Stablecoin Cemetery
Every stablecoin in this list lost its peg permanently or was abandoned by its issuer. We surface them not as a museum exhibit but as a pattern library: each failure mode below is still present — dormant or active — in stables currently in circulation. If you hold a vault denominated in an algorithmically-backed stable, UST is its dead cousin. If you hold a CeFi stable, HUSD is the cautionary tale.
