Construct evm-based sandwich attacks using Rust and Huff.
subway-rs is a port of libevm's original subway, implemented with ethers-rs and huff.
Having highly optimized contracts is just one part of the equation, a tech stack is just as important as the contracts to execute on the opportunities. Source: libevm/subway
If having a tech stack is just as important as optimized, secure contracts, then why not use the best language available for speed, dependability, and scalability? This is the sandwich-rs bot: A pure-rust bot used to execute sandwich attacks on UniswapV2. The bot's goal is to act as a low barrier of entry for rust-based MEV development - Reference source code for aspiring new searchers.
It's fast. But don't take our word for it, just check out the benchmarks.
Current abilities:
- Watch pending transactions in the mempool.
- Decode Transaction data for Uniswap V2 Calls. (and more soon!)
- Verbose telemetry reporting using tracing.
- Search for profitable strategies efficiently using a variety of algorithms.
- Calculate gas bribes.
- Simulate and Execute Flashbot Bundles.
Although the bot functions, it is simplistic and certainly not competitive. Accept that advanced searchers to already be executing far beyond the current capabilities. That being said, below is a non-exhaustive list of low hanging fruit to further subway-rs along.
- Deployment logic for contracts
- Circuit Breakers
- Alerting (see: https://github.com/DeGatchi/mev-template-rs)
- Poision Token Filtering
- Caching + Memoization
- Enhanced Logging Filters
- Zero-cost Gas Savings 👀
- Real-time Benchmarking
- Improved Parallelization
- Persistent Execution Storage and Tracking (eg: psql, a rekt threshold, P&L)
- Refactored Wallet Management
Again, please be aware, this bot is intended as a piece of educational content, and not for production use. It has not been run in production, and should not be used in such an environment.
