May 2025: Delivered a focused feature upgrade for ResearchHub/web by enabling a buy/sell flow for ResearchCoin (RSC) within the UserBalanceSection. Key changes include renaming the existing SwapModal to BuyModal, introducing a new SellModal, and updating the UI to present Buy/Sell actions along with wallet-connect text that reflects the new trading functionality. This reduces friction for RSC transactions and strengthens the in-app trading UX, laying groundwork for streamlined RSC liquidity and onboarding. Commit 7bf5c7438f6d04b31a35bff283e4381422f05300 documents the change and provides traceability.
