Custody, as observed on-chain
Of the 111,267 ETH in the 13 addresses read, 100% is spent by a single key (indistinguishable from MPC on-chain), 0% through a multisig script, and 0% has never spent, so its control is not yet visible.
| What spends it | Addresses | Balance |
|---|---|---|
| One key (or an MPC wallet, which looks the same on-chain) | 13 | 111,267 ETH |
Read from 13 of 13 published addresses, holding 111,267 ETH, on 2026-09-30.
Repeated nonces
168 signatures from 13 keys across 13 addresses were checked and no nonce was repeated. For 5 busy addresses only the most recent transactions were read.
What it would take to move the exposed balance
