Safe has informed its users that Safe{Wallet} now automatically flags suspected address-poisoning attempts, adding a built-in warning layer against one of crypto's most deceptive scams. However, the protection appears to build on tooling that security partner Blockaid documented as already live in the wallet back in 2024, rather than representing an entirely new feature.

The wallet operator announced the capability in a September 2, 2026 post on X, framing address poisoning as a major security threat and pointing users toward more detail on how the flagging works. The company said the alerts run automatically so users "stay in control" during transfers.

Safe Wallet is widely used for multisig custody by treasuries, DAOs, and protocol teams, which raises the stakes for interface-level attacks: large balances and multi-signature workflows mean a single deceived signer or copied address can affect substantial funds. The February 2025 Bybit hack, in which roughly $1.5 billion was stolen after attackers compromised Safe's interface infrastructure, underscored how attractive Safe-connected surfaces are to attackers, even though that incident involved a supply-chain compromise rather than address poisoning.

What Safe Wallet's automatic alerts are designed to do

In plain terms, the feature watches transactions for imitation activity and surfaces a warning before a user acts on a deceptive address. Safe's knowledge base says imitation transactions are marked as malicious and that users receive a warning when they copy a poisoned address, per the company's explainer.

The update is pitched as a wallet-security enhancement rather than a protocol change, aimed at everyday users who move funds between addresses and rely on transaction history to copy destinations. That makes it directly relevant to routine self-custody habits, where a single wrong paste can send money to an attacker.

Here is how Safe put the message to its users:

Address poisoning is one of the sneakiest attacks in crypto.⁰Safe{Wallet} now flags it automatically so you stay in control.

One caveat worth noting: it is not established that the September 2 post reflects a brand-new feature. Blockaid's integration announcement described Safe Wallet alerting users about potentially malicious destination addresses well before this date, so the post may be reinforcing an existing protection rather than debuting one.

Why address poisoning remains a persistent threat

Address poisoning is a deception tactic in which attackers seed a victim's transaction history with lookalike addresses, often matching the first and last characters of a real one, hoping the user copies the fake on their next transfer. The scam relies on user confusion and copy-paste shortcuts rather than any code exploit.

The scale is not trivial. Blockaid's March 9, 2026 threat report said it had flagged 65.4 million address-poisoning transactions since January 2025, and identified roughly 15,000 malicious lookalike proxy addresses targeting Safe Wallet users specifically, in its research on the tactic.

Safe also documents a more advanced variant it calls nested Safe poisoning, in which a malicious Safe can appear inside a parent Safe's interface even though the parent's signers never created or authorized it. Safe said one observed campaign spun up about 200 malicious Safes in a single transaction, according to its knowledge base.

What the update could mean for users, and where it falls short

The optimistic view is straightforward: proactive warnings can catch a bad transfer before it is signed, reducing accidental sends driven by copy-paste mistakes. Blockaid's integration post said Safe Wallet alerts users if they are about to send funds to a potentially malicious address and that the checks operate automatically with every transaction, as described in its September 2024 rollout.

On the other hand, automated alerts complement, rather than replace, manual address verification, and no fetched dated changelog confirms a fresh September 2026 launch. Security tooling can also produce false positives or lull users into skipping their own checks, which matters because attackers are actively adapting to the very defenses being marketed.

Anti-scam tooling has become a competitive signal in wallet design, much as security and governance moves shape trust elsewhere in the market, from Coinbase's recent board and audit changes to how firms position consumer protection. For users, the practical takeaway is that a warning is a prompt to slow down, not a guarantee. A related habit worth watching is the wider adoption of verification practices such as address allowlists and test transfers, which several wallet makers and security firms now recommend alongside automated detection.

Market reaction was muted. SAFE traded at $0.0946, down 4.16% over 24 hours, with a market cap near $73 million, leaving the token's move more tied to broad conditions than to the security news itself.

Broader sentiment leaned optimistic, with the Fear & Greed Index at 65, in "Greed" territory, even as tokens like XRP have wobbled on macro risk. For Safe holders, the security push and the price drift are, for now, separate stories.
