Testnet is the public test chain — same rules as mainnet, no real
value. Use it for integration testing, wallet experiments, and
learning the RPC.
1. Run a testnet node
intcoind -testnet -daemon
Datadir is automatically ~/.intcoin/testnet/. P2P on 12210,
RPC on 12211. Sync is fast (the chain is small).
Check progress:
intcoin-cli -testnet getblockchaininfo
2. Get a testnet address
intcoin-cli -testnet getnewaddress
# tint1q... (note the testnet HRP)
3. Get coins from the faucet
Public testnet faucet: https://faucet.international-coin.org
Paste your tint1q... address. The faucet sends a small amount and
the tx confirms within a couple of blocks.
Verify:
intcoin-cli -testnet getbalance
4. Send coins back (or to a friend)
intcoin-cli -testnet sendtoaddress tint1qotheraddress... 5.0
Returns a txid. Find it in the testnet explorer
(when public — for now: intcoin-cli -testnet gettransaction <txid>).
5. Mine on testnet (optional)
The standalone miner works on testnet:
intcoin-miner -testnet \
-address=tint1q... -threads=4 \
-rpcuser=YOUR_USER -rpcpassword=YOUR_PASS
Difficulty is much lower than mainnet — you’ll find blocks in seconds.
Useful for testing reward flows and template generation.
Reset testnet
Want a clean slate? Stop intcoind, delete ~/.intcoin/testnet/,
restart. The node will resync from the public testnet.
Don’t confuse it with signet
Signet (port 22210 / 22211) is a more controlled developer chain
where blocks are signed by a single authority. See
Testnet & Signet for signet-specific topics.
