## Understanding Transaction Basics

### What Happens When You Send Bitcoin?

```
Your Wallet → Creates Transaction → Broadcasts to Network
                                           ↓
                                    Miners Validate
                                           ↓
                                    Added to Blockchain
                                           ↓
                                    Recipient Receives!
```

### Transaction Components

Every Bitcoin transaction includes:

1. **Input**: Where Bitcoin comes from (your address)
2. **Output**: Where Bitcoin goes (recipient's address)
3. **Amount**: How much to send
4. **Fee**: Payment to miners for processing

## Step-by-Step: Sending Bitcoin

### Step 1: Get Recipient's Address

The recipient needs to provide their Bitcoin address. They can:

* **Show QR code** (easiest)
* **Copy/paste address** (careful!)
* **Send via secure message**

#### Address Formats:

* **Legacy**: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
* **SegWit**: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
* **Native SegWit**: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq

All formats work - newer ones have lower fees!

### Step 2: Open Send Function

In your wallet:

1. Tap "Send" or paper airplane icon
2. Choose Bitcoin (not Lightning)
3. You'll see send screen

### Step 3: Enter Recipient Address

**Method 1: QR Code (Recommended)**

1. Tap QR scanner icon
2. Point at recipient's QR code
3. Address fills automatically
4. Verify it looks correct

**Method 2: Copy/Paste**

1. Copy address from recipient
2. Paste in address field
3. **Triple-check** every character
4. Look for validation checkmark

### Step 4: Enter Amount

You can enter amount in:

* **BTC**: 0.00012345
* **Satoshis**: 12,345
* **Your currency**: $50

Tips:

* Wallet shows your balance
* Can't send more than you have
* Leave some for fees!

### Step 5: Set Transaction Fee

Fees determine speed:

| Fee Level   | Speed      | Use Case       |
| ----------- | ---------- | -------------- |
| 🐌 Low      | Hours/Days | Not urgent     |
| 🚶 Medium   | 30-60 min  | Normal use     |
| 🏃 High     | 10-20 min  | Time sensitive |
| 🚀 Priority | Next block | Urgent         |

Most wallets suggest appropriate fees!

### Step 6: Review Everything

Before confirming, check:

* ✅ Correct recipient address
* ✅ Right amount
* ✅ Acceptable fee
* ✅ Total makes sense

### Step 7: Send!

1. Tap "Send" or "Confirm"
2. Enter PIN/biometrics if required
3. Transaction broadcasts to network
4. You'll see confirmation screen

### Step 8: Track Your Transaction

Your wallet shows:

* Transaction ID (long string)
* Status (pending → confirmed)
* Confirmations counter

## Your First Practice Transaction

## Understanding Confirmations

### What Are Confirmations?

Each new block added after your transaction = 1 confirmation

* **0 confirmations**: Pending (waiting for miners)
* **1 confirmation**: In blockchain (\~10 minutes)
* **3 confirmations**: Very secure
* **6 confirmations**: Irreversible

### Why Wait for Confirmations?

* Small amounts: 1 confirmation usually fine
* Large amounts: Wait for 3-6
* Exchanges: Often require 3-6
* Personal choice based on trust

## Common Transaction Scenarios

### Sending to Friend

1. Meet in person or video call
2. They show QR code
3. You scan and send
4. Both see confirmation

### Paying for Goods/Services

1. Merchant provides address/invoice
2. Often includes exact amount
3. May have time limit
4. Save receipt/transaction ID

### Exchange Deposit

1. Generate deposit address on exchange
2. **Verify correct network** (Bitcoin, not others)
3. Send from wallet
4. Wait for exchange confirmations

### Testing New Wallet

1. Send minimum amount first
2. Verify it arrives
3. Test recovery if needed
4. Then send larger amounts

## Transaction Fees Explained

### What Determines Fees?

Fees based on:

* **Transaction size** (bytes, not Bitcoin amount)
* **Network congestion**
* **Desired speed**

NOT based on:

* Amount being sent
* Distance to recipient
* Wallet being used

### Fee Saving Tips

* Use Native SegWit addresses (bc1...)
* Send during low-congestion times
* Batch multiple payments together
* Consider Lightning for small amounts

## Troubleshooting Common Issues

### "Insufficient Balance"

* Check you have enough for amount + fee
* Wallet might be calculating conservatively
* Try reducing amount slightly

### "Invalid Address"

* Recheck every character
* Ensure it's a Bitcoin address
* Some wallets only accept certain formats

### "Transaction Stuck"

If fee too low:

* Wait - it may confirm eventually
* Use RBF (Replace-By-Fee) if available
* CPFP (Child-Pays-For-Parent) advanced option
* Learn for next time

### "Sent to Wrong Address"

* Cannot be reversed 😔
* Contact recipient if possible
* Expensive lesson learned
* Always double-check!

## Advanced Features

### Replace-By-Fee (RBF)

* Increase fee after sending
* Speeds up stuck transaction
* Not all wallets support

### Coin Control

* Choose specific UTXOs to spend
* Advanced privacy feature
* For experienced users

### Batch Transactions

* Send to multiple addresses
* Saves on fees
* Business use case

## Security During Transactions

### Always:

* ✅ Verify address character-by-character
* ✅ Start with test transaction
* ✅ Use secure internet connection
* ✅ Check wallet is authentic

### Never:

* ❌ Send to address from email
* ❌ Trust "refund" addresses
* ❌ Send under pressure
* ❌ Ignore warning messages

## After Your Transaction

### Save Records

* Transaction ID
* Recipient address
* Amount and fee
* Purpose/notes

### Confirm Receipt

* Ask recipient to confirm
* Check blockchain explorer
* Wait for confirmations

### Learn and Improve

* What went well?
* What was confusing?
* How can you improve?

1. Send $1 to yourself
