member - the C-Chain counterpart of P-avax1xpedzqexwkzjhuj4dp5dcmc0nvphvwld2mkcwa, which held 2,524,680.7611 AVAX at block 74,824,633 (2025-12-31 23:59:56 UTC), 2,534,260.1177 AVAX at block 89,166,730 (2026-06-30 23:59:59 UTC) and 0 today. Its first atomic row is an ExportTx of 2,500,000.2060 AVAX at 13:22:04 UTC on 28 Oct 2025, and it took the 31 Dec 2025 ImportTx of 2,524,680.7611 AVAX in block 74,763,695 at 00:55:04, three minutes after the P-Chain export in block 23,988,236. The only money it ever took from outside the family is two atomic rows on 21 Oct 2025, 0.1 AVAX and 3,658,982.70 AVAX, each of which is its own row here
Evidence: scratch/hunt/blue2/batch-counterparts.md sections 1 and 2, re-measured in batch-counterparts-VERIFY.md. Class A inside the family and class C at the filed dates. The counterpart was found through the key's own complete atomic history, 9 or 10 rows with nextPageToken null: every ExportTx carries one evmInputs[0].fromAddress and every ImportTx one evmOutputs[0].address, and across all 56 rows of the six keys that address is one and the same per key. Balances were then read at the two filed blocks, so these are balances at the filed instant rather than stakes read a day later or exports read 24 hours early. The six vaults sum to 4,937,039.894 AVAX at block 74,824,633 and 4,458,517.412 AVAX at block 89,166,730; with the five cold wallets and the three payees the vaults themselves paid, fourteen wallets sum to 8,328,855.165 AVAX at 31 Dec 2025, which is 99.9878 per cent of the filed 8,329,871, and 4,509,210.995 AVAX at 30 Jun 2026, which is 99.9779 per cent of the filed 4,510,207. The grade is capped at 0.80: these vaults pay a wallet that pays 0x8de2cf20, so they sit one hop further from the treasury than a wallet the registry already grades 0.80 inferred.

How this row was graded
- Evidence class
- A, flow tie
- Confidence
- 0.80 on a scale of 0 to 1
- Customer
- AVAT
- What would promote it
- an outflow from it into a wallet the registry grades proven for AVAT with no omnibus between, or a filed quantity matching this one vault's balance to the unit
- What would kill it
- it paying a wallet tied to another named entity, or a balance at a fourth filed date contradicting its export amount
