PLIM-A

Plimsoll Note Series A. The negative control. It must always refuse, and a clean result on the other note is worth nothing without it.

No figure

Outstanding
$1,000,000.00

10,000.00 notes at $100.00, read from the note

UnprovenThe oracle holds no attestation for this note, so there is nothing to read a figure from.

NoAttestation

CoverageOracle holds no attestation for PLIM-A: the attestor read its position live and refused it as coverage_below_floor, so there was nothing to submit.

What the note owes

  • totalSupply()1,000,000 base units
  • decimals()2
  • Notes outstanding10,000.00
  • getNominalValue()$100.00 a note
  • Obligation$1,000,000.00

The denominator of every ratio on this screen is read from the note itself — supply times nominal value — and never taken from configuration.

Backing by vault

Held on Base by the issuer's own address. The vault set is registered on CoverageOracle, and the two notes’ sets are disjoint: a position backs exactly one note. Read from each vault at Base block 51,243,788, 2026-09-13 05:22:03 UTC: 1.000000 USDC, which is 0.00% of the $1,000,000.00 the note owes. That is a reading of the positions, not an attestation: the oracle holds a figure only while a signed attestation is fresh, and without one the venue refuses.

The line, and who moved it

  • Threshold100.00%
  • Listingnot listedThe negative control is never meant to clear: a $1,000,000 obligation against one dollar of backing.

  • Record 23Refused · 0.00%$15.00 against $1,000,000.00, computed from fixture backing (fixture:plimsoll-base-backing-v0) against the vault set that has since been replaced. It proves the path on this note, not this note’s backing.

A figure from fixture backing is never shown as this note’s coverage, and a lapsed attestation counts for nothing: the venue trades on a fresh one or not at all.
