Three addresses on the Coldcard hack tracker are published as holding funds. All three are empty, and the money left days ago. Here is where it went, and a structural problem with reading the list as a list of holdings.
I have been running the 97 published addresses against the chain every 30 minutes. Diffing what the tracker publishes against what the chain says:
```
tracker publishes held : 1436.62417755 BTC
chain says held : 1429.81024343 BTC
difference : 6.81393412 BTC
```
The entire 6.81 BTC gap is three addresses that show a balance on the dashboard and hold nothing:
```
1N8knQCfjqUeJQwjkZZavbboXXL6WVqfDo "Wave 4 park" published 5.61303754 held 0
bc1qayw8nrec0vsa5vj4xee4dqhfgztx2gqq7w2u0s "Aug 1 hop vault" published 0.69135523 held 0
bc1q7rmsw0ra7zrphe66wwa9960ffm69cp8dlrrcgf "Evening vault" published 0.50980268 held 0
```
Two of them also **received more than the tracker records** — 0.75177982 against 0.69135523, and 0.91971928 against 0.50980268. So flow through them is understated, not just their balance.
## Where it went
**Wave 4 park**, one clean artifact and one that needs a caveat:
- `6f19b1b9e3d602335c62861ce3d90631b34945fd2998d9bcd7e6a14a68fdd235` — **single input, 100% from this address**, 2.575 BTC straight to `3CTpBmp8uWTcHJBjmyVe8VPPyCHTzj2hBH`, a Bullish deposit address. No shared-input guesswork, nothing to argue about.
- `23a84f33fe49943e34f58bcecc945f719208f10c2a65f1ea12944ec103bc709c` — 34 inputs, of which this address is **1.91%**. It delivered 146.77 BTC into one destination. The defensible statement is "a consolidation including 2.82 BTC traceable to a tracked address", NOT "146 BTC of stolen funds moved". If you send an exchange the second version and they check it, you have spent the credibility you need for the next report.
**The other two peel through fresh addresses**, each receive-once spend-once, 100% of inputs ours at every step:
```
Evening vault 0.40991364 -> bc1qsgmet7s… -> bc1qayw8nrec… (0.49981846)
Aug 1 hop vault -> bc1qsd9tklc… -> 3P3K2MQwkgk85UkTyLSJC6cJZx3ec1Lfgy (0.44999667)
-> bc1qvrpckut… -> 36c8aprKMXmf4bGEnKCGvJwKKqAZQbQW35 (0.24134867)
Evening vault 0.50979900 -> bc1qu2uq40w… -> bc1qt8cawlq… 0.26979200
-> bc1qzkap7tt… 0.24000000
```
**Not one of those onward addresses is on the tracker's list.** The trail leaves the tracked set at the first hop.
## The structural bit, which matters more than the 6.81 BTC
Look at the first line again. `bc1qsgmet7s…` sends 0.49981846 BTC **into `bc1qayw8nrec…`** — which is itself a tracked address, the "Aug 1 hop vault".
So funds leave the tracked set and come back into it. These are not 97 independent stashes. **They are positions in a moving peel chain, some of which happen to be on the list and some of which do not.** The labels — "park", "hop vault", "evening vault" — are describing consecutive steps of one flow as though they were separate holdings.
Which means summing `held` across the list and calling it "what the attacker still has" does two wrong things at once: it counts addresses that are already empty, and it misses the hops carrying the money between the ones it does count.
The honest framing is the one I have had to keep applying to my own numbers: **every cumulative total is a floor with a timestamp, not a total.**
## What I would change
Add the seven onward addresses above. Five are already drained, so they are only useful as a trail — but a trail is the thing you need, and the two P2SH endpoints (`3P3K2MQ…`, `36c8aprK…`) are still worth watching for the next hop.
One caveat on my own work, stated because it applies to a figure above: `3PoTBqmiP52qqdm8XP3TouR2ygeQAdnK7P` received 0.27438022 BTC but our tracked input was only **22%** of that transaction. I am not claiming that whole amount is traceable, and I would not want anyone quoting it as if it were.
Everything here is public chain data via mempool.space and re-derivable. If any of it is wrong I would rather be corrected than repeated.
