This post covers the primitive itself, the two interfaces with real Solidity, a minimal borrower, the security model behind the odd-looking magic return value, and the honest adoption picture.</p> https://blazed.sh/blog/posts/flash-loan-arbitrage/ Wed, 22 Jul 2026 08:33:00 +0000 https://blazed.sh/blog/posts/flash-loan-arbitrage/ <h2 id="arbitrage-without-capital">Arbitrage Without Capital</h2> <p>In the earlier posts of this series we covered how to <em>find</em> arbitrage: <a href="https://blazed.sh/blog/posts/tri_arbitrage">triangular arbitrage on Uniswap</a> for the three-pair case, and <a href="https://blazed.sh/blog/posts/graph_theory_arbitrage">graph-based detection with Bellman-Ford</a> for cycles of any length. Both posts quietly assumed you already hold the tokens you want to trade with. That assumption is the biggest practical barrier to arbitrage: a 0.5% spread on a 10 ETH trade pays 0.05 ETH, and scaling it means parking serious capital in hot wallets.</p>
