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:

SettingRecommended ValueWhy
Per-user daily limit$0.50Enough for 20-30 transactions
Per-transaction limit$0.10Prevents expensive calls
Total budget$2 × attendeesSafe 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

Case Study: ETH Denver Workshop

Event: "Build Your First dApp" Workshop Attendees: 150 Duration: 3 hours

Setup:

  • Budget: $200
  • Per-user limit: $1
  • Contracts: 2 (NFT + Token)

Results:

  • 127 unique users (85% participation)
  • 892 transactions sponsored
  • $156 total spend (78% of budget)
  • Average $1.23 per active user

Attendee feedback: "First time I could actually use a dApp without worrying about gas!"

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

Integration with Event Platforms

GasX integrates with popular event tools:
