Multi-Chain Automation & Interoperability Toolkit 🌐

A production-grade collection of Python scripts designed for advanced interaction, security, and automation across multiple blockchain architectures.

This toolkit goes beyond standard RPC calls, implementing low-level transaction signing, hybrid Web2/Web3 authentication, and cross-chain interoperability mechanisms.

📂 Architecture & Modules

1. 🛡️ Security & Mempool Defense

Located in /security

• Defensive Front-Runner: Real-time mempool monitoring via WebSocket. Detects malicious transactions targeting specific wallets and automatically broadcasts a defensive cancellation transaction (higher gas price) to prevent hacks or unauthorized drains.

2. 💧 Advanced DeFi & Liquidity

Located in /liquidity

• Monad Token Swapper (EIP-2612): Implements Gasless Approvals (Permit) with offline signing (EIP-712). Features a fallback mechanism to standard approve if the token lacks permit support.
• Ronin Validator Exit: Automated unstaking bot that monitors validator epochs using estimateGas polling and sweeps funds to a cold wallet immediately upon release.
• Pharos Liquidity Provider: EIP-1559 compatible script for managing liquidity pools with pre-flight simulation (eth_call) and reverting error decoding.

3. ⚡ MEV & Block Strategies

Located in /mev_strategies

• Chiliz Time-Locked Sniper: A block-synchronized bot that monitors chain height to execute claims exactly at a specific block number. Uses state-change detection (balance monitoring) to ensure execution success.

4. 🔗 Interoperability (Non-EVM)

Located in /interoperability

• Cosmos (ATOM) Protobuf Signer: Bypasses high-level CLI tools to construct, serialize, and sign transactions using Google Protobuf and secp256k1 primitives directly.
• Polkadot (DOT) Sweeper: Interacts with the Substrate runtime to calculate precise fees and execute transfer_allow_death, allowing for complete account reaping (cleaning dust).

5. 🤖 Hybrid Interaction (Reverse Engineering)

Located in /interaction

• Hybrid Minter Bot: Demonstrates a Web2/Web3 bridge. Authenticates via JWT with a centralized API, retrieves a server-side cryptographic signature, and constructs a raw EVM transaction (bypassing ABI) to mint assets on-chain.

🛠️ Technical Highlights

• Raw Transaction Construction: Manual encoding of calldata and RLP serialization without relying on full contract ABIs.
• Gas Optimization: Dynamic fee estimation supporting both Legacy and EIP-1559 standards.
• Cryptography: Implementation of EIP-712 (Typed Data) and Protobuf serialization.
• Concurrency: Usage of threading and asyncio patterns for high-frequency polling.
• Safety: Pre-flight simulations and strict nonce management to prevent stuck transactions.
