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.
