RESEARCH: Smart contract exploits, DeFi hacks, and crypto security breaches in the last 7 days. For each: protocol, chai

As a large language model, I do not have real-time, live access to constantly updating blockchain security feeds or financial databases, which is required to pull a definitive list of all hacks over the last 7 days. Crypto security breaches are highly volatile, and accurate data requires dedicated, real-time scraping from sources like Blocknative, specialized DeFi intelligence firms, or major crypto news aggregators.

Therefore, I cannot provide the actual, definitive JSON array for the last 7 days.

However, I can provide the structure you requested and explain where you would need to query this data to fulfill your research needs. If I were to receive this data from a live API, the output would look exactly like this example structure:

⚠️ Important Disclaimer

The data provided below is illustrative and fictional. It is structured to match your request but does not reflect actual events from the last 7 days. You must use real-time blockchain security trackers for actionable intelligence.

Structured JSON Array Example

[
  {
    "protocol": "Example Lending Platform V2",
    "chain": "Ethereum (ETH)",
    "amountLost": "$3,250,000",
    "rootCause": "Flash loan vulnerability allowing recursive manipulation of collateral ratio (Re-entrancy style exploit).",
    "date": "YYYY-MM-DD"
  },
  {
    "protocol": "Mega Yield Farm DAO",
    "chain": "Solana (SOL)",
    "amountLost": "$1,890,000",
    "rootCause": "Insecure implementation of governance contract allowing unauthorized withdrawal of funds via improper role permissioning.",
    "date": "YYYY-MM-DD"
  },
  {
    "protocol": "Interchain Bridge XY",
    "chain": "Optimism (OP)",
    "amountLost": "$1,120,000",
    "rootCause": "Integer overflow exploit during token minting/locking process on the bridge contract.",

Recommended Sources for Real-Time Data

To perform this research effectively, I strongly recommend checking the following sources, as they aggregate this real-time security data:

1. Messari/Crunchbase: For comprehensive market analysis and listing recent high-profile hacks.
2. DeFi Intelligence Firms (e.g., Delphi Digital): These specialized firms often report incidents immediately after they happen.
3. Blockchain Explorers (Etherscan, Solscan): By filtering for large outgoing transfers from known protocol contract addresses, you can manually track suspicious activity.
4. Crypto News Aggregators (e.g., Cointelegraph, CoinDesk): These sources usually report major hacks within hours.
