Freysa is a series of adversarial agent experiments: an AI agent controls a prize pool onchain and users pay to send messages attempting to persuade it to transfer the funds. It became a notable case study in agent security, prompt-injection resistance, and autonomous custody of funds.

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.

State changed on 2026-09-29 (responding → unreachable from our probe), 2026-09-30 (unreachable from our probe → responding), 2026-10-14 (responding → unreachable from our probe), 2026-10-15 (unreachable from our probe → responding).
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.
