Hooked leverages opBNB for cost-effective user interaction.
According to the BNB Chain blog, Hooked, BNB Chain’s gamified education platform, has effectively managed high trading volumes while maintaining efficiency and cost-effectiveness. However, transaction costs on the BNB Smart Chain can still be prohibitive due to the high volume of on-chain interactions required. This is especially true if the project requires sponsoring users’ gas bills. This problem is solved in Hooked through a two-tier architecture.
High traffic and gas-free transaction processing
Hooked is a unique platform that provides an efficient channel for non-technical users to engage with the web3 world. Users can create a Hooked wallet by logging in with their Google account. Users can then participate in daily check-ins and complete quiz challenges to earn rewards including Soulbound token NFTs and in-app credits that can be exchanged for on-chain tokens.
However, the project faced several challenges. For example, a popular campaign will lead to a significant increase in traffic that can potentially impact users’ on-chain interactions. Another challenge was the need for gasless transactions to reduce friction for users. This required the project to sponsor users’ transaction costs. Additionally, infrastructure optimization was critical to handling sudden traffic spikes while maintaining smooth user interaction despite the complexity of Web3.
Solution: opBNB and EIP4337
To solve these problems, Hooked implemented the opBNB network. opBNB is a scaling solution for the BNB chain, offering higher throughput and lower gas fees. This helped Hooked handle traffic spikes effectively, and the much lower costs meant the project had to pay users less gas compared to BSC.
The gasless solution is facilitated by a smart contract wallet powered by EIP4337, which also works as a wallet-as-a-service. This allowed users to create a Hooked wallet on opBNB by logging in using their Google account. Social Login and Smart Wallet are powered by Particle Network, which provides a built-in wallet and integrates with Google Authentication for users.
BNB Chain as an Asset Layer
As a DeFi hub, BNB Chain serves as Hooked’s asset layer. Users can seamlessly exchange in-app credits for Hooked tokens or other BEP/EIP20 tokens through the DeFi platform. You are responsible for covering any gas costs associated with such exchanges. Users can also trade Hooked tokens earned by learning on CEXs such as Binance.
Hooked’s economics allow it to sponsor gas costs for new users by using opBNB as an interaction layer. At the same time, Hooked can leverage opBNB’s higher capacity of 100 million gas per second to effectively handle traffic spikes during campaigns. Meanwhile, BSC acts as an asset layer and leverages the BNB Chain’s status as a DeFi hub. This allows users to pay gas fees directly and gives them the opportunity to explore various DeFi products within the BNB Chain ecosystem.
