Gasless DEX

The project represents an innovative approach in the Ethereum ecosystem designed to improve the user experience of traders and participants. This ecosystem is built on the Ethereum abstraction principle, which fundamentally changes the way transactions are conducted and managed on the Ethereum blockchain.

At its core, it introduces the ability for users to pay gas fees using any ERC20 token, not limited to Ethereum (ETH). This flexibility solves a significant problem for users who own different tokens and prefer not to convert them to ETH to pay for transactions. Additionally, the ecosystem includes a gas-free meta-transaction feature that further lowers the barriers to transaction by eliminating the need for users to have ETH in their wallets to pay for gas.

Another notable component of project is its portfolio manager, which uses the backend of a well-known API to provide users with an Ethereum-free experience. This tool is designed to simplify digital asset management by making it easier for traders to keep track of their portfolios without the typical friction associated with blockchain transactions.

Solution: The team developed a revolutionary DEX for Ethereum and Arbitrum that allows users to trade tokens without paying gas fees in ETH. Instead, they can pay gas fees in the tokens they trade. Key features and solutions include

Gas-free transactions: DEX is powered by OpenGSN-enabled contracts, allowing users to trade tokens without having to use ETH to pay for gas. This not only simplifies the user experience, but also opens DeFi to a wider audience by removing one of the most common barriers to entry.
Flexible payment options: Users can pay for gas with the same tokens they exchange, such as USDC, which reduces friction and makes the platform more accessible to users who do not have ETH in their wallet.

A decentralized system with an improved user experience: By integrating OpenGSN, we ensure that the DApp remains decentralized and secure, and improve the user experience by eliminating the need for multiple token balances.
Cross-network compatibility: We have designed DEX to run on both Ethereum and Arbitrum, giving users access to fast and cost-effective second-tier solutions without compromising decentralization.
Security and scalability: The DApp was built with a strong focus on security, using battle-tested smart contracts and a decentralized architecture to ensure the safety of users' funds and trades.
The result: The gas-free DEX has significantly improved the trading experience for users by eliminating the need to hold ETH to pay for gas and lowering the barrier to entry for DeFi participants. The use of OpenGSN contracts allowed for a seamless, decentralized, and secure trading environment, while support for Ethereum and Arbitrum ensured scalability and reduced transaction costs. This innovative approach attracted a wide range of users, from beginners to experienced traders, and positioned the client DEX as a leader in convenient decentralized trading solutions.
