## 🎯 Why BasePy?

### The Problem with Web3.py

When building production applications on Base, raw Web3.py has limitations:

❌ **Repetitive boilerplate** - Every token balance needs 3+ RPC calls  
❌ **No retry logic** - Network errors crash your app  
❌ **No rate limiting** - Get blocked by RPC providers  
❌ **Manual optimization** - You implement caching yourself  
❌ **Base L2 complexity** - Manual L1+L2 fee calculations  

### The BasePy Solution

✅ **Smart batching** - Get entire portfolio in 2 RPC calls (vs 10+)  
✅ **Automatic retry** - Exponential backoff with circuit breaker  
✅ **Built-in rate limiting** - Never get blocked  
✅ **Intelligent caching** - 500x faster repeated queries  
✅ **Base L2 native** - L1+L2 fees calculated automatically  
✅ **Zero-cost features** - ERC-20 decoding from existing data

## 🏆 Performance Comparison

Real-world performance (Base Mainnet, December 2024):

| Task | BasePy SDK | Web3.py | Improvement |
|------|------------|---------|-------------|
| **Portfolio (ETH + 3 tokens)** | 2 RPC calls, 1.66s | 10+ RPC calls | **80% fewer calls** ✅ |
| **Decode ERC-20 transfers** | 0 additional RPC calls | 1+ RPC calls per token | **100% free** ✅ |
| **Token metadata (cached)** | <1ms response | 300-500ms | **500x faster** ✅ |
| **Multicall (4 operations)** | 1 RPC call | 4 sequential calls | **75% reduction** ✅ |

**Real Cost Impact:**  
For 1M portfolio checks at typical RPC pricing:
- Web3.py: ~$100 (10 calls × $0.01/1000)
- BasePy: ~$20 (2 calls × $0.01/1000)
- **You save: $80 per million requests (80% reduction)** 💰

## 🚀 Quick Start

### 30 Seconds to Your First Request

```python
from basepy import BaseClient

# Connect to Base Mainnet (or Sepolia testnet)
client = BaseClient()  # Mainnet
# client = BaseClient(chain_id=84532)  # Sepolia testnet

# Get complete portfolio (ETH + all common tokens)
portfolio = client.get_portfolio_balance("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1")

print(f"Wallet: {portfolio['address']}")
print(f"ETH: {portfolio['eth']['balance_formatted']:.6f}")
print(f"\nTokens with balance:")
for token_addr, info in portfolio['tokens'].items():
    if info['balance'] > 0:
        print(f"  {info['symbol']:6s}: {info['balance_formatted']:>12.6f}")
```

**Output:**
```
Wallet: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1
ETH: 1.234567

Tokens with balance:
  USDC  :  1000.500000
  DAI   :   250.000000
```

**RPC calls:** 2 (vs 10+ with Web3.py) 🎉

---

## 💎 Core Features

### 1. 🪙 Smart Portfolio Tracking

Get ETH + all token balances with minimal RPC calls:

```python
from basepy import BaseClient

client = BaseClient()

# Get portfolio with common Base tokens
portfolio = client.get_portfolio_balance(
    address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1",
    include_common_tokens=True  # USDC, DAI, WETH, etc.
)

# Or specify exact tokens
usdc = "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"
dai = "0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb"
portfolio = client.get_portfolio_balance(
    address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1",
    token_addresses=[usdc, dai]
)

print(f"Total assets: {portfolio['total_assets']}")
print(f"Tokens with balance: {portfolio['non_zero_tokens']}")
```

**Cost:** ~2 RPC calls (regardless of token count!) ⚡

---

### 2. 📊 Zero-Cost Transaction Analysis

Extract all ERC-20 transfers without additional RPC calls:

```python
from basepy import BaseClient, Transaction

client = BaseClient()
tx = Transaction(client)

# Get complete transaction details
details = tx.get_full_transaction_details(
    "0x123...",
    include_token_metadata=True
)

print(f"Status: {details['status']}")
print(f"ETH transferred: {details['eth_value_formatted']} ETH")
print(f"Token transfers: {details['transfer_count']}")

for transfer in details['token_transfers']:
    print(f"  {transfer['symbol']}: {transfer['amount_formatted']}")
```

**Advanced Analysis:**

```python
# Decode ALL ERC-20 transfers (zero cost!)
transfers = tx.decode_erc20_transfers("0x123...")

# Calculate balance changes for an address
changes = tx.get_balance_changes("0x123...", your_address)
print(f"ETH change: {changes['eth_change_formatted']:.6f} ETH")
for token, info in changes['token_changes'].items():
    print(f"{info['symbol']}: {info['change_formatted']}")

# Classify transaction type
classification = tx.classify_transaction("0x123...")
print(f"Type: {classification['type']}")  # 'swap', 'transfer', etc.
print(f"Complexity: {classification['complexity']}")
```

**Cost:** FREE - uses existing receipt data! 🎉

---

### 3. 💸 Send Transactions (Wallet Required)

Simple, production-ready transaction sending:

```python
from basepy import BaseClient, Wallet, Transaction

# Initialize with wallet
client = BaseClient()
wallet = Wallet.from_private_key("0xYourPrivateKey...", client=client)
tx = Transaction(client, wallet)

# Send ETH with automatic gas optimization
tx_hash = tx.send_eth(
    to_address="0xRecipient...",
    amount=0.1,  # 0.1 ETH
    gas_strategy='fast',  # 'slow', 'standard', 'fast', 'instant'
    wait_for_receipt=True  # Wait for confirmation
)
print(f"Sent! TX: {tx_hash}")

# Send ERC-20 tokens
from basepy.abis import ERC20_ABI

usdc = "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"
tx_hash = tx.send_erc20(
    token_address=usdc,
    to_address="0xRecipient...",
    amount=100 * 10**6,  # 100 USDC (6 decimals)
    abi=ERC20_ABI,
    gas_strategy='standard'
)
```

**Features:**
- ✅ Automatic gas estimation with buffer
- ✅ Nonce management with collision detection
- ✅ Transaction simulation before sending
- ✅ Automatic retry with exponential backoff
- ✅ Balance validation

---

### 4. ⚡ Batch & Multicall Operations

Execute multiple operations efficiently:

```python
# Batch get balances
addresses = ["0xAddr1...", "0xAddr2...", "0xAddr3..."]
balances = client.batch_get_balances(addresses)

# Multicall - Multiple contract calls in 1 RPC request
from basepy.abis import ERC20_ABI

usdc = "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"
calls = [
    {'contract': usdc, 'abi': ERC20_ABI, 'function': 'name'},
    {'contract': usdc, 'abi': ERC20_ABI, 'function': 'symbol'},
    {'contract': usdc, 'abi': ERC20_ABI, 'function': 'decimals'},
    {'contract': usdc, 'abi': ERC20_ABI, 'function': 'totalSupply'},
]
results = client.multicall(calls)
print(results)  # ['USD Coin', 'USDC', 6, 1234567890...]
```

**Cost:** 1 RPC call (vs 4 sequential calls) 🚀

---

### 5. ⛽ Base L2 Fee Calculation

Get complete transaction cost breakdown:

```python
# Estimate total cost (L1 + L2)
cost = client.estimate_total_fee({
    'from': wallet.address,
    'to': recipient,
    'value': 10**18,  # 1 ETH
    'data': '0x'
})

print(f"L2 execution cost: {cost['l2_fee_eth']:.6f} ETH")
print(f"L1 data cost: {cost['l1_fee_eth']:.6f} ETH")
print(f"Total cost: {cost['total_fee_eth']:.6f} ETH")

# Check if wallet can afford transaction
affordable = wallet.can_afford_transaction(
    to=recipient,
    value=0.1,
    buffer_percent=10
)
print(f"Can afford: {affordable}")
```

---

    client=client
)

# Export to keystore
wallet.to_keystore(
    password="secure-password",
    output_path="backup.json"
)

# Wallet operations with caching
balance = wallet.get_balance(use_cache=True)
nonce = wallet.get_nonce(use_cache=True)
portfolio = wallet.get_portfolio(use_cache=True)

# Sign messages (EIP-191)
signature = wallet.sign_message("Hello, Base!")

# Sign typed data (EIP-712)
typed_data = {...}
signature = wallet.sign_typed_data(typed_data)
```

### Code Comparison

**Get portfolio balance:**

```python
# ❌ Web3.py - Verbose, 10+ RPC calls
from web3 import Web3

w3 = Web3(Web3.HTTPProvider(rpc_url))
eth_balance = w3.eth.get_balance(address)

tokens_data = {}
for token in [usdc, dai, weth]:
    contract = w3.eth.contract(address=token, abi=ERC20_ABI)
    balance = contract.functions.balanceOf(address).call()  # Call 1
    symbol = contract.functions.symbol().call()            # Call 2
    decimals = contract.functions.decimals().call()        # Call 3
    tokens_data[token] = {'balance': balance, 'symbol': symbol, 'decimals': decimals}
# Total: 1 + (3 × N tokens) = 10+ calls for 3 tokens

# ✅ BasePy - Simple, 2 RPC calls
from basepy import BaseClient

client = BaseClient()
portfolio = client.get_portfolio_balance(address, [usdc, dai, weth])
# Total: 2 calls (1 for ETH, 1 multicall for all tokens)
```

**Decode token transfers:**

```python
# ❌ Web3.py - Manual, error-prone
receipt = w3.eth.get_transaction_receipt(tx_hash)
transfers = []
for log in receipt['logs']:
    if len(log['topics']) == 3 and log['topics'][0].hex() == TRANSFER_SIG:
        token = log['address']
        from_addr = '0x' + log['topics'][1].hex()[-40:]
        to_addr = '0x' + log['topics'][2].hex()[-40:]
        amount = int(log['data'].hex(), 16)
        transfers.append({'token': token, 'from': from_addr, 'to': to_addr, 'amount': amount})

# ✅ BasePy - Zero extra calls, automatic
from basepy import Transaction

tx = Transaction(client)
transfers = tx.decode_erc20_transfers(tx_hash)  # Done!
```
