Watch one lookalike payment fail.
Every number and status on this page is read live when you open it: evidence from Arkiv, the demo Safe and its Guard from Sepolia, and the recorded payments' receipts. The verdicts are computed in your browser.
Part 1 is real Ethereum mainnet evidence, status suspected. Parts 2–5 are a synthetic re-enactment on Sepolia with addresses we generated, not a real attack.

Step 1 · Ethereum mainnet · read from Arkiv
Poisoning is happening on Ethereum.
The HexFence detector publishes suspected address-poisoning records to Arkiv. Here is what its publisher holds right now, and the latest record it found.

Step 2 · the trick
Same start, same end, different address.
Our demo Safe pays one approved supplier, P. We generated L to share P's first 4 and last 4 characters. In a transaction history, that is often all anyone reads.

Step 3 · Sepolia · read from the chain
The Safe and its Guard.
The demo Safe's active guard and its approved payees, read once in bulk from Sepolia. This page reads directly, not through Nox; HexFence Pay uses Nox.

Step 4 · in your browser
Before you sign: three verdicts.
The same verdict logic HexFence Pay uses, run here on the payees from step 3. Nothing about these recipients is sent anywhere.
Waiting for the approved payees…

Step 5 · Sepolia · recorded payments
At execution: the Guard decides.
These payments were sent from the demo Safe by a script wallet, not by a person in Safe{Wallet}. Their status is read live from each receipt.
