If you trade with Telegram bots, DeFi apps, or new tokens, you are constantly giving token approvals to smart contracts. Some of these approvals stay active forever.
And that means a bad contract can drain your wallet at any time.
Good news: you can revoke these permissions easily, and for free, on every chain.
Here is the cleanest, most complete list of free token-approval revoker tools available today.

Super simple: if you don’t know where to start, go with Revoke.cash (EVM) and Solana Revoker (SOL).
1. Revoke.cash
Best for Ethereum, Polygon, BNB, Arbitrum, Optimism + more
Revoke.cash is the most trusted and easiest tool.
You connect your wallet → it shows all approvals → you click Revoke.
Why people love it:
- Supports almost every EVM chain
- Clean UI
- Works on mobile
- Browser extension warns you about risky approvals
If you use Telegram trading bots on EVM chains, this should be your weekly checkup tool.
2. Unrekt (Allowance Checker)
Great for hunting down forgotten approvals
Unrekt is simple and fast.
It scans your wallet on many EVM networks and shows:
- Spender address
- Token
- Allowance value
Perfect when you want a clean, minimal list without extra features.
3. DeBank Permissions
Good all-in-one dashboard for multi-chain users
DeBank is a portfolio tracker, but it also has a Permissions tab.
It shows exactly which contracts can spend your tokens.
Useful if you want:
- One place to view all assets
- One place to view all approvals
- A mobile app
Great for reviewing everything after using new Telegram bots or DEXs.
4. MetaMask Portfolio
The easiest option if you already use MetaMask
MetaMask has a built-in permissions panel where you can:
- View spending allowances
- Reduce or remove them
- Revoke unlimited approvals
If you’re on Ethereum, Polygon or BNB and already use MetaMask, this is quick and smooth.
5. Phantom Wallet (Solana)
For Solana users — the “connected apps” view
Phantom doesn’t show every single type of permission, but it does show:
- Connected apps
- Trusted websites
- Active sessions
If you interacted with a risky Solana dApp, open Phantom → disconnect → then use one of the next tools.
6. Solana Revoker
The only full “true” Solana token-delegate revoker
Solana apps often ask for delegate permissions.
These can stay active even when you disconnect.
Solana Revoker scans all:
- Token approvals
- NFT approvals
- Unknown delegates
- Suspicious perms
Then you can revoke with one click.
If you trade SPL tokens or use Solana Telegram bots, this tool is essential.
7. CoinTool (ct.app)
Multi-tool platform with approval checker
CoinTool is basically a Swiss-army knife for crypto.
One of its tools is an approval checker for:
- Ethereum
- BNB Chain
- Tron
Good as an extra safety check or quick scan.
8. Revoker.info (Tron)
Best free TRON approval revoker
If you use Tron (TRC-20 tokens), go here.
Paste your address → see every approval → revoke the ones you don’t trust.
Super clean and super easy.
🔹 Bonus Solana Tool: ClaimYourSol (Recover FREE SOL You Didn’t Know You Had)
If you’ve used Solana even a little: traded meme coins, minted NFTs, claimed airdrops, you almost definitely have SOL stuck in old SPL token accounts. It’s not gone. It’s not stolen. It’s just locked as “rent.”
ClaimYourSol is the fastest free tool to get it back.
Here’s what it does in seconds:
- Scans your wallet for empty SPL accounts
- Shows how much SOL each one is holding
- Closes them safely
- Sends all the recovered SOL back to you
It’s simple, non-custodial, and feels like finding money in an old pair of jeans.
If you use Solana bots or do a lot of on-chain activity, this is a must-use tool.

🔒 Pro Tips for Staying Safe With Telegram Bots
These are small habits but they save people a lot of money.
- Use a burner wallet for bots
- Never use unlimited approvals when possible
- Always revoke after trading risky tokens
- Check approvals weekly
- Disconnect WalletConnect sessions on your phone
- Don’t keep large balances in hot wallets
- Avoid bots that ask too many permissions
- If something “feels wrong” — stop immediately
Being paranoid is good in crypto. Most hacks happen because people forget old approvals.
FAQ
How do I revoke token approvals on Ethereum or BNB?
You can use a free tool like Revoke.cash or Unrekt. Connect your wallet, select the network, and click “Revoke” next to the contract you no longer trust. It sends a small on-chain transaction that removes permission from that spender. This works on all major EVM chains.
Why do I need to revoke old approvals?
Old approvals stay active forever. If one of those contracts becomes unsafe or gets exploited, it can drain the tokens you approved months ago. Revoking resets the allowance to zero and closes that door. It’s one of the simplest ways to protect your wallet.
Does revoking approvals cost gas?
Yes, because revoking is an on-chain transaction. But the cost is usually small, especially on BNB, Polygon, or Arbitrum. The tools themselves are free — you only pay normal network fees.
How do I revoke approvals on Solana?
Solana uses “delegates” instead of ERC-20 allowances. Tools like Solana Revoker scan your wallet and show all active delegates. You connect Phantom, click “Revoke,” and the tool removes those permissions. This is important after using new or untrusted Solana apps.
Can a Telegram bot drain my wallet if I don’t revoke approvals?
If you approve a malicious contract, the bot can drain tokens even when you’re offline. This is why bots should always be used with a burner wallet, limited allowances, and weekly approval checks. Revoking removes that risk completely.
