Claim this listing →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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

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. 37 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. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-24, 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.
