To streamline the user experience in a blockchain-based gaming dApp, consider the following strategies:
1. Batch Transactions:
Batching allows you to group multiple actions into a single transaction. This can significantly reduce the frequency of Metamask prompts as players can make multiple decisions and then confirm them all at once.
Benefits:
- User Experience: Players engage in uninterrupted gameplay, performing several in-game actions before needing to confirm a single transaction.
- Gas Efficiency: Batching can sometimes save on gas fees, as fewer individual transaction overheads are needed.
2. Meta-Transactions:
Meta-transactions capture the essence of user intent without immediately transacting on the blockchain. Instead of a user paying gas for each interaction, meta-transactions enable another party (like a relayer) to sponsor and broadcast these transactions.
Mechanisms:
Gas Station Network (GSN): This decentralized solution allows dApps to subsidize transaction costs, offering a seamless experience to users. Users sign a message (their "intent"), and a relayer in the GSN processes the transaction on their behalf.
ERC-4337 Account Abstraction with Smart Contract Accounts: This recent standard offers a way to represent user operations without immediate blockchain transactions. If your users smart accounts supports session keys then you can use this to "automatically sign" transactions for a specific period. You can also take a look at this article by MetaMask for a comprehensive idea of all the features that are enabled by smart contract accounts.
Benefits:
Speed & UX: Users only sign a message indicating their intent, which is typically faster than signing an entire transaction. This is because, for transactions, wallets often need to make preliminary calls to estimate gas cost and get the gas price.
Gas Abstraction: Users don't need to own or understand ETH for gas payments, making the dApp more accessible, especially to newcomers.
