   - `switchChain()` now expects `chainId: Hex` instead of `chainId: number | Hex`
   - `createEVMClient()` param option `api.supportedNetworks` now expects hex chain IDs as keys (e.g., `'0x1'`) instead of CAIP chain IDs
   - Event handler types for `connectAndSign` and `connectWith` now use `Hex` for `chainId`
+- **BREAKING** `getInfuraRpcUrls` now returns a rpc url map keyed by hex chain ID rather than CAIP Chain ID ([#152](https://github.com/MetaMask/connect-monorepo/pull/152))
 - The `debug` option param used by `createEVMClient()` now enables console debug logs of the underlying `MultichainClient` instance. ([#149](https://github.com/MetaMask/connect-monorepo/pull/149))
