如何通过Web3.js或Web3.py获取BSC链上AA地址的全量交易（含Mint、Burn操作）

Got it, let's fix this. The BSCScan API's lack of support for non-transfer transactions like mint/burn is a real pain, but Web3.js and Web3.py give you the tools to pull all on-chain activity tied to your address. Here's how to do it step by step:

Method 1: Fetch All Transactions (Including Contract Interactions) #

This approach pulls every transaction where your address is either the sender (from) or recipient (to), then decodes the input data to identify mint/burn operations.

First, initialize your Web3 connection to a BSC node (we'll use Binance's public node here):

const Web3 = require('web3');
const web3 = new Web3('https://bsc-dataseed.binance.org/');

Next, write a function to fetch transactions across blocks (we batch 1000 blocks at a time to avoid hitting node limits):

async function getAllTransactions(targetAddress, startBlock = 0, endBlock = 'latest') {
  let allTxs = [];
  const finalEndBlock = endBlock === 'latest' ? await web3.eth.getBlockNumber() : endBlock;
  let currentBlock = finalEndBlock;

  while (currentBlock >= startBlock) {
    const batchEnd = currentBlock;
    const batchStart = Math.max(startBlock, currentBlock - 1000);

    // Loop through each block in the batch and pull relevant transactions
    for (let blockNum = batchStart; blockNum <= batchEnd; blockNum++) {
      try {
        const block = await web3.eth.getBlock(blockNum, true); // true = include full transaction details
        if (!block || !block.transactions) continue;

        // Filter transactions where target address is from or to
        const relevantTxs = block.transactions.filter(tx => 
          tx.from.toLowerCase() === targetAddress.toLowerCase() || 
          (tx.to && tx.to.toLowerCase() === targetAddress.toLowerCase())
        );
        allTxs.push(...relevantTxs);
      } catch (err) {
        console.log(`Skipping block ${blockNum}: ${err.message}`);
      }
    }

    currentBlock = batchStart - 1;
  }

  return allTxs;
}

Now, call this function and decode transaction inputs to spot mint/burn operations. You'll need the ABI of the contracts your address interacts with (grab this from BSCScan's contract page):

// Replace with your target address and contract ABI
const targetAddr = '0xYourAAAddressHere';
const erc20ABI = [/* Paste your contract's ABI here */];

getAllTransactions(targetAddr).then(txs => {
  txs.forEach(tx => {
    // Skip empty input (simple ETH/BNB transfers)
    if (tx.input === '0x') return;

    try {
      const contract = new web3.eth.Contract(erc20ABI, tx.to);
      const decoded = contract.decodeFunctionData(tx.input);
      
      console.log(`Tx ${tx.hash}: ${decoded.methodName} operation`);
      if (decoded.methodName === 'mint' || decoded.methodName === 'burn') {
        console.log(`✅ Found ${decoded.methodName} transaction: ${tx.hash}`);
      }
    } catch (err) {
      // Handle non-standard contracts or unknown methods
      console.log(`Could not decode tx ${tx.hash}: ${err.message}`);
    }
  });
});

Method 2: Listen for Transfer Events (Mint/Burn Proxy) #

Most mint operations emit a Transfer event from the zero address (0x0000000000000000000000000000000000000000) to your address, while burns emit a Transfer from your address to the zero address. You can directly fetch these events:

async function fetchMintBurnEvents(targetAddr) {
  const transferEventABI = [
    {"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"from","type":"address"},{"indexed":true,"internalType":"address","name":"to","type":"address"},{"indexed":false,"internalType":"uint256","name":"value","type":"uint256"}],"name":"Transfer","type":"event"}
  ];

  // Replace with the contract address you care about (e.g., the token contract)
  const contractAddr = '0xB8c77482e45F1F44dE1745F52C74426C631bDD52';
  const contract = new web3.eth.Contract(transferEventABI, contractAddr);

  // Fetch mint events (from zero address to target)
  const mintEvents = await contract.getPastEvents('Transfer', {
    fromBlock: 0,
    toBlock: 'latest',
    filter: { from: '0x0000000000000000000000000000000000000000', to: targetAddr }
  });
  console.log('Mint Events:', mintEvents);

  // Fetch burn events (from target to zero address)
  const burnEvents = await contract.getPastEvents('Transfer', {
    fromBlock: 0,
    toBlock: 'latest',
    filter: { from: targetAddr, to: '0x0000000000000000000000000000000000000000' }
  });
  console.log('Burn Events:', burnEvents);
}

// Call the function
fetchMintBurnEvents(targetAddr);

Method 1: Fetch & Decode All Transactions #

Similar to the Web3.js approach, we'll pull relevant transactions and decode inputs to identify mint/burn operations.

First, set up your Web3 connection:

from web3 import Web3

# Connect to BSC public node
w3 = Web3(Web3.HTTPProvider('https://bsc-dataseed.binance.org/'))

Write a function to fetch transactions across blocks:

def get_all_transactions(target_address, start_block=0, end_block='latest'):
    all_txs = []
    final_end_block = w3.eth.block_number if end_block == 'latest' else end_block
    current_block = final_end_block

    while current_block >= start_block:
        batch_end = current_block
        batch_start = max(start_block, current_block - 1000)

        for block_num in range(batch_start, batch_end + 1):
            try:
                block = w3.eth.get_block(block_num, full_transactions=True)
                if not block or not block.transactions:
                    continue

                # Filter transactions involving target address
                relevant_txs = [
                    tx for tx in block.transactions
                    if tx['from'].lower() == target_address.lower()
                    or (tx['to'] is not None and tx['to'].lower() == target_address.lower())
                ]
                all_txs.extend(relevant_txs)
            except Exception as e:
                print(f"Skipping block {block_num}: {str(e)}")

        current_block = batch_start - 1

    return all_txs

Decode transactions to find mint/burn operations (again, use the contract's ABI from BSCScan):

target_addr = '0xYourAAAddressHere'
erc20_abi = [
    # Paste your contract's ABI here (include mint/burn functions and Transfer event)
    {
        "inputs": [{"internalType": "address", "name": "to", "type": "address"}, {"internalType": "uint256", "name": "amount", "type": "uint256"}],
        "name": "mint",
        "outputs": [],
        "stateMutability": "nonpayable",
        "type": "function"
    },
    {
        "inputs": [{"internalType": "uint256", "name": "amount", "type": "uint256"}],
        "name": "burn",
        "outputs": [],
        "stateMutability": "nonpayable",
        "type": "function"
    }
]

all_txs = get_all_transactions(target_addr)

for tx in all_txs:
    if tx['input'] == '0x':
        continue

    try:
        contract = w3.eth.contract(address=tx['to'], abi=erc20_abi)
        func, params = contract.decode_function_input(tx['input'])
        
        print(f"Tx {tx['hash'].hex()}: {func.fn_name} operation")
        if func.fn_name in ['mint', 'burn']:
            print(f"✅ Found {func.fn_name} transaction: {tx['hash'].hex()}")
    except Exception as e:
        print(f"Could not decode tx {tx['hash'].hex()}: {str(e)}")

Method 2: Fetch Mint/Burn via Transfer Events #

Use the same zero-address trick to pull mint/burn events directly:

def fetch_mint_burn_events(target_addr):
    transfer_event_abi = [
        {"anonymous":False,"inputs":[{"indexed":True,"internalType":"address","name":"from","type":"address"},{"indexed":True,"internalType":"address","name":"to","type":"address"},{"indexed":False,"internalType":"uint256","name":"value","type":"uint256"}],"name":"Transfer","type":"event"}
    ]

    # Replace with your target contract address
    contract_addr = '0xB8c77482e45F1F44dE1745F52C74426C631bDD52'
    contract = w3.eth.contract(address=contract_addr, abi=transfer_event_abi)

    # Fetch mint events
    mint_events = contract.events.Transfer.get_logs(
        fromBlock=0,
        toBlock='latest',
        argument_filters={'from': '0x0000000000000000000000000000000000000000', 'to': target_addr}
    )
    print("Mint Events:", mint_events)

    # Fetch burn events
    burn_events = contract.events.Transfer.get_logs(
        fromBlock=0,
        toBlock='latest',
        argument_filters={'from': target_addr, 'to': '0x0000000000000000000000000000000000000000'}
    )
    print("Burn Events:", burn_events)

# Call the function
fetch_mint_burn_events(target_addr)

Key Notes #

• Node Limits: Public BSC nodes may throttle your requests. Add delays between batch calls, or use a paid node service for faster, more reliable access.
• ABI Requirements: You need the contract's ABI to decode transactions/events. Grab this from BSCScan's contract page under "Contract ABI".
• Non-Standard Contracts: Some tokens use custom mint/burn functions or events. If the above methods don't catch them, check the contract's source code to find the correct function signatures or event definitions.
• Efficiency: Querying from block 0 will take a long time. Instead, track the last block you queried and only pull new blocks going forward.
