# Bitcoin Accelerator

## 1. Introduction

[**Bitcoin Accelerator**](https://tools.mempool.com/speed) is a high-performance Bitcoin transaction accelerator built to resolve stuck or delayed transactions caused by low fees or network congestion. Leveraging the **Child Pays for Parent (CPFP)** mechanism, it enables users to quickly boost the confirmation speed of pending transactions directly on the Bitcoin mainnet.

Whether you're managing high-frequency mints or simply need a critical transaction to go through, Bitcoin Accelerator provides an efficient, secure, and user-friendly solution.

## 2. How It Works

#### 🔁 CPFP Acceleration Strategy

Bitcoin Accelerator is powered by the CPFP model — a native Bitcoin method for reprioritizing unconfirmed transactions:

* **Mechanism**: When a transaction is pending due to insufficient fees, a new “child” transaction is constructed that spends its output and pays a higher combined fee.
* **Effect**: Miners are incentivized to include both the parent and the child in the same block since the child’s fee covers the cost of both.

#### ⚙️ Workflow

```
[Pending Transaction A]
        ↓
[User submits TXID to Bitcoin Accelerator]
        ↓
[System generates Child Transaction B with a higher fee]
        ↓
[Child Transaction B is broadcast → Miner confirms A + B together]
```

## 3. Key Features

#### ✅ One-Click Acceleration

Submit a stuck transaction’s TXID — the system automatically calculates, constructs, and broadcasts a high-fee child transaction.

#### ⚡ Fast Confirmations

Even during high-congestion periods, Bitcoin Accelerator significantly reduces wait times, ensuring that your transaction gets confirmed in the next few blocks.

#### 📦 Batch Acceleration for Minters

Perfect for users who perform multiple mints:

* Detects multiple pending transactions automatically
* Allows batch acceleration with a single signature
* Minimizes manual input for power users
