2. Import path fixes (v1.0.0 breaking change):

   • getDefaultConfig moved to @openfort/react/wagmi subpath
   • useWallets replaced with useEthereumEmbeddedWallet from @openfort/react/ethereum

3. Provider access updated:

   • Replaced client.embeddedWallet.getEthereumProvider() with wallets[0].getProvider() (new v1.0.4 API)
