ERC-7715: Grant Permissions from Wallets

ERC-7715 introduces a structured permission framework that allows smart accounts to grant limited, scoped access to external dApps or services. Traditionally, blockchain interactions require a signature for every single transaction, which creates significant UX friction. This standard proposes a way for a wallet to grant 'permissions' to a dApp—such as spending a certain amount of ERC-20 tokens or interacting with specific contract methods—without requiring constant user intervention for each action. This is achieved by creating an ephemeral session key or a constrained grant that is linked to the primary account. The methodology relies on defining clear constraints and scopes, ensuring that the granting process is secure and transparent to the end user. By facilitating these 'permissions,' the standard enables a 'web-like' experience in decentralized finance and gaming, where users can authorize a service to act on their behalf within defined safety parameters. This reduces reliance on full account access and improves the user experience by enabling batchable, automated, and streamlined transactions, while maintaining the non-custodial and secure nature of blockchain-based assets.
