+# TypeScript Error Fixes for Main Branch
+
+## Issue Summary
+Fixed 4 TypeScript errors in the main branch that were causing frontend CI (#54) to fail and creating noise for developers running typechecks locally.
+
+## Errors Fixed
+
+### Error 1 - Missing import in group-details.tsx
+- **Location**: `frontend/components/group/group-details.tsx:39`
+- **Error**: `error TS2304: Cannot find name 'useOptimisticTransactions'.
+- **Fix**: Added missing import:
+  ```typescript
+  import { useOptimisticTransactions } from "@/hooks/useOptimisticTransactions"
+  ```
+- **Impact**: The optimistic transaction flow in group-details.tsx is now properly typed and functional
+
+### Error 2 - STELLAR_RPC_URL not exported
+- **Location**: `frontend/components/group/yield-dashboard.tsx:15`
+- **Error**: `error TS2459: Module 'useJointSaveContracts' declares 'STELLAR_RPC_URL' locally, but it is not exported.
+- **Fix**: 
+  1. Exported `STELLAR_RPC_URL` from `frontend/components/web3-provider.tsx` along with other Stellar network configuration constants
+  2. Updated `frontend/components/group/yield-dashboard.tsx` to import `STELLAR_RPC_URL` from `@/components/web3-provider` instead of `@/hooks/useJointSaveContracts`
+- **Impact**: yield-dashboard.tsx can now properly read the Stellar RPC URL from the correct location
+
+### Error 3 - Missing rpc namespace import
+- **Location**: `frontend/components/group/yield-dashboard.tsx:48`
+- **Error**: `error TS2503: Cannot find namespace 'rpc'.
+- **Fix**: Added `rpc` to the Stellar SDK import in `frontend/components/group/yield-dashboard.tsx`:
+  ```typescript
+  import {
+    Contract, TransactionBuilder, BASE_FEE, nativeToScVal, xdr,
+    Address,
+    rpc,
+  } from "@stellar/stellar-sdk"
+  ```
+- **Impact**: rpc namespace references now properly resolve, enabling server simulation error checking and transaction response type casting
+
+### Error 4 - LedgerEntryResult type mismatch (from PR #74)
+- **Location**: `frontend/hooks/useJointSaveContracts.ts:662`
+- **Error**: `error TS2339: Property 'xdr' does not exist on type 'LedgerEntryResult'.
+- **Fix**: Added proper type guard for `LedgerEntryResult` before accessing xdr property:
+  ```typescript
+  // Type guard for LedgerEntryResult to safely access xdr
+  let rawXdr = ""
+  
+  if (entry && typeof entry === "object") {
+    if ("xdr" in entry) {
+      rawXdr = entry.xdr
+    } else if (entry.val && typeof (entry.val as any).toXDR === "function") {
+      rawXdr = (entry.val as any).toXDR("base64")
+    }
+  }
+  ```
+- **Impact**: Prevents runtime errors when accessing ledger entry data while maintaining compatibility with the @stellar/stellar-sdk version 15.0.1
+
+## Files Modified
+
+1. **`frontend/components/group/group-details.tsx`**
+   - Added `useOptimisticTransactions` import
+   - Line 19: Added import from `@/hooks/useOptimisticTransactions`
+
+2. **`frontend/components/group/yield-dashboard.tsx`**
+   - Updated `rpc` import
+   - Line 14: Added `rpc` to Stellar SDK import statement
+   - Line 16: Changed `STELLAR_RPC_URL` import from `@/hooks/useJointSaveContracts` to `@/components/web3-provider`
+
+3. **`frontend/components/web3-provider.tsx`**
+   - Exported `STELLAR_RPC_URL` constant
+   - Line 35: Exported `STELLAR_RPC_URL` along with other network constants
+
+4. **`frontend/hooks/useJointSaveContracts.ts`**
+   - Added type guard for LedgerEntryResult
+   - Lines 662-665: Added safe type checking before accessing `entry.xdr`
+
+## Verification
+
+- ✅ `tsc --noEmit` now exits with zero errors
+- ✅ No `@ts-ignore` or `@ts-expect-error` suppressions were used
+- ✅ Each fix resolves the actual missing import/export/type mismatch rather than suppressing errors
+- ✅ `group-details.tsx` optimistic transaction flow manually verified to work correctly
+- ✅ `yield-dashboard.tsx` manually verified to load and display data correctly
+
+## Impact
+
+- **Developer Experience**: Developers running `tsc --noEmit` locally will no longer see pre-existing noise caused by TypeScript errors unrelated to their changes
+- **CI/CD Pipeline**: Frontend CI (#54) can now pass cleanly without being blocked by these pre-existing TypeScript errors
+- **Code Quality**: All four TypeScript errors are now properly fixed rather than being suppressed, improving the overall type safety of the codebase
+
+## Related Information
+
+- This fix complements the fixes in PR #74 (which addressed a related JSX nesting bug in group-members.tsx)
+- All fixes work with the existing @stellar/stellar-sdk version 15.0.1
+- The fixes maintain backward compatibility and follow existing code patterns
+
+Closes #75
