This proposal outlines the native integration of Polkadot functionality into Brave’s self-custody wallet, granting Brave’s 80M+ monthly active users direct access to the Polkadot and Kusama ecosystems. This integration will be implemented natively in Brave’s core C++ architecture over 12 months, ensuring maximum security, privacy, and performance, while also committing to a 24-month maintenance period for ongoing updates and optimizations.
Brave's extensive user base provides a significant opportunity for Polkadot adoption:
By integrating Polkadot natively, Brave Wallet will streamline user access to Web3, facilitating secure XCM-based cross-chain transfers, governance participation, and direct dApp interactions.

These images provide insight into how Polkadot will be incorporated into Brave Wallet’s multi-chain experience.
These updates ensure that Brave Wallet becomes a true multi-chain platform, where Polkadot users can interact with the ecosystem.



This integration represents a significant milestone for Polkadot adoption, onboarding millions of new users through Brave's privacy-first, security-focused browser environment. By implementing a fully native, high-performance C++ integration, Brave Wallet will serve as a gateway to Web3, enabling cross-parachain transactions, and dApp interactions—all without requiring third-party extensions. Brave Wallet supports multiple blockchains, including ETH, BTC, SOL, ZEC, and FIL, enabling seamless native cross-integration with the Polkadot ecosystem.
This proposal ensures long-term ecosystem growth, open-source contributions, and measurable adoption metrics, making it a strategic win for both Brave and Polkadot.
Brave is a privacy-focused browser and search engine committed to empowering users with control over their online data and experiences. Our integrated Brave Wallet provides a seamless way to access Web3 with support for Ethereum, EVM chains, Solana, Bitcoin, and NFTs - no extensions required. Brave Rewards, our privacy-preserving ad platform, has the most crypto-centric audience available today.
Founded by JavaScript creator Brendan Eich, Brave is an open-source project fostering innovation through transparency and collaboration. The key team members involved in this proposal are:
Major brands across industries have trusted our advertising platforms, including Verizon, Ford, Lufthansa, Crocs, Venom, Mayfair, eToro, Crypto.com, Solana, Upland, Near, and Nexo.
With privacy at its core, Brave aims to improve the way we interact with both Web 2.0 and Web3.
Brave, a privacy-focused browser, plans to integrate Polkadot functionality into its self-custody wallet, giving its over 80 million monthly active users access to the Polkadot and Kusama ecosystems. This integration will be done natively in Brave's core C++ architecture over 12 months, with a 24-month maintenance period for updates and optimizations. The total investment for this project is $3,000,000 USDC. The development will be divided into five milestones, covering research, relay chains support, network and parachains support, assets support, and ecosystem integration and deployment. Brave will open-source all Polkadot-related code and commit to a 24-month maintenance period. Additionally, Brave will provide a $100K ad credit to Polkadot upon proposal approval. This integration aims to make Brave Wallet a true multi-chain platform and a gateway to Web3, enabling cross-parachain transactions and dApp interactions without third-party extensions.
