How to Sponsor Gas for Your Crypto Meetup or Hackathon
Running a Web3 event? The last thing you want is attendees struggling with gas fees during your workshop or hackathon. This guide shows you how to set up seamless gas sponsorship for your event.
Why Sponsor Gas at Events?
The Problem
- 60% of hackathon participants are Web3 newcomers
- New users don't have ETH for gas fees
- Faucets are unreliable and slow
- Manual ETH distribution is a nightmare
The Solution
With GasX, you can:
- Pre-fund a gas budget for your event
- Set time limits matching your event schedule
- Track usage per attendee
- Top up remotely if needed
Event Gas Sponsorship Checklist
Before your event, make sure you have:
- GasX account created
- Campaign configured with event dates
- Budget allocated (we recommend $0.50-$2 per attendee)
- Contracts allowlisted (workshop contracts, NFT mints, etc.)
- QR code or link ready for attendees
Step-by-Step Setup
1. Create Your Event Campaign
Go to the GasX Dashboard and create a new campaign:
Campaign Settings:
- Name: "ETH Denver 2024 Workshop" (descriptive name)
- Start Date: Event start time
- End Date: Event end time + 1 hour buffer
- Budget: Total gas budget in USD
2. Configure Spending Limits
Set appropriate limits to prevent abuse:
| Setting | Recommended Value | Why |
|---|---|---|
| Per-user daily limit | $0.50 | Enough for 20-30 transactions |
| Per-transaction limit | $0.10 | Prevents expensive calls |
| Total budget | $2 × attendees | Safe buffer |
3. Allowlist Your Contracts
Only sponsor transactions to contracts your attendees will use:
Workshop NFT: 0x1234...
Demo DEX: 0x5678...
Voting Contract: 0x9abc...
Pro tip: Create a test contract on testnet first to verify everything works.
4. Generate Attendee Access
You have two options:
Option A: Public QR Code
- Generate a campaign link
- Create a QR code
- Display at your event
Option B: Unique Codes
- Generate codes for each attendee
- Distribute during registration
- Better tracking, but more overhead
5. Set Up Monitoring
During the event, monitor your campaign:
- Open the Analytics Dashboard
- Watch for unusual spending patterns
- Be ready to top up if needed

Common Mistakes to Avoid
1. Setting Budget Too Low
- Attendees hit limits mid-workshop
- Creates frustration and support requests
- Solution: Budget 20% more than you think you need
2. Forgetting Time Zones
- Campaign ends before event does
- Solution: Use UTC and add buffer time
3. Not Testing Beforehand
- Discover issues during the event
- Solution: Run through the full flow on testnet
4. No Monitoring During Event
- Budget depletes without notice
- Solution: Assign someone to watch the dashboard
