Qt desktop wallet — getting started guide

The INTcoin desktop wallet is a standalone application with an embedded full node. No external daemon or server setup is required — launch the wallet and it handles everything.

First Launch

When you start intcoin-qt for the first time, the setup wizard walks you through:

  1. Create or restore wallet — Generate a new 24-word mnemonic seed phrase, or restore from an existing one.
  2. Write down your seed phrase — This is the only time it’s displayed. Store it securely offline. If you lose it, nobody can recover your funds.
  3. Set a passphrase (optional but recommended) — Encrypts the wallet file on disk.

After setup, the wallet begins synchronising the blockchain. This takes some time on first run as it downloads and verifies every block from genesis.

Main Tabs

Overview — Balance display (confirmed, pending, immature from mining), recent transactions.

Send — Enter a recipient address (int1q...), amount, and optional label. Fee estimation is automatic. Supports multiple recipients in a single transaction.

Receive — Generate new receiving addresses with optional labels. QR codes are generated automatically.

History — Full transaction log with filtering by type (sent, received, mined), date range, and text search. Export to CSV.

Mining — Start and stop mining directly from the wallet. Set the number of CPU threads to use. The wallet mines to one of your own addresses.

Wallet Encryption

Go to Settings > Encrypt Wallet to set a passphrase. Once encrypted:

  • The wallet locks automatically after a timeout
  • You must unlock to send transactions or export keys
  • Mining continues while locked (it only needs a receiving address)
  • You can change the passphrase via Settings > Change Passphrase

Coin Control

For advanced users, coin control lets you choose exactly which UTXOs to spend in a transaction. Access it from the Send tab. You can also lock individual UTXOs to prevent them from being spent by automatic coin selection.

Fee Bumping (RBF)

If a transaction is stuck unconfirmed, right-click it in the History tab and select Bump Fee. This creates a replacement transaction with a higher fee. Works for any transaction that signals RBF (nSequence < 0xfffffffe), which is the default.

Backup

Settings > Backup Wallet copies the wallet file to a location you choose. You should also keep your 24-word seed phrase stored securely — it can restore the entire wallet on any machine.

Settings > Export Private Keys exports all keys as hex strings. This is a secondary backup method.

Testnet Mode

Launch with --testnet to use the testnet:

./intcoin-qt --testnet

RPC Mode

Advanced users can connect the wallet to a remote intcoind instead of running an embedded node:

./intcoin-qt --rpc --rpcconnect=192.168.1.100 --rpcport=2211

Debug Window

Help > Debug Window gives you:

  • Information — Node version, network, block height, connections, data directory
  • Peers — Connected peer table with ban management
  • Console — Direct RPC command entry (same commands as intcoin-cli)
  • Log — Recent log entries with filtering
