Two Publishers, One Shared Failure

Pragma’s Vesu post-mortem explains how apparent price diversity collapsed into one shared dependency.

A stale route through an inactive USDC.e pool produced a bad USDT/USD observation. Freshness filtering left only that value and one healthy exchange price. The resulting aggregate was then reused to construct other feeds, making several major assets appear to lose about half their value.

Two publishers did not provide two independent answers. They ran the same software and repeated the same conversion path. Vesu saw healthy-looking source counts on the composed feeds even though those observations depended on one weak input.

For BYKO, several wallets and price pages showing the same number are not independent confirmation if they inherit the same pool, API or conversion chain. Surface count is not source independence.

The technical account comes from Pragma. Independent reports confirm the liquidations, but have not yet reproduced the full root cause.
