In the fast-moving world of Ethereum, high gas fees can make or break a transaction—especially during peak network congestion. Whether you're arbitraging decentralized exchanges, participating in a high-demand token launch, or simply executing complex smart contract interactions, unpredictable gas prices pose a real financial challenge. Enter GasToken, an innovative solution that allows users to effectively "bank" gas when prices are low and use it when prices spike.
GasToken isn't just another ERC20 token—it's a clever use of Ethereum's built-in refund mechanics to tokenize gas costs. By leveraging storage and contract deletion refunds, GasToken enables users to reduce their effective gas expenses during high-fee periods. This article dives deep into how GasToken works, its two variants (GST1 and GST2), real-world savings potential, and why it matters for Ethereum users seeking cost efficiency.
What Is Gas on Ethereum?
Gas is the fundamental unit of computational effort on the Ethereum network. Every operation—from simple ETH transfers to complex smart contract executions—consumes gas. Users pay for this gas in ETH, with the price per unit (measured in gwei) fluctuating based on network demand.
When the network is busy, users often bid higher gas prices to get their transactions prioritized by miners. This can push gas prices from under 1 gwei during off-peak hours to over 100 gwei during high-traffic events like ICOs or NFT mints.

Why Use GasToken?
The volatility of Ethereum gas prices creates a unique opportunity: arbitrage through time. GasToken capitalizes on this by allowing users to "store" gas value when prices are low and "spend" it when prices are high.
Here’s the core idea:
- Mint GasTokens when gas is cheap (e.g., late at night or during low network usage).
- Burn (free) GasTokens during high-gas periods to receive refunds that offset transaction costs.
This mechanism gives users a strategic advantage in competitive environments—like front-running arbitrage opportunities or securing early access to limited token sales—without paying proportionally higher fees.
Moreover, as Ethereum blocks become increasingly full, block space becomes more valuable. GasToken provides a way to hedge against this growing scarcity.
How Does GasToken Work?
GasToken exploits Ethereum’s gas refund system, designed to incentivize efficient use of blockchain storage. When a contract clears storage or deletes another contract, it receives a partial gas refund—up to 50% of the transaction’s total gas cost.
There are two main variants of GasToken:
GST1: Storage-Based Gas Token
- Uses the
SSTOREmechanism to write data into contract storage when gas is cheap. - Later deletes that data to trigger a 15,000 gas refund per storage slot.
- Ideal for moderate gas price fluctuations (2x–3.7x increase).
GST2: Contract-Based Gas Token
- Creates minimal child contracts when gas is low.
- Destroys them later via
SELFDESTRUCTto claim a 24,000 gas refund per contract. - More efficient at higher volatility (above 3.7x), with theoretical savings up to 3.49x.
Both follow the ERC20 standard, enabling transfer and exchange between users. The key difference lies in efficiency under varying market conditions.
Maximizing Savings: When to Use GST1 vs. GST2
Choosing the right variant depends on expected gas price volatility:
| Scenario | Recommended Token |
|---|---|
| Gas price doubles (2x–3.7x increase) | GST1 |
| Gas price increases more than 3.7x | GST2 |
For example:
- If you mint tokens at 1 gwei and redeem them at 50 gwei, GST2 delivers significantly higher savings.
- Batch processing (minting or freeing many tokens at once) improves efficiency by amortizing fixed costs.
💡 Pro Tip: Always ensure your free transaction includes sufficient gas—especially for GST2—to avoid issues caused by a known Solidity compiler quirk.👉 Learn how advanced traders manage gas costs during volatile markets.
Real-World Efficiency and Calculations
Let’s break down potential savings:
Suppose:
- You mint 1 GST2 token when gas is 1 gwei
- You free it when gas is 50 gwei
- Your target transaction uses 2,000,000 gas
The cost to mint ≈ 36,543 gas × 1 gwei = 0.000036543 ETH
The cost to free ≈ 6,870 gas × 50 gwei = 0.0003435 ETH
Refund received = 24,000 gas × 50 gwei = 0.0012 ETH
Net savings ≈ 0.00082 ETH per token, with diminishing overhead at scale.
Even after accounting for minting and freeing costs, users can achieve up to 3.49x effective savings under extreme volatility.
Security and Risks: What You Should Know
GasToken was developed by blockchain researchers from institutions including ETH Zürich, Cornell Tech, and Stanford. While the code is open-source, well-tested, and live on mainnet, no independent security audit has been conducted.
Important caveats:
- The contract contains no warranty or liability.
- Future Ethereum upgrades (e.g., state rent, EIP changes) may render GasToken obsolete.
- Widespread adoption could theoretically increase network strain due to bloated storage.
Use at your own risk—and always review the code before integrating.
Frequently Asked Questions (FAQ)
Q: Is there an ICO or token sale for GasToken?
A: No. GasToken is not an investment vehicle. There is no sale, launch, or distribution event. You can mint and use it directly on-chain.
Q: Who created GasToken?
A: A team of academic researchers from IC3, Cornell Tech, ETH Zürich, and Stanford University. It originated from Project Chicago, focused on blockchain resource economics.
Q: Can GasToken be used on Ethereum Classic?
A: Yes. Both GST1 and GST2 are deployed on Ethereum Classic with minor improvements in the GST2 version.
Q: Does EIP87 or sharding make GasToken obsolete?
A: Possibly. Any change to Ethereum’s refund rules or state pricing model could impact GasToken’s viability. The developers acknowledge this and may even advocate for such changes.
Q: Isn’t this bad for the network?
A: It has trade-offs. While it helps users hedge against fee spikes, it may contribute to long-term storage bloat. However, it also promotes better price discovery for blockchain resources.
Q: Is GasToken secure?
A: The contracts are simple and tested, but not audited. Use them only after thorough review.
Final Thoughts: A Tool for Strategic Ethereum Users
GasToken represents a fascinating intersection of economics, game theory, and smart contract engineering. It’s not a magic bullet—but for savvy users, it’s a powerful tool to reduce transaction costs during high-pressure moments on Ethereum.
As blockchain ecosystems evolve, innovations like GasToken highlight the importance of dynamic resource pricing and user-level financial instruments. Whether you're a trader, developer, or DeFi participant, understanding how to leverage gas efficiently can provide a tangible edge.
