built a fully autonomous MEV arbitrage bot on Arbitrum in 5 days. zero capital at risk. it borrows money, executes the trade, repays the loan, and keeps the profit -- all in one atomic transaction. if the math doesn't work, it reverts like it never happened. the numbers: > AMM price calculation: 17 ns > profit threshold check: 21 ns > trade encoding: 133 ns > full market scan (100 pools): 467 µs for context on how fast that actually is: > a human blink: 150,000,000 ns > Uniswap v3 TypeScript SDK: 200,000 - 500,000 ns per quote > typical Python MEV bot: 50,000 - 500,000 ns per operation > arbx AMM calculation: 17 ns so basically, the bot evaluates an entire arbitrage opportunity and decides whether to execute, in less time than light travels 1 meter. that's not an optimization. that's a different class of software. test coverage: > 23 fork tests against real Arbitrum state > fuzz, invariant, chaos, and property tests (10k iterations each) > every benchmark beat its target. some by 750x. the best part? not a single line written by me. every line is written single-handedly by Claude Sonnet 4.6 only the architecture, design, system thinking was done by me (and some Claude obv) i have officially become the vibecoding final boss >:) repo in comments.
