2. Context of the Proposal

2.1 About PolkaGate

PolkaGate is a project that enhances the user experience for interacting with Substrate-based chains like Polkadot and Kusama. It simplifies complex processes such as staking, governance participation, and asset management. With seamless integration into popular platforms like MetaMask and its own dedicated extension, PolkaGate empowers users to manage their digital assets and engage in the network’s governance through intuitive interfaces. Since its inception, PolkaGate has focused on reducing entry barriers for both newcomers and experienced users.

2.2 Overview of Products

PolkaGate comprises two core products:

• PolkaGate Extension: A browser extension designed to interact with Substrate-based networks. It enables users to manage multiple accounts, sign transactions, and participate in on-chain governance directly from their browser.
