Sift Join the waitlist

AI triage for Solidity audits

Kill the false positives. Ship the real fixes.

Sift runs your scanners, then judges every finding. Review the five that matter, not the five hundred that do not.

Timestamp gates a 7 day window. Sub-15s drift cannot affect it. False positive.

Excerpt from reports/triage.md

Scanners find everything. That is the problem.

Slither and Aderyn flag hundreds of issues per run. Most are not bugs. After the first dozen false alarms, engineers stop reading the report, and the one finding that mattered ships to mainnet.

9 in 10

static-analysis findings are false positives. Triage is where audit time actually goes.

How Sift works

Four steps. The scanners stay free and open source. The intelligence is the part you pay for.

Scan

Run the tools you already trust. Sift drives Slither and Aderyn and collects their output.

make audit

Fingerprint

Every finding gets a content hash that survives line shifts and reformatting, so nothing is ever triaged twice.

detector + file + function + code

Triage

An open-weights model trained on audited contracts returns a verdict, a confidence score, an exploit path, and a fix.

verdict: true_positive conf 0.94

Remember

Verdicts persist in a ledger you commit to your repo. Confirm a false positive once and it stays suppressed until the code changes.
