From 043515d80a09051b73e6ca47960eaa2eedc1facf Mon Sep 17 00:00:00 2001 From: openhands Date: Sat, 20 Jun 2026 20:04:30 +0100 Subject: [PATCH 1/3] fix: resolve TypeScript errors for main branch - Add useOptimisticTransactions import to group-details.tsx - Fix STELLAR_RPC_URL export in web3-provider.tsx and update yield-dashboard.tsx - Add missing rpc import to yield-dashboard.tsx Resolves TypeScript errors: - frontend/components/group/group-details.tsx(39,31): error TS2304: Cannot find name 'useOptimisticTransactions'. - frontend/components/group/yield-dashboard.tsx(15,18): error TS2459: Module 'useJointSaveContracts' declares 'STELLAR_RPC_URL' locally, but it is not exported. - frontend/components/group/yield-dashboard.tsx(48,18): error TS2503: Cannot find namespace 'rpc'. Now all 3 of the original TypeScript errors (4 errors total when including the 4th already fixed in PR #74) are resolved. Front end CI (#54) can now pass cleanly.
