Currently, Payflow is focused on Farcaster integration.\n\nPayflow is not just a wallet; it\u2019s an ecosystem of embeddable payment tools that can easily be plugged into:\n- Feeds\n- Chats\n- Standalone apps\n\n## Solving Payment Fragmentation\n\nIn the rapidly evolving landscape of decentralized applications (dApps), users face significant challenges in managing payments across various social primitives. Existing solutions lack seamless integration between these platforms, leading to:\n- Fragmented user experiences\n- Complex payment workflows\n- Limited interoperability between chains and tokens.\n\nAs a result, users struggle with discovering and managing their assets.\n\n## Developer Solutions\n\nFor developers of other dApps, the burden of developing their own payment solutions results in:\n- Duplicated efforts\n- Increased development time\n- Resource constraints\n\nPayflow addresses these challenges by providing an onchain social payments ecosystem that can be easily integrated based on underlying common social primitives.\n\n## Key Features\n\n- Payflow is a PWA integrated into Farcaster through:\n  - Frames\n  - Cast actions\n  - Bot commands\n  - Mini-apps\n  - Native integration with Warpcast Pay.\n- P2P payments directly within a social feed or app.\n- Buy or gift Farcaster storage.\n- Mint or gift collectibles from platforms like Zora, Rodeo Club, and Highlights.\n- Buy or gift Moxie-based fan tokens.\n- Each payment feature has a dedicated cast action and frame to embed the payment experience into Farcaster.\n- Cross-chain payments supported with 25+ tokens.\n- Aggregates your contact book from various social graphs and provides access to your payment history within Payflow.\n- Payflow offers a single platform to manage all social payments, supporting community tokens and solving real problems not yet addressed by the Farcaster ecosystem.\n\n## Supported Chains\n\n- Base\n- Optimism\n- Arbitrum\n- Zora\n- Mode\n- Degen L3\n\n> Payflow is willing to extend its presence to Polygon, helping Farcaster communities leverage social payments powered by Payflow to utilize their tokens on Polygon.\n\n## Useful Links\n\n- [Official Website](https://payflow.me)\n- [Farcaster](https://warpcast.com/sinaver.eth)\n- [Farcaster Channel](https://warpcast.com/~/channel/payflow)\n- [GitHub Repository](https://github.com/sidrisov/payflow)", "lastUpdated": 0, "projectGithub": "Payflow-Labs", "projectTwitter": "payflowme"}, "recipient": "0x0dEe77c83cB8b14fA95497825dF93202AbF6ad83"}}
