A next-generation expense management platform that eliminates crypto payment friction through intelligent cross-chain infrastructure. Our solution enables seamless group expense settlements where users can pay in their native tokens while recipients receive in their preferred cryptocurrency - all powered by 1inch Fusion APIs and automated cross-chain swaps.

The platform introduces a dual-value proposition: consumer convenience through frictionless crypto payments, and data monetization via Filecoin Lighthouse integration. Users store receipts securely on decentralized storage and earn reward tokens by opting into anonymous data sharing, creating valuable business intelligence datasets.

This approach tackles two major adoption barriers: the complexity of cross-chain transactions and the lack of incentive structures in consumer crypto apps. By combining state channels for efficient settlements, automated currency conversion, and tokenized data rewards, we're building the infrastructure for mainstream DeFi adoption through familiar expense-sharing workflows.

The result is a consumer-first platform that drives crypto utility while establishing sustainable revenue streams through privacy-preserving data monetization.
