Fail closed: why our screener says "review" when a source is down
A compliance check that fails open is worse than none at all.
Most outages are quiet. An RPC node times out, or a list download fails. If the screening code treats "no answer" as "no problem", a sanctioned wallet can slip through on a bad day.
Our rule
Clear only says allow when every source answered and none matched. If any source is unavailable, the answer is review. Payouts don't move on review.
Test it yourself
Any address containing BLOCKED, SANCTION or OFAC is a sandbox test and always returns deny. That lets developers check their integration handles a real decline before going live.
