Step 3: Verify & Accept
  Frontend ──POST─→ /api/v3/org/invites/{token}/accept
           { address, nonce, signature }
  Backend  ├─ Verify signature
           ├─ Verify address matches recipient
           ├─ Create org member
           ├─ Assign role
           └─→ { success }

  • framer-motion animations

🎓 How It Works

Backend Integration (For Production)

// When user accepts invite:
1. Database lookup: invites.findById(token)
2. Verify SEP-10: signature validation
3. Create membership: org_members.create()
4. Assign role: Set role from invite
5. Audit log: invites_audit.log(action)
6. Notify: Send email to admin + user
7. Invalidate: Mark invite as used

🚨 Error Scenarios

Error Cause Solution
Invite not found Bad token Check URL, resend invite
Address mismatch Wrong wallet Connect correct wallet
Verification failed Bad signature Try signing again
Expired challenge Too slow Refresh, try again
Already accepted Used token Check org membership

✨ Next Steps

  1. Test the flow - Try accepting an invitation
  2. Connect backend - Database persistence
  3. Add email - Send invite link via email
  4. Monitor - Analytics + error tracking
  5. Enhance - Batch invites, custom roles
