Cardano Priority Wallet is a Chrome extension designed for users of the Cardano blockchain network. It enables users to prioritize transactions with high fees, ensuring efficient processing. By optimizing transaction parameters internally, such as fees, the extension aims to accelerate confirmation times on the Cardano blockchain. It analyzes transaction data, adjusts fee structures, and execution units to increase the likelihood of transactions being promptly mined and added to blocks.

The extension serves as an intermediary between transactions processed through a Cardano decentralized application (DApp) and the user's Cardano wallet. It optimizes execution units and applies slight fee increments to enhance the likelihood of miners prioritizing mining. The extension supports six popular Cardano wallet extensions and improves usability by displaying installed wallets in the browser, allowing for swift wallet selection.
