The parity ledger reads wrapped supply and escrow balance at pinned blocks and records a ratio, with raw reads hashed.

The wrapped-asset parity ledger dated 2026-09-14 reads USDC.e on Arbitrum against the Arbitrum One ERC-20 gateway escrow on Ethereum. At Arbitrum block 504923416, totalSupply() on 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 returned 48,316,267.900248. At Ethereum block 25972488, balanceOf the escrow 0xcEe284F754E854890e311e3280b767F80797180d on the canonical USDC contract returned 52,223,762.917301. The ledger records escrow_over_wrapped as 1.080873, meaning the escrow balance read higher than the wrapped supply at those two blocks. Each raw hex return value is stored with its sha256, and each block carries its hash and a finality label: finalized tag as reported by the provider, not independently proven final. The ledger's attests field says what this is: point-in-time reads at the pinned blocks, a ratio, not a rate, not a grade, not a reserve attestation, not a certificate. The /wrappers/ page renders the same ledger.
