Custom Gas Token vs Native Ethereum for Your Chain

When launching a new blockchain, one of the key decisions you’ll face is whether to use Ether (ETH) as the gas token or introduce a custom gas token. This choice can significantly shape how your chain functions, the user experience, and how it interacts with the broader ecosystem. In this post, we'll break down the factors to consider when deciding between Ether and a custom token for transaction fees on your new chain.

What Are Gas Tokens?

Gas tokens are the mechanism through which users pay for computational power and storage on the network. On Ethereum-based rollups and chains, gas fees are necessary to compensate validators or nodes for processing and verifying transactions. By default, Ether (ETH) serves as the gas token for these fees, but you have the option of introducing a custom gas token specific to your chain.

Why Consider Using Ether as the Gas Token?

Simplicity and User Familiarity

Ether as a gas token offers a familiar, battle-tested experience for users. Since most users interacting with Ethereum-based ecosystems already hold ETH, they won’t need to learn new mechanics or acquire a different token. This lowers friction for both onboarding and adoption, making it easier for new users to start interacting with your chain.

For developers, using ETH simplifies integration with wallets, DeFi protocols, and existing Ethereum infrastructure. The widespread use of ETH means your chain benefits from the liquidity and accessibility of the broader Ethereum ecosystem. Additionally, ETH has a stable, known value, which can help avoid volatility issues often associated with custom tokens.

Security and Trust

Ethereum is recognized for its high security and decentralization. Choosing ETH as your gas token capitalizes on the existing trust and stability associated with Ethereum’s network, thereby boosting user confidence in the security of their transaction fees. Furthermore, your chain can benefit from Ethereum’s well-established market presence and liquidity.

Interoperability and Infrastructure

Choosing Ether allows your chain to integrate seamlessly with the existing Ethereum ecosystem. This includes wallet compatibility, DeFi protocols, and exchange listings, which are well-established for ETH. Using Ether reduces development time and resources since many of the tools and systems are already built and optimized for ETH.

Why Consider a Custom Gas Token?

Customizability and Control

A custom gas token gives you full control over the tokenomics of your chain. You can design the token’s monetary policy to suit the specific needs of your ecosystem, including inflation, deflation, or reward mechanics. This could be useful if you want to incentivize certain behaviors, such as staking or long-term holding, within your network.

A custom token can also allow for lower transaction fees tailored to your chain’s specific use case. If your application demands high transaction volumes with low fees, a custom token gives you the flexibility to implement that without being tied to ETH’s market fluctuations and fee structure.

Ecosystem Building

By introducing a custom gas token, you create an opportunity to build an ecosystem around that token. This could include partnerships, exchange listings, or unique reward structures designed specifically for your token holders. In some cases, projects prefer to have their token at the center of the user experience, particularly when creating more closed or tailored ecosystems.

Potential for Lower Transaction Costs

In certain use cases, particularly high-volume chains like gaming or social networks, the cost per transaction is a key concern. A custom gas token gives you the ability to adjust gas fees independently of Ethereum's network, which can lead to lower costs for users interacting with your chain.

Challenges of Using a Custom Gas Token

Token Economics and Liquidity

Designing a custom token requires careful thought around tokenomics. You’ll need to decide how the token will be distributed, how much of it will be in circulation, and how it will maintain long-term value. Unlike Ethereum, which has established liquidity across multiple markets, a custom token will need to build trust and liquidity from scratch, which can be a challenge for new projects.

Onboarding and User Experience

Using a custom token introduces a layer of friction for users, particularly those unfamiliar with your chain. Users will need to acquire your custom token, either through an exchange or some other distribution method, to interact with your chain. This adds complexity to the onboarding process and can be a hurdle for adoption, especially if your user base isn’t already engaged with crypto ecosystems.

Maintenance and Stability

Managing a custom gas token requires ongoing monitoring and adjustments to ensure the tokenomics stay balanced and beneficial for your chain. Market volatility can also impact the stability of your token, creating challenges for users trying to predict transaction costs.

When to Choose Ether as Your Gas Token

Choosing Ether is often the best option when:

• Your project benefits from the trust and liquidity of ETH.
• You want to minimize onboarding friction for users.
• You plan to integrate with existing Ethereum infrastructure, such as wallets and DeFi protocols.
• You’re building a financial service or application where stability, security, and market trust are essential.

When to Choose a Custom Gas Token

A custom gas token may be the right fit when:

• Your project has a unique use case that benefits from custom tokenomics.
• You want to build an ecosystem centered around your own token.
• You are working on a project where transaction costs need to be minimized for specific high-volume use cases.
• You are confident in managing token liquidity, distribution, and maintaining the token’s long-term value.

Conclusion

Deciding between Ether and a custom gas token for your chain comes down to your project’s specific goals and needs. Ether offers simplicity, security, and broad interoperability, making it an excellent choice for most applications. On the other hand, a custom gas token provides flexibility and control, ideal for projects that need custom tokenomics or aim to build a unique token-driven ecosystem. Carefully considering the trade-offs will help ensure you make the right choice for your chain’s long-term success.
