🔐Captcha Verification

Keep Your Group Bot-Free with Blockchain Verification! 🛡️

InviteStorm Bot's advanced captcha system uses blockchain wallet verification to ensure only real users with crypto wallets can join your group - no bots, no spam, just genuine members.

Why Wallet-Based Captcha?

Traditional captchas can be bypassed by sophisticated bots. Our blockchain-based verification requires users to prove wallet ownership - something bots can't fake.

Key Features:

Blockchain-Verified: Users must sign a message with their crypto wallet, proving they control a real wallet address.

Bot-Proof: Can't be bypassed by automation - requires actual wallet interaction.

Fast for Premium: Telegram Premium users can skip captcha entirely for seamless experience.

Multi-Chain Support: Verify Solana or BSC wallets based on group configuration.

One-Time Process: Once verified in one group, optionally skip in others.

Privacy-Focused: Wallet addresses used only for verification, not stored publicly.

Customizable: Admins control whether captcha is required.

How It Works

For Regular Users:

Step 1: User clicks referral link

User → Clicks join link
Bot → Detects new member
Bot → Checks if Premium user
   If Premium + fast-pass enabled → Join instantly ✅
   If not → Proceed to captcha

Step 2: Captcha challenge

Bot → User (DM):
🔐 Welcome to [Group Name]!

To join, please verify you're human by 
connecting your crypto wallet.

[🔗 Connect Wallet]
[❓ Why do I need a wallet?]

Step 3: Wallet verification

User clicks [🔗 Connect Wallet]
Bot → Sends to verification page
User → Selects chain (Solana or BSC)
User → Connects wallet (Phantom, MetaMask, etc.)
User → Signs message (no gas fee)
Verification page → Sends proof to bot
Bot → Validates signature

Step 4: Verification complete

Bot → User:
✅ Verification successful!

You've been added to [Group Name]

Welcome aboard! 🎉

Bot → Adds user to group
Bot → Credits referrer with points

For Premium Users:

User (Premium) → Clicks join link
Bot → Detects Premium status
Bot → Adds directly to group (no captcha)

Security & Privacy

What Data is Collected:

• ✅ Wallet address (for verification)

• ✅ Signature (proof of ownership)

• ✅ Telegram user ID (to link accounts)

What Data is NOT Collected:

• ❌ Private keys (never requested)

• ❌ Wallet balances (not queried)

• ❌ Transaction history (not accessed)

• ❌ Seed phrases (never asked)

How Signatures Work:

1. Bot generates random challenge text
2. User signs text with their wallet
3. Bot verifies signature matches wallet address
4. User is verified, signature discarded

No blockchain transaction
No gas fees
No on-chain record
Completely off-chain

100% Safe: Signing a message cannot move funds or grant any permissions. It only proves you control the wallet.
