我调用了硬件的签名成功签名，但是无法将交易广播出去

Start with the issue body's HardwareSDK.evmSignTransaction call, serialize step, and wallet.sendTransaction broadcast path. Reproduce the failure and inspect the returned error and signed payload, then verify that the provider, transaction fields, and broadcast method are compatible. Done means a successfully signed transaction is accepted by the configured network and its hash is returned.
