Orca
Solana concentrated-liquidity AMM (Whirlpools) with open-source TypeScript and Rust SDKs.
Last release Aug 10, 2026 · Last commit Aug 28, 2026 · ★ 539
Overview
Orca is a concentrated-liquidity automated-market-maker spot DEX on Solana (and Eclipse), centered on its open-source Whirlpools program. It provides high-level TypeScript (@orca-so/whirlpools) and Rust SDKs for swaps, liquidity, and position management, which bots and Solana agents can use to trade and manage pools programmatically. Performance and safety are not verified here.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
Last 30 days — to 2026-09-09, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
