### Migration Strategies

#### For VeBetterDAO Features

If you depend on VeBetterDAO functionality:

1. **Option 1**: Implement custom hooks using `useCallClause`
2. **Option 2**: Wait for community implementations
3. **Option 3**: Use direct contract interactions

Example custom implementation:

```typescript
// Custom Galaxy Member balance hook
const useGMBalance = (address: string) => {
  return useCallClause({
    abi: GalaxyMemberABI,
    address: GM_CONTRACT_ADDRESS,
    method: 'balanceOf',
    args: [address],
    queryOptions: {
      enabled: !!address
    }
  });
};
```

#### For Removed Utility Functions

Most removed utilities can be replaced with:

1. Direct contract calls using `useCallClause`
2. Thor client methods
3. External libraries (ethers.js, web3.js)
