staked 2,524,680.76 AVAX on 1 Jan 2026, exported 2,534,260.22 AVAX at 00:08:02 UTC on 30 Jun 2026, and had 2,500,060 AVAX on NodeID-DVh35F3R11HAAxzeSTbk3eR9w2BzPrJQt to 25 Sep 2026 00:00:00 UTC at the 16 Sep read. AVAT's BitGo-era key P-avax1r2jcftp ran five validation periods on that same full node ID between 3 Nov 2025 and 15 Apr 2026, the third node shared with the trail after NodeID-Cgdu1Ghr and NodeID-F5Ecwd5q. Nodes are rented and serve many customers, so a shared node corroborates and does not prove
Evidence: scratch/hunt/blue/custody-batch.md: a walk of 10,670 P-Chain blocks with platform.getBlockByHeight over three windows found nine AddPermissionlessValidatorTx of 100,000 AVAX or more in the 1 Jan 2026 re-stake window sharing one fingerprint: a 100 percent delegation fee, a threshold-1 reward owner equal to the staking key, and an end at an exact month-end 00:00:00 UTC. Three walks of the same 68,196 blocks by two sessions return those nine and no tenth. The cluster is now matched to filed quantities at three dates by that one method: the nine stakes sum to 8,284,248.39 AVAX against the 8,329,871 AVAX filed at Coinbase Custody at 31 Dec 2025, which is 99.452 percent; 8,416,336.28 AVAX against the 8,462,227 AVAX in the 424B3 at 31 Mar 2026, which is 99.458 percent; and six of the nine exported to the C-Chain between 00:08:02 and 00:09:05 UTC on 30 Jun 2026 summing 4,458,518.01 AVAX against the 4,510,207 AVAX filed at 30 Jun 2026, which is 98.854 percent. On the refined fourteen-wallet set, read as C-Chain balances at the filed instant itself, the two testable dates read 99.9878 percent (gap 1,015.83 AVAX) and 99.9779 percent (gap 996.01 AVAX). The cluster is matched to the filed quantity at three dates as a set, which is an inference and not a proof: the tie to this key is collective and arithmetic, not a flow, and no member is pinned on its own. The June 98.854 percent is a subset-sum fit from a 63-second export window, which cannot see a stake that spans the filed instant; at least four fingerprint keys held 1,647,622 AVAX across 30 Jun 2026 and are excluded by quantity alone (scratch/hunt/blue2/SEARCHES-2.md sections 2.1 and 2.2, from tenth-member.md and batch-counterparts.md). Re-run: POST https://avalanche-p-chain-rpc.publicnode.com platform.getBlockByHeight across 23:30 to 01:30 UTC around each month end, then GET https://data-api.avax.network/v1/networks/mainnet/blockchains/p-chain/transactions?addresses={key}&pageSize=100 (glacier-api.avax.network answers 429 to unkeyed callers; data-api serves the same routes). The eight-character node prefix the merge held back was confirmed on 16 Sep 2026 from both sides. POST https://avalanche-p-chain-rpc.publicnode.com platform.getCurrentValidators with nodeIDs NodeID-DVh35F3R11HAAxzeSTbk3eR9w2BzPrJQt returns this key as the threshold-1 reward owner of 2,500,060.1177 AVAX ending 2026-09-25 00:00:00 UTC, and GET https://data-api.avax.network/v1/networks/mainnet/blockchains/p-chain/transactions?addresses=P-avax1r2jcftpt0tz6l0wlx4qsc8jqd90kvk7hy997qp&pageSize=100 returns 39 transactions across eleven node IDs, five of them validation periods on that same full node ID between 2025-11-03 22:21:51 and 2026-04-15 16:48:17 UTC. The Glacier host answers 429 for unkeyed callers; data-api.avax.network serves the same route. Node continuity, evidence class D, is weak on its own here and the row does not rest on it. MEASURED: one private key unrelated to either company, P-avax1qtrykwgqkpj8c9wl93cymu6q9ffssyyu95q8wp, has delegated to NodeID-DVh35F3R11HAAxzeSTbk3eR9w2BzPrJQt since 2022-01-01 21:17:23 and to NodeID-3kUUeZB7umtaENekUfWxa1bxrAU2eq1AD since 2021-09-29 20:48:15, years before Avalanche Treasury Corp existed, and its automation re-delegated 130,455.60 AVAX twice on 2026-08-06 at a 100 percent fee that pays it nothing. These are rented commercial validators, so any node must be age-checked before its overlap is printed as corroboration (scratch/hunt/blue2/delegator-sweep.md section 5). The same read withdraws the claim that a 100 percent fee means no third party can delegate: that node reports delegatorCount 2 and delegatorWeight 260,911.20 AVAX. Re-run: POST https://avalanche-p-chain-rpc.publicnode.com platform.getCurrentValidators with the nodeID, then platform.getTx on the delegation's consumed UTXOs back through the key's own history. Its C-Chain counterpart is 0x1c90D5440c0E768CF7Ed984770E0D51A6fe8E417 (scratch/hunt/blue2/batch-counterparts.md section 1).

- What would promote it
- met three ways on two chains, and the row still does not stand alone. The December departure the condition asked for is ExportTx in P-Chain block 23,988,236 at 2025-12-31 00:52:05 UTC for 2,524,680.8611 AVAX, threshold 1 to the C-Chain; the C-Chain ImportTx is block 74,763,695 at 00:55:04 for 2,524,680.7611; and eth_getBalance on the counterpart 0x1c90D544 at block 74,824,633 returns the identical figure, so the money sat on the C-Chain through the filed instant. No individual batch key is pinned on its own, so the cluster's collective grade stands
- What would kill it
- a tenth fingerprint-matching stake of real size in the un-walked hours of 1 Jan 2026, or the C-Chain counterpart failing the two block tests
