hex>   # push a signed tx

Fund your address from the faucet, then see broadcasting a raw transaction for the hands-on path.

The same pattern works for Bitcoin (bitcoind -testnet4, see the Bitcoin guide) and Monero (monerod --stagenet, see the Monero guide).
