Why is 0x6840…b77a flagged?
This address is flagged in public scam/exploit label data as Exploit — linked to a smart-contract exploit — an address used to drain funds from a vulnerable DeFi protocol. Its Hopchain label comes from the source list's own name for it: “Dexible Exploiter” on arbitrum-mainnet. If it shows up as a connection on a wallet you're checking, don't interact with it, sign anything it prompts, or visit any site linked to it.
- Interact with this address, or sign any transaction it prompts
- Visit a site linked in a token or message associated with it
- Try to "recover" or move on tokens it sent you by following its instructions
- Assume a familiar-looking name or logo means it's legitimate
- Ignore unsolicited tokens or dust sent from it — it's safe to just leave them
- Check your wallet's token approvals and revoke anything you don't recognize
- Double-check a project's real official URL before connecting a wallet
- See the full connection graph if you want to trace it further

Is it dangerous just to receive tokens from a flagged address?
Receiving alone doesn't put your wallet at risk. The danger comes from interacting back —
don't visit any site linked in the token's name or metadata, and don't sign anything it
prompts, including a "claim" or "approve" transaction.
Why does Hopchain flag this specific address?
It's cross-referenced against verified public phishing/exploit/heist/scam label data
(see how it works). Coverage isn't complete for every chain —
Ethereum mainnet and Base aren't covered by this particular source yet, a known, disclosed gap.
What if I already approved this address to spend a token?
Open your wallet's connected-apps or approvals view (or a revocation tool) and revoke it.
An approval only lets a contract move funds you granted it access to — revoking it removes
that permission.
