Gasless Experiences on Ethereum Classic — Ethereum Classic Labs partners with OpenGSN

Are your DApp users frustrated about gas fees?

Well, Gas Station Network (GSN) is a pluggable service allowing DApp providers to offer gasless transactions. We’ve partnered with OpenGSN to integrate this service to the Ethereum Classic (ETC) platform!

Every operation that can be performed by a transaction or smart contract on the ETC platform requires a cost in gas. Gas is the mechanism that measures how much “work” is required to perform an operation [1]. This cost in gas is paid in ETC, in addition to the ETC that is needed to fulfill the transaction. For example, let’s say you had 1.00 ETC and wanted to make a transaction on a DEX or send 1.00 ETC to a recipient. This transaction will require 1.00 ETC, in addition to a decimal amount of ETC. So, the transaction will actually cost 1.00001 ETC or whatever the gas estimate of the platform is at the time.

“One of our main goals is to make Ethereum Classic not just accessible for anyone building on blockchain, but to ensure these options are affordable and best suit the developer ecosystem,” said James Wo, Founder of ETC Labs.

Gas is an essential part of the ETC platform because a transaction fee prevents the network from being spammed by worthless transactions or bad smart contracts. While Gas is an essential mechanism, it does have some User Experience drawbacks. Being, a user has an unknown additional amount of ETC to cover gas costs which can change rapidly based on current platform demand, and many users do not want to frequently visit an exchange. Enter meta-transactions. This is a fancy name for a simple idea: a third-party (called a relayer) can send another user’s transactions and pay themselves for the gas cost [2].

GSN improves this user experience problem by providing a decentralized network of relayers that allows DApp providers to pay for their users’ gas costs. This UX improvement helps ease user onboarding and the overall marketability of a DApp.

How does it work?

Simply, a smart contract is built tied to GSN and maintains an amount in ETC to subsidize users’ gas costs. When a user makes a transaction with the smart contract, it’s relayed to GSN which charges the smart contract to pay the users’ transaction, plus a small service fee. Once integrated with GSN, the entire process is automated on the platform and user get a lovely gasless experience with minimal costs to the DApp provider.

As part of the Gitcoin virtual hackathon for New York Blockchain Week, we’re unveiling a round of bounties, including “Best GSN Project on Ethereum Classic $500–1000,” which challenges miners to create a project that utilizes GSN on Ethereum Classic. This is an open-ended bounty that can be fun and creative but most importantly, promotes GSN use on Ethereum Classic. Click here to learn more and start solving the bounty.
