The provider accepts any EIP-1193 method, but not every method is served. Some are answered by the SDK locally, some open the Startale App popup, and some are accepted and then fail. This page is the map, so you find out here rather than at runtime.

​
Standalone applications

Until the user connects, only eth_requestAccounts, wallet_connect, wallet_sendCalls, eth_accounts, eth_chainId, and net_version are served. The other methods on this page, apart from wallet_getCallsStatus, throw 4100. Connect first. Answered locally by the SDK. No popup, no user interaction. Served by the Startale App popup. These prompt the user. Not served. These requests fail. eth_signTypedData_v1, eth_signTypedData_v3, eth_signTypedData (unversioned), eth_signTransaction, eth_ecRecover, personal_ecRecover, wallet_addEthereumChain, wallet_watchAsset, wallet_grantPermissions, wallet_showCallsStatus open the Startale App popup, which shows the method as not supported. Closing it rejects the request with 4001, not 4200, so do not treat every 4001 as the user declining a supported action. wallet_getCallsStatus never reaches the Startale App and is not supported. Do not call it.
Do not build against the unsupported list. Several of these are standard methods a wallet is often assumed to implement, and a library that calls one on your behalf will fail at the point of use rather than at setup. eth_signTypedData_v4 and wallet_sendCalls are the supported equivalents for typed-data signing and batching.

​
Inside a Mini App

The surface is deliberately narrower. Anything not listed throws 4200 Unsupported method. See Mini App wallet integration for the full constraint surface, including why signing from a linked EOA is not possible.

​
Batch status is not pollable

Neither wallet_getCallsStatus nor wallet_showCallsStatus is implemented in either context. wallet_sendCalls resolves with transactionHash and userOpHash once the batch is submitted. If you need a receipt, look it up with your own RPC client.
