A Telegram anti-spam bot for crypto groups needs to do more than filter swear words and flood messages. It has to stop known scammers at the door, delete phishing links and wallet drainers before anyone clicks, and catch fake admins. Heimdall is a free anti-scam bot that does exactly this, and it is already protecting over 3 million users across 40,000+ groups.
This guide walks through what Heimdall does, how each feature works, and where its limits are.
What Makes a Good Anti-Scam Bot for Telegram
Generic spam filters are built for ads and floods. Crypto groups face a different threat: scams designed to take money. Before you add any bot, check it covers these points:
- Known-scammer blocking. It should recognise accounts that have already scammed other groups, not just react after they post.
- Link and message scanning. Phishing sites and drainer links must be removed in seconds, not after an admin wakes up.
- Impersonation detection. Fake admins are the most effective scam in crypto groups.
- Contract address awareness. A wrong contract address during a launch is a real loss for buyers.
- Automatic action. The bot should ban or mute on its own, not just leave a warning.
- No setup burden. The more a bot needs tuning, the more likely it is misconfigured.
- Cost. Protection should not depend on a group's budget.
Heimdall Features: What the Anti-Scam Bot Does
Heimdall is built by ODIN Tools for crypto and Web3 communities. Here is each feature in detail.
Global Scammer List
Every new member is checked against a shared list of known scammers, drainers and phishing operators. The list is shared across every group that uses Heimdall, so a scammer banned in one group is blocked in all of them.
This is the feature that changes the economics for scammers. On their own, each group fights the same accounts again and again. With a shared list, being caught once has consequences across thousands of groups.
Entries on the list come from detected scam behaviour, reports from group admins and patterns seen across groups.
Message Scanning
Heimdall scans messages in your group as they are sent. Phishing links, wallet drainers, fake contract addresses, impersonation and scam promotions are deleted in milliseconds, before your members see them.
Detection uses pattern matching, keyword detection and link analysis. Heimdall does not store every message. Only messages flagged as potential violations may be logged for review.
Impersonator and Fake Admin Detection
Scammers copy an admin's name and profile picture to look official, then DM members who ask for help. Heimdall catches fake admins and copied names, so the impersonator is removed from the group before they can build a list of targets.
Suspicious Token Alerts
Heimdall flags suspicious or unverified Solana contract addresses shared in your group. This helps protect members from rugs and honeypots, and from copycat tokens posted during a launch.
Automatic Moderation
When Heimdall finds an offender, it acts on its own. It bans, mutes or reports them, and it can alert admins. No manual review is needed for the routine cases, which frees your admins for the conversations that need a human.
Zero Setup
Add Heimdall as an admin and it starts working. There are no commands to learn and no configuration screens. The full setup takes about a minute.
Free, Forever
There is no subscription, no premium tier and no hidden costs for Heimdall's protection.
| Feature | What it stops |
|---|---|
| Global scammer list | Known scammers, drainers and phishing operators joining your group |
| Message scanning | Phishing links, drainers, fake contract addresses, scam promotions |
| Fake admin detection | Impersonators using copied names |
| Suspicious token alerts | Unverified or suspicious Solana contract addresses |
| Automatic moderation | Offenders staying in the group until an admin notices |
Heimdall Telegram Bot vs Doing It by Hand
| Factor | Manual moderation | Heimdall |
|---|---|---|
| Response time | When an admin sees it | Milliseconds |
| Repeat scammers | Banned one group at a time | Blocked in every Heimdall group |
| Coverage | Depends on admin time zones | Around the clock |
| Cost | Admin time | Free |
| Judgement on edge cases | Strong | Not a replacement for humans |
The best setup uses both. Heimdall handles the volume and speed, your admins handle judgement and community questions. For the manual side, including permissions, slow mode and a pinned safety message, read How to stop scammers in a Telegram group.
What Heimdall Does Not Do
Being clear about limits helps you plan your moderation:
- It does not read private messages. Heimdall only operates in groups where an admin added it. Fake support DMs between users are outside its reach, though removing the scammer from your group cuts off their access to your member list.
- It is not perfect. Like any automated system, it can miss a violation or flag a legitimate message. Keep human admins in the loop.
- It does not replace your rules. You still decide your group's standards and how members can contact admins about moderation decisions.
Note: If someone is banned or listed by mistake, they can request a human review by emailing [email protected] or contacting the Heimdall bot. Requests are answered within 30 days, and records found to be inaccurate are corrected or removed.
Who Heimdall Is For
Heimdall is built for crypto and Web3 communities, and it works in any Telegram group or supergroup. It suits:
- Token communities that see waves of fake contract addresses and drainer links around launches.
- Trading and alpha groups where members share links and contract addresses all day.
- Project support groups where members ask for help in public and attract fake support DMs.
- NFT and DAO communities that get airdrop and giveaway scams.
Because Heimdall works alongside your other bots, you do not need to remove your existing welcome bot, captcha or utility bots.
How to Add the Heimdall Anti-Spam Bot
Setup takes three steps: start @heimdall_odintools_bot, add it to your group, and make it an admin with permission to delete messages and ban users. Protection starts at once.
For the full step-by-step with permissions explained, what to tell your members and how to check it is working, follow the Heimdall Telegram bot setup guide.
Tip: Heimdall's terms ask group admins to let members know Heimdall is active in the group. A one-line note in your pinned rules is enough.
