Using Custom Network Fees for Bitcoin Transactions in Ledger Live
Using custom network fees for Bitcoin (BTC) transactions in Ledger Live allows you to control the cost and speed of your transactions, optimizing for savings or urgency depending on network conditions.
Ledger Live offers a flexible fee customization feature for Bitcoin, making it easy to adjust fees to your preference while maintaining the security of your Ledger hardware wallet.

Below, I’ll guide you through how to set custom fees in Ledger Live, explain how it works, and provide tips to get the most out of it.
Why Custom Fees Matter
Bitcoin transaction fees are paid to miners to prioritize your transaction in the blockchain’s mempool (queue of pending transactions). Fees are calculated in satoshis per byte (sat/byte) based on the transaction’s size and network demand:
- High Fees: Faster confirmation (e.g., next block, ~10 minutes).
- Low Fees: Slower confirmation (hours or days) but cheaper.
- Custom Fees: You decide the trade-off, avoiding overpaying or delays.
Ledger Live’s default fee settings (“High,” “Standard,” “Low”) are estimates, but custom fees give you precision, especially during volatile fee markets.
Step-by-Step: Setting Custom Fees in Ledger Live
Here’s how to send a Bitcoin transaction with a custom fee:
1. Connect Your Ledger Device
- Plug your Ledger (e.g., Nano S, Nano X) into your computer via USB or connect via Bluetooth (Nano X).
- Unlock it with your PIN and open the Bitcoin app on the device (navigate to “Bitcoin” and press both buttons).
2. Open Ledger Live and Select Your BTC Account
- Launch Ledger Live on desktop (mobile doesn’t support custom fees yet).
- Go to the “Accounts” tab in the sidebar.
- Click your Bitcoin account (e.g., “Bitcoin – Main”) containing the BTC you want to send.
3. Initiate the Send Transaction
- Click the “Send” button in the account dashboard.
- Enter:
- Recipient Address: Paste the BTC address (e.g., bc1… for SegWit, 1… for Legacy). Double-check it!
- Amount: Specify how much BTC to send (e.g., 0.01 BTC).
4. Customize the Network Fee
- After entering the recipient and amount, click “Continue.”
- You’ll see the fee selection screen with three defaults:
- High: Fastest (e.g., 50 sat/byte).
- Standard: Balanced (e.g., 20 sat/byte).
- Low: Cheapest (e.g., 5 sat/byte).
- Select “Custom” (or “Advanced” in some versions) to set your own fee:
- A slider or input box appears.
- Enter your desired satoshis per byte (e.g., 10 sat/byte).
- Ledger Live estimates the confirmation time based on current mempool data (e.g., “2 hours” or “6 blocks”).
5. Review Transaction Details
- Check:
- Total Fee: Calculated as transaction size (bytes) × fee rate (sat/byte), converted to BTC (e.g., 200 bytes × 10 sat/byte = 2,000 satoshis = 0.00002 BTC).
- Amount Sent: Ensures it matches your intent.
- Remaining Balance: Confirms you have enough BTC for the fee.
- Click “Continue” if everything looks good.
6. Confirm on Your Ledger Device
- Ledger Live sends the transaction to your device for signing.
- On your Ledger:
- Verify the recipient address, amount, and fee match what you entered (scroll through screens).
- Press both buttons to “Accept and Send” (reject if anything’s off).
- The transaction broadcasts to the Bitcoin network.
7. Track Confirmation
- Ledger Live shows a “Pending” status in the transaction history with a transaction ID (TXID).
- Check progress on a block explorer like mempool.space by pasting the TXID—see how many confirmations it has (1 confirmation = ~10 minutes).
How Fees Are Calculated
- Transaction Size: Depends on inputs (UTXOs being spent) and outputs (recipients). A typical single-input, single-output SegWit transaction is ~150-200 bytes.
- Fee Rate: Your chosen sat/byte (e.g., 10 sat/byte).
- Total Fee: Size × Rate (e.g., 200 bytes × 10 sat/byte = 0.00002 BTC).
- Network Impact: Higher rates get priority when the mempool is full (busy network).
Tips for Using Custom Fees
- Check Mempool Conditions:
- Visit mempool.space to see current fee rates:
- 1-2 sat/byte: Low priority, confirms in hours/days (quiet network).
- 5-10 sat/byte: Medium, confirms in ~1-2 hours.
- 20+ sat/byte: Fast, confirms in next block or two.
- Adjust your custom fee based on this data.
- Visit mempool.space to see current fee rates:
- Use SegWit Addresses:
- Ledger Live defaults to SegWit (bc1…) for BTC accounts, which reduces transaction size by ~20-40% compared to Legacy (1…), lowering fees.
- Ensure your recipient accepts SegWit (most modern wallets do).
- Time It Right:
- Fees drop during low network activity (e.g., weekends, late UTC hours). Set a low custom fee (e.g., 3-5 sat/byte) then.
- Avoid Overpaying:
- Default “High” fees can be excessive (e.g., 50 sat/byte when 10 would suffice). Custom fees prevent this.
- Test Small Amounts:
- Send a tiny amount (e.g., 0.001 BTC) with a low custom fee to gauge confirmation time before a big transfer.
Example
- Scenario: Send 0.05 BTC to a friend.
- Mempool: 8 sat/byte for 1-hour confirmation.
- Steps:
- In Ledger Live, enter the address and 0.05 BTC.
- Set custom fee to 8 sat/byte.
- Transaction size: ~180 bytes → Fee = 1,440 satoshis (0.0000144 BTC).
- Sign on Ledger, send, and confirm in ~1 hour.
- Savings: Default “Standard” (20 sat/byte) would’ve cost 0.000036 BTC—custom saves ~60%.
Limitations
- No Batch Support: Custom fees apply to one recipient at a time—use Electrum with Ledger for multi-recipient batching (see prior response).
- Desktop Only: Mobile Ledger Live lacks custom fee options.
- Risk of Delay: Too low a fee (e.g., 1 sat/byte during congestion) might stall your transaction for days until the mempool clears.
Why It’s Useful
Custom fees in Ledger Live give you control:
- Save Money: Pay only what’s needed (e.g., $0.50 vs. $2 during low demand).
- Speed Up: Bump fees (e.g., 30 sat/byte) for urgent sends.
- Stay Secure: Ledger’s hardware signing keeps it safe, unlike online wallets.
Final Thoughts
Using custom network fees for Bitcoin in Ledger Live is a powerful way to tailor your transaction costs and timing. Check mempool.space, set a rate (e.g., 5-15 sat/byte for balance), and sign with your Ledger—it’s that simple.
