solSignOffchainMessage

Sign a Solana off-chain message. The SDK implements this method for Protocol V1 and V2 through the same public API. Confirm firmware support on the device models used by your integration.


const response = await HardwareSDK.solSignOffchainMessage(connectId, deviceId, {
  path: "m/44'/501'/0'/0'",
  messageHex: '68656c6c6f', // hex of the off-chain payload
});

Params
