AI-Generated Review

What is lighthouse-router?

Lighthouse-router is a Rust crate for off-chain DEX route discovery on Solana, pulling pool data via RPC to enable multi-hop quoting and arbitrage cycle detection. It decodes pools from Raydium AMM v4, Orca Whirlpools, and Phoenix order books, then builds token graphs for finding optimal swap routes or profitable cycles without on-chain execution. Developers get a lightweight library and CLI for quick quotes like `lighthouse quote --from USDC --to SOL --amount 1e9 --max-hops 3`.

Why is it gaining traction?

Unlike bloated aggregators like Jupiter, it's dependency-light and predictable—no cross-program calls, MEV bundles, or slippage protection, just honest off-chain primitives you control. The CLI and simple API shine for rapid prototyping, while Bellman-Ford cycle detection spots arb opportunities at marginal sizes. Rust's speed keeps route searches fast even on dense graphs.

Who should use this?

Solana traders scripting custom off-chain DEX routers for better quotes than single-venue swaps. Arbitrage hunters scanning for negative cycles across venues. Backend devs at trading bots or aggregators needing pool quoting without third-party APIs.

Verdict

Grab it if you need lean Solana DEX discovery tools—core quoting and routing are stable with solid tests—but skip for production swaps (1.0% credibility score reflects 45 stars and early status). Docs and examples make it dead simple to start.
